|
| Authors: | Manik C Das |
| Abstract: | The acid hydrolysate of the ethanol extract of Careya arborea leaves afforded a new triterpenoid lactone designated careyagenolide along with maslinic acid and 2α-hydroxy ursolic acid. The structure of careyagenolide has been established as 2α, 3β-dihydroxytaraxastan- 28, 20β-olide by a variety of spectroscopic evidence, chemical transformations and correlation with ψ-taraxasterol. |
