摘要: 通过正交试验,对超临界CO2流体提取杜仲叶总黄酮的工艺进行了优化。实验结果表明最佳提取工艺条件为:夹带剂用量4.5ml/g,提取压力28MPa,提取时间2.5h,提取温度35℃。采用液质联用技术分析提取物,发现其主要成分可能为氯原酸、芦丁、金丝桃苷、紫云英苷、槲皮素-3-O-葡萄糖基-(1→2)-阿拉伯糖苷或槲皮素-3-O-木糖基-(1→2)-葡萄糖苷等。

Abstract: The CO2 supercritical fluid extraction technology of flavonoids in Evcommia vlmoides Oliv. leaves was optimizedby orthogonal test. The experimental results showed that the optimal parameters were 4.5 ml/(g materials) ethanol dosage, 28 MPa pressure, 35 ℃ temperature and 2.5 h time. It was determined by LC-MS chromatograms that the main possible components in the Evcommia vlmoides Oliv. leaves extract were chlorogenic acid and several flavonoids such as lutin, hyperoside, astragalin and luteolin-3-O-disaccharide.

Key words: flavonoids of Evcommia ulmoides Oliv. leaves, supercritical CO2 extraction, LC-MS
