A New Method for the Assay of Bisoprolol Using Bromocresol Green
نویسندگان
چکیده
A new Vis spectrophotometric method was developed for the assay of bisoprolol in pharmaceutical preparations using bromocresol green in hydrochloric acidic medium. The reaction product showed a maximum absorbance at 402 nm proportional with the concentration of bisoprolol. The optimum conditions for the reaction were established. The developed method was validated. The method showed a good linearity in the concentration range of 7 – 80μg/mL (correlation coefficient r = 0.9998). The detection limit (LOD) was 1.78 μg/mL and the quantification limit (LOQ) was 5.41 μg/mL. The precision and the accuracy were determined; mean recovery was 100.11% in the 98.35-101.57% concentration range.

متن کاملBromocresol purple, a non-specific colour reagent for the determination of serum albumin.
The determination of serum albumin with the dye reagent bromocresol purple was investigated. We found that bromocresol purple is not a specific reagent for albumin, but that serum proteins in the alpha-, beta-, and gamma-globulin fractions also react with this dye. Similar results were obtained for bromocresol green. Furthermore there is a great difference in absorbance between human and bovine...

Three new, simple, rapid and sensitive spectrophotometric methods have been developed for the assay of mebendazole (MBD) in bulk drug, tablets and suspension. First method (method A) is based on the formation of a colored ion-pair complex (1:1 drug/dye) of MBD with bromocresol green (BCG) at pH 1.99 ± 0.01 and extraction of complex into chloroform followed by measurement of yellow ion-pair comp...

A spectrophotometric method for the assay of bisoprolol fumarate was established based on an ion pair complex formed between bisoprolol and tropaeolin 00, in acidic medium, which could be quantified after being extracted in dichloromethane, by measuring its maximum absorbance at 412 nm. The working procedure was established and the analysis method was validated. Thus, 1 mL 0.05M hydrochloric ac...
