夏天无系罂粟科紫堇属无柄紫堇Cordalis decu-mbens(Thunb)Pers.(Corydlis amabilis Migo)的干燥块茎。有人曾从江西产夏天无中分离到了原阿片碱、右旋四氢巴马丁、紫堇碱、毕扣扣灵、棕榈碱等,其中原阿片碱含量最高。作者采用新的工艺流程,可简便从夏天无总生物碱中提取原阿片碱。一、材料及仪器夏天无总生物碱由江西余江制药厂提供。元素分析用1106型仪测定,IR用岛津IR-440型红外光谱仪。二、工艺流程 In summer, the dry tubers of Papaveraceae Corydalis sessilis Cordalis decu-mbens (Thunb) Pers. (Corydlis amabilis Migo) were absent. Some people have isolated raw materials such as protocaine, D-tetrahydropalmatine, purpuricine, bicarbine, and palmitine from the summer of Jiangxi Province, among which the content of protopine is the highest. The authors used a new process to easily extract protopine from total alkaloids in the summer. First, materials and instruments No total alkaloids were provided by Jiangxi Yujiang Pharmaceutical Factory in the summer. The elemental analysis was performed using a Model 1106, IR Shimadzu IR-440 infrared spectrometer. Second, the process
