Preparative separation of elatine in Delphinium shawurense was achieved for the first time using high-speed countercurrent chromatography (HSCCC). The separation was performed with a solvent system composed of ethyl acetate-chloroform-methanol-water (3:0.1:2:3, v/v) using the lower organic phase as a mobile phase under a revolution speed of 800 rpm. This yielded 72 mg of elatine at over 97% purity with an approximately 95% recovery. The chemical structure was identified by MS and NMR.
首次采用高速逆流色谱法(HSCCC)对短距翠雀花中的刺桐碱进行了制备分离。分离采用由乙酸乙酯 - 氯仿 - 甲醇 - 水(3:0.1:2:3,v/v)组成的溶剂体系,以较低的有机相作为流动相,在800转/分钟的转速下进行。得到了72毫克纯度超过97%且回收率约为95%的刺桐碱。通过质谱(MS)和核磁共振(NMR)鉴定了其化学结构。
