The phytochemical constituents of apple waste were established as potential antifungal agents against four crops pathogens, specifically, Botrytis sp., Fusarium oxysporum, Petriella setifera, and Neosartorya fischeri. Crude, purified extracts and fractions of apple pomace were tested in vitro to evaluate their antifungal and antioxidant properties. The phytochemical constituents of the tested materials were mainly represented by phloridzin and quercetin derivatives, as well as previously undescribed in apples, monoterpene-pinnatifidanoside D. Its structure was confirmed by 1D- and 2D-nuclear magnetic resonance (NMR) spectroscopic analyses. The fraction containing quercetin pentosides possessed the highest antioxidant activity, while the strongest antifungal activity was exerted by a fraction containing phloridzin. Sugar moieties differentiated the antifungal activity of quercetin glycosides. Quercetin hexosides possessed stronger antifungal activity than quercetin pentosides.

苹果废料的植物化学成分被确定为针对四种农作物病原体的潜在抗真菌剂,特别是葡萄孢菌,尖孢镰刀菌,Petriella setifera和neossartorya fischeri。在体外测试了苹果渣的粗,纯化提取物和馏分,以评估其抗真菌和抗氧化性能。被测材料的植物化学成分主要由根皮苷和槲皮素衍生物代表,以及以前在苹果中未描述的单萜-羽状花苷D。通过1D和2d核磁共振 (NMR) 光谱分析确认了其结构。含有槲皮素pentosides的馏分具有最高的抗氧化活性,而含有phloridzin的馏分具有最强的抗真菌活性。糖部分区分了槲皮素糖苷的抗真菌活性。槲皮素六苷比槲皮素五苷具有更强的抗真菌活性。
