摘要: 采用高速逆流色谱从川西獐牙菜中分离制备了两种高纯度苷类化合物。以正丁醇:氯仿:甲醇:水(3.4:8:5:6, v/v)为溶剂系统,主机转速为800 r/min,流速:0-210 min,1.5 mL/min;210-360 min,2.5 mL/min,检测波长254 nm的条件下进行分离制备,在360 min内从100 mg样品中一步分离制备得到1-O-樱草糖-3,7,8-三甲氧基口山酮(I,11 mg)和异荭草苷(II,24 mg)。经HPLC检测,两个化合物的纯度均在99%以上,结构由UV、1H-和13C-NMR鉴定。

Abstract: A high performance method for isolation and purification of two glycosides from Swertia mussotti was successfully established by utilizing high-speed counter-current chromatography (HSCCC). Separation was performed with a two-phase solvent system composed of n-butanol-chloroform-methanol-water (3.4:8:5:6, v/v). 1-O-primeverosyl-3,7,8-trimethoxyxanthone (11 mg) and isoorientin (24 mg) were isolated and purified in one-step elution from 100 mg crude sample under the conditions of a flow rate 1.5 mL/min in the initial 210 min followed by 2.5 mL/min, 800 r/min and the detection wavelength of 254 nm. HPLC analysis showed that the purity of two compounds was over 99%. Their chemical structures were confirmed by UV, 1H- and 13C-NMR.

Key words: Swertia mussotti, HSCCC, 1-O-primever-osyl-3, 7, 8-trimethoxyxanthone, isoorientin
