Rliizouie  of  Iris  Versicolor.

and  the  solution  shaken  with  aqueous  sodium  carbonate,  when  the 
sodium  salt  of  an  acid  phthalic  ester  was  immediately  deposited. 
The  latter  was  collected,  and  washed  with  a  mixture  of  ether  and 
chloroform,  and  then  hydrolyzed  by  heating  with  alcoholic  sodium 
hydroxide.  After  removing  the  alcohol  from  the  reaction  product, 
water  was  added,  and  the  fatty  alcohol  thus  precipitated  was  col- 
lected and  crystallized  from  ethyl  acetate,  when  minute,  colorless 
needles,  melting  at  84°,  were  obtained.  This  substance  was  analyzed 
with  the  following  result : 
0.0913  gave  0.2742  COo  and  0.1154  HoO.  C  =  8i.9;  H  =  14.1 
Co^H^j^O  requires  C  =  82.3  ;  H  =  14.2  per  cent. 
The  compound  was  thus  identified  as  myricyl  alcohol. 
The  ethyl  acetate  mother-liquors,  remaining  after  the  separation 
of  the  myricyl  alcohol,  yielded  a  small  quantity  of  a  crystalline  sub- 
stance melting  at  77-78°.  The  melting  point  of  this  compound, 
together  with  the  method  of  its  isolation,  would  indicate  that  it  con- 
sisted of  ceryl  alcohol,  but  the  amount  of  substance  was  too  small 
for  an  analysis. 
The  ether-chloroform  solution  which  had  been  shaken  with 
aqueous  sodium  carbonate  to  remove  the  myricyl  acid  phthalate,  as 
above  described,  was  evaporated,  and  the  residue  heated  with  alco- 
holic sodium  hydroxide  to  remove  the  excess  of  phthalic  anhydride. 
After  evaporating  the  alcohol,  and  adding  water  to  the  residue, 
a  small  quantity  of  a  solid  was  obtained,  which  was  collected  and 
recrystallized  from  ethyl  acetate.  It  separated  from  this  solvent  in 
small,  colorless  leaflets,  melting  at  64-66°. 
0.0931  gave  0.2903  COo  and  0.1230  HoO.  €  =  85.0;  H  =  14.7 
Co^H.^g  requires  C  =  85.3  ;  H  =  14.7  per  cent. 
It  is  evident  from  the  analysis  and  the  melting  point  determina- 
tion of  this  substance  that  it  was  heptacosane. 
Isolation  of  Ipuranol,  CogHggOsCOH)^. 
The  alkaline  liquid  obtained  by  the  hydrolysis  of  the  petroleum 
extract  of  the  resin,  having  been  extracted  with  ether  to  remove 
unsaponifiable  material,  as  above  described,  was  next  acidified  with 
dilute  sulphuric  acid,  when  the  fatty  acids  were  precipitated  as  a 
dark-colored  oil.  The  mixture  was  then  shaken  with  ether,  which 
dissolved  the  fatty  acids,  leaving,  however,  a  small  quantity  (0.7 
gramme)  of  a  green  solid  undissolved.  The  latter  was  collected, 
washed  with  hot  alcohol,  and  recrystallized  from  pyridine  containing
