The ethanol extract was dissolved with HCl, the acidic extract was basified to pH9-10 with NH_3-water and extracted with CHCl_3 to give total alkaloids. five alkaloids were isolated with column chromatography and preparative thin-layer chromatography, and three of them were identified as dehydrocorydaline、 corynoline and dihydrosanguinarine on the basis of spectral analysis MS,~1H-NMR,~(13C-NMR and physicochemical properties. All of them were found for the first time from this plant.

为研究灰绿黄堇的化学成分，本文将灰绿黄堇乙醇提取物采取酸提取、碱游离后萃取的方法得到总生物碱，然后利用柱色谱、制备薄层色谱等方法分离、纯化了灰绿黄堇中5种生物碱，并利用IR、MS、~1H-NMR、~(13)C-NMR等方法鉴定了其中的3种，分别为去氢紫堇碱、紫堇灵、二氢血根碱，均为首次在此植物中发现。
