Reversed-phase HPLC analyses of the methanol extract of the leaves of Erica arborea afforded a novel phenylpropanoid glucoside, named ericarborin, together with five flavonoids, dihydromyricetin 3-O-alpha-L-rhamnopyranoside, quercetin 3-O-beta-D-glucopyranoside, quercetin 3-O-alpha-L-rhamnopyranoside, apigenin 7-O-beta-D-glucopyranoside and apigenin 7-O-beta-D-(6-O-acetyl-glucopyranoside). While the structure of ericarborin was determined by extensive 1D and 2D NMR analyses, the structures of all known flavonoids were determined by direct comparison of their spectroscopic data with respective literature data. The antioxidant properties of these compounds were assessed by the DPPH assay. The chemotaxonomic significance of these phenolic compounds has been discussed.
对刺叶石楠叶甲醇提取物进行反相高效液相色谱分析，得到一种名为刺叶石楠苷的新型苯丙素苷，以及五种黄酮类化合物，即二氢杨梅素3 - O -α - L - 鼠李糖苷、槲皮素3 - O -β - D - 葡萄糖苷、槲皮素3 - O -α - L - 鼠李糖苷、芹菜素7 - O -β - D - 葡萄糖苷和芹菜素7 - O -β - D -（6 - O - 乙酰基 - 葡萄糖苷）。刺叶石楠苷的结构通过广泛的一维和二维核磁共振分析确定，所有已知黄酮类化合物的结构则通过将其光谱数据与相应文献数据直接比较来确定。这些化合物的抗氧化性能通过DPPH法进行评估。已讨论了这些酚类化合物的化学分类学意义。
