title: Steroidal constituents from the aerial parts of Lippia nodiflora Linn.
abstract: 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.
