[Abstract]  Various parts of the caper tree Capparis decidua have found application in traditional medicine. The isolation and structural elucidation of the codonocarpine type alkaloids contained in the root bark, however, is not trivial and has probably led to misinterpretation in the past. This protocol describes the extraction and chromatographic separation of the four major alkaloids of the root bark of Capparis decidua. The delivered samples of cadabicine, codonocarpine, isocodonocarpine and capparidisinine were suitable for their unambiguous structural elucidation by NMR, MS and MS/MS. [摘要]  刺槐树Capparis蜕膜的各个部分已经在传统医学中得到应用。然而,根皮中所含的密码子类生物碱的分离和结构阐释并不是微不足道的,并且可能导致过去的误解。该方案描述了Capparis decidua的根皮的四种主要生物碱的提取和色谱分离。递送的cadabicine,codonocarpine,异香豆香碱和capparidisinine的样品适合通过NMR,MS和MS / MS明确的结构阐明。

背景 Capparis id藜树分布在非洲,中东和南亚的干旱地区,其中植物的各个部分通常用于当地民间药物治疗各种疾病。例如,根皮被应用为驱肠和泻药,并且已经显示其酒精提取物具有显着的抗菌和抗真菌活性(Singh等人,2011; Singh和Singh,2011; Tlili等人,2011; Mohammed等人,2015)。
    Ahmad 等人。 (1985; 1986; 1987; 1989; Arif,1986)深入研究了Capparis decidua的根皮提取物,并发表了几种结构的密码子生物碱。这些结构中的一些不符合我们对这种生物碱的生物合成的理解。此外,我们不相信给定的分析数据及其解释给出了结构性声明的明确证据(Bienz et ...
