1、Electrospray ionization tandem mass spectrometry(ESI-MSn) was applied for simultaneous determination of norditerpenoid alkaloids in the roots of Aconitum kusnezoffii without any chemical isolation.───碱的结构相似,在电喷雾串联质谱中碎裂方式相同,因此根据电喷雾串联质谱结果确定了这些生物碱的结构。
2、Methods:The isolation and purification were carried out by repeated silica gel column chromatography, and the chemical structures were determined by physicochemical properties and spectral analysis.───方法:采用反复硅胶柱色谱、葡聚糖凝胶色谱等分离纯化,通过理化常数和波谱分析鉴定其化学结构。
3、functional character of dispersed pancreatic acini prepared by the method including chemical digestion, mechanical isolation and centrifugal purification was studied.───采用化学消化、机械分离和离心提纯法制备的胰腺腺泡的机能。
