Carrot Oil
Staniszewska and Kula (2001) analyzed the composition of a lab-prepared oil of Daucus carota L. ssp. carota that was obtained from wild carrot fl owering umbels growing in their naturalized habitat in Poland. Using a combination of GC and GC/MS, the oil was found to contain the following constituents:
alpha-thujene (0.32 percent)
alpha-pinene (40.67 percent)
camphene (1.64 percent)
sabinene (18.34 percent)
beta-pinene (2.25 percent)
myrcene (7.04 percent)
alpha;-phellandrene (0.03 percent)
alpha-terpinene (0.67 percent)
p-cymene (1.38 percent)
limonene (5.26 percent)
(Z)-beta-ocimene (3.25 percent)
(E)-beta-ocimene (0.98 percent)
gamma-terpinene (1.53 percent)
pinol + cis-sabinene hydrate (0.38 percent)
terpinolene (0.41 percent)
linalool (0.99 percent)
alpha-campholenal (0.11 percent)
trans-pinocarveol (0.03 percent)
terpinen-4-ol (4.84 percent)
myrtenal (0.02 percent)
alpha-terpineol (0.26 percent)
bornyl acetate (0.13 percent)
alpha-terpinyl acetate (0.09 percent)
neryl acetate (0.02 percent)

beta-elemene (0.20 percent)
cis-alpha-bergamotene (0.03 percent)
beta-caryophyllene (1.63 percent)
beta-gurjunene (0.06 percent)
trans-alpha-bergamotene (0.03 percent)

(E)-gamma-bisabolene (0.21 percent)
alpha-bisabolene* (0.03 percent)
palustrol (0.02 percent)
alpha-bisabolol (0.11 percent)
hexahydrofarnesyl acetone (0.01 percent)
hexadecanoic acid (0.04 percent)
tricosane (0.05 percent)
tetracosane (0.02 percent)
