This study investigated the phytochemical composition and potential antioxidant, hypoglycemic, and anti-inflammatory activities of n-hexane extracts from Vernonia amygdalina (VA), Telfairia occidentalis (TO), Gongronema latifolium (GL), and Ocimum gratissimum (OG). The extracts showed concentration-dependent increase in antioxidant activity. TO exhibited significantly higher antioxidant activity compared to the other extracts, while GL had the highest total phenolic content and OG had the highest total flavonoid content. The extracts also demonstrated hypoglycemic and anti-inflammatory effects, which could be attributed to the presence of identified phytocompounds.
This study investigated the phytochemical composition and in vitro antioxidant, hypoglycaemic and anti- inflammatory potential of n-hexane extracts of Vernonia amygdalina (VA), Telfairia occidentalis ( TO), Gongronema latifolium (GL) and Ocimum gratissimum (OG). The extracts demonstrated a concentration-dependent increase in antioxidant activity. The antioxidant activity of TO was significantly (p < 0.05) higher than the other extracts; the total phenolic content of GL was significantly (p < 0.05) higher than OG, TO and VA; and the total flavonoid content (TFC) of OG was significantly (p < 0.05) higher than the other extracts. There was no significant (p > 0.05) difference in the TFC of GL and VA, while the TFC of TO was the least. The extracts produced a concentration-dependent increase in the percentage inhibition of haemolysis in both heat- and hypotonic solution-induced haemolysis. In the heat- induced haemolysis model, the percentage inhibition of haemolysis produced by TO, GL, OG, VA and diclofenac at 200 mu g/mL concentration were 41.85, 18.26, 32.06, 15.56 and 25.49%, respectively. The extracts reduced starch digestibility and increased glucose adsorption, diffusion and uptake by yeast cells in a concentration-dependent manner. GC-MS screening of plant extracts showed the presence of five compounds in all the extracts: 2,6,6-trimethyl-bicyclo (3.1.1) heptane-2,3-diol; 9,12,15-octadecatrien-1-ol, (Z,Z,Z)-; 1-ethynyl-cyclohexanol; n-hexadecanoic acid; and phytol. Docking analysis of the major compounds common to all extracts showed a high affinity for target proteins compared to standard drugs. In conclusion, the extracts showed antioxidant, anti-inflammatory and hypoglycaemic activity, which can be linked to the identified phytocompounds.
