A Sustainable Reversed-Phase HPTLC Method for the Quantitative Estimation of Hesperidin in Traditional and Ultrasound-Assisted Extracts of Different Varieties of Citrus Fruit Peels and Commercial Tablets

Abstract

Hesperidin (HSP) is a bioactive flavanone glycoside, present abundantly in the variety of citrus fruits. The environmental safety and sustainability of the reported analytical assays of HSP analysis have not been considered in the literature. Hence, a sensitive and sustainable “reversed-phase high-performance thin-layer chromatography (RP-HPTLC)” method has been developed and validated for HSP analysis in traditional (TE) and ultrasound-based (UBE) extracts of four different varieties of citrus fruit peels and its commercial tablet dosage forms. The binary combination of green solvents such as ethanol-water (50:50, v v−1) was used as the mobile phase. The detection of HSP was performed at 287 nm. The sustainable RP-HPTLC method was linear in 20–2000 ng band−1 range. The studied validation parameters, including accuracy, precision, robustness, sensitivity were acceptable for HSP analysis. The content of HSP in TE of four different varieties of citrus fruits including grapefruit peels (Citrus paradisi), mosambi peels (Citrus limetta), lemon peels (Citrus lemon), and orange peels (Citrus sinensis) was detected as 8.26, 6.94, 5.90, and 6.81% w w−1, respectively. The content of HSP in TE of commercial formulations A and B was detected as 5.31 and 5.55% w w−1, respectively. However, the content of HSP in UBE of grapefruit peels, mosambi peels, lemon peels, and orange peels was detected as 11.41, 8.86, 7.98, and 8.64% w w−1, respectively. The content of HSP in UBE of commercial formulations A and B was detected as 6.72 and 6.92% w w−1, respectively. The greenness score of the sustainable RP-HPTLC method was predicted as 0.83 using analytical GREEnness (AGREE) metric approach, indicated the excellent greenness profile of the RP-HPTLC method. UBE procedure for HSP was superior over its TE procedure. These observations and results suggested that the present RP-HPTLC method can be successfully used for the quantitative estimation of HSP in the variety of citrus fruit peels and its commercial formulations. In addition, this method is simple, rapid, precise, accurate, and economical compared to the reported analytical methods of HSP analysis. It is also safe and sustainable method due to the use of ethanol-water solvents systems, as both the solvents are green solvents compared to the solvents used in reported analytical methods of HSP analysis.

Portable Microelectrochemical Sensors for Rapid and Sensitive Determination of Hesperidin in Citrus reticulate ‘Chachi’ Peel

“…Efficient and accurate analytical methods for rapid and sensitive detection of hesperidin content in such an agricultural product, therefore, continue to be a topic of interest. Although separation-based analytical methods such as chromatography enable highly sensitive and selective hesperidin detection [ 8 , 9 , 10 ], these methods are often time-consuming and require complex procedures and costly equipment.…”

Rapid, Highly-Sensitive and Ecologically Greener Reversed-Phase/Normal-Phase HPTLC Technique with Univariate Calibration for the Determination of Trans-Resveratrol

“…Unfortunately, the greener profile of literature pharmaceutical assays was not assessed and hence not reported for any pharmaceutical assay. Greener HPTLC methods for the determination of various natural antioxidants such as cinnamaldehyde, eugenol, hesperidin, piperine, pterostilbene and thymoquinone have been reported in literature [43,[51][52][53][54]. However, greener HPTLC methods have not been reported for the determination of TRV.…”
