摘要：

From the neutral fraction of the n-hexane extract of stem bark of M. indica, (var./cv Banganpalli) six new tetracyclic triterpenoids, cycloart-24-ene-3.beta.,26-diol, the C-24 epimers of cycloart-25-ene-3.beta.,24,27-triol, the C-24 epimers of cycloartane-3.beta.,24,25-triol and 3-ketodammar-24E-ene-20S,26-diol together with the known compounds cycloartenol, .alpha.-amyrin, .beta.-amyrin, sitosterol, 3.beta.-hydroxycycloart-25-en-26-al, dammarenediol II, the C-24 epimers of cycloart-25-ene-3.beta.,24-diol, 24-methylenecycloartane-3.beta.,26-diol, .psi.-taraxastane-3.beta.,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 the diazomethane adduct of methyl mangiferolate. The structures were elucidated by spectroscopic and chemical methods.
