Description

technical field

[0001] The invention discloses a high performance liquid chromatography analysis method for oryzanol, which belongs to the field of analytical chemistry. Background technique

[0002] Oryzanol is a natural mixture composed of cycloartenol-based ferulic acid esters and sterol-based ferulic acid esters. The appearance is white to light yellow crystalline powder, odorless. Oryzanol mainly exists in hair bran oil and its oil feet. In rice bran oil oryzanol, the content of cycloartenol ferulate is about 70-80%. After long-term research, researchers have found that oryzanol has a variety of physiological functions. Mainly include: lowering blood lipids, resisting the absorption of cholesterol, lowering serum cholesterol, preventing lipid oxidation and preventing cardiovascular diseases. In addition, oryzanol can also alleviate various physical disorders and autonomic nervous disorders in women after menopause, and improve the dysfunction of the base of the dience...
