摘要: 采用组织化学方法研究了六盘山鸡爪大黄根蒽醌类化合物的组织化学定位特征及贮藏和积累的规律。结果表明:蒽醌类化合物在根内的贮藏是多位点的,在根周皮的木栓层和栓内层、次生维管组织的维管射线和根中央的部分木薄壁细胞内不同程度地贮藏和积累了一定数量的蒽醌类化合物,次生木质部的木射线和次生韧皮部的韧皮射线是主要贮藏和积累的部位,早期形成的维管射线中蒽醌类化合物的含量较晚期形成的射线含量高。

Abstract: The characteristics of histochemical location and the storage and accumulation laws of anthraquinone compounds in root of Rheum tanguticum Maxim.et Balf. var. liupanshanense Cheng et kao were studied by histochemical methods.The results showed that the distribution of anthraquinone compounds in the root was of multilocus,anthraquinones of root exist in phellem and phelloderm of periderm and vascular rays of secondary vascular tissue and part of xylem parenchyma in the center of root differently,the xylem rays of secondary xylem and the phloem rays of secondary phloem in root are chief tissues which store and accumulate anthraquinones,anthraquinones content is higher in mature vascular ray cells than in immature vascular ray cells.

Key words: Rheum tanguticum Maxim.et Balf.var.liupanshanense Cheng et kao, root, anthraquinones, histochemistry location
