采用薄层扫描法测定黄藤根和茎中巴马汀(Palmatine)与药根碱(Jatrorrhizine)的含量。结臬巴马汀含量根较茎高;药根碱茎中高,而根中仅痕量。
The content of palmatine and jatrorrhizine in roots and stems of Scutellaria batatas was determined by TLC scanning. The content of carotenoids was higher than that of stems; the roots of the medicines were high in the stems and only trace amounts were found in the roots.
