The  crystals  melt  at  110°  C.  and  are  identical  with  those  found  in  the 
root  bark.  The  volatile  oil  is  aromatic  and  pleasant,  resembling  in 
odor  a  mixture  of  bergamot  and  orange  flower  oils.  The  reactions 
are  as  follows:  Strong  sulphuric  acid  added  to  a  chloroform  solution 
gave  a  greenish  color  which  changed  to  a  purplish-red  ;  ferric  chloride 
and  sulphuric  acid  gave  a  light  green  color,  Avhich  gradually  changed 
to  brown  and  red  brown. 
2.  Ether  extraction. — The  portion  insoluble  in  petroleum  spirit  was 
treated  with  ether.  The  soluble  portion  amounted  to  1"1  per  cent.,  of 
which  0'2  were  crystals  and  0  9  resin.  The  extract  is  partly  soluble 
in  potassium  hydrate  and  is  precipitated  on  neutralization.  The  crystals 
have  a  bitter  taste  and  the  reactions  obtained  show  it  to  be  identical 
with  the  glucoside  from  the  leaves. 
3.  Treatment  with  absolute  alcohol. — Tiie  powder  was  next  treated 
with  absolute  alcohol.  The  total  extract  amounted  to  9*25  per  cent., 
of  which  ()"12")  \)Qv  cent,  was  soluble  in  water.  Tiie  glucoside  was 
only  found  in  the  etherial  solution  as  it  existed  only  in  a  minute 
quantity. 
■4.  Aqueous  maceration. — The  powder  insoluble  in  the  foregoing 
was  treated  with  the  requisite  quantity  of  water  ;  in  this  case  double 
the  quantity  was  used,  making  the  proportion  1:20.  The  precipitate  by 
alcohol  amounted  to  2*48  per  cent.  The  total  extract  was  7*48  percent. 
Alkaline  extraction. — The  powder  was  next  treated  with  0*2  per 
cent,  solution  of  sodium  hydrate.  The  portion  soluble  amounted  to 
4  per  cent.,  of  which  1  j^er  cent,  was  precipitated  by  alcohol  and  acetic 
acid  to  neutralization. 
(3.  Treatment  with  diluted  acid. — The  insoluble  powder  from  the 
last  treatment  was  treated  with  diluted  2  per  cent,  liydrochloric  acid. 
The  total  extract  amounted  to  2'6  per  cent.,  about  1  per  cent,  was  pre- 
cipitated by  ammonia  and  consisted  mostly  of  iron.  The  remaining 
insoluble  powder  after  bleaching  amounted  to  62*3  per  cent. 
Seeds. — The  moisture  of  the  seeds  amounted  to  7  per  cent,  and  the 
ash  2-222  per  cent.,  the  solubilities  of  which  were  as  follows  : 
Soluble  in  water   -834 
Soluble  in  hydrochloric  acid  1*444 
Insoluble  in  either  (silica)   '444 
  2*222  i^er  cent. 
The  qualitative  analysis  resulted  as  follows  :  Acids :  sulphuric, 
hydrochloric  and  phosphoric ;  Bases :  iron,  aluminium,  magnesium, 
potassium,  sodium.
