title: Two new C19-diterpenoid alkaloids from Aconitum hemsleyanium var. circinacum.
abstract: 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.
