对成熟期的早生温州蜜柑、夏橙共9个栽培品种果实中的多甲氧基黄酮类化合物和香豆素的含量及其结构特征进行了研究。 取24g新鲜果皮置于混合器中,加入40ml乙醇绞碎,向混合物中加入乙醇至100ml后过滤,滤液进行HPLC分析。再取未成熟的和小的果实进行以上试验,容积减半。 对5种温州蜜柑和4种夏橙的栽培品种进行研究,果实成熟期,其果皮的多甲氧基黄 The contents and structural characteristics of polymethoxylated flavonoids and coumarins in fruit of 9 cultivars of early-harvest Satsuma orange and summer orange in mature period were studied. 24g of fresh peel was placed in a mixer, 40ml of ethanol was added and ground, ethanol was added to 100ml of the mixture, and the filtrate was filtered. The filtrate was subjected to HPLC analysis. Then take the immature and small fruits for the above test and halve the volume. A study was conducted on five varieties of Satsuma mandarin and four varieties of summer orange. During fruit ripening, the polymethoxyl yellow of the pericarp was observed.
