Phytochemical screening and chromatographic profile of the ethanolic and aqueous extract of Passiflora edulis and Vicia faba L. (Fabaceae)

Abstract

Phytochemical screening provides first hand knowledge of plants chemical constituents. Phytochemical Screening of the ethanolic extract of Passiflora edulis indicates the presence of the following phytochemicals: Cardiac Glycosides, Tannins, Flavanoids, Emodols, Anthracenosides, Alkaloids, Glycosides, Sterol and Triterpenes, Saponins, Phlobatinins. Cholesterol wasn’t detected. In contrast, phytochemical screening of the ethanolic extract of Vicia faba L. (Fabaceae) indicates the presence of all phytochemicals with the exception of Anthracenosides and Sterols and Triterpenes. The aqueous extract of both plants showed fewer phytochemicals in comparison to the ethanolic extract. For Passiflora edulis, these include Tannins, Emodols, Anthracenosides, Glycosides and Saponins, reducing sugars. For Vicia fabia, these include Tannins, Alkaloids, Glycosides, Sterol and Triterpenes and Saponins. Reducing sugars were also detected for the ethanolic extract only. The other phytochemicals weren’t detected. The selective presence of phytochemicals were also evident.
