红花岩黄芪根在民间不仅作为一种草药入药,同时在我国某些地区还作为药典品种红芪的代用品入药。本文首先建立了红花岩黄芪根的高效液相色谱指纹图谱分析方法,并采用建立的方法对不同批次的红花岩黄芪根进行了化学指纹分析,确定了22个共有指纹峰,指认了其中8个特征指纹峰的化学结构。结果显示尽管不同产地红花岩黄芪根的化学指纹稍有差异,但主要成分基本一致?而红花岩黄芪根和红芪的化学指纹谱图则完全不同,因此至少从化学角度表明红花岩黄芪根不宜作为红芪代用品入药。
The root of Hedysarum multijugum(RHM) is recorded as a folk herbal medicine in China and is sometimes used as a substitute for Hedysari Radix, which is a famous traditional Chinese medicine derived from the roots of Hedysarum polybotrys. In the present study, a sensible, reliable, and reproducible HPLC-DAD fingerprint analysis method for RHM was developed and then subsequently applied to analyze RHM samples from different origins. The chemical constituents of the RHM samples were generally consistent, although it was slightly affected by the local environment of the plant. In addition, the chemical constituency of RHM was shown to be significantly different from that of Hedysari Radix, suggesting that RHM is not suitable as a substitute for Hedysari Radix, at least from the chemical point of view.
