Abstract
Six new bis-spirolabdane-type diterpenoids, leosibirinone A (1), 3αa-acetoxyleoheteronone C (2), leosibirinone B (3), 3α- hydroxyleoheteronone A (4), 3α-acetoxyleoheteronone E (5), and 3α-acetoxy-15-epileoheteronone E (6), were isolated from the aerial parts of Leonurus sibiricus. Their structures were identified on the basis of ID and 2D NMR, including 1H-1H COSY, HSQC, HMBC, and NOESY spectroscopic analyses.
