<jats:title>ABSTRACT</jats:title>
<jats:p>The products from the thermal reaction of chlorogenic and caffeic acids, which is a model process of roasting coffee beans, exhibited xanthine oxidase (XO) inhibitory activity. From caffeic acid, six inhibitory phenylindanes were identified, and a new phenylindane displayed the highest inhibitory activity among them. The activity of these phenylindanes may contribute to XO inhibition-related functions of roasted coffee beverages.</jats:p>
