abstract
The present study was aimed to evaluate the phytochemicals present in the different parts of some Ipomoea species which are Ipomoea aquatica, I. asarifolia, I. quamoclit, I. involucrata, I. triloba, I. acanthocarpa, and I. hederifolia (Family-Convolvulaceae). The alkaloids, flavonoids, saponins, phenols and tannins contents of the vegetative parts of these plants viz. the leaves, stems and roots were screened and compared. Result from the phytochemical analyses showed that Alkaloids, Tannins and Steroids were present in all the parts of the seven Ipomoea species except in I. quamoclit which lacked steroids in all the parts investigated. All the species investigated contained appreciable amount of alkaloids, tannins, flavonoids and saponins ranging from (14.21±0.00% - 23.28±0.13%), (1.02±0.01% - 24.15±0.14%), (0.10±0.00% - 24.02±0.01%) and (0.17±0.01% - 25.05±0.01%) respectively. The result of this research which showed the close affinity of these plants also verify that the parts of the Ipomoea species studied possessed bioactive compounds which could be exploited for medicinal purposes.
