射干及其鸢尾属代用品中芒果苷的定量-分析

以活性成分芒果苷（ｍａｎｇｉｆｅｒｉｎ）作为质控指标，用ＲＰ－ＨＰＬＣ法对７个野生或栽培的射干、１个射干的茎叶和３个射干的代用品，共１１个样品进行了分析。结果说明：射干中的芒果含量明显高于其代用品：川射干（鸢尾Ｉｒｉｓ ｔｅｃｔｒｎｕｍ）和白射干（野鸢尾Ｉ．ｄｉｃｈｏｔｏｍａ）。不同产地的射干也有一定的含量差异（Ｐ〈０．０５）。本法快速简便，测定数据可作为射干质量控制和品质评价的可靠依据。

Quantitative Determination of Mangiferin in Rhizoma Belamcandae and Its Substitute of Iris L.

Mangiferin, one of the active constituents of Rhizoma Belamcandae, in samples of Belamcanda chinensis (L.) DC or its substitute was determined quantitatively by RP HPLC The 11 samples collected from different localities for analysis were: 7 rhizomes of wildly grown or cultivated B chinensis, 1 of its leaf and stem, and 3 substitutes (a wildly grown and another commercially available Iris tectorum Maxim and a I dichotoma Pall ) Results of the analysis showed that the contents of mangiferin in Rhizoma Belamcandae were significantly higher than that of its substitutes I tectorum and I dichotoma There were also certain significant differences between samples from different localities (P<0 05), but with no statistically significant difference between the rhizome or leaf and stem, neither between cultivated and wildly grown samples, (P>0 05) The method was proved to be quick, simple and reproducible, and may provide a reliable basis for the quality control and evaluation of B chinensis
