| Using Cistanche deserticola as the material, this paper studied contents and differences of the total flavonoids, polysaccharides, soluble proteins, trace elements (copper, iron, manganese, zinc), echinacoside and verbascoside in different regions of the Gurbantünggüt Desert. The purpose of this study was to provide a basis for the evaluation and selection of fine varieties which are suitable for the growth of Gurbantünggüt Desert with high content of medicinal substances. The results showed that the content of the efficacy of C. deserticola was up to 18.21% in the Fangcao Lake area. Followed by 18.18% in Tacheng area; The content of total flavonoids was the highest active ingredient in C. deserticola with an average 6.868%, next was echinacoside with 2.718%. The efficacy of C. deserticola was the highest in the fleshy stem (lower) and lower in the upper and middle parts. The effective content of C. deserticola was in the order of Fangcao Lake ＞Tacheng ＞Qitai ＞Jimsar ＞Bole ＞Altay in different regions of the Gurbantünggüt Desert by comprehensive evaluation. These results indicated that there were some differences in the active ingredients of C. deserticola in different regions of Gurbantünggüt Desert, the contents of effective substances of C. deserticola were the highest in Fangcao Lake and Tacheng area. The content of effective substances in the fleshy stem was much higher than that in upper and middle stem, indicating that the lower fleshy stem had better efficacy and the prospect of development and utilization. |
