296  An  Examination  of  Commercial  Fluid  Extracts.  {AmjJney'i895.arm' 
The  following  were  the  figures  obtained : 
(1)  Twenty  samples  were  examined  of  this  firm,  and  they  are  ar- 
ranged according  to  the  amount  of  glucose  found. 
Five  percent,  and  over.  F.  E.  Taraxacum,  Triticum,  Gentian  and 
Cimicifuga. 
Four  per  cent.  F.  E.  Cascara  Sagrada.    3-5  per  cent.  F.  E.  Rheum. 
2-5  per  cent.  Buchu,  Prunus  Virginiana,  Senna,  Hydrastis,  Ascle- 
pias. 
One  per  cent.  Grindelia  Robusta,  -833  per  cent.  Humulus  and 
Digitalis,  -5  per  cent.  Ipecacuanha. 
F.  E.  Belladonna  leaves,  Calumba  and  Nux  Vomica,  also  con- 
tained sugar  in  small  amount,  but  no  quantitative  estimation  was 
made. 
F.  E.  Coca  contained  less  than  05  per  cent. 
F.  E.  Cubeb,  which  was  also  examined,  was  found  perfectly  free 
from  all  saccharine  matter. 
(2)  From  this  source  8  samples  were  examined,  quantitative  de- 
terminations being  made  in  each  case. 
The  largest  percentage  found  was  5  per  cent,  in  F,  E.  Pulsatilla  ; 
3*5  per  cent,  was  found  in  Cypripedium  ;  3  per  cent,  in  Buchu;  2  5 
per  cent,  each  in  Frangula,  Ipecacuanha  and  Pilocarpus;  -5  per  cent, 
in  Rhus  Glabra,  while  the  smallest  amount  found  was  in  F.  E.  Dam- 
iana,  namely,  -35  per  cent. 
(3)  Five  extracts  were  examined  from  this  source. 
The  average  glucose  percentage  of  these  preparations  was  small, 
the  largest  amount  being  found  in  F.  E.  Stillingia,  which  contained 
1-66  per  cent.,  the  smallest  in  F.  E.  Aconite  Root,  which  only  gave 
indication  to  the  extent  of  -I  per  cent. 
F.  E.  Dulcamara  contained  about  15  per  cent.;  Belladonna  root, 
1-25  percent.  ;  and  Eucalyptus,  -625  per  cent. 
(4)  This  source  furnished  5  samples. 
The  largest  amount  was  found  in  F.  E.  of  Phytollacca,  the  fruit, 
which  was  over  7  per  cent. 
This  is,  however,  no  criterion,  as  the  drug  contains  considerable 
fruit  sugar. 
F.  E.  Granati  Rad.  Cortex  gave  indication  of  -67  per  cent.;  Eu- 
phorbia pilulifera,  -5  per  cent. 
F.  E.  Pichi  and  Quebracho  were  also  examined,  and  revealed  but 
small  amounts,  so  that  a  quantitative  estimation  was  not  made.
