傅里叶变换红外光谱分析三种彝药材

傅里叶变换红外光谱研究三种彝药材的指纹图谱,并初步分析了它们的有效药物成分和图谱的关系.在金丝杜仲的块根中,淀粉纤维素含量高,而在真金草和回心草中,纤维素和蛋白质的含量更高些.实验发现,金丝杜仲的止血功能和溶血功能可能与所含鞣质类物质和四环三萜类成分有关.真金草的抗梅毒作用可能源于其中的生物碱的生理活性,其活血作用也与四环三萜类物质成分有关,所含多糖和苷则对治疗肝炎有效.回心草的安神作用可能与所含的三萜皂元成分有关,三萜皂元具有安定作用.利用傅里叶变换红外光谱法可以方便、快速和准确地分析中药材的某些有效成分,文章对三种药材的部分药物疗效在分子水平上给出了一定的科学依据.

Study on Three Kind of Yi Ethnic Herbal Medicine by FTIR Spectrometry

The FTIR fingerprint spectra of three Yi Ethnic herb medicines,and the effective composition of herbs were analyzed and studied.The contents of starch and cellulose are high in jinsi duzhong block root,but the zhenjin grass and huixin grass are more abundant of cellulose and protein.The hemostadial action is related to the tannins kind compounds,while an activing blood is related to the tetracydie triterpenoids.The action resisting is related to activity of alkaloid, its active blood is related to tetracycline triterpenoids.The lentinan in the zhenjin grass action to treatment hepatitis is related to triterpenoid sapogenins invariability,calming nerves related to tritepenoid sapogenins.FTIR spectrum is very fast,simple,and reliable to analyze effective composition of herbs.
