摘要：

Four new alkaloids, compounds 1 - 4, based on the germine (= 4,9-epoxycevane-3,4,7,14,15,16,20-heptol; 5) framework, were isolated from the rhizomes of V dahuricum, together with germine proper. The X-ray crystal structure of germine (5) was solved, and all compounds were characterized by circular dichroism, 1D- and 2D-NMR (H-1,H-1-COSY, DEPT, HSQC, HMBC), as well as HR-MS analyses.
