ture  results.  Upon  evaporating  from  it  the  alcohol  at  I50°F.  the 
residuum  separates  into  a  reddish  oil, and  a  stiff  gummy  substance,  C. 
Characteristics  of  the  Oil,  B. — It  is  heavier  than  vi^ater.  The 
odor  and  taste  is  exactly  like  that  imparted  when  the  root  is  chewed. 
It  dissolves  in  alcohol,  ether,  chloroform  and  disulphide  of  carbon,  but 
from  the  latter  solution  a  small  amount  of  flocculent  reddish  matter 
separates.  When  the  solution  in  disulphide  of  carbon  is  filtered,  a  light- 
colored  oil  results,  seemingly  similar  to  the  essential  oil  obtained  by 
distillation,  the  color  being  somewhat  darker.  The  flocculent  red  pre- 
cipitate is  astringent  and  deliquescent,  absorbing  moisture  and  forming 
a  red  liquid.  It  is  the  material  that  gives  the  red  color  to  the  oil  R 
and  constitutes  a  considerable  proportion  of  the  bulk  of  the 
Gummy  Substance,  C. — This  is  purified  from  adhering  oil  by  tritu- 
ration with  carbon  disulphide,  the  residuum  being  granular,  astringent 
and  peppery,  and  of  a  brownish  color,  soluble  in  dilute  alcohol,  and 
mostly  soluble  in  glycerin.  It  dries  by  exposure  to  cool  atmosphere,, 
but  melts  to  a  red  varnish-like  substance  at  the  temperature  of  I25°P\ 
to  i5o°P\  When  the  dry  powder  is  triturated  with  water  a  flocculent 
substance  remains,  astringent  to  the  taste,  soluble  in  glycerin,  alcohol, 
and  dilute  alcohol ;  insoluble  in  chloroform,  ether  and  carbon  disul- 
phide ;  precipitates  black  from  solution  in  glycerin  and  dilute  alcohol,, 
with  ferrous  sulphate,  and  is  negative  to  action  of  the  usual  precipi- 
tants  for  alkaloids.  The  filtrate  from  the  precipitate  C,  after  rubbing 
with  water,  is  almost  colorless,  astringent,  precipitates  black  with 
ferrous  sulphate,  and  when  boiled  with  Fehling's  solution  yields  a  heavy 
red  precipitate.  It  fails  to  respond  to  reagents  for  alkaloids.  When 
the  precipitate  C  is  triturated  with  ether  and  chloroform  a  portion 
dissolves  and  an  astringent  substance  remains,  which  deliquesces  upon 
exposure,  forming  a  red  gummy  substance,  eventually  liquefying.  This 
seems  to  be  the  same  as  the  substance  that  separated  from  the  oil  B  by 
the  action  of  carbon  disulphide. 
The  residuum  within  the  percolator,  after  extraction  with  alcohol,, 
seemed  thoroughly  exhausted.  Water  and  acidulated  water  are  some- 
what astringent  after  maceration  with  it,  odorless,  react  with  Fehling's 
solution,  but  not  with  tests  for  alkaloids.  Ether  and  disulphide  of 
carbon  fail  to  extract  a  vegetable  wax,  resin  or  other  constituent  worthy 
of  attention,  and  inert  extractive  matter  and  mineral  salts  of  na 
importance,  together  with  woody  matter,  thus  far  have  been  found.
