虎眼万年青各组织部位中皂苷的分布

Distribution of caudaside in different tissues of Ornithogalum caudatum Ait

将虎眼万年青茎、须、叶三部位的皂苷提取液脱糖和脱色后,检测其皂苷的组成和含量差异。结果表明,各组织部位皂苷得率分别为:茎中0.98%,叶中0.71%,须中0.43%。TLC检测结果茎中斑点数约为10,叶中约为9,须中约为7。HPLC检测结果为:茎中皂苷总数约为32种,叶中约为29种,须中约为25种。且就所选的4种组分开看,其在不同部位中的含量也不同:组分1在须中含量最高,组分2和组分4在茎中含量最高,组分3在叶中含量最高。

The distribution of caudaside in Ornithogalurn caudaturn Ait was assessed. The extract yield in root ball is 0.98 %, in the stem 0.71%, in the root 0.43 %. The spots＇ on TLC of root ball are 10, stem 9, root 7. There are 32 HPLC peaks in the root ball, 29 peaks in the stem and 25 peaks in the root. Moreover, the same caudaside＇s content in different part is different. Caudaside 1 is high in the root, caudaside 2 and caudaside 4 are high in the root ball, caudaside 3 is high in the stem.
