3.2.1.189 | 3-O-[alpha-L-Rha-(1->4)-[alpha-L-Rha-(1->2)]-beta-D-Glc]diosgenin + 3 H2O |
3-O-[alpha-L-Rha-(1->4)-[alpha-L-Rha-(1->2)]-beta-D-Glc]diosgenin is the the main dioscin in the rhizome of Dioscorea nipponica. The dioscin-glycosidase gradually hydrolyzes either the 3-O-alpha-L-(1->4)-Rha or the 3-O-alpha-L-(1->2)-Rha from dioscin into 3-O-alpha-L-Rha-(1->2)-beta-D-diosgenin or 3-O-alpha-L-Rha-(1->4)-beta-D-diosgenin, further rapidly hydrolyzes the other alpha-L-Rha into the main intermediate products of 3-O-beta-D-Glc-diosgenin, and subsequently hydrolyzes these intermediate product into aglycone as the final product |
