PMID 26341046

Abstract

Fourteen novel 14,15-diseco-18-nor-pregnane-type steroidal glycosides, mooreanoside A-C (1-3) and mooreanoside F-P (6-16) and two new 14,15-diseco-pregnane-type steroidal glycosides, mooreanoside D-E (4-5) were isolated from the roots of Cynanchum mooreanum Hemsl. Their structures were determined on the basis of spectroscopic and chemical analysis. Compounds 1-6, 8-10, 12-14 and 16 were tested for their immunological activities in vitro against Con-A induced proliferation of mice splenocytes.
