Plant extracts of Cissus hastata, indigenously known as Semperai, have been used as an effective traditional remedy against coughs. Recently, the leaf extract was potentially shown to have anti-hemorrhoid activity, although there is a lack of scientific data due to its folklore usage. Hence, the therapeutic properties of the phytochemicals and metabolites of Semperai remain elusive. Therefore, this study aims to determine the total phenolic content and phytochemical compounds of the plant leaf extract. Total phenolic content and antioxidant activity were determined by the Folin–Ciocalteau method and the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method, respectively. Phytochemical compounds present in the leaf methanol extract were analyzed by a qualitative method. Results showed the extract comprised a total of 21.3 mg GAE/g of phenolic content with reference to gallic acid. The antioxidant activity was almost absence with an IC50 of 7.80 μg/mL when compared to trolox and gallic acid. Presence of the red to orange precipitate in reference to gallic acid indicate alkaloid content, while the appearance of black-blue/green color in reference to gallic acid are referred to as tannins. The steroids were represented by an upper red layer and a yellowish sulfuric acid with green fluorescence in comparison to cholesterol. Nonetheless, saponin was not detected in the extract, as indicated by the absence of the persisting foam in the test solution when compared with sodium dodecyl sulphate. In conclusion, despite not having an antioxidant property, the methanol extract of Semperai comprised a fair amount of phenolic compounds, including tannins, alkaloids, and steroids, which, potentially, are highly anti-inflammatory towards hemorrhoids.
