ART. XXXV.— ON EXTRACTS OF THE SOLANE^E CONTAIN- 
ING GREEN FECULA. By MM. M. Solon and Soubeiran. 
The extracts prepared from the unpurified juices of plants, 
and consequently containing green fecula, have been highly 
praised by Storck, and are generally considered as efficacious 
preparations. In the greatest number of plants, what is im- 
properly termed green fecula, is a mixture of chlorophylline, 
coagulated gluten, &c. &c. all of which are without any medical 
properties, but it would be wrong to suppose that this was 
the case in every instance; and it is very doubtful if what is 
true as regards most vegetables is applicable to the active 
species on which Storck experimented, though at the same 
time we may be permitted to doubt the validity of the prac- 
tice of those pharmaceutists who considering the green fecula 
as the only active part of these plants, have not hesitated to 
replace them in many preparations by the fecula obtained 
from them. If their opinion was founded on facts, vegetable 
juices deprived of their fecula by coagulation, would be desti- 
tute of all active properties, which is far from being the case. 
In the absence of chemical observations on the composition 
of the green fecula of the Solaneae, we have resorted to expe- 
rience to determine the point, for if this green fecula is active, 
it should be always united to extracts; if, on the contrary it 
adds nothing to their remedial virtues, it should be rejected 
as it only adds to their bulk. It is scarcely necessary to say 
that our experiments having been made on belladonna, hyo- 
scyamus and stramonium, our conclusions are applicable to 
these plants only, and we do not pretend to extend them by 
induction to other vegetable juices.
