A new coumarin glucoside named daphneside was isolated along with two known coumarin glucosides, daphnin and daphnetin-8-glucoside, and two known phenylpropanoid glucosides, syringin and syringinoside, from a water-soluble fraction of Daphne arisanensis HAYATA (Thymelaeaceae) collected in Taiwan. The structure of daphneside was elucidated by spectroscopic and chemical methods.
从台湾采集的 Daphne arisanensis HAYATA(百日草科)的水溶性馏分中分离出了一种名为 daphneside 的新香豆素葡萄糖苷,以及两种已知的香豆素葡萄糖苷(daphnin 和 daphnetin-8-葡萄糖苷)和两种已知的苯丙酮葡萄糖苷(syringin 和 syringinoside)。通过光谱和化学方法阐明了 Daphneside 的结构。
