黑果腺肋花楸果实内含物变化规律研究
Study on the Changes of Contents in Aronia melanocarpa Fruit

为掌握辽西地区黑果腺肋花楸果实成熟后其花青素、花色苷、黄酮、总酚、可溶性固形物及Vc含量的变化规律，从2020年9月1日开始至10月21日，每隔10 d采集黑果腺肋花楸果实，采用分光光度法等分析化验方法分析上述活性物质不同时期含量，基于SPSS进行方差分析，结果表明：黄酮、花青素、花色苷、总酚这几类物质在黑果腺肋花楸果实未完全成熟时含量较低，随着果实成熟度的增加，上述几类物质呈现增加趋势，并在10月上旬达到高峰，随后逐渐下降；在果实未完全成熟及初始成熟的黑果腺肋花楸Vc含量最高；果实未完全成熟时可溶性固形物含量最低，果实成熟后其含量基本维持在一个相对稳定的水平；在辽西地区，黑果腺肋花楸适宜的采收期应该是9月11日至10月11日之间，这一阶段采收，其内含物含量大多处于丰富水平。
In order to learn the optimal harvest time of Aronia melanocarpa in western Liaoning Province, the variation patterns of anthocyanin, flavonoid, total phenol ,soluble solid and Vc contents in fruit at different ripening stages of Aronia melanocarpa were researched in this paper. The fruit was collected in every 10 days from September 1 to October 21, 2020 and tested for above active substances at different stages by spectrophotometry and other analytical methods. The ANOVA analysis results based on SPSS software, the results showed that flavonoid, anthocyanin and total phenol contents were low in fruit not completely ripe and gradually increased with the increase of fruit maturity, reaching peak in early October, and then decreasing gradually. The content of Vc was the highest in immature and initial ripening fruit and the content of soluble solids was the lowest in immature fruit, basically maintaining at a relatively stable level after fruit ripening. Therefore, the optimal harvest time of Aronia melanocarpa in Western Liaoning Province was between September 11 and October 11, and the content of inclusions was rich at this stage.
