【摘要】 研究万寿菊花提取物α-三连噻吩对葡萄的保鲜效果,以万寿菊花为原料,用氯仿提取其中光活化杀虫物质α-三连噻吩,研究了α-三连噻吩对葡萄的保鲜试验中各项指标的变化。试验表明含有α-三连噻吩的保鲜剂可明显降低葡萄贮藏期间的失重率和呼吸强度,并且可延缓葡萄中V_C和有机酸含量的下降,使葡萄果实在贮藏期间保持较高的好果率和超氧化物歧化酶(SOD)活性。含有α-三连噻吩的保鲜剂的保鲜效果好于传统的单一壳聚糖成分的保鲜剂。更多还原

【Abstract】 In oder to research the application of α-terthienyl from marigold in fresh-keeping of grape, the marigold flower was used to extract photoactivited pesticide α-terthienyl with chloroform. Index of grape in storage with α-terthienyl from marigold was researched. The fresh-keeping experiments showed that the α-terthienyl extract can reduce the weight loss rate and respiration intensity of grape in storage, which can also delay the decreasing of V_C and organic acids in grape, keep excellent fresh fruit rate and physiological activity of superoxide dismutase( SOD) in grape, so the fresh-keeping effect of α-terthienyl extract is better than classical single chitsan composition preservative.更多还原
