Physicochemical, phytochemical, chromatographic, microbial, heavy metal, and aflatoxin analyses were performed. The drug displayed characteristic physicochemical properties and a distinct HPTLC fingerprint, which can serve as a reference for identity and quality assurance in future studies. Phytochemical screening revealed the presence of bioactive compounds including carbohydrates, glycosides, phenolic compounds, and tannins, which may contribute to its gastroprotective properties. Heavy metal analysis confirmed all values to be within WHO permissible limits, while aflatoxin content was also within safe limits, ensuring toxicological safety. Microbial analysis indicated overall compliance with WHO standards.
