Results obtained in the ex¬ 
traction of 5 samples of 
cubeb. 
Reported as yield of oleoresin. 
Results obtained in the ex¬ 
traction of 4 samples of 
cubebs. 
Reported as yield of oleoresin. 
On subsequent ext? action with 
alcohol 3.40 to 5.66 per cent, 
of extractive matter was ob¬ 
tained. 
Reported as yield of oleoresin. 
Results obtained in the ex¬ 
traction of 6 samples of 
cubebs. 
Reported as yield of oleoresin. 
The average yield of 5 samples 
of cubebs is given as 6.95.
