Tupichigenin A, a new steroidal sapogenin from Tupistra chinensis
Abstract
From the underground parts of Tupistra chinensis, a novel polyhydroxylated spirostanol sapogenin, tupichigenin A [(20S, 22R)-spirost-25(27)-ene-1beta,2beta,3beta,5beta- tetraol] (1), was isolated and determined structurally on the basis of spectroscopic methods. Also isolated was the known steroidal sapogenin (20S, 22R)-spirost-25(27)-ene-1beta,2beta,3beta,4beta, 5beta, 7alpha-hexaol-6-one (2).
