<dcterms:abstract>Brown rice, an important material of whole-grain food, is increasingly popular for its&#xd;
health benefits. Thus, seven varieties of brown rice from southern China were analyzed in this study,&#xd;
concerning the free and bound phenolic compounds in the extract. The phenolic profiles of different&#xd;
brown rice were obtained and compared by the combination of HPLC and LC-MS analysis, in which&#xd;
eleven phenolic acids were identified. It was indicated that the total phenolic contents of different&#xd;
brown rice varied from 92.32 to 196.54 mg of gallic acid equivalent (GAE)/100 g DW. Ferulic acid and&#xd;
p-coumaric acid, free and bound, dominated within the phenolic acids. To be mentioned, the total&#xd;
phenols of Luotiangongmi (a kind of red rice) were significantly higher than the other six varieties.&#xd;
The high phenolic content of brown rice can further guide us to explore the functional properties of&#xd;
the crops.</dcterms:abstract>
