| Popis: | This study aimed to evaluate the influence of collection zone on total phenol, flavonoid and glucosinolate contents and antioxidant and anti-inflammatory activities of caper ( Capparis sicula ssp. sicula). This species has been characterized through the detection, isolation and quantitative evaluation of chemical markers (polyphenols, flavonoids and glucosinolates). The chemical investigation showed a different composition between the two collection zones. While the total amounts of phenolics and flavonoids of the two samples were quite the same, their high-performance liquid chromatography profiles were very different. In both samples, the most abundant aglycone was quercetin which accounted for 60% of total flavonoids. Nuclear magnetic resonance data analysis allowed the identification of two compounds: 3,5-dicaffeoylquinic and 4,5-dicaffeoylquinic acids which represented 6.67% and 15.94%, respectively, of the total amount of flavonoids in sample 1. In sample 2, these two acids were still present, but their percentages were much less (2.20% and 1.71%, respectively). As far as we know, this is the first report about the presence of dicaffeoylquinic acids in Capparis. With regard to glucosinolate content, sample 1 showed a higher content of glucosinolates. In both samples, glucocapparin was the most abundant compound. Antioxidant activity of the methanolic C. sicula extracts using diphenyl picrylhydrazyl, β-carotene bleaching test and oxygen radical absorbance capacity showed that the sample 2 was more active than 1. As regards the inhibition of NO production, the extracts from sample 2 were more active than those from sample 1. |
