It gives a dark indigo-blue coloration with Erdmann’s reagent, a pale rose-red 
with pure sulphuric acid, and a reddish-brown with nitric acid. A base, 
which seems to be identical with laurotetanine, is also found in the varieties 
of Tetranthera, Notophoebe, Apornla, Actiuodaphne and Uligera pulchra. It 
is also possible that Laurotetanine is the alkaloid discovered in 1886 by 
Eijkman in Haasia squarrosa, Z. et M. (Meded. nit S’Lands Plantentuin, vii, 
p. 77-101.)— (Pharmacog. Ind. Ill , 2l2.) 
The seeds yield a solid white fat called in Java Tang kala fat. The fat 
melts at 42" and has acid values ranging from 3'8 to 8'8 ; specific gravity at 
41°, 0 a 1784 ; saponification value, 268 2; iodine value 2'28 ; Reichert-Meissl 
value, 1'47 ; Hehner value, 76-1. The fat appears to contain olein 2 6, laurim 
96'0 per cent. (A. Schroeder, Archiv, Pliarm., 1905, 243, 028.)
