| 摘 要： | 用φ=5%的香草醛-冰醋酸、高氯酸显色,以熊果酸纯品为对照,在波长548nm处用分光光度法测定了6种冬青科苦丁茶功能叶和4种市售苦丁茶冬青嫩芽产品中的总三萜含量。结果显示:大叶冬青功能叶中的总三萜类物质含量最高,市售苦丁茶冬青的嫩芽产品中其总三萜类物质含量最低。6种供试的冬青科苦丁茶样品中总三萜类物质的质量分数依次排序为:大叶冬青(4.209%)枸骨(3.866%)霍山冬青(3.064%)华中枸骨(2.775%)苦丁茶冬青(2.74%)五棱冬青(2.648%)。

| Abstract: | 5% vanillin acetum and perchloric acid were used as the color developer,and the pure ursolic acid was used as the reference,the contents of total triterpenoid in adult leaves of 6 Kudingcha species in Aquifoliaceae and 4 kind marketed shoots products of Ilex kudingcha C. J. Tseng were determined by spectrophotometry at 548 nm. The results showed that the adult leaves of I. latifolia Thunb. had the highest total triterpenoid,and the marketed shoots products of I. kudingcha C. J. Tseng had the lowest total tr... |
