摘要
为了进一步开发和利用我地区丰富的蒙药材资源,研究了栀子中总黄酮的提取条件,以亚硝酸钠—硝酸铝—氢氧化钠为体系,用分光光度法测定总黄酮的含量.结果表明,超声提取的最佳条件是使用70%乙醇、超声提取二次、超声时间30min;总黄酮的含量为3.5mg.g-1,样品的回收率在96.0%~101.7%.此结果为栀子药效功能的进一步研究、资源开发和利用提供了科学的依据.
In order to further develop and use my region's rich have medicinal materials resources, Zhizi the flavonoids extraction condition, the Jiangxi melia japonica son super living after extraction, and sodium nitrate-aluminum-sodium hydroxide to nitric acid system, with spectrophotometry the content of flavonoids. The results show that the optimum condition of the ultrasonic extraction for is to use 70% ethanol, ultrasonic extraction, ultrasonic time a 30 rain; The fla- vonoids content is 3.5 mg.g-1, recovery of samples in 96.0% - 101.7%. The results for Gardenia jasminoidesEllis, ja- ponica son efficacy function of further research, resource development and use nf the provided the science basis.
