A new steroidal alkaloidal glucoside, C34H57NO7, mp 284-286 degrees C, named ningpeisinoside, was isolated from the bulb of Fritillaria ningguoensis S.C. Chen et S.F. Yin. Based on preparation of derivatives and IR, MS, 1HNMR, 13CNMR spectral studies, the structure of ningpeisinoside has been established as N-methyl-5 alpha-veratranine-6-oxo-3 beta-O-beta-D-glucoside(I).
从宁国贝母（Fritillaria ningguoensis S.C. Chen et S.F. Yin）的鳞茎中分离出一种新的甾体生物碱苷，化学式为C34H57NO7，熔点284 - 286℃，命名为宁贝母苷。基于衍生物制备以及红外光谱（IR）、质谱（MS）、核磁共振氢谱（1HNMR）和核磁共振碳谱（13CNMR）光谱研究，宁贝母苷的结构已确定为N - 甲基 - 5α - 藜芦胺 - 6 - 氧代 - 3β - O - β - D - 葡萄糖苷（I）。
