Opis:: The leaf extracts of two medicinal plants Asystasia gangetica (L) and Newboulia leavis (p. Beauv) were assessed for anti-snake venom activity in vivo using mice. The result of the phytochemical analysis revealed that the two plants contain flavonoids, glycosides, saponins, tannins and alkaloids. The methanolic extracts of the two plants A. gangetica (L) and N. leavis (p. Beauv) significantly (p< 0.05) neutralized the Naja melanoleuca venom-induced lethality activity in the mice. The extracts (flavonoids, tannins and saponins) of the two plants also showed significant (p<0.05) neutralization of the venom–induced lethality activity in mice. The work confirmed that Asystasia gangetica and Newbouldia leavis possess significant anti-venom activity and can therefore be used in the treatment of snake bites.

Opis:: The main objective of this research is to determine the content of metals (Ca, Cu, Fe, Mg and Zn) and total phenols in different plant extracts of Moringa oleifera, Cassia tora, Ocimum gratissimum, Vernonia baldwinii and Telfairia occidentalis. Content were determined using Atomic Absorption Spectroscopy. The result indicate that Moringa oleifera plant extracts range from 0.25 ±0.00 to 6.13 ±0.30 mg/kg, Cassia tora plant extracts - 0.17 ±0.03 to 7.48 ±0.06 mg/kg, Ocimum gratissimum plant extracts - 0.18 ±0.00 to 5.43 ±0.12 mg/kg, Vernonia baldwinii and Telfairia occidentalis plant extracts - 0.21 ±0.03 to 7.86 ±0.12 mg/kg and 0.17 ±0.00 to 4.52 ±0.06 mg/kg, respectively. The results also revealed a lower abundance of heavy metals. The total phenolic content was determined using the modified Folin-Ciocalteu method. Herein, the phenolic content in Moringa oleifera was 8.50 ±1.23 mg Garlic Acid Equivalent g-1 (mg GAE g-1), Cassia tora - 30.00 ±0.00 mg GAE g-1, Ocimum gratissimum - 45.00 ±1.41 mg GAE g-1 , Vernonia baldwinii - 49.00 ±1.14 mg GAE g-1 and Telfairia occidentalis - 46.6 7 ±0.27 mg GAE g-1. We found the lowest total phenol content in Moringa oleifera. This also possessed high chelating activity. In contrast, Vernonia baldwinii contained the highest total phenol content, but had low chelating activity. The plant extracts with high levels of phenolic compounds exhibited good antioxidant activity.
