销承嘏:中国延胡索生物碱,第Ⅱ报中国生理学杂志,1929,3,69内容摘要——接第Ⅰ报,由第Ⅰ部分中曾分离出延胡索碱 A 和 D.第Ⅲ部分是酚性的化合物,可溶于氢氧化钠溶液,自其中又分离出二种新生物碱,称为延胡索碱 F 和 G。延胡索碱 FC_20H_(23)O_4N 或 C_(20)H_(24)O_4N,是无色板状结晶体,熔点237℃,[α]D-250°,难溶于有机溶剂(氯仿除外),但易溶于热有机溶剂中,可能为右旋的 Corypalmine.延胡索碱 G 为柱状结晶体,熔点237℃,[α]D+300°,易溶热氯仿,但仅微溶于其他热有机溶剂中。第Ⅳ部份中则分离出延胡索碱 H,为片状结晶体,熔点153℃,不溶于水,可溶于酒精或氯仿,其氢溴酸盐的熔点为228℃。(林摘)
Sales contractor: China Corydalis alkaloids, Part II Chinese Journal of Physiology, 1929, 3, 69 Abstract – Following the first report, isolated from the first part of the fumarate A and D. Part III is phenolic The compounds are soluble in sodium hydroxide solution from which two new alkaloids, also known as fumarate F and G, are isolated. Fumaric acid FC_20H_(23)O_4N or C_(20)H_(24)O_4N is a colorless, plate-like crystal with a melting point of 237°C, [α]D-250°, insoluble in organic solvents (except chloroform), but soluble In a hot organic solvent, Corypalmine, which may be dextrorotatory, is a columnar crystal with a melting point of 237° C., [α]D+300°, and readily soluble in chloroform, but only slightly soluble in other hot organic solvents. In part IV, fumarone H is isolated as a flaky crystal with a melting point of 153°C. It is insoluble in water and soluble in alcohol or chloroform. The melting point of its hydrobromide salt is 228°C. (Forest pick)
