Following oral administration of eriocitrin (75 μmol/kg in distilled water) to male Sprague-Dawley rats, Homoeriodictyol was detected in the plasma at 4.0 h post-administration, but only after treatment with β-glucuronidase/sulfatase, indicating its presence as conjugated metabolites (glucuro and/or sulfo conjugates). Free (nonconjugate) Homoeriodictyol was not detected in plasma. In urine collected for 24 h after oral administration of eriocitrin (50 μmol/kg in distilled water), both nonconjugates and conjugates of Homoeriodictyol were detected. The plasma antioxidant activity (resistance to lipid peroxidation induced by AAPH) was significantly increased at 0.5, 1.0, 2.0, and 4.0 h post-administration of eriocitrin, and the presence of Homoeriodictyol (along with other metabolites) in plasma at 4.0 h may contribute to this antioxidative activity.

| Animal Protocol |
Male Sprague-Dawley rats (5 weeks old, weighing 195-210 g) were fasted overnight, then administered eriocitrin (75 μmol/kg in distilled water) by gastric intubation. At different times (0.5, 1.0, 2.0, and 4.0 h) following administration, rats were anesthetized with ether, and blood was withdrawn from the abdominal aorta into heparinized tubes to obtain plasma.
For urine collection, rats were administered eriocitrin (50 μmol/kg in distilled water) by gastric intubation, and urine was collected for 24 h and 48 h. Plasma and urine samples were analyzed by HPLC and LC-MS for metabolites, including Homoeriodictyol. To detect conjugated forms, samples were treated with β-glucuronidase/sulfatase (5.4×10² units/mL of β-glucuronidase and 0.2×10² units/mL of sulfatase) for 20 min at 37°C before analysis. [1] |
| ADME/Pharmacokinetics |
Homoeriodictyol is a metabolite of eriocitrin detected in rat plasma at 4.0 h after oral administration, existing exclusively in conjugated (glucuronide and/or sulfate) forms, as it was not detectable without β-glucuronidase/sulfatase treatment. [1]
In urine collected for 24 h following oral administration of eriocitrin, both nonconjugate (free) and conjugate forms of Homoeriodictyol were detected. [1] Homoeriodictyol is formed by O-methylation at the 3' position of the B ring of eriodictyol, which is the aglycone of eriocitrin, and this methylation likely occurs in the liver. [1] The total absorption ratio of eriocitrin (calculated from the sum of all detected metabolites, including Homoeriodictyol, in renal excreted urine) was 5.68% ± 0.32. [1] |

| Additional Infomation |
High-sweet charantin is a trihydroxyflavanone composed of 3'-methoxyflavanones, with the three hydroxyl substituents located at positions 4', 5, and 7. It is a metabolite and flavoring agent. It is both a monomethoxyflavanone and a trihydroxyflavanone, belonging to the 3'-methoxyflavanone and 4'-hydroxyflavanone classes. Functionally, it is related to sweet charantin. High-sweet charantin has been reported to be found in Sichuan poplar, chili peppers, and other organisms with relevant data.
Homoeriodictyol is one of the main eriocitrin metabolites in vivo, together with eriodictyol and hesperetin. The o-dihydroxy structure at the 3' and 4' positions in the B ring of eriodictyol is considered important for antioxidative activity; O-methylation (forming Homoeriodictyol and hesperetin) seems to be responsible for the loss of antioxidant activity. [1] The metabolic pathway of eriocitrin involves intestinal bacterial hydrolysis to eriodictyol, followed by absorption and subsequent methylation in the liver to produce Homoeriodictyol (3'-O-methyleriodictyol) and hesperetin (4'-O-methyleriodictyol).
