saponifloation number 131. Akalis colour it yellowish-red, and strong sulphuric 
acid produces a brown mass. The fat is yellowish green, has a pleasant 
aromatic odour, and dissolves completely in chloroform, partially in ether or 
alcohol; it melts at 235°, and has iodine number 199, acid number 95, and 
saponification number 137. 
The greenish-yellow volatile oil contains eugenol and dissolves in chloro- 
form, ether, or alcohol ; it boils at 237° and has a sp. gr. t'069. Sulphuric 
acid colours it dark green, and bromine vapor orange-yellow. The tannin 
forms a brown amorphous powder, soluble in water and alcohol, giving a 
black precipitate with iron salts and reducing alkaline copper solution after 
boiling with dilute sulphuric acid. Calcium and manganese are present in 
the plant in combination with phosphoric, oxalic, and malic acids. (J. Ch. 
8. 1905 A I. 192).
