Reaction Conditions:
with Cunninghamella blakesleana in methanol for 120 h;Microbiological reaction;regioselective reaction;
Steps:
2.3 Culture and biotransformation procedures
Mycelia of C. blakesleeana from agar slants (2cm2) were transferred to 100mL of medium and cultured at 30°C with 175rpm for 36h to make a stock inoculum. Then 10mL volume of the inoculum was added to 1000mL of liquid medium, and the flask was placed on rotary shaker operating at 175rpm and 30°C. After 36h of preculture, 100mg of icariin with 2mL methanol added into 2L of culture medium for preparative biotransformation with the final concentration of 50mg/L. The incubation was continued for 5 additional days. The culture was filtered, and the filtrate was extracted with same volume of EtOAc for five times. And the suspension cells of C. blakesleeana (5.2g) were also extracted by using EtOAc (1000mL). Then all extraction of EtOAc were collected and concentrated under the reduced pressure. The residues (1.6g) were applied to an ODS column (200g, 10cm×50cm) and eluted with MeOH-H2O (in a gradient manner from 10% to 90%, at a flow rate of 2.0mL/min). Totally, 90.1mg of icariside II (96.5% purity) was obtained from fraction of 60% MeOH (500mL).
