4种鼠尾草属植物根、茎、叶中脂溶性成分的分布差异性

为了说明4种鼠尾草属植物脂溶性成分在根、茎、叶中的分布情况,本文采用了组织化学定位和HPLC图谱分析相结合的方法,对4种鼠尾草属植物不同部位的脂溶性成分进行了分析.结果表明:4种鼠尾草属植物的根、茎、叶中脂溶性成分的分布有差异,根中脂溶性成分分布于周皮,茎、叶中脂溶性成分分布于表皮.丹参和白花丹参根中的脂溶性成分主要是丹参酮ⅡA、丹参酮Ⅰ和二氢丹参酮Ⅰ,鼠尾草和药用鼠尾草根中仅含丹参酮ⅡA,不含丹参酮Ⅰ和二氢丹参酮Ⅰ.茎、叶中的脂溶性成分不是丹参酮ⅡA、丹参酮Ⅰ和二氢丹参酮Ⅰ.脂溶性成分的种类和含量随品种和引种地的不同而产生差异.这一结果明确了脂溶性成分在4种鼠尾草属植物不同部位的确切分布,为准确用药提供了依据.

DISTRIBUTIONAL DIFFERENCE OF FAT-SOLUBLE COMPOUNDS IN THE ROOTS, STEMS AND LEAVES OF FOUR SALVIA PLANTS

To illustrate distribution of fat-soluble compounds in the roots, stems and leaves of four Salvia plants, the methods of Histochemistry and HPLC were adopted to analyze different parts of the four Salvia plants in this paper. The results showed that distribution was differential, and following as this: the roots, stems and leaves of four Salvia plants contained fat-soluble compounds, moreover, the fat-soluble compounds of the roots located in periderm and the stems and leaves in epidermis. The main components of the fat-soluble compounds were Tanshinone IIA, Tanshinone I and Dihydrotanshinone I in the toots of Salvia miltiorrhiza Bunge and Salvia miltiorrhiza bge. f. alba, yet there were only Tanshinone IIA in the roots of Salvia japonica and Salvia officinalis. And fat-soluble compounds were not Tanshinone IIA, Tanshinone I and Dihydrotanshinone I in the stems and leaves of four Salvia plants. The type and content of fat-soluble compounds related to the species and introduction regions, they changed with the species and introduction regions. The conclusion clarified the accurate distribution of fat-soluble compounds in the different parts of four Salvia plants, and provided some theoretical basis for the application of Chinese herbs.
