| 摘要: |
| 对黄花变异黄芪的化学成分进行了系统预试，对其总生物碱进行了提取和分段萃取，并用TLC法对分段萃取物进行了检查。结果表明，黄花变异黄苠含有糖、有机酸、酚类、鞣质、氨基酸、蛋白质、甙类或多糖、皂甙、生物碱、黄酮、蒽醌、香豆素、萜类、内脂、甾体等成分，不含挥发油、油脂、氰甙和脂肪族硝基化合物；黄花变异黄芪的生物碱主要以强极性生物碱为主，约占总生物碱的97.25％；对三段萃取物的TLC检查发现，黄花变异黄芪中含有苦马豆素，且主要存在于乙酸乙酯萃取部分和正丁醇萃取部分。 |

| Abstract: |
| Through systematic pre-experiment on chemical composition (yellow flower),gain and extract ion of general alkaloids of Astragalus variabills Bunge,test of extraction by TLC,the result indicated that it contained saccharide、organic acid,polyphenolics,tannins,amino acid,protein,glycosides or polysaccharides,saponins,alkaloid,Flavonoids,anthraquinones,coumarin,terpenoids,steroids,no naphtha and lipin,cyanogenetic glycoside and aliphatic nitro compounds.The Alkaloids of Astragalus variabills Bunge (yellow flower) was the main high polar part,accounting for about 97.25%.Swainsoine was detected in Astragalus variabills Bunge (yellow flower) when tested by TLC in its extraction in three parts,and was mainly in Ethyl acetate and n-Rutanol. |
