The quality control of herbal drugs is a critical aspect of ensuring their safety, efficacy and reliability. The complex composition of herbal products, influenced by environmental, genetic and processing factors, necessitates robust analytical approaches. This review highlights recent advancements (2020-2024) in quantitative and qualitative methods for herbal drug quality control. Quantitative methods, such as HPLC, GC, and NMR spectroscopy, focus on the precise measurement of bioactive compounds, ensuring batch-to-batch consistency. Complementary to these are qualitative methods, including DNA barcoding, TLC and phytochemical screening, which authenticate botanical sources and detect adulterants. The integration of these methodologies provides a comprehensive framework for quality assessment, addressing both compositional consistency and authenticity. Despite advancements, challenges such as variability in raw materials and the lack of universal standards persist. This review underscores the need for interdisciplinary collaboration to overcome these challenges and standardize quality control practices globally. By leveraging recent technological innovations, the pharmaceutical industry and regulatory bodies can ensure the safety and efficacy of herbal medicines, fostering consumer confidence and adherence to regulatory requirements.

Aim: The plant Michelia champaca L. plant is a very rich source of phytoconstituents with medicinal properties. The aim of the study is to analyze the chemical constituents present in the crude extract responsible for various pharmacological actions. Materials and Methods: The aerial parts of the plant Extracted with ethanol and subjected to LC-MS and HPTLC analysis by using Water Q-TOF micro coupled with 2795 HPLC and CAMAG TLC SCANNER -3. Results: LC-MS analysis showed the various peaks with low and high molecular weights indicating the presence of various phytochemicals. The compounds identified in the ethanol extract include parthenolides, quercetin, stigmasterol, sitosterol, and liriodenine and some unknown compounds by comparison with the SDBS database. HPTLC of the ethanol extract showed the Rf value of five compounds, were found to be more prominent. 0.15, 0.3, 0.45, 0.6, 0.75. identified by comparison with HPTLC - derived database. Conclusion: The compounds identified by LC-MS and HPTLC of the ethanol extract of the aerial plant Michelia champaca Linn. may be responsible for its various pharmacological activities, and hence this plant can be used in the treatment of various ailments.
