沉香属的化学分类学研究

为探讨瑞香科沉香亚科的分类学地位,结合其他亚科植物的化学成分类型,对从沉香属植物分离到的各类化学成分进行了综述。从二萜和黄酮(烷)的成分类型判断,沉香亚科的进化地位低于瑞香亚科;从三萜成分类型来看,其地位又比Gonystyloideae亚科稍高;同时2-(2-苯乙基)色酮类和二苯基甲酮类成分为沉香属甚至沉香亚科的特征性成分。因此,沉香亚科是瑞香科中进化程度相对较低的类群,处于瑞香亚科和Gonystyloideae亚科之间。

Chemotaxonomy Studies on the Genus Aquilaria

In order to understand taxonomy position of Aquilarioideae, belonging to Thymelaeceae, the chemical constituents extracted from the genus Aquilaria was summarized, and the chemotaxonomy of subfamily Aquilarioideae was discussed by comparing the chemical constituents from other subfamilies in Thymelaeceae. It was regarded that the evolution status of subfamily Aquilarioideae was lower than that of subfamily Thymelaeoideae according to the types of diterpenoid and flavonoid, but higher than that of subfamily Gonystyloideae according to the type of triterpenoid. At the same time, 2-(2-phenylethyl) chromones and dibenzophenones were taken as the characteristic components of the genus Aquilaria, or even subfamily Aquilarioideae. Therefore, the status of subfamily Aquilarioideae was approved and regarded as the lower evolution group in Thymelaeceae, exiting between subfamily Thymelaeoideae and subfamily Gonystyloideae.
