Isolation and Structure Elucidation of Neokadsuranic Acid A, the First Triterpenoid with the 14 (13-->12) abeo Lanostane Skeleton, and (24Z)-3-Oxo-lanosta-8,24-dien-26-oic Acid1.
Neokadsuranic acid A, which is the first triterpenoid with the 14(13-->12) ABEO lanostane skeleton, was isolated from KADSURA HETEROCLITA together with (24 Z)-3-oxo-lanosta-8,24-dien-26-oic acid. The present paper deals with the isolation and structure elucidation of these two new compounds.
