CHEMICAL  NOTES. 
By  Henry  C.  C.  Maisch,  Ph.G.,  Ph.D. 
Test  for  purity  of  quinine  sulphate. — E.  Hirschsohn  {Pharm. 
Zeitsc/ir.f.  Russland,  1890,  xx,  p.  1)  gives  the  following  method  for 
determining  whether  sulphate  of  quinine  is  chemically  pure  :  o-2 
gm.  of  the  salt  is  well  shaken  with  5  cc.  of  a  mixture  of  30  pts.  by 
volume  of  petroleum  ether  (sp.  gr.  o-68o)  and  70  pts.  of  chloroform, 
and  filtered  immediately.  To  the  perfectly  clear  filtrate  three 
volumes  of  petroleum  ether  are  added.  Pure  quinine  sulphate 
yields  a  clear  solution  while  all  other  cinchona  alkaloids  show  opales- 
cence or  give  precipitates.  According  to  the  author,  o-i  per  cent, 
of  the  accompanying  alkaloids  can  still  be  detected  by  this  method. 
On  Tiliacin. — P.  A.Latschinow  (8th  Congress  of  Scient.and  Physic, 
in  St.  Petersburg;  through  Chem.  Zeit.,  1890,  p.  126)  found  in  the 
linden  (Tilia)  leaves  a  glucoside,  tiliacin,  which  can  be  split  into 
glucose  and  tiharetin.  The  latter  is  decomposed  further  into  anisic 
acid  and  other  bodies  not  further  studied.  The  leaves  of  Cirsium 
arvense  seem  to  contain  also  tiliacin  while  the  glucoside  of  Phlox 
paniculata  differs  as  well  from  tiliacin  as  from  hesperidin. 
Ethereal oil  of  Daucus  Carota. — Schimmel  &  Co.  prepare  this  oil 
by  treating  the  fruit  with  high  pressure  steam.  According  to  M. 
Landsberg  (Arch.  Pharm.,  1890,  ccxxviii,  85)  the  oil  is  yellow,  of  a 
pleasant  carrot  odor  and  pungent  taste,  is  acid  to  litmus  paper  and 
easily  soluble  in  alcohol,  ether,  glacial  acetic  acid,  chloroform,  etc. 
Sp.  gr.  at  200  C.  0  8829.  The  chemical  constituents  are  (1)  a  terpene 
boiling  at  1 59— 161 0  C,  and  belonging  to  the  pinene  group  (Wal- 
lach),  and  (2)  an  oxygenated  portion  C10H18O  closely  allied  to  cineol 
and  can  be  regarded  as  a  monohydrated  terpene.  Acetic  acid  was 
noticed  in  small  quantity. 
Ethereal  oil  of  Mas  soy  bark. — Schimmel  &  Co.  put  on  the  market 
an  oil  under  the  above  name,  which  is  obtained  from  a  lauraceous 
plant  of  Ne.v  Guinea.  The  oil  is  limpid,  perfectly  clear,  yellow  and 
resembles  cloves  in  odor.  According  to  E.  F.  R.  Way  (Arch. 
Pharm.,  1890,  ccxxviii,  p.  22)  the  composition  is  as  follows  :  (1)  a 
terpene  C10H16,  named  massoyene  which  does  not  correspond  to  any 
hydrocarbon  described  by  Wallach ;  (2)  safrol,  by  oxidation  with 
KMnO^  the  odor  of  piperonal  was  distinctly  noticed  ;  (3)  eugenol  of 
the  formula  C6H3(CH2CH  =  CH2)  0CH3,  OH;  (4)  a  small  quan- 
tity of  creasote-like  bodies.
