()-(2 R,3S)-DIHIDROKUERSETIN, SUATU PRODUK BIOTRANSFORMASI (-)-EPIKATEKIN OLEH JAMUR ENDOFIT Diaporthe sp. E

Andria Agusta

Abstract


The endophytic fungus Diaporthe sp.E show a unique ability to biotransform (-)-epicatechin into (-)-(2R,3R,4R)-leucocyanidin in a semisynthetic medium. Extension of the incubation time gave a major product (-)-(2R,35)-dihydroquercetin which was identified by spectroscopic methods.

Keywords


Camellia sinensis, jamur endofit, Diaporthe sp. E, biotransformasi. (-)-epikatekin, (-)-2R,3R,4R-leukosianidin, (-)-2R,3S- dihidrokuersetin.
