carbonyl compound, previously isolated from the stems of Ma/lotus paniculatus, has been proved
to be 29-nor-21&I-hopane-3,22-dione. The light petrol extracts of both the leaves and stems of M. hookerianus
have been found to contain friedelin, friedelan-3fi-ol and sitosterol, and the ethanol extract of the former two
new triterpene acids, 3-oxours-12-ene-27,28-dioic and 3/?,28-dihydroxyurs-12-en-27-oic acids.
