[ Method ] Morphological traits of Brazilian ginseng root were observed with traditional methods. Then, the root, stem and [e',ff of Brazilian ginseng were sliced, and observed under a microscope. The physical and chemical properties of root extract were detected. [ Result] Brazilian ginseng root is elongated and cylindrical, with obvious longitudinal ridges and sparse root marks, some irregularly shaped lenticels on the sm'face. The cork layer of crosssection has five or more rows of cork cells. The abnormal vascular bundles are arranged in two to three rings. There are two to three central vascular bundles. The wood fibers it, powder are long, with one bifurcate end. The vessels have bordered pits. The sand crystals are scattered or in the parenchyma surrounding the fibers. The mucilage cells are oval and widely exist. Physical and chemical experiments showed that the rool of Brazilian ginseng eantains sterols or trilerpenes and saponins. [ Conclusion] The results will provide a theoretical basis for the pharmacological identificatian of Brazilian ginseng.展开更多
