种中文名：红河鹅掌柴
种拉丁名：Schefflera hoi (Dunn) Vig.
中国植物志：54:034
种别名 ：
地理分布：分布于云南、四川、西藏。
毒 性：小鼠腹腔注射皮、叶的氯仿提取物600mg／kg，出现四肢无力、伏地，部分死亡[A-25]。
属中文名：鹅掌柴属
属拉丁名：Schefflera
科中文名：五加科
科拉丁名：Araliaceae
本科概述：本科约80属900多种，广布于热带至温带地区。我国有22属160余种，除新疆外，分布几遍全国，主产西南。本科有毒植物较少，仅常春藤、广东榴木和袍木有小毒。主要有毒成分是皂甙。本科植物人参(PanaxginsengC．A．Mey)、三七[P．Notoginseng(Burk．)P．H．Chen]是名贵药材，五加皮(细柱五加AcanthopanaxgracilistylusW．W．Smith的根皮)、通草(通脱木Tetrapanaxpapyriferus(Hook．)K．Koch的茎髓)是常用中药。近年对五加属植物刺五加(A．Senticosus(Rupr.etMaxim．)Harms)研究较多，并已广泛应用于临床。洋常春藤(HederahelixL．)为欧洲常见观赏植物，浆果可引起儿童中毒，症状有麻醉、腹泻、呕吐、昏迷、呼吸困难等。叶、果和种子含主要有毒成分为三萜皂甙常春藤皂甙(α，β—hederin)和常春藤皂甙A，B，C(hederasaponinA，B，C)，甙元为常春藤皂甙元(hederagenin)(9—5)或齐墩果酸(oleanolicacid)[1-4]。大鼠静脉注射常春藤甙LD50为13mg／kg，口服大于100mg／kg[5]。
