Abstract

The MeOH extract of aerial parts of Flourensia riparia Grisebach (Asteraceae) afforded a sesquiterpene lactone, 4beta-hydroxy-4,10alpha-dimethyl-7alphaH,8alphaH-eudesman-11-ene-8,12-olide, together with septuplinolide, its isomer at positions C-5 and C-10. In addition, known flavonoids, p-hydroxyacetophenone derivatives, carabrone and isoalantolactone were identified. Three known flavonoids and a benzofuran were isolated from Flourensia campestris Wedd.

摘要

河岸弗洛伦西亚菊（菊科）地上部分的甲醇提取物得到一种倍半萜内酯，4β-羟基-4,10α-二甲基-7αH,8αH-桉叶-11-烯-8,12-内酯，以及七叶内酯，其在C-5和C-10位的异构体。此外，还鉴定出了已知的黄酮类化合物、对羟基苯乙酮衍生物、卡拉布酮和异土木香内酯。从野地弗洛伦西亚菊中分离出三种已知的黄酮类化合物和一种苯并呋喃。
