Isolation and Screening of Resveratrol Producing Endophytes from Wild Grape Cayratia Trifolia

The aim of the present study was to obtain endophytes strains with effective resveratrol production from wild grapevive Cayratai trifolia in Gujarat, India. 30 strains of endophytes were isolated, including 20 fungus and 10 bacteria. The distribution of endophytes were found in different tissues and organ. The presence of the resveratrol produced by endophytes were confirmed by biochemical test like ferric chloride-potassium ferricynaide colour reaction and quantitative confirmation confirmed was done by Thin layer chromatagraphy, however some endophytes-free samples from the same species also contained resveratrol, usually in reduced concentration. 21 fungal and 6 bacterial isolates showed positive potential for the production of resveratrol. This observation represents the first report of the resveratrol from the Cayratia trifolia.
