 Major volatiles of intact grapefruit, sweet orange, sour orange, mandarin, lemon, lime and pummelo blossoms were linalool, β-myrcene, α-myrcene, limonene, (E)-ocimene, methyl anthranilate and indole. "In terms of total volatiles: pummelo ≫ grapefruit ≈ sweet orange > sour orange ≈ mandarin ≈ lemon-lime > Volkamer lemon > Kaffir lime. Principal component analysis of blossom volatiles demonstrated that there were three widely separated, tightly clustered groups which consisted of mandarin, lemon-lime and pummelo." \\ Major volatiles of intact grapefruit, sweet orange, sour orange, mandarin, lemon, lime and pummelo blossoms were linalool, β-myrcene, α-myrcene, limonene, (E)-ocimene, methyl anthranilate and indole.

-The main constituents of the fresh peel oil are (+)-R-limonene (60-80%), and β-pinene. Together with terpinen-4-ol this compounds are responsible for a green peel odor association. Citral and the C8-C12 alkanals (0.5-0.8%) are regarded as the character-determining components of lemon oil. [[http://www.thegoodscentscompany.com/data/rw1384461.html|(E)-α-bergamotene]] (0.4%) adds a distinct pepper note, and some esters, especially geranyl acetate (0.1-1%) and neryl acetate (0.7%), contribute with fruity notes. \\+The main constituents of the fresh peel oil are (+)-R-limonene (60-80%), and β-pinene.
