摘　　要：比较不同工艺提取富集的老鹰茶中总黄酮含量,分别采用传统乙醇提取-正丁醇萃取法和水提取-大孔树脂法提取老鹰茶总黄酮,并用紫外分光光度法,以芦丁为标准品,270nm下测定总黄酮含量。水提取-大孔树脂法富集所得固体中黄酮含量较高,可达55.86%,回收率为105.6%,RSD=1.64%。水提取-大孔树脂富集的工艺操作简单,所得固体黄酮含量高,更适于老鹰茶总黄酮的提取,对进一步的工业化生产开发有较好的参考价值。To compare different extraction methods for the total flavonoids of Litsea coreana leaf, the contents of the total fla- vonoids of Litsea coreana leaf are determined by using the methods of traditional ethanol-n-butanol extraction and water-macro- porous resin extraction, and UV spectrophotometer. The content of the total flavonoids in the water-macroporous resin extraction is higher, up to 55.86 % , and the recycling rate is 105.6 % , RSD = 1.64 %. The method of water-macroporous resin extraction is simple, with the high total flavonoids content. This method is more suitable for extracting the total flavonoids of Litsea coreana leaf, and is useful to the further development in industrial production.
