There are three primary types of plant oil, differing both the means of extracting the relevant parts of the plant, and in the nature of the resulting oil: Vegetable fats and oils were historically extracted by putting part of the plant under pressure, squeezing out the oil. Macerated oils consist of a base oil to which parts of plants are added.
It is one of the world's oldest crops, and today is commercially cultivated for vegetable oil extracted from the seeds. Plants are 30 to 150 cm (12 to 59 in) tall with globular flower heads having yellow, orange, or red flowers. Each branch will usually have from one to five flower heads containing 15 to 20 seeds per head.
Flowering canopy New leaves with flower buds Ripe fruits Seeds. Shorea robusta seed oil is an edible oil extracted from the seeds of Shorea robusta. Shorea robusta is known as the Sal tree in India. Sal is indigenous to India and occurs in two main regions separated by the Gangetic Plain, namely the northern and central Indian regions. [1]
Seeds from these plants are noted for their oil content, but little information is available on methods of extracting the oil. In most cases, the plants are grown as food, with dietary use of the oils as a byproduct of using the seeds as food. [45] Bitter gourd oil, from the seeds of Momordica charantia. High in α-Eleostearic acid. Of current ...

Canola is a variety of rapeseed. Sunflower seed: 9.91: A common cooking oil, also used to make biodiesel Peanut: 4.82: Mild-flavored cooking ...
Grape seed oil also contains 0.8 to 1.5% unsaponifiables rich in phenols (tocopherols) and steroids (campesterol, beta-sitosterol, stigmasterol). [9] Grapeseed oil contains small amounts of vitamin E, but safflower oil, cottonseed oil, or rice bran oil contain greater amounts. [10] Grapeseed oil is high in polyunsaturates and low in saturated fat.
Seeds contain 38 to 43% oil and 27 to 32% protein. [11] Over 50% of the fatty acids in cold-pressed camelina oil are polyunsaturated. The oil is also very rich in natural antioxidants, such as tocopherols, making this highly stable oil very resistant to oxidation and rancidity. [12]
Borage plant flowers. Borage seed oil is derived from the seeds of the plant, Borago officinalis (borage). [1] Borage seed oil has one of the highest amounts of γ-linolenic acid (GLA) of seed oils — higher than blackcurrant seed oil or evening primrose oil, to which it is considered similar. GLA is typically composed of about 24% of the oil.
