A new arbutin derivative, namely dunalianosides J (1), along with six known compounds, arbutin (2), robustaside A (3), 6'-O-caffeoylarbutin (4), dunalianoside D (5), kaempferol 3-O-β-D-glucopyranoside (6) and kaempferol 3-O-β-D-sambubioside (7) were isolated from the leaves of Vaccinium dunalianum Wight (Ericaceae). The structure of 1 was elucidated by extensive 1D and 2D NMR, HR-MS and CD spectroscopic analyses. In which, kaempferol 3-O-β-D-sambubioside (7) was isolated from the genus Vaccinium for the first time.
从越桔科植物灯笼草（Vaccinium dunalianum Wight）的叶子中分离得到一种新的熊果苷衍生物，即灯笼草苷J（1），以及六种已知化合物，熊果苷（2）、粗壮苷A（3）、6'-O-咖啡酰熊果苷（4）、灯笼草苷D（5）、山柰酚3-O-β-D-葡萄糖苷（6）和山柰酚3-O-β-D-接骨木二糖苷（7）。通过广泛的一维和二维核磁共振、高分辨质谱和圆二色光谱分析确定了1的结构。其中，山柰酚3-O-β-D-接骨木二糖苷（7）首次从越桔属植物中分离得到。
