摘要
杜仲(EucommiaulmoidesOliv.)是我国所特有的经济植物。传统以树皮入药,近年来研究表明,杜仲叶与皮的化学成分基本相同,药效类似[1~4]。杜仲叶、皮中主含环烯醚萜甙类、黄酮类及酚酸类成分。研究不同地理种源和不同季节杜仲叶片绿原酸和总...
The contents of chlorogenic acid and total flavonoid of Eucommia ulmoides Oliv. spring leaves and autumn leaves of 17 provenances were determined by HPLC and UV spectrophotometer. The chlorogenic acid and total flavonoid contents of spring leaves is 2.31%~4.59% and 0.83%~2.69% respectively. The chlorogenic acid and total flavonoid contents of autumn leaves is 0.25%~2.02% and 0.95%~2.01% respectively. As the content of chlorogenic acid of spring leaves is much higher than that of autumn leaves, the no distinctive different content of total flavonoid is in spring and autumn leaves.
