Research progress in polyphenol compounds in rice

Polyphenol compounds are getting more and more extensive attention because of its antioxidant activity.Rice as the staple food of human,contains a lot of polyphenol compounds. Studies have shown that cereal consumption is a kind of way to increase the source of polyphenol. Polyphenols in rice has relatively strong and widespread pharmacological actions such as the oxidation resistance,inhibiting tumor,antibacterial,anti-inflammatory,detoxification,liver protection,improving memory,anti- diabetes mellitus complication and other effects.And polyphenol also has effect on cardiovascular disease,the body's endocrine,metabolic and cell. The research progress of the polyphenol compounds of rice in domestic and foreign was reviewed.The conception of polyphenol,varieties,function and common extraction methods including organic solvent extraction,ultrasonic extraction and microwave assisted extraction method of polyphenol in rice were introduced,so as to provide a reference for the further development and utilization of rice polyphenol.
