摘要:

应用高速逆流色谱法分离制备花椒中的黄酮化合物。以氯仿-甲醇-正丁醇-水(4:3:0.5:2,V/V)为两相溶剂系统,在主机转速为850r/min、流速2mL/min、检测波长254nm条件下进行分离制备,共得到6个峰。采用高效液相色谱对所收集的峰进行纯度检测,对纯度较高的4种化合物(按照出峰次序标记为A、B、C、D)进行结构鉴定,A为茴香苷(foeniculin);B为槲皮素-7-葡萄糖苷(quercetin-7-glucoside);C为芦丁(rutin);D为槲皮素-3-半乳糖苷(quercetin-3-galactoside)。

Abstract:

Flavonoids from Zanthoxylum bungeanum were separated by high-speed countercurrent chromatography. The separation was performed using a two-phase solvent system composed of chloroform, methanol, n-butanol and water(4:3:0.5:2, V/V) at a flow rate of 2.0 mL/min, and rotation speed and detection wavelength were set at 850 r/min and 254 nm, respectively. Six flavonoids were detected by HPLC. The purities of peaks 1, 2, 3, 4, 5 and 6 were 72.7%, 67.8%, 89.6%,96.5%, 94.1% and 91.3%, respectively. Their structures were characterized as foeniculin, quercetin-7-glucoside, rutin and quercetin-3-galactoside by MS and 1H-NMR.
