ABSTRACT
Biotransformation of Echinocystic acid (EA,1) using G. roseum CGMCC 3.3657 has been investigated, which leads to the isolation and identification of two novel Echinocystic acid derivatives, 4, 16α-dihydroxy-3,4-seco-olean-12-en-3,28-dioic acid (2) and 16α-hydroxy, A-homo-3α-oxa-olean-12-en-3-one-28-oic acid (3). Their structures have been elucidated by analysis of spectroscopic data. This biocatalysis could serve as an efficient tool complementary to classical chemical methods for the transformation of EA.
