Abstract

Six triterpenoid acids were isolated from the stems of Kadsura longipedunculata, collected in Kuangxi province. Four of them were new compounds and assigned as (24Z)-3-oxo-12α-acetoxylanosta-8,24-dien-26-oic acid (1), (24Z)-3-oxo-12α-hydroxylanosta-8,24-dien-26-oic acid (2), (24Z)-3-oxo-14(13→12)abeo-lanosta-8,13(18),24-trien-26-oic acid (3), and (24Z)-3-oxo-13β-hydroxy-14(13→12) abeo-lanosta-8,24-dien-26-oic acid (4). Compounds 3 and 4 were named neokadsuranic acids B and C, respectively.
