Phenolic sulfonate derivative based on cinnamamide structure as well as preparation method and application of phenolic sulfonate derivative

The invention discloses a phenolic sulfonate derivative based on a cinnamamide structure as well as a preparation method and application of the phenolic sulfonate derivative. According to the source of the spartinin and the effect of the spartinin in spartina resource utilization, the spartinin is named as a spartinin B series and a spartinin D series. The structural formula of the phenolic sulfonate derivative based on the cinnamamide structure is shown in the formula (I), in the formula (I), R1 is selected from substituted or non-substituted phenyl, and R2 is selected from H or methoxyl. The compound provided by the invention has xanthine oxidase inhibitory activity, and can be used for preparing drugs for treating and/or preventing hyperuricemia. The upstream preparation raw material p-coumaric acid or ferulic acid of the compound can be obtained by a natural extraction method, and resource utilization of spartina alterniflora can be realized. 本发明公开了一类基于肉桂酰胺结构的磺酸酚酯衍生物及其制备方法和应用。根据其来源及在米草资源化利用中的作用，命名为米草素B系列和
