Variation of Phenolics and Antioxidant Activity between Peel and Pulp Parts of Pear (pyrus Communis L.) Fruit
The aim of present study was to appraise the antioxidant activity and phenolic contents in peel and pulp parts from two locally harvested verities of pear. The extraction yield of antioxidant components obtained with 80% methanol (80:20 methanol-water v/v) was found to be 14.30-17.50% for peel and 11.50-13.00 g/100 g for pulp on dry weight basis. The total phenolic contents and total flavoniod ...
متن کاملIdentification of QTLs controlling harvest time and fruit skin color in Japanese pear (Pyrus pyrifolia Nakai)
Using an F1 population from a cross between Japanese pear (Pyrus pyrifolia Nakai) cultivars 'Akiakari' and 'Taihaku', we performed quantitative trait locus (QTL) analysis of seven fruit traits (harvest time, fruit skin color, flesh firmness, fruit weight, acid content, total soluble solids content, and preharvest fruit drop). The constructed simple sequence repeat-based genetic linkage map of '...
متن کاملGenetic Relationships among Pyrus pyrifolia Cultivars from Southeastern China and Japan
A total of 90 Pyrus pyrifolia cultivars from southeastern China and Japan were used to assess genetic diversity and overall similarity using eight Amplified Fragment Length Polymorphism (AFLP) primer combinations. Eighty-eight percent of the 429 bands produced were polymorphic. Unweighted Pair Group Method with Arithmetic Mean (UPGMA) cluster analysis of these data support two major groups, mos...
متن کاملVariability in antioxidant activity and phenolic profile in different parts of sunflower (Helianthus annuus L.) genotypes
Sunflower (Helianthus annuus L.) is largely consumed in Iran as an oleaginous and confectionery product. In this study, the total phenolic and flavonoid contents, antioxidant activity and phenolic composition in different parts of the seeds from six sunflower genotypes were investigated. The antioxidant activity of extract was evaluated by different assays. The total phenolic and flavonoid cont...
