利用超高压技术提取补骨脂中补骨脂素和异补骨脂素
Application of Ultra High Pressure Technology in Extraction of Psoralen and Isopsoralen from Fructus Psoraleae
摘要
Abstract
Fructus Psoraleae is one of the most popular raw materials for health products in China.The major bioactive components of Fructus Psoraleae are psoralen and isopsoralen.In the present work,ultra high pressure extraction（UHPE） was used to extract psoralen and isopsoralen from Fructus Psoraleae and compared with the reflux extraction.We found that UHPE resulted in higher yields of psoralen and isopsoralen than the refulx extraction.Using a uniform design,the optimum UHPE conditions including pressure,ethanol concentration,liquid-to-solid raio（mL/g） and extraction time were determined to be 100 MPa,53%,90：1 and 3 min for psoralen and 100 MPa,55%,90：1 and 3 min for isopsoralen,respectively.UHPE proved to enable normal temperature and rapid extraction of psoralen and isopsoralen,thereby providing an efficient production approach for applying psoralen and isopsoralen in health products and functional products.关键词
