云南产菊科中草药及其水提液中铜钼含量特征分析

Analysis of the Characteristics of Cu and Mo Contend in Medicinal Compositae Plants and its Decoctions

对云南产17种菊科中草药及其水提液中铜钼元素含量进行测定,并分析其特征。结果显示在生药中铜钼含量的频数分布以及水提样中铜含量的频数分布为正态。铜钼比值,其中生药中艾叶的比值最大,水提液中香丝草的最大。生药中铜钼含量呈负相关,水提液中的铜钼含量呈正相关,但未达显著水平。

The characteristics of Cu and Mo in 17 kinds of medicinal plants compositae and its decoctions from Yunnan were analyzed.The results showed that frequency of Cu and Mo were both normal in crud drugs and decoctions.Cu/Mo ratios were all above 0,while in crude drugs Folium Artemisiae Argyi was the highest,in decoctions Conyza bonariensis（L.） Cronq.was the highest.Cu and Mo in crude drugs were negative correlation,while in decoctions Cu and Mo were positively correlated,but not significant.
