金莲花(Trollius Chinensis Bge)系毛茛科植物,它做为我国北方植物抗菌药已收载于中国药典七七版一部。北京大学生物系于1974年已从金莲花中分离出有效成分两种黄酮甙。由于它们是多羟基衍生物,所以亲水性较强,微显酸性,遇碱或空气易氧化开环。在制备针剂过程中,对除净鞣质,提高纯度增强稳定性带来一定困难。为了扩大该药 Trollius Chinensis Bge is a family of Ranunculaceae plants. It has been included in the Chinese Pharmacopoeia seventy-seventh edition as a plant antibacterial agent in northern China. In 1974, Peking University’s Department of Biology had isolated two effective flavonoids from the lotus flower. Because they are polyhydroxy derivatives, they are more hydrophilic and slightly acidic. They are easily oxidized and open in the presence of alkali or air. In the process of preparation of injections, it is difficult to increase the stability and stability of the purified tannins. To expand the drug
