COMPARATIVE STUDY OF OCIMUM BASILLICUM AND ITS ENDOPHYTIC ACTINOMYCETES STREPTOMYCES FLAVOVIRIDIS A3WK: EVALUATION OF ANTIOXIDANT, ANTI-INFLAMMATORY AND ANTIMICROBIAL ACTIVITYAbstract
Endophytic actinomycetes are the potential source for obtaining novel bioactive compounds. Present study evaluates the chemical constituents in Ocimum basillicum and its endophytic actinomycetes. Eleven endophytic actinomycetes were isolated from O. basillicum plant. Among eleven, one isolate was characterized by 16S rRNA and identified as Streptomyces flavoviridis A3WK. A comparative analysis of the FT-IR, GC-MS, antibacterial, antioxidant and anti-inflammatory properties of plant and endophytic actinomycetes extracts was conducted. 12 compounds each of Streptomyces flavoviridis A3WK and O. basillicum were identified by GC-MS. The FT-IR and GC-MS analysis reveals that S. flavoviridis A3WK has more antimicrobial, antioxidant activity and anti-inflammatory properties compared with the results of O. basillicum. Over all the activity of the endophytic actinomycetes was more compared to that of the O. basillicum extracts. The study reveals to show that the existence of endophytic actinomycetes may enhances medicinal value of the medicinal plants, and hence such studies help in the study of endophytic actinomycetes as well as their relevance in host plant.
