OBJECTIVE To investigate the in vitro antioxidant activity of different fractions (R1, R2 and R3) obtained from pet ether extract of black pepper fruits (Piper nigrum Linn.) MATERIALS AND METHODS The fractions R1, R2 and R3 were eluted from pet ether and ethyl acetate in the ratio of 6:4, 5:5 and 4:6, respectively. 1,1-Diphenyl-2-picryl-hydrazyl (DPPH) radical, superoxide anion radical, nitri...

The present study was conducted to evaluate the analgesic, anti-inflammatory and antipyretic activities of Thymus serphyllum Linn. in mice. Anti-inflammatory activity was evaluated by carrageenan and egg albumin induced paw edema in mice, while analgesic activity was assessed using formalin induced paw licking and acetic acid induced abdominal writhing in mice. For determination of antipyretic ...

With a goal of minimal application of environmentally hazardous chemical insecticides, the larvicidal activity of cypermethrin was studied alone and in combination with the root extract of Solanum xanthocarpum against anopheline larvae. Petroleum ether extract was observed to be the most toxic, with LC,, of 1.41 and 0.93 ppm and LC90 of 16.94 and 8.48 ppm at 24 and 48 hours after application, r...

The current study was to investigate the antibacterial, antifungal activity and phytochemical analysis of the various leaf and stem extracts of A.alata. Methanol, ethanol, chloroform, acetone and petroleum ether extracts of shade dried plant leaf and stem of A.alata were tested for antibacterial, antifungal and phytochemical screening. Th...

In this study, the total 80% of MeOH extract and also petroleum ether, CHCl3, EtOAc, n-BuOH, and the remaining MeOH fractions obtained by solvent-solvent fractionation of the whole flowering samples of Centaurea bruguierana (DC.) Hand.-Mzt. ssp. belangerana (DC.) Bornm. (Asteraceae), namely "Baad-Avard", collected from Borazjan in Bushehr Province (Bushehr, Iran) were investigated for larvicida...

BACKGROUND Trichomonas vaginalis is considered one of the main causes of vulvovaginitis in women. Metronidazole with vast side effects is now the drug of choice for treatment of this infection. In an attempt to find an alternative drug, the effect of Eucalyptus camaldulensis on this parasite was shown in previous studies. In this investigation, the effect of different extracts of this plant on ...

The methanol, ethanol and petroleum ether soluble crude and fractions extract of Gliricidia sepium and Spathodea campanulata leaf were examined for antibacterial activities, phytochemicals and possible sources of antioxidant. The antibacterial activity of the crude and fractions were carried out against nine clinical bacteria isolates using the agar well and disc diffusion methods respectively....
