Pharmacological profiles, namely caffeine, total phenolic content (TPC), total flavonoid content (TFC), and DPPH radical scavenging activity of different green tea brands of Pakistan, were analyzed. Caffeine yields varied for the other brands, but 100 ml of ethyl acetate always extracted the highest concentration. For TPC and TFC levels, JEHAN Premium Tea showed the highest values, suggesting significantly better antioxidant potential than other brands, such as Shan Tea, with low phenolic and flavonoid contents. Similarly, the DPPH radical scavenging activity of JEHAN Premium Tea remained highest in all evaluated solvents, indicating it possesses durable antioxidant potential. Our results are important to know about the chemistry and health relevance of green teas prevailing within the Pakistani market. JEHAN Premium Tea is better for consumers who want higher antioxidant beverages. Further research should investigate health outcomes and consumer preferences based on various green tea compositions.
