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.

来自花翠雀 CY Yang et B. Wang 的降二萜生物碱

8 种以前未描述的去甲二萜生物碱、伪酚 AD、伪肾素 AB 和伪肾素 AB，连同 10 种已知的降二萜生物碱、天山素 E、沙乌茶碱 B、potanisine A、lycoctonine、delbruline、isondelpheline、delavaines 是从全株 AB 中分离得到的Delphinium pseudoaemulans CY Yang et B. Wang。它们的结构是在光谱分析的基础上建立的，包括 HR-ESI-MS、1D 和 2D NMR 分析。此外，当使用 MTT 方法进行体外评估时，未观察到这些二萜生物碱对 A549 和 HeLa 癌细胞的细胞毒性。
