刺五加[Acanthopanax senticosus(Rupr.etMaxim)Harms]系五加科植物,其根及根茎作为中药广泛使用,关于其根及根茎的化学与生物活性研究报道较多。关于刺五加叶中皂甙的含量及含量测定方法尚未见报道。本文根据三萜皂甙与香草醛—浓硫酸反应显色的原理,用比色法测定了刺五加叶中皂甙的含量。
Acanthopanax senticosus (Rupr.et Maxim) Harms] is an Araliaceae plant. Its roots and rhizomes are widely used as traditional Chinese medicines. There are many reports on the chemical and biological activities of its roots and rhizomes. There has been no report on the content and content determination of saponin in leaves of Acanthopanax senticosus. In this paper, according to the principle of coloration of triterpene saponins and vanillin-concentrated sulfuric acid, the content of saponin in leaves of Acanthopanax senticosus was determined by colorimetric method.
