Two new C19-diterpenoid alkaloids, circinadines A (1) and B (2), were isolated from the roots of Aconitum hemsleyanium var. circinacum. Their structures were elucidated by chemical evidence and spectral analyses, including ESI-MS, HR-EI-MS, 1D- and 2D-NMR.
从circinacum乌头变种的根中分离出两种新的C19 - 二萜生物碱,环宁定A(1)和环宁定B(2)。通过化学证据和光谱分析,包括电喷雾电离质谱(ESI - MS)、高分辨电子轰击质谱(HR - EI - MS)、一维和二维核磁共振(1D - 和2D - NMR)对它们的结构进行了阐明。
