摘　　要：研究了高压均质提取山楂叶中有效成分的最佳工艺,通过将高压均质提取法与热回流提取、超声提取法进行比较,总黄酮提取率比为8.39∶7.76∶7.33,得出高压均质提取山楂叶的最佳提取工艺条件为:体积分数70%的乙醇为溶剂,压力60 MPa,山楂叶与溶剂质量之比为1∶30,提取时间30 min,总黄酮的提取率达8.39%。To obtain the main functional components from hawthorn leaves by high-pressure homogenization extraction （HPHE）, the optimum process conditions are 70% （V/V） ethanol as solvent, extraction pressure 60 MPa, material/solvent （w/w） ratio 1/30 and extraction time 30 min. Yield of flavonoids is up to 8.39%. By contrast, the yields of flavonoids by heat reflux extraction method and ultrasound extraction method are 7.76 and 7.33 % respectively.
