530CHEMICAL COMPOSITION OF METHANOL EXTRACT OF ENDOPHYTIC FUNGI, ALTERNARIA SP. OF TEBEBUIA ARGENTEA AND THEIR ANTIMICROBIAL AND ANTIOXIDANT ACTIVITYWe report the identification of the bioactive compounds in endophytic fungus, Alternaria sp methanol extract in 6th fraction in GC-MS analyses. Totally 11 peaks were identified, they are acetic acid, phenylmethyl ester (1), phenol, 2,4-bis(1,1- dimethylethyl)- (2), diethyl Phthalate (3), dodecanoic acid, 1-methylethyl ester (4), 2-pentadecanone, 6,10,14-trimethyl- (5), 1,2-benzenedicarboxylic acid, bis(2-methylpropyl) ester (6), pentadecanoic acid, 14-methyl-, methyl ester (7), 2- benzenedicarboxylic acid, butyl 2-methylpropyl ester (8), 10,13-octadecadienoic acid, methyl ester (9), 9-octadecenoic acid (Z)-, methyl ester (10) and 1,2-benzenedicarboxylic acid, mono(2-ethylhexyl) ester (11). They exhibited strong antioxidant and antibacterial activity in combination of these compounds. The present approach offers a strategy for accelerating research on natural products and their pharmacological applications endophytessiet@gmail.comResearch5112014 Tabebuia argentea,endophytes,Alternaria sp,GC-MS,antioxidant,antibacterialGovindappa M,Prathap S,Vinay V,Channabasava REndophytic Natural Product Laboratory, Department of Biotechnology, Shridevi Institute of Engineering & Technology, Tumkur 572 106, Karnataka, India,Endophytic Natural Product Laboratory, Department of Biotechnology, Shridevi Institute of Engineering & Technology, Tumkur 572 106, Karnataka, India,Endophytic Natural Product Laboratory, Department of Biotechnology, Shridevi Institute of Engineering & Technology, Tumkur 572 106, Karnataka, India,Endophytic Natural Product Laboratory, Department of Biotechnology, Shridevi Institute of Engineering & Technology, Tumkur 572 106, Karnataka, India
