California Lomatiums, Part VII. Analysis of the essential oils of Lomatium nevadense (Watson) J. Coulter et Rose var. Parishii (J. Coulter et Rose) Jepson. Isolation of trans-dauc-8-en-11-ol, a new sesquiterpene alcohol and naturally occurring 2 ', 3 ',3 '-trimethyl-2 ',3 '-dihydroangelicin

The essential oil from the fruits of Lomatium, nevadense var. parishii showed beta-phellandrene/limonene, (Z)-beta-ocimene, (E)-beta-ocimene,gamma-terpenene, beta-caryophyllene, germacrene D, bicyclogermacrene, and (E)-sesquilavandulol to constitute more than 3% each of the oil. With the addition of (E)-2-hexenal, (Z)-3-hexenol and palmitic acid, the stem and leaf oil had similar composition. A new sesquiterpene alcohol, trans-dauc-8-en-11-ol along with naturally occurring 2',3',3'-trimethyl-2',3'-dihydroangelicin were isolated. (Z)-Falcarinol made up 48.5% of the root oil.
