Aim: The present study aim was to analyze quantitatively and qualitatively the phytochemicals as well as to investigate the physicochemical and phytochemical screening of Convolvulus pluricaulis and its chloroform and ethanol extracts. Materials and Methods: In this, the physicochemical evaluation; ash values, namely total ash, acid-insoluble ash, water-soluble ash, and sulfated ash; extractive values, namely alcohol soluble extractive value, water-soluble extractive, and chloroform soluble extractive value; and loss on drying were determined. Preliminary phytochemical screening was done for the presence of carbohydrates, proteins, amino acids, glycosides, alkaloids, phytosteroids, flavonoids, saponins, tannins, and phenolic compounds, and total phenolic content was estimated by Folin–Ciocalteu method, and total flavonoid content was measured with the aluminum chloride colorimetric assay. Results: In results, it was found that the seed containing various phytochemicals were present in its ethanol and chloroform extracts. The total phenolic content in the ethanol and chloroform extracts was found 13.7 ± 0.4187 and 7.367 ± 0.2987 mg of gallic acid equivalent weight/g of extract, respectively, and the concentration of flavonoids in plant ethanol and chloroform extracts of Cassia hirsuta was found 114.6 ± 13.33 and 99.56 ± 11.6 mg of quercetin equivalent weight/g of extract, respectively. Conclusion: The present study concludes that the C. pluricaulis has the potential to act as a source of useful drugs because of the presence of various phytochemical constituents and high concentration of phenolic and flavonoid compounds.
