Abstract

Eight previously undescribed norditerpenoid alkaloids, pseudophnines A-D, pseudorenines A-B, and pseudonidines A-B, together with ten known norditerpenoid alkaloids, tianshanisine E, sharwuphinine B, potanisine A, lycoctonine, delbruline, isondelpheline, delavaines A-B, and shawurenines A-B were isolated from the whole plant of Delphinium pseudoaemulans C. Y. Yang et B. Wang. Their structures were established on the basis of spectroscopic analyses, including HR-ESI-MS, 1D and 2D NMR analysis. Additionally, no cytotoxicity was observed against A549 and HeLa cancer cells of these diterpenoid alkaloids when evaluated in vitro using the MTT method.
