The triterpene alcohol constituents of the non‐saponifiable lipids of two Theaceae seed oils, sasanqua and camellia oils, and two Gramineae seed oils, wheat germ and rice bran oils, were investigated. This led to the isolation and characterization of one acyclic and eight incompletely cyclized triterpene alcohols. They are camelliol A, camelliol B, camelliol C, achilleol A, helianol, isohelianol, sasanquol, graminol A [(13 R , 14 R )‐3,4‐ seco ‐25(10→9) abeo ‐8α,9β,10α‐podioda‐4,17,21‐trien‐3‐ol], and (2 Z ,6 Z ,10 Z ,14 E ,18 E )‐farnesylfarnesol. Two other compounds isolated were characterized as (2 Z ,6 Z ,10 E ,14 E )‐geranylfarnesol, a sesterterpene alcohol, and phytol, a diterpene alcohol. Graminol A and (2 Z ,6 Z ,10 E ,14 E )‐geranylfarnesol are considered to be new natural products.
