Pharmacognosy of Brazilian Ginseng ( Pfaffia paniculata)

[ Objective ] This study aimed to explore the pharmacognostical features of Brazilian ginseng （ Pfaffia paniculata）, anti to provide a theoretical basis ior its development and utilization. [ 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.

外来资源巴西人参的研究进展

巴西人参主要分布于热带雨林地区,具有极高的保健及药用价值,其根部作为药物使用已有300多年的历史,在巴西一带被称为“Para Tudo”,对疲劳、免疫力低下等亚健康具有良好的防治作用。因具有较好的研究与商业价值,作为一带一路引进的重要药用新资源,巴西人参越来越受到关注。为进一步对巴西人参的研究与产品开发,现就国内外巴西人参种植分布情况、发展应用现状、化学成分、药效及安全性研究等进行评述,以期为巴西人参的开发研究提供参考,也为丰富中药资源、带动引种地经济发展、助力健康中国贡献力量。

新外来中药巴西人参(珐菲亚)的药性探讨

巴西人参Hebanthe eriantha(Poir)Pedersen是中南美洲地区一种应用广泛的药用植物。本文查阅国内外相关研究文献及资料,在中医药理论的指导下,探究巴西人参的中药药性。巴西人参性微温,味甘、微苦;归肾、脾、肝经。功效为补肾助阳,益气健脾,养血疏肝。可用于肾虚阳痿,精血不足,性欲淡漠,阳痿早泄;脾气虚弱,神疲乏力;血虚不寐;肝气郁结;癌病。药用部位为根及根茎,日用量为1~3 g,研粉冲服。概括归纳巴西人参的性味归经、功效主治及用法用量,以期为巴西人参在中医临床应用奠定理论基础,促进新外来中药的研究应用。

巴西人参化学成分和药理活性研究进展

巴西人参原产于南美洲,当地人把它当做具有壮阳、增强体质等作用的草药。巴西人参已在我国广西、浙江等地引种栽培成功,现代研究发现,其主要含有三萜和三萜皂苷类、甾体类等多种化学成分,具有抗肿瘤、抗炎、保护胃黏膜等药理活性。本文通过对近年来巴西人参的研究情况进行综述,阐明已有的化学物质基础和药理作用,为其进一步的深入研究和开发提供理论依据。
