214 PHILIPPINE RESINS, GUMS, AND OILS 



locally in preparing anisado, which is a favorite alcoholic bev- 

 erage among the Filipinos, 



Brooks * examined the oil obtained from the leaves of this 

 species and states that : 



A quantity of leaves, weighing approximately 16 kilos, were distilled 

 with steam over a period of about five hours and 185 grams of colorless 

 oil were obtained. This oil resembled the fresh leaves in odor and pos- 

 sessed the following constants. Specific gravity, l^ =0.963; N ^ =1.5235; 



saponification number 3.6; the oil is inactive. * * * 



The oil has a faint odor of anise or anethol, which, together with the 

 constants, identifies it almost with certainty as methyl chavicol. For 

 further proof, a small portion was oxidized with potassium permanganate 

 to homoanisic acid, melting point, 84' to 86'. * * * 



Therefore, it is evident that the oil from Claiisemi contains methyl 

 chavicol to the extent of 90 to 95 per cent. * * * 



The occurrence of methyl chavicol, especially in such large proportions, 

 in one of the Rutaceae is quite novel. * * * 



Owing to the ease with which methyl chavicol is converted into anethol, 

 by treatment with alkalies, it is possible that this operation would be 

 successful commercially. Considerable quantities of anise oil are annually 

 imported into the Philippine Islands for the manufacture of anisado. How- 

 ever it is doubtful whether or not Clausena could successfully be cultivated, 

 as it is a typical forest species. 



Clause7ia ayiisum-olens is a small tree, 3 to 6 meters high. 

 The leaves are alternate, 20 to 30 centimeters long, compound, 

 with 7 to 11 leaflets which are inequilateral, pointed at the tip, 

 5 to 11 centimeters in length, and with toothed margins. The 

 leaves are aromatic when crushed. The flowers are greenish 

 white, fragrant, about 8 millimeters in diameter, and are borne 

 in panicles which are 15 to 20 centimeters long. 



This species is a native of the Philippines, is widely distrib- 

 uted, and is abundant in some places. It is occasionally cul- 

 tivated. 



Genus TODDALIA 



TODDALIA ASIATICA (L.) Kurz. 



Local names: Atdiigen, bugkdu, bukkdn, siibit (Benguet) ; daudg (Rizal). 



TODDALIA ASIATICA OIL 



According to D. Hooper.t the oil obtained by distilling the 

 leaves of this species has a pleasant odor resembling verbena 

 or basilicum. Gildemeister and Hoffman t state that the oil
