3'-O-β-D-(4'-O-methylglucopyranosyl)-flavan-4-ol and method of preparing 3'-O-β-D-(4'-O-methylglucopyranosyl)-flavan-4-ol

摘要

The scope of the notification is 3'-O-ss-D-(4"-O-methylglucopyranosyl)-flawan-4-ol and the production method of 2-formula 3'-O-ss-D-(4"-O-methylglucopyranosyl)-flawan-4-ol. This means that the strain of Isaria fumosorosea KCH J2 is introduced into the substrate suitable for shredded mushrooms. At least 72 hours later, a substrate of model 1 3'-methoxyfenone dissolved in an organic solvent mixed with water shall be introduced into the farm. The transformation takes place in temperature from 20 to 30 degrees Celsius,with continuous shaking for at least 96-hour periods. Another product is extracted with an organic solvent that does not mix with water and purified chromatographically.
