从细柱五加叶中分离得到了四个羽扇豆烷型三萜苷元及五个对应的苷类化合物. 根据其理化性质和波谱数据, 鉴定出其化学结构分别为impressic acid (1), 3α, 11α-dihydroxy-23-oxo-lup-20(29)-en-28-oic acid(2),3α, 11α, 23-trihydroxy-lup-20(29)-en-28-oic acid(3), 五加苷元 (acankoreagenin, 4), 3-O-β-D-glucopyranosyl 3α,11α-dihydroxylup-20(29)-en-28-oic acid(5), acantrifoside A(6), acankoreoside D(7), acankoreoside B(8) 和五加苷(acankoreoside A, 9), 其中化合物1 3 和化合物5 是首次从细柱五加中分离得到.
Four lupine alkane triterpenoid glycosides and five corresponding glycosides were isolated from the leaves of five-leaf spica, and their chemical structures were identified as impressic acid (1), (29) -en-28-oic acid (2), 3α, 11α, 23-trihydroxy-lup- 20 Acankoreagenin (4), 3-O-β-D-glucopyranosyl 3α, 11α-dihydroxylup-20 (29) -en- 28-oic acid (5), acantrifoside A (7), acankoreoside B (8) and acankinoside A (9). Among them, compound 13 and compound 5 were isolated for the first time.
