γ - Oryzanol is a mixture of ferulic acid esters mainly composed of triterpenoids (alkenes), which is a binding lipid between ferulic acid and plant sterols. It can be extracted from cereal oils such as rice bran oil and germ oil. The content of oryzanol in the rice bran layer is 0.3-0.5%. During the heating and pressing process of rice bran, coumarin is dissolved in the oil. Generally, the coumarin content in bran oil is about 2% to 3%. Its content varies slightly with the climate conditions of rice cultivation, rice varieties, and the process conditions for extracting oil from rice bran. Rice bran from cold regions has a higher content of vitamins than that from tropical regions; High temperature pressing and solvent extraction result in a higher content of oryzanol in crude oil compared to low-temperature pressing. Among many plant oils, such as corn germ oil, wheat germ oil, barley bran oil, rapeseed oil, etc., bran oil has the highest content of oryzanol, so most oryzanol is extracted from bran oil.

γ - Oryzanol appears as a white to off white crystalline powder, odorless, with a unique fragrance. It is soluble in various oils and fats when heated and insoluble in water. γ - Oryzanol is often used in clinical practice to improve autonomic nervous system function and endocrine regulation. In addition, it has various physiological effects such as antioxidant and anti-aging.

APPLICATION

Its physiological functions include: regulating the autonomic nervous system and promoting animal growth; Regulating and improving gastrointestinal function, preventing self synthesis of cholesterol and reducing serum cholesterol, promoting skin microvascular circulation to protect the skin, with weak steroid like effects. Guweisu can also resist hyperlipidemia and inhibit the synthesis of endogenous cholesterol in the body. Used for autonomic nervous system dysfunction, periodic neuropathy, sequelae of concussion, menopausal syndrome in women, premenstrual tension, vascular headache, gastrointestinal and cardiovascular neurosis, etc.
