Title : Novel chromogenic method as a sensitive technique in estimating analytes
Abstract:
To develop and validate a simple and sensitive UV spectrophotometric method for Quantification of Hesperidin in bulk and Ayurveda formulation including plant extracts using chromogenic compound Gibb’s reagent (2, 6-Dichloro quinone 4-Chloroimide). Chromogenic method was developed in visible region by using GIBBS Reagent. Hesperidin reacts with Gibb’s reagent and 0.01N sodium hydroxide solution (Adjusted to pH 9 with dilute HCL) to produce blue colour complex.
The reaction between a chromogenic reagent and a drug is often specific to certain functional groups or chemical structures, allowing for selective detection and measurement. Gibb’s reagent chiefly utilized for the identification and determination of phenols, unsubstitued and p-alkoxy phenols. which is measured at 500–670nm. Hesperidin is a category of bioflavonoid (Flavonoid-7-o-glycosides), is isolated from citrus fruits. It is used for blood vessel conditions such as hemorrhoids, varicose veins.
For the spectrometric analysis of Hesperidin using an ELICO SL210 UV-Visible spectrophotometer with spectral treats software in accordance with International Council for Harmonization (ICH) guidelines Q2(R1), the 613nm wavelength absorbance was considered the primary maxima given improved reproducibility for further dilutions at that wavelength. The method was then validated using validation parameters such as linearity, range, precision, accuracy, ruggedness and robustness as stipulated in ICH guidelines. Linearity was well demonstrated for a concentration series of 2μg/ml to 40μg/ml, with a linear regression coefficient (R2) of 0.9999 observed. The %RSD of the precision was observed to be in limits <2%. Accuracy was found to be 98-99% within limits. LOD and LOQ were found to be 0.21318µg/ml and 0.64601µg/ml respectively. The Liquid-Liquid extraction method was used to design, validate, and expand the improved procedure to biological material.
