The total antioxidant activity, total phenolic content and reducing power of methanol and water extracts of four lichen species, Bryoria fuscescens, Dermatocarpon intestiniformis, Peltigera rufescens and Pseudevernia furfuracea, were determined in vitro. Water and methanol extracts of P. rufescens showed the highest antioxidant activity. However, there was no correlation between antioxidant activity and total phenolic content of the extracts. Although the methanol extract of P. furfuracea had the highest total phenolic contents, it exhibited low antioxidant activity. In contrast, there was a strong correlation between reducing power and total antioxidant activity of the extracts. The highest reducing power was determined for the methanol extract of P. rufescens. 相似文献

Corianin (1) and ellagic acid 3,3'-dimethylether (2) were obtained from the methanol extract of powdered fruits of Coriaria ruscifolia. Biological screening of both compounds and of the methanol extract revealed slight antibacterial activity and cytotoxicity. 相似文献

The ethanol and methanol extracts of Arbutus unedo leaves were screened for antioxidant activity. The antioxidant activity was determined by an improved assay based on the decolorization of the radical monocation of [2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid)] (ABTS). The ethanol and methanol extract of A. unedo leaves displayed potent antioxidant activity. 相似文献

The analgesic activity of methanol extract of Cleome viscosa, given orally at the doses of 100, 200, 400 mg/kg was evaluated for its analgesic activity in mice using the acetic acid-induced writhing and the tail flick, tail clip, tail immersion methods. The extract showed promising activity in all the tests. 相似文献

Fractions prepared from the methanol extract of Buchholzia coriacea stem bark exhibited a high concentration-dependent antibacterial and antifungal activity compared to the standard antibiotics, ampicillin and tioconazole. In the brine shrimp lethality (BSL) assay, the methanol extract was found to be non-toxic with an LC(50) of 1031 microg/ml. The two main compounds present in the most active fraction were isolated and identified as lupeol and beta-sitosterol. 相似文献

The Breynia cernua leaves, stem and root barks and heart-woods extracted with petrol, dichloromethane, ethyl acetate, butanol and methanol gave fractions with varied level of antimicrobial activity. The best activity was exhibited by the methanol extract of the root bark followed by its butanol fraction. These were the only fractions exhibiting a good level of antifungal activity as compared to the standard. The dichloromethane fraction of the stem bark also demonstrated good activity. 相似文献

The antibacterial activity of methanol extracts of ten moss species and fractions prepared from 80% methanol extract of Hylocomium splendens were evaluated by disk diffusion method. Nine moss species showed antibacterial activity against Gram (+) bacteria, in particular H. splendens and its ethyl acetate fractions showed stronger activity. Enhancement of antibacterial activity against Staphylococci by UV-A light irradiation was demonstrated in the extracts of Bartramia pomiformis, Ceratodon purpureus and Neckera douglasii. 相似文献

Ethanol extract of Maytenus rigida stem bark and its fractions were assessed for antinociceptive activity in tail-flick test in rats. The activity was located in the chloroform, ethyl acetate and aq.methanol fractions. Phytochemical screening revealed that catechin was the only common class of compounds present on the ethanol extract as well as on the active fractions. 4'-Methylepigallocatechin, isolated from the ethyl acetate and aq.methanol fractions, showed antinociceptive effect in the tail-flick test (75 mg/kg; p.o.), which was reversed by the opiate antagonist naloxone (3 mg/kg; i.p.). 相似文献
