Two new degrade triterpenoids from Levl.

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