GLC area-% fatty acids with petroselinic (18:1 delta-6c) and oleic (18:1 delta-9c) acids separated.
Seed dataset (the companion dataset #15605 is the edible root and is not used).
Petroselinic acid 55.5 % (single value); the other datasets on this page report undifferentiated C18:1 and are not used.
Table 1, carrot column, read and not merged (see notes).
THE FIXED (triglyceride) OIL of carrot seed, not carrot seed essential oil and not 'carrot oil' macerated from the root. PETROSELINIC ACID (cis-6-octadecenoic, C18:1 n-12) IS 65.5-72.5 % OF THE FATTY ACIDS AND HAS NO KEY IN THIS SCHEMA; it is kept out of the oleic key because it is a different acid (double bond at carbon 6, not 9). As a result the keyed acids cover only about a third of the oil, the validator reports a low total, and the record is reference-only: no saponification value is published in any document found, and the build cannot derive one from a profile this incomplete. For orientation only: petroselinic acid has the molar mass of oleic acid, so the oil should need about as much lye as other C18 oils, but no figure is asserted here. Sources (PlantFAdb, GLC area %): 'Search for new industrial oils: XVI. Umbelliflorae-seed oils rich in petroselinic acid' (1982) - dataset #21053 (SOFA TAB_004485; oil 17.7 %): 16:0 6.1, 18:0 0.2, 18:1 delta-6 (petroselinic) 69.8, 18:1 delta-9 (oleic) 12.4, 18:2 10.6; dataset #21054 (TAB_004486; oil 18.9 %): 16:0 3.8, 18:0 1.1, petroselinic 72.5, oleic 9.9, 18:2 10.8, 18:3 0.3. 'Fatty-acid composition of lipids from edible parts and seeds of vegetables' (1984), dataset #15606 (TAB_004488; seed, oil 26.4 %): 14:0 0.1, 16:0 4.8, 16:1 1.4, 17:0 0.3, 17:1 0.5, 18:0 0.9, petroselinic 65.5, oleic 7.3, 18:1 delta-11 1.0, 18:2 16.9, 18:3 0.5, 20:0 0.3, 20:1 0.6, 22:0 0.7, 22:1 0.0. A 1981 entry (#14782, 'Structure and occurrence of unusual fatty acids in minor seed oils') gives petroselinic 55.5 % alone. Ranges span these three complete datasets; acids reported only in #15606 are stored as max; C17:0, C17:1 and cis-vaccenic (18:1 delta-11) have no key. Other PlantFAdb carrot entries (1960, 1986, 1987, 1990, 1996) give a single C18:1 figure of 62-89 % (some labelled as oleic acid) without separating petroselinic from oleic acid, so they are not used. Contradicting analysis, not merged: Rigano et al. 2025 (J. Food Sci. 90:e17661, Table 1) analysed a cold-pressed carrot seed oil and assigned the reverse - C18:1 n-12 9.83 %, C18:1 n-9 69.69 %, with 16:0 4.70, 18:0 1.38, 18:1 n-7 2.23, 18:2 8.94, 18:3 0.24, 20:0 0.33, 20:1 0.43, 22:0 0.83, 22:1 0.73, 24:0 0.32 %; either that product differs from the seed oils analysed earlier or the two C18:1 peaks were assigned the other way round - this record cannot tell which. INCI: CosIng's 'Daucus Carota Sativa Seed Oil' is described only as 'the oil obtained from the seed of the carrot', lists FRAGRANCE among its functions and carries CAS 8015-88-1, the number of carrot seed essential oil; since it cannot be confirmed as the fixed oil, inci is null.
