关键词： Ficus carica L   biochemical assessment   morpho-agronomic   screening   germplasm  

摘要： This study aimed to screen 135 cultivars of fig (Ficus carica L.) to identify the most suitable cultivars in terms of morpho-agronomic and biochemical characters. The free radical scavenging activity was assessed through DPPH, ABTS and beta-Carotene bleaching assays. The studied genotypes exhibited significant variability (p < .01) following all traits analyzed. The Canonical Correlation Analysis (CCA) revealed a significant relationship between biochemical components and morpho-agronomic traits of fig. With the exception of the drop at the ostiole, lenticel color, and seed sizes, all variables showed highly significant differences. All studied genotypes averaged the fruit weigh of 34.41 +/- 14.78 g with a dominance of globose shape. Based on the principal component analysis, the most discriminant attributes were the fruit geometrical traits, color, and peel characteristics. Also, the total sugars (10.08-15.10 g/100 g(dw)), total anthocyanins (0,41 to 47.95 mg cy-3-rutinoside/100 g(dw)) and flavonoids (103,7 +/- 8.9-14.6 +/- 4.6 mg CE/100 g(dw)) contributed significantly in fig assessment. Unweighted pair group cluster analysis based on Euclidean distance revealed five distinct groups. The local genotype 'Ounq Hmam PS14MODIFIER LETTER PRIME showed a typical profile and was classified as an independent branch. The findings confirmed the effectiveness of combining morpho-agronomic and biochemical analyses in fig assessment. They also showed that the studied fig germplasm has high phenotypic diversity, which is probably more genetically related. The studied accessions can be recognized as an important gene pool for future breeding programs.

关键词： Apigenin   Bisphenol a   Hepatotoxicity   Liver   Oxidative stress   Rats  

摘要： Apigenin (APG) is a phytopolyphenol widely distributed in the human diet and has been reported to exert antioxidant effects, such as lowering oxidative stress. This study has been designed to investigate the ameliorating effect of APG against oxidative stress induced by bisphenol A(BPA) in the liver and testis of male rats. Rats were divided into five groups of five animals each: G1 (control group), G2 (BPA 1 mg/kg ***), G3 (BPA 10 mg/kg ***), G4 (BPA + APG;1 + 20 mg/kg/***) and G5 (BPA + APG;10 + 20 mg / kg/***).The treatments have been given by gavage to rats daily for 30 days. After the last day of treatment, rats were sacrificed by decapitation after exposure to ether. The results showed that BPA exhibited a decrease in the body weight of rats. In addition, BPA significantly decreased the level of testosterone, LH, and reduced glutathione (GSH) and increased the level of alanine aminotransferase, aspartate aminotransferase, bilirubin, and glutathione S-transferase (GST) compared with the control group. Moreover, the administration of APG decreased the levels of the liver biomarkers and improved the antioxidant stress state. The results suggested that APG supplementation with BPA-treated rats elicited a reduction of the toxic effects of the endocrine disruptors by improving the studied parameters, which was confirmed by the histological study of the testis structure and gonadal axis. Apigenin appears to have a promising prophylactic effect through its effective anti-radical action against the hepatotoxic and reprotoxic effects of BPA. © 2020, Springer-Verlag London Ltd., part of Springer Nature.
