The author presents experimental data to show that acetone might be 
used to advantage in the preparation of the official oleoresins. He es¬ 
pecially recommends the use of this solvent in the preparation of the 
oleoresin of ginger. The yield of oleoresin, using acetone as the extract¬ 
ing solvent for the various drugs, is reported to be as follows: aspidium, 
18 per cent; capsicum, 18 per cent. (25 per cent, when the drug was com¬ 
pletely exhausted); cubebs, 21.75 to 25 per cent; lupulin, 71 per cent; 
pepper, 5.93 per cent; ginger, 5.57 per cent; and parsley seed 24 per cent.

Three lots of extract of male fern gave 1.50, 2.10 and 1.50 per cent., 
respectively, of “moisture’ 7 and showed an ash content of 0.55, 0.55 and 
0.55 per cent., respectively.

The author states that the volatile oil of male fern is therapeutically 
active and that Poulsson’s statement based on the work of Carlbohm, 
Liebig and Rulle, that the activity is due to filix acid alone is erroneous. 
He cites as an example the activity of Aspidium athamanticum Kunze, which 
contains no traces of filix acid but contains the volatile oil.

16.4, 18.8, 21.06, 21.9, 23, 24.7, 24.8, and 24.8 per cent; ginger, 4 samples, 
3.85, 4.72, 5.2, and 5.4 per cent; lupulin, 1 sample, 66.5 per cent; crude 
whole male fern rhizomes, 2 samples, 9.27 and 9.87 per cent; peeled male 
fern rhizomes, 3 samples, 7.1, 7.26 and 8.9 per cent.
