Composition
The following table lists a typical fatty acid composition of grape seed oil:
| Acid | Type | Percentage |
|---|---|---|
| Linoleic acid | ω−6 unsaturated | 69.6% |
| Oleic acid | ω−9 unsaturated | 15.8% |
| Palmitic acid (Hexadecanoic acid) |
Saturated | 7% |
| Stearic acid (Octadecanoic acid) |
Saturated | 4% |
| Alpha-linolenic acid | ω−3 unsaturated | 0.1% |
| Palmitoleic acid (9-Hexadecenoic acid) |
ω−7 unsaturated | less than 1% |
Grape seed oil also contains 0.8 to 1.5% unsaponifiables rich in phenols (tocopherols) and steroids (campesterol, beta-sitosterol, stigmasterol). Grapeseed oil contains small amounts of vitamin E, but safflower oil, cottonseed oil, or rice bran oil contain greater amounts.

Famous quotes containing the word composition:
“Modern Western thought will pass into history and be incorporated in it, will have its influence and its place, just as our body will pass into the composition of grass, of sheep, of cutlets, and of men. We do not like that kind of immortality, but what is to be done about it?”
—Alexander Herzen (1812–1870)
“It is my PRIDE, my damn’d, native, unconquerable Pride, that plunges me into Distraction. You must know that 19-20th of my Composition is Pride. I must either live a Slave, a Servant; to have no Will of my own, no Sentiments of my own which I may freely declare as such;Mor DIE—perplexing alternative!”
—Thomas Chatterton (1752–1770)
“Give a scientist a problem and he will probably provide a solution; historians and sociologists, by contrast, can offer only opinions. Ask a dozen chemists the composition of an organic compound such as methane, and within a short time all twelve will have come up with the same solution of CH4. Ask, however, a dozen economists or sociologists to provide policies to reduce unemployment or the level of crime and twelve widely differing opinions are likely to be offered.”
—Derek Gjertsen, British scientist, author. Science and Philosophy: Past and Present, ch. 3, Penguin (1989)
