From the Syndicat du Geranium Bourbon, the firm of Schimmel & Co.5), received an oil of Evodia simplex, Cordem. (family Rutaceae) which is a native of Reunion. From which part of the plant the oil is obtained is not known. d15o0,9737; aD - 13°4'; A. V. 2,1; E. V. 16,4; E. V. after acetylation - 63,3.
The oil was soluble in 0,9 vol. of 80 p.c. alcohol with the separation of small amounts of paraffin. In 10 vol. of 70 p.c. alcohol it was not completely soluble. After it had been ascertained that nothing distilled over below 190° under ordinary pressure, the oil was fractionated in vacuo (3 mm.), when it distilled between 90 and 140°. A second distillation under 2,5 mm. yielded a fraction between 97 and 100° (d15o1,006; aD - 4°) which consisted of eugenol methyl ether. Oxidation with permanganate yielded veratric acid which crystallized in colorless, thin needles that melted at 177,5°.

From the last fraction of the oil paraffin crystallized that melted at 80 to 81°.
