Abstract

A new compound, 3--(4--methyl-β-D-glucopyranosyl) xanthone () was isolated from the culture of NBRC106950. The structure of was mainly determined by H, C, 2D-NMR and HREIMS spectral analyses. The absolute configuration of 4--methylglucopyranosyl moiety was determined by the optical rotation of aqueous layer of hydrolyzed as D-configuration.

摘要

一种新的化合物，3--(4--甲基-β-D-吡喃葡萄糖基)呫吨酮（），从 NBRC106950 的培养物中分离得到。的结构主要通过 H、C、2D-NMR 和 HREIMS 光谱分析来确定。通过水解得到的水溶液层的旋光确定了 4--甲基吡喃葡萄糖基部分的绝对构型为 D-构型。
