Identification of triterpenoids in chloroform extract of Agarista mexicana by MS and NMR.
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.
