“…It has been reported that procyanidin B2 has a significant impact on blue mould development with partial resistance to this disease in various commercial apple cultivars (Ahmadi-Afzadi et al 2015). However, our results do not support this finding.…”

“…Some studies have shown higher concentrations of patulin in organic apple products compared to conventional ones (Tournas andMemon 2009, Piqué et al 2013). In contrast, it has been proposed that in organic production apples are able to create a natural barrier against the attack of pathogens by increased synthesis of phenolic compounds (Wojdyło et al 2010) and that higher levels of phenolic compounds reduces fungal growth in fruits (Ahmadi-Afzadi et al 2015).…”

The aims of this study were to find out if organic apple juice (AJ) contained higher contents of polyphenols or patulin compared to conventional AJ, and if higher storage temperature before processing increases patulin content in juice. AJ was pressed from Estonian, Danish and Norwegian apples. Additionally, three cultivars from Estonian organic and conventional orchards were stored at 3±2 °C and 9±2 °C before processing. Patulin, polyphenol content and antioxidant capacity were determined in pasteurized juices. In 2015, 33% of conventional (n=6) and 46% of organic (n=11) juices contained patulin; two of the organic juices above the legal limit (191 and 64µg l-1). In 2016, none of the AJs contained patulin. Patulin occurrence was more affected by weather conditions two weeks before harvest than by cultivation system and apple storage temperature. Polyphenol content was higher in organic than in conventional juices and was reduced at higher apple storage temperature.

“…The peel extract contents of total phenolic and flavonoids were higher than the flesh extract of C. tuberosus. The results were in agreement with the research conducted by Ahmadi-Alfazi et al (2015) and Saidani et al (2017). Total phenolics compounds acres fills up in higher amounts extracted with a more polar solvent.…”

Three different solvents were used to extract the phytochemical compounds in the peel and flesh of Coleus tuberosus. The results of extraction with different solvents were compared based on the levels of phytochemicals compounds and its antioxidant activity. Extraction of bioactive compounds was done by the maceration method using methanol, ethyl acetate, and chloroform for seven days at a ratio of 1:5 (w/v). Determination of total phenolic contents and flavonoids was conducted via spectrophotometric method. Antioxidant activity was evaluated based on DPPH, peroxide value and TBA value. The results showed that the methanol solvent extracted higher total phenolic and flavonoids compounds than the ethyl acetate and chloroform. The antioxidant activity of methanol extracts was higher compared to ethyl acetate and chloroform extracts for both flesh and peel of C. tuberosus. The extract of the peel of C. tuberosus had antioxidant activity higher compared to the flesh extract with the use of methanol, ethyl acetate or chloroform as solvent. There was a positive and significant correlation between total phenolic and flavonoids content against DPPH and a negative and significant correlation with peroxide and TBA value.

“…The role of polymethoxylated flavones in disease resistance has also been revealed in the metabolomic analysis of a spontaneous yellow citrus mutant that is more resistant to green mold infection (Luo et al, 2015). In a recent study involving 24 apple varieties, correlation analysis revealed that phenols like flavonols and procyanidins B2 in the peel fraction of the inoculated fruit have a significant impact on blue mold resistance (Ahmadi-Afzadi et al, 2015). The comparison of tomato fruits that accumulate different levels of flavonoids and show different ripening behavior has also shed light on the role that specific flavonoids with high superoxide scavenging activities play in the higher resistance of some tomato lines to B. cinerea infection (Zhang et al, 2015).…”

Fruit losses during postharvest storage and handling due to pathogen infections are one of the major problems in the global food chain supply. The application of chemical fungicides to control diseases is currently limited by legislation in some countries and also raises concerns about food and environmental safety. Exploring molecular aspects of pathogen-fruit interactions therefore has biological and economic significance as a means to help develop rational alternatives for disease control. In this review we present the current knowledge of molecular aspects in pathogen-fruit interactions, addressing the following topics: the application of new "omics" technologies for studying these interactions; the molecular mechanisms of fungal pathogen attack; the regulation of virulence by exogenous factors; and, finally, fruit defense mechanisms.
