常温超高压提取人参总皂苷

High pressure extraction of total ginsenoside at room temperature

在常温条件下使用超高压提取了人参皂苷; 采用均匀设计法对提取工艺条件作了优化; 常温超高压提取人参皂苷最优工艺条件为: 溶剂50%乙醇、压力200 MPa、固(g) 液(ml) 比1∶100、提取时间1 min; 提取收率为7 32%. 与煎煮法、回流提取法、超声提取法、超临界CO2 提取等方法做了比较, 结果表明常温超高压提取具有提取温度低(常温)、提取时间短、提取得率高、能耗低、绿色环保等优点, 为人参皂苷的提取提供了一种新技术、新工艺.

A new extraction process, named high pressure extraction (HPE) at room temperature, was used to extract ginsenoside from ginseng. The extraction process of HPE was optimized with the uniform test design method. The optimum HPE process conditions of ginsenoside were: solvent 50% ethanol, pressure 200 MPa, ratio of raw ginseng (g) to solvent (ml) 1:100, extraction time 1 min, yield 7.32%. Compared with the cooking, reflux extraction, ultrasonic and supercritical CO2 extraction processes, HPE have many advantages, such as higher yield, no heating, shorter extracting time and energy saving. HPE provides a new process for the extraction of ginsenoside from ginseng at room temperature.
