oil cells of the fruit cortex but not in the seeds. 40 kg. of dried berries 

 produced 800 gr. of the essential oil on steam distillation, equivalent to 

 5.7% of the material used. 



The oil is pale yellow in color and mobile in nature with an 

 aromatic smell resembling that of citronella oil. When the oil is cooled 

 to 5°C. in a mixture of ice and salt, it turns turbid. 



On distillation in a fla;sk under atmospheric pressure, the oil begins 

 to boil at about 110°C. and continues to distill till 239°C.; the chief 

 fraction, however, boiled between 176°-186°, amounting to 80% of the 

 original oil. The viscous residue left in the frask after the distillation 

 amounted to 0.7% ; it is yellowish brown in color and possesses a peculiar 

 empyreumatic odour. 



The oil reduces ammoniacal silver oxide. It combines with bromine 

 strongly, evolving a considerable quantity of heat. When the oil is shaken 

 with a saturated bisulphite solution minute white crystals are formed. 

 A drops of oil dissolved in a small quantity of acetic acid anhydride and 

 shaken with a drop of concentrated sulphuric acid, the liquid assumes at 

 once a brownish violet color which turns brown and finally becomes 

 brownish violet again. A drop of the oil is dissolved in 1 cc of acetic acid 

 anhydride and shaken with a small quantity of anhydrous zinc chloride, 

 the liquid gives a pale yellow color which turns pale orange at once 

 and becomes perfectly brown after a while. It has a density dig^ 

 =0.8504, «!?= +46° 30', N!?= 1.46, acid value = 3.3, ester value = 19.28, 

 ester value after acetylation of the non-aldehyde constituent of the oil 

 =23.23, and aldehyde content=15%. 



The oil amounting to 350 grams, was shaken with a dilute caustic 

 potash solution and the alkaline liquid was acidified and extracted with 

 ether. By evaporating off ether, a reddish brown solid substance (18%) 

 is obtained which after recrystallizing from methyl alchool, was identified 

 to be palmatic acid by its melting point and the analysis of its silver salt. 



The aldehydic or the ketonic constituent of the oil, which was 

 subsequently separated from the oil by treating with a saturated bisulphite 

 solution, is a mobile liquid of pale yellow color with an agreeable smell. 

 It distills between 140°-240° under atmospheric pressure and seems to 

 consist at least of two substances, of which the one is colorless and the 

 other is yellow.
