“…The volatile oil of O. gratissimum also contain phenols, particularly thymol which was earlier reported to be responsible for the antimicrobial action [11,104]. The studies of the chemical composition of a related species O. suave showed that the major components of the oil are p-cymene, α-thujene, myrcene and thymol, in addition to phenols [105][106]. Therefore, these compounds may be responsible for the grains protectant and antimicrobial activities of the hexane fraction of O. gratissimum and it could serve as a potential source of pharmaceutical applications and in the control of agronomic pests.…”

Ocimum gratissimum Linn (Lamiaceae) is an herbaceous plant reputed for many medicinal and agronomic practices amongst Nigerian peasant farmers. O. gratissimum was investigated for antimicrobial activity against ten micro-organisms and for grain protectant activity against Callosobrochus maculatus. The phytocontituents of the aerial part of O. gratissimum were extracted with 95% ethanol using the percolation method. The crude ethanol extracted was further fractionated into hexane, chloroform and methanol fractions. The fractions obtained were screened for phytoconstiteunts, antimicrobial and grain protectant properties. Result showed that hexane fraction exhibited the highest antimicrobial activity against Vibrio cholera and Klebsiella pneumonia. Similarly hexane fraction also showed the highest grain protectant activity. The other extracts of the O. gratissimum did not significantly inhibit both bacterial growth and grain infestation. However, the methanol fraction contains phytocompounds such as phenolic compounds associated with antioxidant properties. The study shows that O. gratissimum extractants are potential sources of antimicrobial and preservative agents.

“…[19][20][21][22][23] It was previously reported that the oil of O. basilicum contained linalool (69%) and eugenol (10%). 23 Linalool (45.7%) and eugenol (13.4%) were reported to be the main components of the previously analyzed materials. 19 However, in this research estragole (38.226%), 1-isopropyl-4-methylenecyclohex-1-ene (11.104%), ((E)-methyl cinnamate) (6.510%), p-mentha-1(7), 8-diene (6.012%), L-Fenchone (5.793%), α-caryophyllene (4.569%), and α-pinene (3.813%) were found as major components of the essential oil of the leaves of O. basilicum having higher percentages.…”

| The present study was carried out to investigate the antibacterial activity of ethanol extract of Ocimum basilicum against infectious diarrhea caused by E. coli. Two experiments were performed in this present study; the first one is in vitro antibacterial activity of Ocimum basilicum ethanolic extract. The second experiment included study in vivo antibacterial activity of the extract after inducing diarrhea with oral pathogenic E. coli in five rats groups (eight rats of each). The results of the in vitro antibacterial study showed that E. coli was more sensitive to ethanolic extract of O.B in comparison with Gentamicin and Amikacin and it was resistant to the metronidazole, but E. coli was more sensitive to Trimethoprim/Sulfamethoxazole. Two doses of O.B extract 100, 200 mg/kg. BW were used to treat this infection for fourteen days orally. The results of the in vivo study indicated that doses of 200 mg/kg BW O.B extract and 6.85 mg/kg. BW of Trimethoprim/Sulfamethoxazole were succeeded in returning the rectal E. coli count of infected rats to normal values before inducing infection in both kinds of therapy at the first week. Food intake, water intake and body weight significantly (P < 0.05) increased in comparison with others doses or groups. From the results obtained, it could be concluded that ethanolic extract of O.B leaves at dose 200 mg/kg. BW was more effective and safe in comparison with antibacterial agent and other O.B dose, this anti-diarrheal activity of O.B ethanolic extract may be due to its constituents of secondary metabolites that are responsible for the antibacterial activity with different mechanisms of action.
