摘要: 为了高效分离得到高纯度的穿心莲活性成分,应用高速逆流色谱(HSCCC),在流速为2.0mL/min的正己烷、乙酸乙酯、乙醇和水(体积比为1∶4∶2.3∶2.7)的两相溶剂系统中,从穿心莲的粗提物中同时分离纯化出4种生物活性化合物.利用理化常数、质谱(MS)、核磁共振(1 HNMR、13 CNMR)等波谱检测技术对其化学结构进行鉴定,发现此4种化合物分别为14-脱氧穿心莲内酯-19-β-D-葡萄糖苷(Ⅰ)、新穿心莲内酯(Ⅱ)、穿心莲内酯(Ⅲ)和14-脱氧穿心莲内酯(Ⅳ).从500 mg粗提物中分离得到4种化合物的量分别是56.8、1.5、108.3和218.0 mg;纯度分别达98.5%、92.5%、96.2%和93.6%;回收率分别为95.5%、97.8%、93.2%和91.9%.说明高速逆流色谱是有效的,可分离得到高纯度产物.

Abstract:

In order to efficiently separate high-purity active components from Andrographis paniculata, a high-speed counter-current chromatography (HSCCC) procedure was developed for the preparative separation and purification of four bioactive compounds from the crude extract of the plant in a simultaneous process. The procedure was performed in a two-phase solvent system of n-hexane-ethyl acetate-ethanol-water ( in a volume ratio of 1 : 4:2.3 : 2.7 ) at a flowrate of 2.0 mL/min. By determining the physicochemical properties and according to the results of MS, 1 HNMR and 13 CNMR, the four separated compounds were identified as 14-deoxy-andrographolide-19-β-D-glucosides ( Ⅰ ), neoandrographolide ( Ⅱ ), andrographolide ( Ⅲ ) and 14-deoxy-andrographolide ( Ⅳ ). Moreover, 56. 8, 1.5, 108.3 and 218.0 mg of compounds Ⅰ - Ⅳ were respectively prepared from 500mg of crude extract by the proposed procedure, with the purities of 98.5% , 92.5% , 96.2% and 93.6% and the recoveries of 95.5% , 97.8%, 93.2% and 91.9%, respectively.
