    • The preparative scale biotransformation: The preparative scale biotransformation of 1 by P. cactorum ATCC 32134 were carried out by a two-stage procedure in potato dextrose medium (PDA). Cultures were incubated with shaking at 180 rpm at 28 °C on rotary shakers. one milliliter of inoculum derived from 24 h old stage I culture was used to initiate stage II cultures, which were incubated for 24 h before receiving 5 mg of ruscogenin in 1 ml of acetone, a total of 120 mg of 1 was distributed evenly among 24 culture flasks, and incubations were conducted as before. The cultures were extracted with EtOAc at 120 h after addition of substrate. The extract was subjected to silica gel column chromatography eluted with chloroform-methanol (10:1, v/v) to afford the product (compound 4, 30 mg).
