62 OIL-BEARING SEEDS INDIGENOUS TO QUEENSLAND. 



The comparatively high iodine value point.s to the 

 presence of linoleic or linolenic acids. 



In the products of oxidation by alkaline permanganate 

 were identified dioxystearic acid (M. Pt. 130° C.) and a 

 tetrahydroxy-stearic acid (sativic acid) (M. Pt. 156°- 

 160° C). No Hnolenic hexabromide was yielded in the 

 hexabromide test. 



The liquid fatty acids are. therefore, oleic and linoleic- 

 acids. 



The Solid Fatty Acids were fractionally crystallised 

 from alcohol and were obtained in successive portions 

 melting from 60-62° C; approximating to the melting jioint 

 of palmitic acid, which is, therefore, the solid fatty acid 

 present. 



No indication was ol)tained of the presence of lauric 

 acid, the glyceride of which constitutes a large portion 

 of other oils of the N. O. Laurin^ described, such as oils 

 of Laurus nobilis (common laurel oil), Litscea sebifera, 

 L. Stocksii and L. zeylanica. 



Summary. 



( 1 ) The oil of the seeds of Hernandia bivalvis is associated 

 with a bitter principle, a resin acid, and a resin oil. 



(2) It consists of olein, linolein and palmitin ; laurin^ 

 which is a constituent of other oils of N. 0. Laurin.®, 

 is not present.
