Vegetable oil is one of the foods rich in plant phytosterol, both soybean oil and corn oil have higher content of phytosterol. Phytosterols is white powders which can be soluble in fats in ester form. There are three types of phytosterols: 4-methylsterol, 4-methylsterol and 4,4'-dimethylsterol. Non-methylsterols mainly include beta-sitosterol, stigmasterol, campesterol and rapeseed sterol, etc. The structure of phytosterols mainly found in the seeds of plants is basically similar to that of animal sterols. The only difference is the number of methyl groups attached to position c-4 and the difference in the side chain at position c-11. These side chains with slight difference in the above causes it to have different physiological functions.

Applications: Cholesterol reduction, cough suppression, expectorant, and tumor suppression and repair tissue inhibition. It is used for type II hyperlipidemia, atherosclerosis, and chronic bronchitis, but also for early cervical cancer and skin ulcers. Gastrointestinal reactions such as loss of appetite, diarrhea and gastrointestinal pain can occur at large doses. Ulcers caused by osteomyelitis should not be used before the original onset is not cured. Lower leg ulcers with varicose veins in the lower limbs must be treated simultaneously.
Studies used as lipid-lowering drugs, medical materials and health food; β-sterol used to supplement mouse diet found an obvious effect on body quality accumulation.
Effect of Phytosterol:
1. Phytosterol are well aerobic and can act as food additives such as antioxidants, nutritional additives.
2. Can be used as a raw material for animal growth agent to promote animal growth and improve animal health.
3. Phytosterol can inhibit the absorption of cholesterol, promote cholesterol degradation and metabolism, and inhibit cholesterol biochemical synthesis.
4. promoting wound healing, make muscle proliferation and enhance capillary circulation.
5. Have very high permeability to the skin, can maintain the skin surface water, promote skin metabolism, prevent sun drying erythema, skin aging.
