摘 要: 为确定宣木瓜适宜采收期提供依据。定期采集同一基地宣木瓜样品,以芦丁为标准品,采用分光光度法测定不同时期的总黄酮含量。结果表明:果实生长过程中的总黄酮含量在0.94%~1.62%之间,以7月8日含量最高;宣木瓜适宜采收期为每年的7月上旬至中旬。 To provide the basis for determining the appropriate harvest time of Chaenomeles speciosa, samples were picked regularly in the same base, and total flavone content of samples was tested by speetrophotometry using rutin as the standard sample. The results showed that the flavone content was 0.94 %-1.62 % during the fruit growth process, and the highest content was on July 8; The best harvest period of Chaenomeles speciosa should be early to mid-July each year.
