昆明6种唇形科中草药铜锌含量特征分析

Analysis on Content of Cu and Zn in 6 Kinds of Medicinal Labiatae Plants from Kunming

对昆明 6种唇形科中草药铜锌含量特征进行了分析。结果表明 ,生药和水提物中铜锌含量的频数呈现正态分布 ,相互间呈正相关 ,但生药铜锌含量与相应的提取率却呈现负相关。生药中锌铜比值约大于 1,水提物中除匍匐风轮菜外 。

The characteristics on the content of Cu ane Zn in 6 kinds of medicinal Labiatae plants from Kunming were analysed.The results showed that frequency distributions of Cu and Zn content in crude and extracted drugs were normal.The positive correlation was shown.In crude drugs Zn/Cu ratios were above 1,while Zn/Cu ratio increased except that in Clinopodium repens among the extractions.
