Pimenta  Oil  (Oleum  pimento). — Colorless,  yellow  or  reddish; 
eugenol-content  at  least  65  per  cent,  by  volume;  d25o  i*o33  to  i"048;1 
soluble  in  every  proportion  in  90  per  cent,  alcohol  and  also  in  2  vol. 
70  per  cent,  alcohol. 
Rose  Oil  {Oleum  roses). — Faintly  yellow;  d25o  0-855  to  0-865  ;2 
saponification  number  10  to  17  ;3  solidifying  point  between  18  and 
220.4 
Rosemary  Oil  (Oleum  rosmarini). — Colorless  or  faintly  yellow ; 
d25o  0.894  to  0-912;  aD25o  not  above  -|-  150;  the  first  10  per  cent,  of 
the  distillate  must  also  be  dextrorotatory.  Ester-content  (calculated 
as  bornyl  acetate)  at  least  5  per  cent.;  total  borneol  at  least  1 5  per 
cent.;5  soluble  in  0-5  and  more  vol.  90  per  cent,  alcohol,  and  also  in 
2  to  10  vol.  80  per  cent,  alcohol. 
Safrol  (Safrolum). — Colorless  or  faintly  yellow;  d25o  1-105  to 
i- 106  ;6  aD  ±  o°  ;  boiling  point  about  2330;  when  cooled  to  —  200 
or  below,  it  solidifies  into  a  crystalline  mass  which  does  not  melt 
below-)-  n°;  soluble  in  about  an  equal  volume  alcohol,  and  in 
about  30  volumes  70  per  cent,  alcohol. 
Sandalwood  Oil,  East  Indian  [Oleum  santali). — Faintly  yellow; 
d25o  0-965  to  0-975  >7  aT>2o°  —  16  to  —  200  ;  santalol-content  not 
below  90  per  cent.  ;8  soluble  in  5  vol.  70  per  cent,  alcohol. 
Sassafras  Oil  (Oleum  sassafras). — Yellow  or  reddish  yellow  ; 
1  The  lower  limit  of  value  is  given  too  high,  and  should  be  roi8.  Comp. 
table;  see  also  German  Report  April,  1899,  39. 
2  The  upper  limit  is  given  too  low,  and  should  be  0*867  (comp.  table). 
3  We  have  observed  in  pure  oils  saponification  numbers  between  8  5  and  19. 
4  As  upper  limit  for  the  solidifying  point  23*5°  might  be  recommended. 
5  These  requirements  cannot  be  upheld;  we  have  observed  in  good  oils  an 
ester-content  down  to  1*2  per  cent.,  and  a  total  content  of  borneol  down  to 
about  10  per  cent. 
6  The  data  of  the  specific  gravity  approximately  correspond  to  those  deter- 
mined for  150:  1*105  to  1 '107;  at  250  the  specific  gravity  varies  between  1  09S  and 
i-ioo  (comp.  table). 
7  The  upper  limit  of  value  is  too  low,  it  should  be  0-980  (comp.  table). 
8  It  is  to  be  regretted  that  the  Pharmacopoeia  bases  its  calculation  of  santalol 
on  the  formula  C15H260.  We  have  already  repeatedly  pointed  out  that  accord- 
ing to  recent  investigations  the  formula  C15H2lO  is  undoubtedly  more  correct. 
Comp.  Report,  October,  1900,  58,  and  the  April-May  Report,  p.  59.  The  lowest 
content  of  90  percent,  mentioned  above,  and  based  upon  C15H260,  corresponds 
to  a  minimum  of  89-2  per  cent,  calculated  on  C]5H240.
