  名称：

  Two new glycosides from Duboscia macrocarpa Bocq.

  摘要：

  Two new compounds namely dubosciasides A (1) and B (2) were isolated from stem bark of Duboscia macrocarpa Bocq. together with three known flavonoids. Their structures were determined by spectroscopic methods including one-and two-dimensional NMR, EIMS and HRESIMS. The new compounds were identified as 6-C-beta-D-apiofuranosyl-(1 -> 4)-beta-D-galactopyranosylnaringetol (1) and 1-O-alpha-L-rhamnopyranosyl-(1 -> 4)-beta-D-xylopyranosyl-3,4,5-trimethoxyphenol (2).
