Ether, 3 a sufficient quantity. 
Put the Black Pepper into a cylin¬ 
drical percolator provided with a 
stop-cock, and arranged with cover 
and receptacle suitable for volatile 
liquids, 4 press it firmly, and gradually 
pour ether upon it, until twenty fluid 
ounces of liquid have slowly passed. 0 
Black Pepper 
Recover the greater part of the ether 
by distillation on a water-bath, 6 and 
expose the residue, in a capsule, until 
the remaining ether has evaporated, 7 
and the deposition of piperin in crys¬ 
tals has ceased. Lastly, separate the 
oleoresin from the piperin by expres¬ 
sion through a muslin strainer, 8 and 
keep it in a well-stopped bottle. 9

Stronger Ether, 3 a sufficient quantity. 
Put the pepper into a cylindrical 
percolator, provided with a cover and 
receptacle suitable for volatile liquids, 4 
press it firmly, and gradually pour 
stronger ether upon it, until one hun¬ 
dred and fifty (150) parts of liquid 
have slowly passed. 6 Recover the 
greater part of the ether by distilla¬ 
tion on a water-bath, 6 and expose the 
residue, in a capsule, until the re¬ 
maining ether has evaporated, 7 and 
the deposition of piperine, in crystals, 
has ceased. Lastly, separate the 
oleoresin from the piperine by ex¬ 
pression through a muslin strainer. 8

of Pepper 
from the percolate by distillation on a 
water-bath, 6 and, having transferred 
the residue to a capsule, set this aside 
until the remaining ether has evapor¬ 
ated, 7 and the deposition of crystals of 
piperine has ceased. Lastly, sepa¬ 
rate the oleoresin from the piperin by 
expression through a muslin strainer. 8 
Keep the oleoresin in a well-stop¬ 
pered bottle. 9
