“…However, the leaf extract showed higher antibacterial and antifungal activity against the microbes than the stem extract. This according to Hassan et al (2009) could be attributed to presence of higher bioactive compounds in leaf extracts. Furthermore, the sensitivity and susceptibility of the microbes to the plant extracts varied.…”

Aqueous and ethanolic leaf and stem extracts of Gnetum africanum were investigated for the presence and composition of these phytochemicals (alkaloid, flavonoid, tannin, phenol, saponin, sterol, terpenoid and cyanogenic glycoside) and their antifungal and antibacterial activities at various concentrations against some selected clinical microbes (fungal strains: Candida albicans and Aspergillus niger and bacterial strains: Staphylococcus aureus, Escherichia coli and Salmonella typhi) using standard methods. Analysis of variance (ANOVA) was employed in data analysis. Qualitative and percent quantitative phytochemical results showed that both the aqueous and ethanolic leaf and stem extracts contained these phytochemicals assayed but at varied quantities except cyanogenic glycoside. Antifungal and antibacterial studies indicated that both the aqueous and ethanolic leaf and stem extracts of Gnetum africanum inhibited the growth of the microbes but at varied levels and the inhibition was extracts concentration dependent. However, both the aqueous and ethanolic leaf and stem extracts showed no inhibition against the bacterial strains at 50 mg mLG 1 of the extracts. The extracts showed higher inhibition against the fungal strains than the bacterial strains. Inhibitory effect of the leaf extract was significantly higher than those of the stem extract. The ethanol extract showed significantly higher inhibition than the aqueous extract. Antibiotics had a better activity when compared to the extracts at the same concentration. Gnetum africanum extracts were biostatic in their action, when purified will give a product with higher activity. The data obtained from the study indicated that the plant possessed antifungal and antibacterial potentials especially antifungal and could be used as natural fungicides.

Qualitative and percent quantitative phytochemical results showed that both the aqueous and ethanolic leaf and stem extracts contained these phytochemicals assayed but in varied quantities except cyanogenic glycoside. Antimicrobial studies indicated that both the aqueous and ethanolic leaf and stem extracts of Gongronema latifolium inhibited the growth of the microbes but at varied levels and the inhibition was extracts concentration dependent. The ethanolic extract showed significantly higher inhibition than the aqueous extract in all concentrations except at 150 mg mLG 1 where the reverse was the case. The extracts showed higher inhibition against the fungal strains than the bacterial strains. Inhibitory effect of the leaf extract was significantly higher than those of the stem extract. Antibiotics had a better activity when compared to the extracts at the same concentration. Gongronema latifolium extracts were biostatic in their action, when purified will give a product with higher activity. The data obtained from the study indicated that the plant possessed antimicrobial properties especially antifungal and could be used in the treatment of bacterial and fungal infections but more especially the latter.

“…From the study, the leaf showed significantly higher inhibitory effects against the tested pathogens when compared to root and stem extracts. According to [21] this could be attributed to presence of higher bioactive compounds in the leaf extract than in the stem and root extracts. The result revealed inhibitory effect of the extracts against the pathogens to be in direct proportion to the concentration of the extracts (i.e.…”

Ethanolic leaf, stem and root extracts of Vitex chrysocarpa were investigated for the presence and composition of these phytochemicals (alkaloid, flavonoid, phenol, tannin, sterol, hydrogen cyanide, anthraquinone, saponin and terpenoid) using standard techniques. Their antimicrobial activities at different concentration against some selected clinical pathogens (bacterial strains Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa, Fungal strain Aspergilus niger) were also studied using agar diffusion method. Minimum Inhibitory Concentration against the organisms was also evaluated. Analysis of Variance (ANOVA) was employed in data analysis. Qualitative and percent quantitative phytochemical results showed that Ethanolic leaf, stem and root extracts contained these phytochemicals assayed but at varied quantities. Antimicrobial studies indicated that the ethanolic leaf, root and stem extracts of Vitex chrysocarpa inhibited the growth of the pathogens but at varied levels and the inhibition was extracts concentration dependent. However, the extracts showed higher inhibition against the fungal strain than the bacterial strains. Inhibitory effect of the leaf extract was significantly higher than those of the stem and root extracts with minimum inhibitory concentration of 50 mg/ml for S. aureus and E. coli, 25 mg/ml for P. aeruginosa and 12.50 mg/ml for A. niger. For the stem, the minimum inhibitory concentration is at 50 mg/ml for S. aureus and P. aeruginosa, 75 mg/ml for E. coli and 25 mg/ml for A. niger. For the root, minimum inhibitory concentration is at 75 mg/ml for S. aureus and E. coli, 25 mg/ml for P. aeruginosa and 50 mg/ml for A.niger. Antibiotic had a better activity when compared to the extracts at the same concentration. The data obtained from this study showed that the plant possessed antimicrobial properties especially antifungal and could be used in the treatment of bacterial and fungal infections but more especially the latter.
