The Structure of △"-Dehydroaloperine

Wang Zhong- xiao, Zhang Shu-sen, Fang Sheng-ding, Zhang Rui and Yu Han-gang   

Abstract: A new alkaloid named ll-dehydroaloperine was isolated from the leaves and stalks of Sophora alopecuroides L. during flowering. Total alkaloid was obtained by diluted acid percolation and cation-exchange resin, then the new alkaloid was obtained via various polar solvent extraction under various pH value and Al2O3 column chromatography. The new alkaloid was proved to be analogous to aloperine through UV, IR, and mass spectrometry. Its structure was further identified by 1HNMR, 13CNMR, 1H-1H cosy spectrum, NOE as well as by some other chemical methods.
