Abstract

To determine the in vitro antioxidant activity and to investigate the possible antinociceptive and antiinflammatory effects of the ethanol extract of Crataegus orientalis leaves. The medicinal use of extracts prepared from the leaves, flowers, and fruits of Crataegus (hawthorn) dates back to ancient times. It has been proposed that its antioxidant constituents account for these beneficial therapeutic effects. Materials and methods: To evaluate these effects, the hot-plate, tail-immersion, writhing, and carrageenan-induced edema tests were used. Moreover, the antioxidant activity of the extract was determined using the 2,2-diphenyl-1-picrylhydrazyl and b-carotene-linoleic acid assay systems. In the tests that were used to determine antinociceptive and antiinflammatory effects, the extract was administered in dose ranges of 50, 100, and 200 mg/kg, intraperitoneally. Results: In the hot-plate test, the doses of 100 and 200 mg/kg exerted significant antinociceptive effects. In the tail-immersion test, antinociceptive effects were significant in all of the doses. In the writhing test, as the dose increased, a significant decrease in the writhing responses was observed. The antiinflammatory test results showed a dose-dependent antiinflammatory activity. In vivo tests also showed the extract as possessing antioxidant activity. Conclusion: According to the experimental findings, the ethanol extract of C. orientalis displays remarkable antinociceptive, antiinflammatory, and antioxidant activities.

Özet

Amaç: Crataegus (alıç) bitkisinin türlerinin yaprak, çiçek ve meyvelerinden hazırlanan ekstrelerinin ilaç olarakkullanımı çok eski zamanlara dayanmaktadır. Alıcın yararlı terapötik etkilerinin antioksidan içeriğinden kaynaklandığıileri sürülmektedir. Bu çalışmada Crataegus orientalis yapraklarının etanol ekstresinin in vitro antioksidan aktivitesininbelirlenmesi ve olası antinosiseptif, ve antiinfl amatuvar etkilerinin araştırılması amaçlanmıştır.Yöntem ve gereç: Ekstrenin bu etkilerinin değerlendirilmesi için hot-plate, tail-immersion, kıvranma ve karragenin ileindüklenen pençe ödem testleri kullanılmıştır. Ekstrenin antioksidan aktivitesi 2,2-difenil-1-pikrilhidrazil ve β-karotenlinoleik asit sistemi kullanılarak tayin edilmiştir. Antinosiseptif ve antiinfl amatuvar etkilerin belirlenmesi için uygulanantestlerde ekstrenin 50, 100 ve 200 mg/kg olarak hazırlanan dozları intraperitoneal olarak verilmiştir.Bulgular: Hot-plate testinde 100 ve 200 mg/kg dozlarında antinosiseptif etkide anlamlılık gözlenmiştir. Tail-immersiontestinde tüm dozlarda görülen antinosiseptif etki kontrole göre anlamlılık göstermiştir. Kıvranma testinde ise dozarttıkça kıvranma sayılarında önemli bir düşüş görülmüştür. Antiinfl amatuvar etki testinden elde edilen sonuçlar dozabağımlı bir etkinlik göstermiştir. Yapılan in vivo testlerde ekstrenin antioksidan aktiviteye sahip olduğu görülmüştür.Sonuç: Deneylerden elde edilen bulgulara göre, C. orientalis etanol ekstresinin antinosiseptif, antiinfl amatuvar veantioksidan aktivitelerinin dikkate değer olduğu sonucuna varılmıştır.
