Rhizoma Filicis.

The author states that the rhizomes of Aspidium filix mas should give at 
most 3 per cent, of ash and should yield at least 8 per cent, of extractive 
matter to ether, allowing the latter to evaporate spontaneously and then 
heating for 2 hours at 95 °C, cooling in a desiccator and weighing. Three 
samples of rhizomes gave 2.52 to 2.92 per cent, of ash, respectively, and 
9.22 to 10.1 per cent, of ether-soluble extract.

In connection with his work on the tannic acid in the male fern rhizomes, 
the author presents the results obtained in extracting the drug in a Soxh- 
let’s apparatus with various solvents, ether, benzol, and petroleum ether. 
At the end of six hours, extraction was found to be practically complete in 
all cases. The yield obtained in each case is given as follows; ether, 10.0 
per cent., benzol, 9.06 per cent., petroleum ether, 9.08 per cent. 
Extraction with alcohol of varying strength yielded extractive matter 
in the following quantities: alcohol (90 per cent.), 20.0 per cent., alcohol 
(96 per cent.), 16.6 per cent. 
The fixed oil content of the ethereal extract is stated to be 70 to 75 
per cent.

Evans Sons Lescher & Webb, Analyt. Notes, 1, p. 21. 
The oleoresin extracted by ether from four samples of cubebs amounted 
to (1) 22.08, (2) 22.6, (3) 21.13 and (4) 22.8 per cent., respectively.

Five samples of cubeb are reported which assayed from 18.85 to 26.88 
per cent, of oleoresin.
