undescribed compounds (1–6) were isolated from the leaves of Viburnum erosum along with four known compounds 7–10. The structures were determined by NMR and MS spectroscopic analyses, and their absolute configurations were established by chemical and spectroscopic methods. Compounds 1–6 were α-glucosidic hydroquinone derivatives with different linear monoterpenoid structures. Compounds 1–10 were also evaluated
从荚Vi的叶片中分离出六个未描述的化合物(1-6)和四个已知化合物7-10。通过NMR和MS光谱分析确定结构,并通过化学和光谱方法确定它们的绝对构型。化合物1 - 6分别为α糖苷氢醌衍生物具有不同的线性单萜结构。化合物1-10还评价它们的酪氨酸酶抑制活性,和10显示出酪氨酸酶的有效抑制与IC 50的值37.9 μ中号相比47.6 μ阳性对照的M(β-熊果苷)。
