【摘要】 探讨金柑果实发育过程中总酚含量、总黄酮含量及总酚酸含量的动态变化差异。以尤溪金柑品种金弹为试验材料,对不同生长发育期金柑果实中总酚含量、总黄酮含量及总酚酸含量进行检测分析。结果表明:随着成熟度的增加,花后55～65d金柑果实中总黄酮含量和总酚酸含量随着成熟度的增加而急剧减少,花后85d左右变化平缓,到接近成熟的花后125d左右,黄酮含量和酚酸含量小幅上升后下降;果皮中的黄酮含量和酚酸含量大于果肉。金柑果实含有丰富的酚类物质,随着果实的生长发育呈现逐渐降低的趋势;金柑果实总酚与类黄酮含量呈显著正相关;金柑幼果比成熟果具有更高的酚类物质和更强的抗氧化能力。更多还原

【Abstract】 The dynamic changes of total phenol content,total flavonoid content and total phenolic acid content in Fortunella crassifolia during the fruit development were studied.The contents of total phenols,total flavonoids and total phenolic acids in Fortunella crassifoliafruit at different growth stages were determined and analyzed by using the variety of kumquat in Youxi as the experimental material.The results showed that:the contents of total flavonoids and total phenolic acids in the fruit of kumquat decreased sharply with the increase of maturity at 55-65 days after flowering,and changed gently at around 85 days after flowering,and then at about 125 days after flowering,the flavonoid content and phenolic acid content increased slightly and then decreased after 125 days after flowering;The flavonoid content and phenolic acid content in the pericarp was higher than that in the flesh.The fruit of kumquat was rich in phenolic substance and it tended to decrease with the growth and development of the fruit.The content of total phenols and flavonoids in the fruit of kumquat was positively correlated.The young fruit of kumquat had higher phenolic substance and stronger antioxidant ability than the ripe fruit.更多还原
