A  October ,Pi9wT*}     Examination  of  Lippia  Scaberrima.  453 
resolved  principally  into  two  fractions,  boiling  at  145- 1 75 0  and 
200-2300  C./20  mm.  respectively.  Both  these  fractions  were  light 
yellow,  fairly  mobile  oils,  possessing  a  somewhat  fragrant  odor. 
The  one  of  lower  boiling  point  (145-1750  C./20  mm.)  gave  on  anal- 
ysis the  following  result: 
o  n  30  gave  0-3274  C02  and  o  noo  H20.    C  =  79  0;  H  =  10  8. 
CuH180  requires  C  =  79-5  ;  H  =  io-8  per  cent. 
A  portion  of  this  product  was  boiled  with  acetic  anhydride,  the 
product  distilled,  and  then  analyzed. 
0-1054  gave  0-2970  C02and  0-0968  H20.  C  =  76-9;  H  =  10  2. 
CnH17  —  O  —  CO  —  CH3  requires  C  =  75  0 ;  H  =  9  6  per  cent. 
The  iodine  value  of  the  acetylated  product  was  then  determined. 
0-2349  absorbed  0-1723  iodine.  Iodine  value  =  73-4. 
CnH17  —  O  —  CO  —  CH3,  containing  one  double  linking,  would 
have  an  iodine  value  of  122-1. 
The  fraction  boiling  at  200-2300  C./  20  mm.  gave  on  analysis  the 
following  result : 
0-0854  gave  0  2513  C02  and  0-0916  H20.    C  =  80-3  ;  H  =  11-9. 
C14H240  requires  C  =  8o-8  ;  H  =  115  per  cent. 
It  was  then  acetylated,  and  the  product  distilled  and  analyzed. 
0-1057  gave  0  3006  C02  and  0-1041  H20.    C  =  77*6;  H  =  109. 
C14H23  —  O  —  CO  —  CH3  requires  C  =  76-8  ;  H  ==  10  4  per  cent. 
0  2045  absorbed  0-1991  iodine.    Iodine  value  =  97-4. 
C14H23  —  O  —  CO  —  CH3,  containing  one  double  linking,  requires 
an  iodine  value  of  ioi-6.  « 
These  results  show  that  the  above  fractions  did  not  consist  of  pure 
substances,  but  evidently  contained  alcohols  which  appear  to  possess 
the  general  formula  CnH2n_40,  with  one  double  linking.  The 
viscid  substances  which  usually  accompany  the  phytosterols  in  small 
amount  possess  an  odor  resembling  that  of  the  above-mentioned 
alcohols,  and  they  are  probably  similar  in  character.  The  amount 
of  these  fractions  was  too  small  to  permit  of  their  further  purifica- 
tion. 
Fraction  265-3J00  C./i$  mm. — This  fraction  was  by  far  the 
largest  obtained.  It  almost  all  passed  over  above  2900  C./15  mm., 
and,  on  cooling,  solidified  completely.  It  was  crystallized  three 
times  from  ethyl  acetate,  when  a  substance  was  obtained  in  the 
form  of  silky  leaflets,  melting  at  68°  C. 
0  0757  gave  0-2356  C02  and  0-0986  H20.    C  =  84-9;  H  =  14-5. 
C31H64  requires  C  =  85-3;  11=14-7  Per  cent-
