Detailed structural study of the major triterpenoids from chloroform extract of Agarista mexicana revealed the presence of new pentacyclic triterpene lactone 3ss-hydroxy-ursan-28ss, 19ss-olide together with four known compounds, 12-ursene, campesterol, stigmasterol, sitosterol. These compounds were isolated by chromatography and their structures confirmed by NMR experiments and by MS.
