Microbial transformation of silybin A (1) and silybin B (2), the major hepatoprotective flavonolignan diastereomers from the fruits of Silybum marianum, with the culture broth of Trichoderma koningii gave two pairs of glucosylated derivatives. Their structures were identified as silybin A 3-O-beta-D-glucopyranoside (3), silybin A 7-O-beta-D-glucopyranoside (4), silybin B 3-O-beta-D-glucopyranoside (5) and silybin B 7-O-beta-D-glucopyrano side (6) by spectroscopic methods.

Glucosylation of silybin by plant cell cultures of Papaver somniferum var. setigerum
Abstract Cellcultures of Papaversomniferum var. setigerum were shown to carry out the biotransformation of silybin into silybin -7-O-β- d -glucopyranoside .
摘要 Papaver somniferum var. 的细胞培养物。显示 setigerum 将水飞蓟宾生物转化为水飞蓟宾 -7-O-β-d-吡喃葡萄糖苷。
