The 1950s, modernantibiotics and medical supplies are undoubtedly considered one of the greatestbenefits of human well-being.

During the next 10-15 years, the average lifeexpectancy of the population has increased significantly. Many tumors and viraldiseases become easy to control, and some are lost. In addition to thesebrilliant discoveries in recent decades, studies of antibiotics are fraughtwith recent scientific and economic problems(Berdy et al 2012).Of course,antibiotics make an important contribution to improving the health andwell-being of humans and animals (Carl and Pascal, 2006). Endophytes areimportant as research and application of plant pathology because in some casesplants suffering from endophytes show greater resistance to plant pathogens,especially fungi and nematodes. There are several mechanisms by whichendophytic fungi can interact with pathogens (Zabalgogeazcoa 2008).Many types ofmicrobial populations such as bacteria and fungi bind endophytes to theinternal tissues of the plant. The term “endophyte” was created by DeBary (1866).

It invades the survival of microorganisms in infected planttissues without disturbing the host plant (Schulz and Boyle 2006). Almost allplants have been infected with one or more endophytes (Petrini et al., 1992).These microorganisms produce growth-promoting metabolites, insects andrepellents, anti-phytopathogenic antimicrobials, protection agents under stressconditions and the like (Rya et al., 2007, Rai et al., 2014a, b).

They alsoretain the potential to create this unique secondary metabolite, which can beused in the pharmaceutical, agricultural and other industries. As a result,scientists are interested in the biological exploration of endophytic microbialcommunities of plants from various ecosystems. Actinomyces is Gram-positive,usually a filamentous bacterium, and is the main gateway in the bacterial field(Ludwig and Klenk 2005).EndophyticStreptomyces is the most widely used group in the pharmaceutical andagro-industrial industry (Joseph et al 2012).

Genetic gene genes encodingpolyketide synthase (PKS) or non-ribosomal peptide synthetase (NRPS) are oftenrecorded, and in a few reports an endomorphism of 21-66%, 45-82% and 33-100% isfound. Bacteria are of type I PKS (PKS-I), type II PKS (PKS-II) and NRPS(Matsumoto & Takahashi 2017).We investigated theconstructive interaction of endophysial actinomycetes with plantsA study of livingspace. These natural actinomycetes are an important source of new biologicallyactive compounds and many research groups are involved in their biologicalactivity and industrial applications. This review summarizes the advances inendophytic actinomycetes in northern India, including their diversity andbroad-spectrum biological activity.

  Natural products:For hundreds of years, this drug has been made entirely fromnatural sources and consists of herbs (Paul M. Dewick, 2014). Natural productshave become a rich source of major molecules of drug discovery due to theirhigh chemical diversity and many unique biological activitiesEtc. 2014). The world is endowed with rich medicinal plants.The type and amount of plants that have therapeutic properties are quitestriking. It is estimated that from lichens to towering trees, about 70,000plants are used as medicinal plants.

Herbs provide raw materials for the separationor synthesis of conventional medicines. Due to the presence of many differentchemical compounds of diverse composition, medicinal plants have therapeuticproperties and are found to be secondary plant metabolites in one or more partsof these plants . (Narayan Das Parajapati & Dr.U.Kumar,2003). Medicinal plants:Of the 258,650 higher plants reported worldwide, more than10% are used to treat sick communities (Shinwari 2010). Plants with medicinal properties and effects should havehigher levels of health. (Akerele et al.

1991). Medicinal plants are used toseparate and define bioactive metabolites. (Nisa et al., 2015). Medicinal plants have improved symptoms due to the variouscomposite chemical compositions of secondary metabolites in different parts ofthe plant (Iyer and Devi, 2008).

  INDO-PAK Medicinal plants:·        Cassia fistula commonlycalled as Amaltas·        Trigonellafoenum-graecum commonly called as Methi·        Carica papayacommonly called as Papeeta·        Dioscoreafloribunda commonly called as Ratalo·        Citrulluscolocynthis commonly known as  Korhtumma·        Ferula asafetidacommonly known as Hing·        Caesalpinia Cristacommonly known as Letkanta·        Smilax ornatecommonly known as Ashba·        Styrax benzoincommonly known as LOBAN·        Crocussativus  commonly known as Zafran·        Azadirachtaindica commonly known as Neem·        Ocimumtenuiflorum commonly known as TulsiIndo-Pak Medicinal Plants commonuses: Well known therapeutic properties (Ahmad & Beg, 2001) are commonly available from commonly used medicinal plants. The World Health Organization reports that 80% of the world’s population is heavily dependent on traditional medicine, many of which use plant extracts or their active ingredients (WHO, 1993).Neem (Azadirachtaindica)  may be India’smost useful traditional medicinal plant. Each part of the neem tree has somemedicinal properties and is commercially advantageous.

(Biswas et al., 2002).(Fujiwara et al., 1982), antimicrobial activity (Devakumar and Sukh Dev, 1996),antimalarial (Jones et al., 1994), antipyretic effect (David et al., 1969) ,Spermicides (Sharma et al., 1959), and anti-inflammatory and immune immuneproperties (Nat et al.

, 1991).Cassia fistula (Amaltas)  have been used to treat skin problems suchas vitiligo, wigs, liver disease, tubercles, wounds and diabetes (Alam et al.,1990, Asolkar et al., 1992). It also contains antioxidant activity(Luximon-Ramma & Bahorun et al., 2002). According to cytological studies,the antitumor activity of Cassia fistulae seed extract suggests that areduction in mitogenic activity may be the dominant mechanism for tumorigenesis(Gupta et al., 2000).

Cassia fistula extract is active against many bacteria,namely E. coli, B. subtilis, B.subtilis, M. smegmatis, Klebsiella pneumoniae,P. aeruginosa and Perumal et al., 1998), antifungal activity (Duraipandiyan andIgnacimuthu 2007), the ovicidal and larvicidal activities of the methanolextract of Cassia obtusiloba, and found that the extract is more deadly to thelarvae of Anopheles stephens (Govindarajan, Jebanesan et al. (Pradeep, Mohan etal.

, 2007) provide scientific evidence for cassia fistulas Prevention andTreatment of Liver Disease Cassia fistula plants may contain heavy metalelements such as Cu, Co, Ni, Pb, Zn, Cr, Fe, Mn, F and K2O, the concentrationof which depends on soil mineral status (Biswas Cassia fistula enhances humoralimmunity (Nafisa and Shahana et al al., 2008). (Sartorelli, Andrade Samanta etal., 2007) Shows lower toxicity than conventional drugs.(Ammal, George et al.

, 2007) described the efficacy ofcassia fistula extract against the inhibition of cholesterol growth in growthexperiments using cassia extract in a high cholesterol solution. It shows thatthe crystallization of the inhibition.(Bahorun, Neergheen et al., 2005) demonstratedanti-cancer effects of Cassia fistulae.

Cassia fistula suppresses theproduction of inflammatory mediators “Leukotriene” is a mechanisminvolved in antirheumatic therapy that enhances the traditional use of antirheumaticsin Pakistan (Sunil Kumar and Müller, 1998). The antidiabetic effect of cassiaseed extract (Esposito Avella, Diaz et al., 1991) examined the fistula. Dioscorea floribunda(Ratalo), another medicinal plant, allused for vegetative propagation (Bammi, RK et al., 1982). Diosgenin is acomponent of Dioscorea floribunda (Hoyer et al., 1975). The effect of Dioscoreafloribunda is based on the action of various steroidal saponins (potatodiosgenin and aglycone).

(Dias,Correia et al., 2007) shows tuberous apogenin vasorelaxation in endothelialcells isolated from the superior mesenteric artery in rats. It has ananti-inflammatory effect on the extract and therefore becomes a very usefultopical ingredient for skin creams used to mature and dry skin types (Anthony al.

, 2002). The steroid properties of tuberosum saponin have demonstratedthe use of Dioscorea floribunda and other potato species in the UK to combatrheumatoid inflammation and pain (Anthony C. et al., 2002).

(Dioscoreafloribunda) extract on HER2-expressing tumors (Chiang, Way et al., 2007).Potato sapogenin, produced by other members of the families Dioscoreafloribunda and Dioscoreacea, can be used as starting material for theproduction of steroidal compounds such as cortisone, pregnenolone and progesterone(Marker and Krueger 1940). Senescence is scientifically recognized in theanti-aging preparations of Dioscorea floribunda (Liviero and Allec 2002) andAnti-Wrinkle Treatment (Besne 2003) and Cosmetic Surgery (Eymard M, 2004) foranti-aging and traditional treatment. Another drug is Citrullus colocynthis(Korhtumma). (Sangameswaran, Balakrishnan et al., 2008) examined theirhypoglycemic effect on alloxan-induced diabetic rats. It has the potential fortreatment of human breast cancer (Tannin-Spitz, Grossman et al.

, 2007). Theantiparasitic effect of E. coli has been studied in domestic animals inPakistan (Farooq, Iqbal et al.

, 2008). Its extracts also showanti-hyperglycemic effects that support the traditional use of E. coli as anantidiabetic (Sangameswaran, Balakrishnan et al., 2008). Certainmedical attributes are given to Ocimum sanctum  (Tulsi) (Sarkar et al.

, 1994). Infectious andlarvicidal acts are shown among the Tulsi products and the essential oilsagainst mosquitoes which have anti-malarial effects (Mohan et al., 2011)(Prakash and Gupta, 2005).Antifungalactivity is at St. Basil is also against Aspergillus Nigeria and his aquaticextract, Tulsi, is found in patients with viral encephalitis (Prakash andGupta, 2005). Total plant decoction reduces levels of blood glucose (glucose)levels and this is said to be controlling diabetes (Nagarajun et al.

, 1989). Itis recommended that Tulsi be reactive to dog lubricants (Late 1993),Scorpionbid (Prakash and Gupta, 2005) and insect bites (Pandey and Anita 1990).Tulsi plant leaves also show that adaptability, analgesic, antiocephaplus andantioxidant in experimental animals (Khanna N, Bhatia J. 2003) have also beenfound. Basil Naofa also has fertility effects (Khanna et al.

, 1986). Endophytes:Endophytes are present in microorganisms in the internaltissues of living plants with no negative effects and different biologicalproperties of different diseases are shown. They are considered as potentialsources of novelty products, used in medicine, agriculture and industry tomodify more and more bioactive natural products from micro-organisms. (Guo etal. 2011).The link between fungi and plants started very early inthe evolution of terrestrial plants, and this association affected their evolution(Suryanarayanan, 2017). Since the late 19th century, fungi have been found inasymptomatic plant organs (eg Guerin, 1898).

Plants are fungi that infectplants without causing symptoms. The fungi belonging to this group areubiquitous and the plant species not associated with fungal endophytes areunknown. In addition, endophytic fungi have great biological diversity and someplant species differ from 100 endophytic fungi (Zabalgogeazcoa 2008). Many can synthesize active biological compounds that plantscan use to protect human pathogens, and some of these compounds have proven tobe useful for new drug discoveries.

Recent studies have shown hundreds ofnatural products including alkaloids, terpenoids, flavonoids, steroids fromendophytes. To date, most of the endophile natural products are bioactivecompounds with various functions such as antibiotics, anti-cancer agents andbiological control agents. So far, they have not been thoroughly audited aboutthe nature of the treatment. Bioactive metabolites may only produce oneendophyte. Therefore, the role of endophytes in the production of newstructures for drug development is getting more attention. (Joseph and Priya,2011).

  Actinomycetes:With more than 70 years Actinomycetales have beenrecognized as an important source of bioactive natural compounds. From around18,000 bacteric bioactive compounds identified, more than 10,000 bacteriareported the genus Actinomyces (Berdy et al., 2012).Actinomycetes is a good source of non-active non-activecarbide and can be used as a potential drug candidate to develop antibiotics.Many antibiotics are well known, such as tetracycline, erythromycin, vancomycinand streptomycin, from the secondary metabolism of actinomycetes. In additionto antibiotics, other types of bacteria are reactive immune agents, resistantagents of doxorubicin and bleomycin, avermectin avermectin and antifungalCompound Nystatin (Weber et al.

, 2015).These periodic producers are occasionalprocedures that occasionally produce various metabolites from Streptomyces.Most of the actinomycetes that produce rare and active antibiotic antibioticsare rare, such as those that produce dynamic proteins and those that produceactinomycetes maduratia. (Matsumoto and Takahashi, 2017).

One of themost significant sources of antibiotics and other bioactive substances is thehigh value value of the actinomycetes. It represents two thirds of the totalamount of antibiotics known out of this Gram-positive branching spor with thefilamentous inflamous bacterial microflora mycobacteria. In actinomycetes,Streptomyces spp. The most commonly used source of all types of antibiotics.Along with the production of antibiotics, another important element of actinomycetesthat has been studied is their ability to degradate lignin – the mostcomplicated bipolar.

Woodin bio degradation is considered a significantphenomenon because it plays a key role in the carbon cycle (Ahmad et al.,2016). Endophyticactinomycetes:The microbes that are acting at endophytic metabolicsymptoms live in healthy tissues of living plants without clinically detecteddisease symptoms and can be separate from the plant tissues that have thesterilization surface (Nimnoi and Pipslip, 2009). Actinomycetes activities haveregard to the activities of new bioactive natural compounds that could be usedas new drugs where those with pathogenic resistance are obesity with rapidlyacquired resistance.

(Gangwar et al 2014).One of the most active and most active antibiotic sourcesof antibiotics and other biological active substances is of high commercialvalue. The cultural diversity of endophytic activity activities related totropical, native plants is not well researched. Actinomycetes microbiologistactivity has not been inactive, but in recent years it has been found to be aneffective producer of antibiotics and new lead compounds to develop newmedicines. Many secondary metabolites have been made available especially tothem, not only that they are useful for plants but also have economicimportance for people (Kumar and Jadeja, 2017).Endophytic microbes have been identified as fungi andbacteria, including actinomycetes (Strobel and Daisy 2003).

The aerobicactinomycetes, gram-positive, spray containing mutual and mutual bacteria, aresecondary in metabolites and enzyme production (Masand et al 2015).These actuates about mutual associations with uniqueplanting plant species can produce metabolites that can be used as numerousantimicrobial (Yan et al. 2010; Yang et al. 2015; Igarashi et al. 2011; Djinniet al. 2014), resistant compounds (Yu et al 2011; Savi et al. 2015),antidiabetics (Akshatha et al.

2014), bio-functioning agents (Li et al. 2014)and plant growth promoters (Shutsrirung et al. 2013).   Endophyticactinomycetes of Medicinal plants:           Plant specie     Actinomycete taxa              References Azadirachta indica   Streptomyces, Streptosporangium, Microbispora, Streptoverticillium, Saccharomonospora, Nocardia Verma et al.

Many economically important actinomycetes are known to produce anarray of biologically active substances, such as antibiotics, vitamins andenzymes (Mccarthy and Williams, 1992).Antitumoractivity:Many naturalproducts from plants, microorganisms, and marine sources were identified asanticancer agents. Some examples of the potential of endophytic actinomyceteson the production of anticancer agents are reviewed. Paclitaxel is anantimicrotubule drug used for the treatment of ovarian and metastatic breastcancer.

Food and Drug Administration has approved Taxol for the treatment ofadvanced breast cancer, lung cancer, and refractory ovarian cancer (Kumar andJadeja 2016).lupinacidin C is anew anthraquinone derivative antibiotics isolated from the endophyticactinomycete Micromonospora lupini. Lupinacidin C exhibited the mostpotent inhibitory effects among the congeners on the invasion of murine coloncarcinoma cells into the reconstituted basement membrane (Igarashi et al.

2011).Ansamitocin is agroup of ansamycin antibiotics show potent antitumour activity. Ansamitocin wasisolated from endophytic actinomycetes Nocardiasp. No. C-15003 (N-l).

Structures of ansamitocin were found to be similar to maytansine and relatedmaytansinoids which shows strong cytotoxic and antineoplastic activities (Eiji et al. 1977).Againstnosocomial pathogens:A varied number ofendophytic Streptomyces strains were recovered from different tissues ofP. hysterophorus. Majority of the strains exhibited significantantimicrobial activity against nosocomial pathogens.

(Tanvir et al 2013).Antibacterialactivity:Actinomycetes haveantibacterial activity against pathogenic bacteria. They produce antibiotics,herbicides, pesticides and enzymes like cellulose and xylanase used in wastewater treatment. They contain enzymes such as lecithinase, lipase and nitratereductase, H2S production, amylase, gelatinase, DNase and urease. (Ahmed et al2016).   Anti-MRSAactivity:The increasingresistance to known antibiotics developed by bacterial pathogens is one of thegreatest threats to human health worldwide.

Methicillin-resistant Staphylococcus aureus (MRSA) infectionshave received much attention and are still a major cause of death.(Martín et al 2012).  Strainsof Arthrobacter isolattef fromproduce kocurin which is potent anti-MRSA compound (Palomo et al 2013). Antiviralmetabolites:Some endophyticactinomycetes also possess the ability to inhibit harmful viruses. Anendophytic Jishengella endophytica strain 161111 isolated from the root of themangrove plant Xylocarpus granatum shows antiviral activity.Antimycoticactivity: Saadamycin is anantimycotic compound isolated from endophytic actinomycetes Streptomyces sp.

Hedaya48. This strain exhibited significant antimycotic activity againstdermatophytes and other clinical fungi (El-Gendy et al. 2010).Larvicidal andantimalarial activityStreptomyces albovinaceus and S.

badius isolatedfrom plants of family Asteraceae were also found to havesignificant larvicidal potential against first and fourth instar stagesof Culexquinquefasciatus (mosquito larvae).They illustratedstrong larvicidal activity (80–100 % mortality) of six isolates while fourisolates showed potent larvicidal activity (100 % mortality) at the fourthinstar stage. (Golinskaet al 2015).    Conclusion:Bioactive naturalcompounds produced by endophytic actinomycetes have been promising potentialusefulness in safety and human health concerns, although there is still asignificant demand of drug industry for synthetic products due to economic andtime-consuming reasons (Kumar and Jadeja 2016). We decided to focus attention on endophytes as a prospective newsource of novel microbes because the actinomycetes of endophytic plant have confirmedto be significantly different from those found in soilenvironments.
