Analysis of hesperetin enantiomers in human urine after ingestion of blood orange juice by using nano-liquid chromatography

Hesperetin (HT) is a flavanone abundantly found in citrus fruits. It has been reported that HT possesses significant antioxidant, anticancer, anti-inflammatory and analgesic activities. This explains the necessity of developing new methods more powerful and sensitive for analyzing HT in biological fluids. Taking into account the chiral nature of HT, the study of the stereospecific kinetics of in vitro and in vivo metabolism and tissue...
