Method for the Quantification of Bioactive Compounds in Herbal Extracts

Standardization in phytomedicine depends on the development of accurate analytical techniques for measuring bioactive components in herbal extracts; quality control also depends on this progress. This work offers a complete method for exact measurement of several bioactive elements in complex herbal matrices combining high-performance liquid chromatography (HPLC) with tandem mass spectrometry (MS/MS). To increase target compound' recovery, the approach was refined utilizing many extraction procedures including maceration and ultrasound-assisted extraction. On a C18 column using gradient elution, chromatographic separation was accomplished permitting simultaneous identification of phenolic acids, alkaloids, and flavonoids. Method validation revealed outstanding accuracy (recovery spanning 95–102%), precision (RSD < 3%), and linearity (r² > 0.996). Established at 0.01-0.05 μg/mL and 0.05-0.15 μg/mL respectively, were the limits of detection and quantification. The suggested approach was effectively employed to measure bioactive markers in five medicinal plants usually used in traditional medicine. Significant differences in phytochemical profiles between many geographical sources and extraction techniques were found using principal component analysis. While supporting the scientific validation of traditional herbal medicines, this strong analytical technique offers a useful instrument for researchers and manufacturers to guarantee consistency and efficacy of herbal formulations.Keyword: Chromatography, Spectroscopy, Phytochemicals, Standardization, Metabolomics, Bioassays
