A new highly oxygenated iridoid glucoside, urphoside B (1) was isolated from the Veronica pectinata var. glandulosa together with seven known iridoid glucosides, aucubin, catalpol, veronicoside, catalposide, verproside, amphicoside and 6-O-veratroyl catalpol. The planar as well as the stereo structures of the isolated compounds were determined by means of extensive 1D- and 2D-NMR spectroscopy and confirmed by HR-Mass.
从腺毛婆婆纳中分离出一种新的高度氧化的环烯醚萜苷,urphoside B(1),同时还分离出七种已知的环烯醚萜苷,桃叶珊瑚苷、梓醇、婆婆纳苷、梓苷、婆婆纳新苷、双角苷和6-O-藜芦酰梓醇。通过广泛的一维和二维核磁共振光谱确定了分离化合物的平面结构和立体结构,并通过高分辨质谱进行了确认。
