| Résumé: | Two new triterpenoids pergularine A and pergularine B [1], along with five known triterpenoids were
isolated from the ethanolic extract of the aerial parts of P. tomentosa L. (Asclepiadaceae). The structures of the isolated
known compounds were identified as 3-epi-Micromeric acid (1), taraxasterol acetate (2), taraxasterol (3), 16α-
hydroxytaraxasterol acetate (4) and α- amyrine (5) and were reported for the first time in the genus Pergularia.
Structures were elucidated by chemical and spectroscopic methods (2D-NMR, IR, and MS) and by comparison with
literature data. |
