Key Word Index - Mangifera indica; Anacardiaceae; triterpinoids. - From the neutral fraction of the n-hexane extract of stem bark of Mangifera indica (var./cv Banganpalli) six new tetracyclic triterpenoids, cycloart-24-ene-3β,26-diol, the C-24 epimers of cycloart-25-ene-3β,24,27-triol, the C-24 epimers of cycloartane-3β,24,25-triol and 3-ketodammar-24E-ene-20S,26-diol together with known compounds cycloartenol, α-amyrin, β-amyrin, sitosterol, 3β-hydroxycycloart-25-en-26-al, dammarenediol II, the C-24 epimers of cycloart-25-ene-3β,24-diol, 24-methylenecycloartane-3β,26-diol, ψ-taraxastane-3β,20-diol and ocotillol II have been isolated.The acidic fraction of the same extract, on esterification with diazomethane followed by chromatography, yielded methyl mangiferonate, methyl isomangiferolate, methyl mangiferolate and diazomethane adduct of methyl mangiferolate.The structures were elucidated by spectroscopic and chemical methods.
