The photoreaction of the antioxidant ellagic acid () elicits a drastic coloration in solution from colorless to yellow in aerated tetrahydrofuran, which appears as a new absorption band at 405 nm. Analysis of the X-ray crystal structure suggests that the photo-oxidation product of is a multiple cleavage π-structure () that results from the interaction of with singlet oxygen followed by sequential cleavage and rearrangement steps.
抗氧化剂鞣花酸（）在充气的四氢呋喃溶液中的光反应会引发溶液从无色到黄色的剧烈变色，这在405nm处表现为一个新的吸收带。X射线晶体结构分析表明，的光氧化产物是一种多重裂解π结构（），它是由与单线态氧相互作用，随后经过连续的裂解和重排步骤而产生的。
