Steroidal constituents from the aerial parts of Lippia nodiflora Linn.
The methanolic extract of the aerial parts of Lippia nodiflora Linn. afforded one new and two known steroids. The structure of the new steroid had been elucidated as 4',5'-dimethoxybenzoloxystigmasterol (1) by an analysis of the spectral data, including extensive NMR experiments and its chemical transformation to stigmasterol. The known steroids were identified as stigmasterol and beta-sitosterol through comparison of their spectral data with those reported in the literature.
