Özet

Objectives: Salacia pallescens has folkloric anti-inflammatory claims, with little scientific investigation. Hence, the antioxidant and anti-inflammatory effects along with phytochemical components of the plant were investigated. Materials and Methods: The antioxidant property of S. pallescens leaf (SPL) methanol extract was evaluated using 1,1-diphenyl-2-picrylhydrazyl and nitric oxide inhibition assays. The anti-inflammatory property of SPL in lipopolysaccharide-stimulated RAW 264.7 macrophages was determined. The cytotoxicity of SPL was assessed in brine shrimp lethality assay (BSL) and against RAW 264.7 cells in a 3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide based assay. Gas chromatography-mass spectrometry was employed to identify SPL phytochemical compounds. Results: SPL significantly scavenged free radical generated in the antioxidant assays and inhibited nitrite production in stimulated RAW 264.7 cells. Similarly, there was a 9-fold reduction in interleukin-6 produced in RAW 264.7 cells when exposed to the highest concentration of SPL. In addition, 50% lethal concentration of SPL was 455.58±82.35 µg/mL while cyclophosphamide gave 16.3±0.15 µg/mL in BSL test. Moreover, cell viability was not affected by SPL. Sixteen compounds were identified from SPL where thymol (29.79%), 3-carene (15.97%), and p-cymene (12.19%) are the most abundant. Conclusion: Methanol extract of SPL showed antioxidant and anti-inflammatory activities by free radicals and cytokines inhibition. The activity observed may be related to the polyphenolic compounds in the plant.

Abstract

Amaç: Salacia pallescens, çok az bilimsel araştırma ile folklorik anti-inflamatuvar iddialara sahiptir. Bu nedenle bitkinin fitokimyasal bileşenleri ile birlikte antioksidan ve anti-inflamatuvar etkileri araştırılmıştır. Gereç ve Yöntemler: S. pallescens yaprağı (SPL) metanol ekstresinin antioksidan özelliği, 1,1-difenil-2-pikrilhidrazil ve nitrik oksit inhibisyon deneyleri kullanılarak değerlendirilmiştir. Lipopolisakkarit ile uyarılan RAW 264,7 makrofajlarda SPL’nin anti-inflamatuvar özelliği belirlenmiştir. SPL’nin sitotoksisitesi, tuzlu su karides ölümcül tahlilinde (BSL) ve 3-(4,5-dimetiltiyazol-2-il)-2,5-difeniltetrazolyum bromür bazlı bir tahlilde RAW 264,7 hücrelerine karşı değerlendirilmiştir. SPL fitokimyasal bileşiklerini tanımlamak için gaz kromatografisi-kütle spektrometrisi kullanılmıştır. Bulgular: SPL, antioksidan deneylerde üretilen serbest radikali önemli ölçüde uzaklaştırmış ve uyarılmış RAW 264,7 hücrelerinde nitrit üretimini inhibe etmiştir. Benzer şekilde, en yüksek SPL konsantrasyonuna maruz bırakıldığında RAW 264,7 hücrelerinde üretilen interlökin-6’da 9 kat azalma olmuştur. Ek olarak, BSL testinde SPL’nin lethal konsantrasyon 50’si 455,58±82,35 µg/mL iken, siklofosfamid için bu değer 16,3±0,15 µg/mL olarak belirlenmiştir. Ayrıca, hücre canlılığı SPL’den etkilenmemiştir. SPL’den on altı bileşik tanımlanırken, bunların aralarında en çok olanları timol (%29,79), 3-karen (%15,97) ve p-simenindi (%12,19). Sonuç: SPL’nin methanol ekstresi, serbest radikaller ve sitokinlerin inhibisyonu ile antioksidan ve anti-inflamatuvar aktiviteler göstermiştir. Gözlenen aktivite, bitkideki polifenolik bileşiklerle ilgili olabilir.
