【Abstract】 A new phenolic dauricine- type alkaloid, named"dauriciline", was isolated from the rhizome of Menispermum dauricum DC.It is a pale yellow powder. Based on spectrometric analysis (UV. FAB- M S and ~1HNMR)and chemical reaction the structure of the new alkaloid was elucidated as RR, 7,7 ’-demethyldauricine (Ⅵ).更多还原
