New essential oils. 



Magnolia Oil. From Japan we received a sample designated 

 as magnolia oil, as to the origin of which we were unable to ascer- 

 tain any further details. It was a limpid, bright-yellow oil, and had 

 the following constants: d^o 0,9100; «i> -{- 14 io'; soluble in about 

 7 and more vol. 80 per cent, alcohol with minute turbidity. Of con- 

 stituents, cineol and phellandrene could be detected; the oil probably 

 contains also linalool and terpineol. According to the results of this 

 examination, it appears to be out of the question that this magnolia 

 oil is identical with the kobushi oil from Magnolia Kobus D. C. 1 ) 

 previously examined by us. 



Pharmacopoeias. 



American Pharmacopoeia (U. S. Ph.). 



On the part of the American Pharmacopoeia Committee, Supple- 

 ments to the U. S. Ph. have been published on the 1 May and 1 June 

 1907, which contain partly corrections of various statements, and 

 partly additions to the individual articles. In the case of the essential 

 oils, various alterations have also been made, but unfortunately not 

 to such an extent as in our opinion appeared desirable. We quote 

 the various data below without comment, as all further particulars are 

 found in our previous discussion of the Pharmacopoeia 2 ) to which we 

 here beg to refer.

Caraway Oil. d 2 5o 0,900 to 0,9 1 o. 



Copaiba Oil, The requirement of solubility has been cancelled. 



Erigeron Oil 1 ). «d 2 5° not below -f~45°- 



*) It should be mentioned here still that in recent times we have had to deal 

 repeatedly with authentic erigeron oils which had a distinctly higher specific 

 gravity than that allowed by the American Pharmacopoeia. The specific gravities

of the oils in question amounted up to 0,887 at -^, corresponding to 0,881 at ^q. 



Eucalyptol. d 2 5o 0,921 to 0,923. 



Eugenol. d 25 o 1,066 to 1,068.
