| 摘 要： | 对黄檗主要药用成分小檗碱、掌叶防己碱和药根碱在成树、幼树中的分布和季节变化进行了系统的研究.结果表明:黄檗树干韧皮部中3种生物碱含量均随着树干位置增高而降低,成树在地面至 1.5 m 高度内随位置增高而急剧下降,超过 1.5 m 后趋于平稳,而幼树随位置增高近线性下降,幼树近地面 20 cm 茎段韧皮部中的小檗碱含量相当于成树;黄檗成树韧皮部中3种生物碱含量的季节变化不明显,而生长2年的黄檗幼树韧皮部中则有明显的季节变化,根是7月含量较高,茎是6月含量较高.

| Abstract: | Seasonal variation and distribution of principal medicinal constituents,namely berberine,palmatine and jatrorrhizine in mature trees and saplings of amur corktree(Phellodendron amurense Rupr.)were studied.In mature trees,alkaloids were decreased from base to the apex in the phloem,sharply dropped down at the height of 1.5 m from the base,then turned steady above the height of 1.5 m;whereas in saplings,alkaloids levels declined linearly with the increased height from the base.The alkaloids content at the height of 20 cm from the base was equivalent to that at the height of 1.5 m in mature tree.In contrast to an unobvious seasonal variation of alkaloids content in mature tree,alkaloids content in two-year saplings changed remarkably,the highest contents were showed in July in roots and in June in the stem. |
