Antioxidant activity and chemical difference in fruit of differentActinidiasp.

Abstract

The present research aimed at evaluating the vitamin C, total phenolic content (TPC), phenolic compounds, carotenoids, and chlorophyll contents, as well as antioxidant activity (AAC) of six Actinidia species fruit. Vitamin C, phenolic compounds, carotenoids and chlorophylls were measured using high-performance liquid chromatography. TPC was determined using the Folin-Ciocalteau reagent, and AAC using 2,2-diphenyl-1-picryl hydrazyl (DPPH) assay. The highest concentrations of vitamin C and TPC were found for Actinidia kolomikta fruit (1008.3 and 634.1 mg/100 g fresh weight [FW], respectively). Among phenolic compounds, seven phenolic acids and three flavonoids were identified. The 2,5-dihydroxybenzoic acid prevailed in A. kolomikta (425.54 mg/100 g FW), while tannic acid dominated in other species (4.63-100.43 mg/100 g FW). The largest amounts of chlorophylls and carotenoids were identified as Actinidia macrosperma (4.02 and 2.09 mg/100 g FW, respectively). The AAC of fruit extracts decreased in the order of A. kolomikta > Actinidia purpurea > Actinidia melanandra > A. macrosperma > Actinidia arguta > Actinidia deliciosa according to the DPPH assay.

Distribution, Ploidy Levels, and Fruit Characteristics of Three <i>Actinidia</i> Species Native to Hokkaido, Japan

“…One sample of A. arguta, AA-HSP-TD, had extremely high SSC (average of 30.8%). This value was much higher than that found by others: 14%-15% in an unknown cultivar (Huang et al, 2004), 10.5% in 'Mitsu-ko' (Okamoto and Goto, 2005), 11.1%-12.8% in wild collections from Japan (Kataoka et al, 2010), 16.6% in 'Ananasnaya' and 16.8% in 'Weiki' (Latocha et al, 2010), and 10.2%-17.0% in two cultivars and 14 local collections from Japan (Kim et al, 2012); kiwifruit 'Hayward' was 13.2%-14.6% (Tavarini et al, 2008). Our data probably represent one of the highest SSC levels reported to date in A. arguta and in the genus Actinidia.…”

“…Wide variation in AAC has also been observed among cultivars, with the following values reported on a mg/100 g FW basis: 'Lande', 700; 'Pavlovskaja', 600; and 'VIR-1', 850 (Chesoniene et al, 2004); 'Dr Szymanowski', 1008 (Latocha et al, 2010); and an unknown cultivar, 211 (Zuo et al, 2012). We found much larger variability in AAC in A. arguta, with a more than eight-fold difference between the lowest and highest values.…”

Effects of solvents and extraction methods on the content and antiradical activity of polyphenols from fruits Actinidia arguta, Crataegus monogyna, Gaultheria procumbens and Schisandra chinensis

“…According to Latocha et al (2010), the content of total phenols in A. arguta was 79 mg/100 g FW. Wang (2013) reported that the content of TP in the fruits of A. arguta was 214.8 mg/100 g, whereas Zuo et al (2012) claimed that value to be higher.…”
