saponification 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 chloroform, ether, or alcohol ; it boils at 237° and has a sp. gr. 1.069. 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. S. 1905 A I. 192).
