全缘叶元胡(Corydalis repens Mahdl. et Muchld)系罂粟科紫堇属植物的干燥球茎。原野生于北京市郊门头沟,本所栽培室采集后栽种于本所西北旺药用植物试验场。民间用作镇痛药,当地有的单位用它代替延胡索。关于该植物的化学,国内外尚未见报道,所以我们对全缘叶元胡中生物碱进行了化学研究。从它的球茎中分出7种生物碱,通过熔点、比旋度测定、红外光谱和质谱分析,分别证明为普托品、(-)斯阔任、毕扣扣灵、碎叶紫堇碱、(-)四氢黄连碱和两个有待进一步鉴定的碱。实验材料
Whole Corydalis repens Mahdl. et Muchld is a dried bulb of a plant of the genus Papaveraceae. The original wild was found in the Mentougou suburb of Beijing. The cultivation room of the Institute was planted and planted on the experimental plant of the Northwest Xiwang medicinal plant. Folk use as an analgesic, some local units use it instead of Yan Husuo. With regard to the chemistry of this plant, it has not been reported at home and abroad. Therefore, we conducted a chemical study of alkaloids in the whole leaf of Yuanyuanhu. Seven kinds of alkaloids were separated from its bulbs. The results were confirmed by melting point, specific rotation, infrared spectroscopy and mass spectrometry. They were proved to be propanol, (-) Skullen, Bi Kailin, and purpura. (-) tetrahydrocoptimetine and two bases to be further identified. Experimental Materials
