Capsules from only two manufacturers contained extract of male fern 
of which the crude filicin content was higher than 20 per cent. The ex¬ 
tract of male fern in capsules from four other sources showed a filicin 
content of from 8.57 to 16.02 per cent. (p. 48.)

Extractum Filieis. 
Caesar and Loretz, Jahres-Ber., Oct., pp. 23, 37, and 96. 
The method of S. Yagi for the physiological standardization of the extract 
of male fern is stated to be too cumbersome for practical use. (p. 23.) 
Extracts prepared in the laboratory showed the following crude filicin 
content, 25.48, 24.85, 29.7, 26.04, 26.0, 35.58, 27.35 and 33.79 per cent, 
(p. 37.) 
It is further stated that the yield of ether extract, after evaporating on 
a water bath at 60°C to constant weight and drying in a desiccator for 
half an hour, should be about 15 to 18 per cent. (p. 96.)

It is stated that the former solvent, acetone, is to be changed to ether 
in the following: Oleoresina Aspidii, Oleoresina Capsici, Oleoresina 
Zingiberis and Oleoresina Piperis. (p. 551.) 
Directions are also given for the preparation of Oleoresina Petroselini

It is stated that a large portion of the extract of male fern made in Ger¬ 
many shows a crude filicin content of less than 15 per cent., while the Swiss 
Pharmacopoeia requires a content of 26 to 28 per cent. The author, 
therefore, thinks it desirable that a method for the estimation of the crude 
filicin in this preparation be given in the German Pharmacopoeia.
