The bastard sandal, Erythroxylon monogynum, Roxb., is a shrub or small tree which grows in the western parts of the East Indies and in Ceylon. From the wood the natives prepare an oil which they obtain by placing pieces of the wood in an earthenware pot which is heated over direct fire. The volatile product is collected in a second pot inverted over the first one. It is known as Dummele and is used for varnishing boats1).
By means of steam distillation of the wood, Schimmel & Co.2) obtained 2,56 p.c. of an oil which constituted a sticky mass of crystals and the odor of which reminded of that of guaiac wood oil. The specific gravity is less than 1; A. V. 6,77; E. V. 1,56; m.p. 42 to 45°; E. V. after acetylation 131; soluble in 1 vol. of 90 p.c. alcohol with but faint turbidity which disappears upon the addition of more alcohol.
For the purpose of investigating the crystalline constituent, the last fraction of the oil was subjected to distillation in vacuo. Fraction 212 to 216° (8 mm.) was dissolved in petroleum ether and the ethereal solution subjected to a low temperature. After two subsequent recrystallizations from petroleum ether, shiny needles, melting at 117 to 118° ([a]D in 13 p.c. chloroform solution + 32° 28') were obtained, the analysis of which yielded results in agreement with the formula C20H82O. The substance is an alcohol the acetate of which melts at 72 to 73° and which has the formula C22H3402.
