Qualitative and Quantitative Phytochemical Analysis of Aloe barbadensis Miller Leaf Extracts

Abstract

The medicinal, folkloric, and other uses of aloe vera cannot be over-emphasized. In this study, we qualitatively and quantitatively analysed the phytochemical composition of Aloe vera. Fresh leaves of Aloe vera were extracted by percolation method using three different solvents: ethanol, diethyl ether, and distilled water. The extracts were analysed for important phytoconstituents using conventional qualitative and quantitative methods. The results showed that alkaloids, flavonoids, glycosides, cardiac glycosides, saponins, saponin glycosides, and tannins were present, while steroids, balsam, anthraquinones, and volatile oil were not detected. The quantitative analysis indicated a high concentration of alkaloids (31.067 g/100 g), tannins (25.66 g/100 g), and saponins (10.67 g/100g) while glycosides (0.060 g/100 g) had the least concentration. The result indicates the potential health and cosmetic benefits of Aloe vera as well as its potential benefits in the food industries
