银杏(Ginkgo biloba L.)属银杏科植物,其果实亦称白果,具有敛肺平喘、止咳祛痰等功效。国内外对银杏叶、果的化学成分进行了广泛的研究,并取得了一定的应用成果,但银杏外种皮一直被任意丢弃,既浪费了资源,又污染了环境。为此我们对银杏外种皮的化学成分进行了分离和鉴定。 Ginkgo biloba L. is a ginkgo plant, also known as ginkgo fruit, with the convergence of lung asthma, cough expectorant and other effects. At home and abroad, the chemical constituents of Ginkgo biloba and fruit have been extensively studied, and some achievements have been made. However, the seed coat of Ginkgo biloba has been discarded arbitrarily, which is a waste of resources and pollutes the environment. To this end, we have separated and identified the chemical composition of the outer seed coat of Ginkgo biloba.
