银杏落叶化学成分研究
Studies on Chemical Constituents of Fallen Leaves of Ginkgo biloba
摘要
Abstract
Twenty-two compounds were isolated from the fallen leaves of Ginkgo biloba by silica gel and Sephadex LH-20 column chromatography. The structures were elucidated by physico-chemical and spectroscopic methods as ginnol (1) , octacosanoic acid (2) .palmitinic acid (3) ,heptatriacontane (4) .tetracosane (5) ,4,10-nonacosanediol (6) ,β-sitos-terol (7) .daucosterol (8) .ginkgolide A (9) ,ginkgolide B (10) .ginkgolide C (11) .bilobalide (12) ,p-hydroxybenzo-ic acid (13 ) , shikimic acid (14 ) , genkwanin (15 ) , apigenin (16 ) , ginkgetin (17 ) , isoginkgetin (18) , sciadopitysin (19) ,bilobetin (20) ,rutin (21) and mannitol (22). Among them,compounds 2,4-6 and 22 were isolated from this plant for the first time. The results are helpful for the comprehensive utilization of ginkgo tree resources.关键词
