山竹果皮中总黄酮的提取研究

Study on Extraction of Total Flavonoids from Mangosteen Peel

本试验以山竹果皮为研究对象,以乙醇为提取溶剂,提取山竹果皮中的黄酮类物质;采用正交试验优化山竹果皮总黄酮的醇提法提取工艺,确定最优的工艺条件为乙醇浓度50%、料液比1∶90(g∶mL)、提取温度60℃、提取时间20 min,在最优工艺条件下,山竹果皮的总黄酮提取率达9.05%。

This experiment takes the mangosteen peel as the research object and uses ethanol as the extraction solvent to extract flavonoids from the mangosteen peel;orthogonal experiments were used to optimize the alcohol extraction process of total flavonoids from mangosteen peel.The optimal process conditions were determined to be ethanol concentration of 50%,solid-liquid ratio of 1∶90(g∶mL),extraction temperature of 60℃,and extraction time of 20 minutes.Under the optimal process conditions,the extraction rate of total flavonoids from mangosteen peel reached 9.05%.
