Abstract:

The species of the genus Isodon from Lamiaceae are often rich in diterpenoids with high medicinal value. According to its frame and oxidation level, the chemodiversity of diterpenoid compounds in genus Isodon was investigated in present study. UPGMA analysis showed that Isodon can be divided into two groups: one is the species producing diterpenoids with two or three ring skeletons, the other is producing diterpenoids with four ring skeleton. When the compounds were mapped on the molecular phylogenetic tree, we found that the species producing three cyclic diterpenoids are much older, such as I.lophanthoides and I.lophanthoides var. micranthus, while those producing four cyclic diterpenoids are younger, such as I.adenanthus and I.xerophilus. These results will contribute to finding and exploiting the active ingredients of dierpenoids from the genus Isodon.

摘要：

香茶菜属（Isodon）由于富含二萜类化合物（Diterpenoids）而具有较高的药用价值，本研究根据其所含二萜的骨架和氧化状态，对该类化合物在香茶菜属植物中的分布规律进行研究。UPGMA聚类分析结果显示：含二环和三环二萜为主的植物种类聚在一支上，含四环二萜为主的植物种类聚在另一支上。进一步将二萜分为二环、三环、四环三大类绘制到分子系统树上结果显示：三环二萜主要分布在较原始的类群中，如：线纹香茶菜（I.lophanthoides）和小花线纹香茶菜（I.lophanthoides var. micranthus）；而四环二萜主要分布在较进化的类群中，如：旱生香茶菜（I.xerophilus）和腺花香茶菜（I.adenanthus）。本研究通过对二萜类化合物与香茶菜属系统发育之间存在的联系进行探讨，有助于对香茶菜属植物中的二萜类化合物活性成分进行筛选与研发。
