Fluidglycerate  oe  Coffee. 
Take  of  Coffee  in  number  40  powder  100  Gm. 
Proceed  according  to  the  type  process,  using  60  c.c.  of  the 
glycerol-water  menstruum  to  moisten  the  drug. 
Fluidglycerates  of  both  green,  or  unroasted,  and  of  roasted,  coffee 
were  prepared,  and  both  appear  to  be  satisfactory  preparations. 
That  of  the  roasted  coffee  will  fill  a  demand  that  is  growing  in 
the  trade  for  a  concentrated  extract  of  coffee  for  making  syrup, 
flavoring  for  ice  cream,  soda  water,  etc.    The  following  formula  is 
submitted  for 
Syrup  of  Coffee. 
Take  of  Fluidglycerate  of  Roasted  Coffee   10  c.c. 
Syrup    70  c.c. 
Mix. 
The  product,  while  only  one-half  the  coffee  strength  of  the  N.  F. 
formula  for  syrup  of  coffee,  will  be  found  quite  strong  enough  for 
soda  water  syrup,  and  if  a  stronger  syrup  is  wanted  the  proportion 
of  the  fluidglycerate  can  be  increased. 
Fluidglycerate  of  Colchicum  Corm. 
Take  of  Colchicum  Corm  in  number  20  powder  100  Gm. 
Acetic  Acid    10  c.c. 
Mix  the  acetic  acid  with  50  c.c.  of  the  glycerol-water  mixture  and 
moisten  the  drug  with  the  mixture  and  then  proceed  as  per  the 
type  process. 
In  this  preparation  there  separated  a  starch-like  sediment  amount- 
ing to  about  10  c.c,  which  was  strained  out,  and  the  liquid  has  since 
remained  clear.  It  has  a  bitter  and  acidulous  taste  and  mixes  cle^r 
with  syrup  and  cloudy  with  alcohol  and  slightly  cloudy  with  water 
or  diluted  alcohol.  Assayed  by  the  official  process  for  assay  of 
Fluidextract  of  Colchicum  Seed  it  gave  0.290  Gm.  colchicine  in 
100  c.c. 
Fluidglycerate  of  Colchicum  Seed. 
Take  of  Colchicum  Seed  in  number  20  powder  100  Gm. 
Acetic  Acid   15  c.c. 
Mix  the  acetic  acid  with  60  c.c.  of  the  menstruum  of  glycerin 
and  distilled  water  and  moisten  the  drug  with  this;  then  proceed 
according  to  the  type  process.
