Phytochemical and proximate analysis of some part of the century plant (Agave americana Linn.)

The phytochemical screening and proximate analysis of the root, stem, petiole and leaves was investigated in this study. The hytochemical analysis revealed the presence of alkaloids, flavonoids, tannins, saponins, steroids, terpenoids and cardiac glycosides. The leaves are the highest in alkaloids and tannins (0.18±0.01 and 30.83±0.03) respectively. Saponin is mostly found in the petiole (25.80±0.01) while Flavonoid is found mostly in the stem (93.18±0.01). The proximate analysis revealed that the leaves contain the highest amount of protein (17.57±0.03). Carbohydrates are found mostly in the petiole and leaves (163.43±1.00 and 115.87±1.54). The stem recorded the highest amount of crude fiber (91.52±0.02). Moisture content was highest in the petiole (81.08±0.02).From the result of the phytochemical screening in Agave americana, we conclude that the plant could be very useful in the treatment of many diseases.Research has shown that the plant possesses anti-inflammatory, antibacterial, antioxidant properties.
