Eight phenolic compounds, including two catechins (1 and 2), two proanthocyanidins (3 and 4), three lignans (5–7), and one phenol (8), were isolated from roots of Vaccinium dunalianum Wight (Ericaceae), together with two triterpenes (9 and 10). All of them were isolated from the title plant for the first time. Their chemical structures were established based on the extensive MS and NMR spectroscopic analysis. Compounds 6–10 acquired initially from the genus Vaccinium, showed some significances in chemotaxonomy.

越橘根中的酚类化合物和三萜类化合物及其化学分类学意义

八种酚类化合物，其中包括两个儿茶素（1和2），两个原花青素（3和4），三个木酚素（5 - 7），和一个酚（8），从根分离越桔dunalianum怀特（杜鹃花科），连同两个三萜（9和10）。所有这些都是首次从标题植物中分离出来。它们的化学结构是根据广泛的MS和NMR光谱分析建立的。化合物6 - 10从该属获得的最初越桔，在化学分类学中显示了一些意义。
