摘要
利用半薄切片技术、ICP-OES和HPLC研究梭梭和白梭梭的根结构、根系中矿质元素与次生代谢产物含量,结果表明,梭梭和白梭梭根基本结构相同,均由表皮、皮层及维管柱组成,具异常维管组织,皮层薄壁细胞在根中比例较大;梭梭和白梭梭根系中Na和K元素含量较高;根系次生代谢产物中蒽醌、生物碱类物质的含量较高。
The structure, mineral elements and secondary metabolites in roots of Haloxylon ammodendron and H. persicum were studied with semi-thin section, inductively coupled plasma optical emission spectrometry (ICP-OES) and high performance liquid chromatography (HPLC). The results showed that H. ammodendron and H. persicum had the same root structures on the whole, including epidermis, cortex and vascular cylinder. The roots contained abnormal vascular tissue, a large percentage of parenchyma cells, and high contents of sodium (Na) and potassium (K). In addition, high levels of anthraquinone and aconitum alkaloids were observed in the secondary metabolites of roots.
