摘 要 ：设置光强分别为全光照的100%（不遮荫）、75%、50%和25%的4种光照处理，比较了不同光强下1年生黄檗幼苗主要药用成分小檗碱、药根碱和掌叶防己碱含量的变化。结果表明，全光照有利于小檗碱、药根碱和掌叶防己碱在茎外皮和根中的合成和积累，总体上随光强减弱，3种生物碱含量降低。相对光强为75%时黄檗幼苗生物量最大，而75%相对光强下黄檗幼苗3种生物碱的单株产量（生物碱含量与生物量之积）最高。

Abstract:Amur corktree (Phellodendron amurense), a rare tree species in China, is also a medicinal plant containing berberine, jatrorrhizine and palmatine as its main effective ingredients. In order to examine the impact of light intensity on the contents of the three main effective alkaloidals in this plant, we designed different light intensity (100%, 75%, 50% and 25% of full sunlight) to treat the seedlings and determined their contents of berberine, jatrorrhizine, and palmatine. The results showed that full-sunlight treatment was the highest in the three alkaloids content compared with the other weaker light-intensity treatments, while the 75% full-sunlight treatment was highest in biomass production. Therefore the 75% full-sunlight treatment is recommended in terms of the production of the three alkaloids, because it is the highest if we consider biomass and alkaloids contents simultaneously.
