Introduction- Standardization of herbal raw materials is essential to ensure their identity, purity, safety, and quality. Syzygium cumini (L) Skeels belongs to family Myrtaceae, commonly known as Jambu, possesses significant medicinal value. However, systematic physicochemical evaluation of its flowers is limited. The present study aims to establish baseline quality control parameters for Jambu flowers. Methods- Dried flower powder of Syzygium cumini (L) Skeels was subjected to standard pharmacognostic evaluation. Physicochemical parameters including moisture content, total ash, acid-insoluble ash, water soluble ash, extractive values (water and alcohol soluble), pH, swelling index, foaming index, and fluorescence characteristics were determined according to established procedures. Results- The analysis revealed acceptable moisture content and low total ash and acid insoluble ash values, indicating minimal inorganic contamination and good quality raw material. Water-soluble extractive values were higher than alcohol soluble extractives, suggesting the predominance of polar phytoconstituents. The fluorescence analysis showed characteristic color changes under visible and ultraviolet light, supporting authentication of the crude drug. Discussion- The findings provide important baseline physicochemical standards for identification and quality assessment of Jambu flowers. These parameters can serve as reference data for quality control, standardization, and future phytochemical and pharmacological investigations of Syzygium cumini (L) Skeels.
