Triterpenoids from Mangifera indica

Two new triterpenoids, 25(R)-3-oxo-24-methylene cycloartan-26-ol and ψ- taraxastanonol have been isolated from the neutral fraction of the stem-bark of Mangifera indica (var/cv sarikhas). The acidic fraction of the same extract yielded three new tetracyclic triterpenoids, 3-oxo-23(R or S)- hydroxy cycloart-24-en-26-oic acid and both C-23 epimers of 3β,23-dihydroxy cycloart-24-en-26-oic acid. The structures were elucidated by spectroscopic and chemical methods.
