Aims: To evaluate the physical and chemical properties of rasam, a traditional south Indian soup. Each ingredient present in rasam are known for their medicinal value individually. Moreover, rasam has being suggested as a general control measure in the treatment of SARS-CoV-2 by Ministry of AYUSH. For formulation designing the properties of material under study is generally determined. Hence, this study was carried out to evaluate the physiochemical properties of rasam so that it would be convenient to chose a suitable dosage form.
Study Design: The physical and chemical studies was carried simultaneously in order to achieve the confirmatory results.
Place and Duration of Study: Study was performed at Parul Institute of Pharmacy & Research, Parul University, Vadodara, Gujarat, India. The study took about 45 days.
Methodology: The physical parameters evaluated were pH, viscosity, density, boiling range, surface tension, miscibility, refractive index and loss on drying. The chemical evaluation included preliminary qualitative phytochemical screening.
Results: The pH of rasam was 3.916 ±0.0133, viscosity was 0.956 cp, density was 0.993 g/mL, relative density was 0.995, boiling point was 110.3333 ± 0.333, surface tension was 107.093 N/m, refractive index was 1.37, and loss on drying was 80%. It contains several chemical constituents like alkaloids, glycosides, saponins, etc.
Conclusion: The evaluated physical and chemical properties of rasam would provide a gateway for the formulation researchers to follow-up with various dosage forms designing.
