从胡颓子叶中分离得到7种新单宁，分别命名为elaeagnatins A-G和15种已知单宁及其相关多酚类化合物，其结构经波谱和化学方法鉴定为单体和二聚C-葡萄糖苷类化合物。胡萝卜素B、C和F是第一批以葡萄糖酸为核心的C-葡萄糖苷单体和单宁单体组成的二聚体。
Seven new tannins, elaeagnatins A-G, have been isolated from the leaves of Elaeagnus umbellata (Elaeagnaceae) together with fifteen known tannins and related polyphenols, and their structures have been characterized as monomeric and dimeric C-glucosidic ellagitannins on the basis of spectral and chemical evidence. Elaeagnatins B, C and F are the first dimers composed of C-glucosidic monomer and ellagitannin monomer with a gluconic acid core.
