Abstract:
A HPLC method was developed for the determination of mangiferin in rat plasma and aqueous humor. 4-Nitrophenol was used as internal standard. Analysis was performed on a Cosmosil ODS C18 analytical column (4.6 mm x 250 mm, 5 microm) with mobile phase consisting of methanol-water (40: 60) with 2% glacial acetic acid at a flow rate of 1.0 mL x min(-1). The calibration curve of mangiferin in rat plasma and aqueous humor showed excellent linear behaviors over the investigated concentration of 0. 50-250.00 mg x L(-1) in plasma and 0.10-10.00 mg x L(-1) in aqueous humor, respectively, and the correlation coefficients were all above 0.995 4. The intra-day and inter-day precisions for all samples were measured to be below 12%. The limit of quantitation was 0.10 mg x L(-1) and low enough for the determination of mangiferin in all samples. The validated method has been successfully applied to preliminary pharmacokinetics study of mangiferin in rat plasma and aqueous humor.
