黄酮类化合物具有较强的生理和药理活性.本实验首次从槭叶草中提取了其有效成分-黄酮类化合物,并分别采用柱层析和重结晶法分离出纯品.所得结果表明：产品的产率在 3%～ 5%之间,色泽呈黄棕色,颗粒状结晶,其水溶性较差,但醇溶性较好,其颜色反应呈阳性.经薄层法鉴定, Rf值在 0.7左右；确为黄酮类化合物. Flavonoids have strong physiological and pharmacological activities. For the first time, the effective components of flavonoids were extracted from the leaves of the grass, and the pure products were separated by column chromatography and recrystallization, respectively. The results showed that: The yield is between 3% and 5%, the color is yellow-brown, granular crystal, its water-solubility is poor, but alcohol solubility is good, its color reaction is positive. After thin layer identification, Rf value is about 0.7 It is flavonoids.
