摘 要:用常温超高压技术提取山楂中黄酮类化合物,为了研究提取的最佳工艺,采用正交试验优化,利用分光光度法检测提取液中总黄酮含量。结果表明,超高压提取山楂果中黄酮类化合物的最佳提取工艺参数分别为:提取溶剂为50%乙醇,料液比为1:40,浸泡时间2h,提取压力300MPa,提取时间为3min。超高压提取时间短,提取液澄清稳定。The ultrahigh pressure extraction method was used to extract flavonoids from Hawthorn at normal temperature. The content of flavonoids was determined by UV - spectrophotometry. Parameters that may influence the extraction process were investigated. The orthogonal test was applied to obtain the optimum extraction condition, which was as follows : solvent of 50% ethanol, ratio of raw Hawthorn (g) to solvent (mL) of 1:40, marinate time of 2 hours, extraction pressure of 300mPa and extraction time of 3 min. Results of this work show that the ultrahigh pressure extraction method has several advantages, such as shorter extraction time, and less impurity in the extracted flavonoids.
