New York, September, 1895. No. 9. SANTAL WOOD OIL. By E. J. PARRY, In the recent advances made in quan- titative methods for the examination of essential oils, santal oil appears to have been entirely neglected. Chapoteaut, after a very careful study of the oil, an- nounced some time ago that it consisted almost entirely of two bodies C15H2,;0, an alcohol termed santalol, and C15H240, probably the corresponding aldehyde, which only occurs in small quantities. These facts made me think that a quan- titative method for the estimation of the value of the oil would not be difficult to apply. Naturally, I turned my attention, in the first place, to the presence of the aldehyde; but, although unable to devise any modification of the well-known bi- sulphite method to separate this body, I was able to confirm its presence, and hope later on to have a method for its estimation to announce. The alcohol then, of course, occupied my attention. I may here mention that there are pres- ent in normal santal oil traces of an acid probably due to oxidation of the two bodies above mentioned, and variable LIBRARY NEV BOTAf OAk quantities of a saponifiable oil, possibly an ester of santalol. Santalol, however, appears to constitute the bulk of the oil, and the aldehyde lowers the gravity of the oil, while the saponifiable oil raises it. After a number of experi- ments, I found that the best way of valu- ing the oil was by an estimation of the amount of santalol (or other alcoholic bodies if they are present, expressed in terms of santalol). This is effected by conversion of the santalol into an acetate and an estimation of the amount of acetic acid present in the acetylated oil. To save tedious calculations, the result may be expressed in terms of potash necessary to saponify the acetylated oil. About 10 grs
