Two new degrade triterpenoids from Buxus bodinieri Levl.

Two new degrade cycloartane triterpenoids, named buboditones A, B (1, 2), together with ten known alkaloids, cyclobuxoviridine (3), N-dimethylcycloxobuxovircine (4), cyclovirobuxine C (5), cyclovirobuxine A (6), cycloprotobuxine C (7), cycloprotobuxine A (8), cyclobuxoxazine (9), cyclobuxoxazine A (10), buxruguline B (11), irehine (12), were isolated from the leaves and stems of Buxus bodinieri Levl., The structures of compounds 1-2 were elucidated by 1 D and 2 D NMR spectroscopic methods including HSQC, HMBC, H-1-H-1 COSY, NOESY, as well as HRESIMS spectroscopic analysis.
