Summary

From the unsaponifiable matter of the fixed oil of the wood ofPterocarpus marsupium, two phytosterols have been obtained. One of these has been named ‘pterocarpol A’, having a molecular formula C27H46O.2H2O after drying in air and C27H46O after drying at 100°C.in vacuo. The other phytosterol has been named ‘pterocarpol B’, having a molecular formula C27H46O after drying at 110°C.in vacuo.

Both have been found to contain an alcoholic hydroxy group as these give monoacetyl derivatives. Further pterocarpol A gives a monobenzoyl, a monoacetyl dibromide, a monophenylurethane and a digitonide derivative. Monoacetyl dibromide and digitonide derivatives of pterocarpol B have been also obtained.
