IV. Oill of Inugaya Seeds 



The oil is obtained by pressing the seeds of the Cephalotaxus drupacea 

 S. et Z. The nut which is found in a hard brown shell has a somewhat 

 resinous odour and contains 62.02% of the oil with 4.52% of water. The 

 oil can be produced of a manufacturing scale up to 28% of the weight 

 of the entire seeds. 



The cold drawn oil is of pale yellow color, being freely soluble in 

 ordinary solvents. Under the Eleiden test, the oil remains perfectly liquid 

 even after 24 hours' standing, at the end of which a small quantity of 

 yellowish brown visicous precipitate is formed on the bottom of the test 

 tube. It is a semi-drying oil and furnishes material for soap and blown 

 oil ; when rectified by alkali, it is likewise well suited for edible purposes. 



Physical and chemical constants of the oil are as follows: — 



Specific gravity 0.9222 



Solidifying point On cooling to.-12°C., a small amount 



of solid matter precipitates. 



Acid value 0.51 



Saponification value 195.6 



Iodine value 129.2 



Reichert-Meissl value 0.85 



Hehner value 97.06
