摘要
通过对覆盆子成熟过程中颜色进行数字化表征,并对其水浸出物、醇浸出物、总黄酮、总多糖、总多酚、鞣花酸、椴树苷、山柰酚-3-O-芸香糖苷多种物质成分进行含量测定,采用相关回归对颜色与成分之间的相关性进行分析。结果表明L^(*)与总多酚、山柰酚-3-O-芸香糖苷及椴树苷有显著的正相关性,与总黄酮及鞣花酸、水浸出物含量有中度正相关性。a^(*)与总多酚、山柰酚-3-O-芸香糖苷及椴树苷呈显著负相关,与总黄酮、水浸出物、鞣花酸呈中度相关性。b^(*)与水浸出物呈显著负相关,与总多酚、总多糖、醇浸出物、山柰酚-3-O-芸香糖苷含量呈中度相关性。说明覆盆子成熟过程中颜色与物质成分动态变化有较显著相关性,根据其颜色与品质指标的动态变化规律确定的较适宜采收期在4月下旬至5月1日前后,果实未变黄之时采收最佳,此时相关农艺性状为果实直径为(12.49±0.56) mm,高为(14.25±1.19) mm,果实质量为(1.20±0.14) g,其色度值L^(*)为52.87±3.14,a^(*)为-2.01±1.58,b^(*)为28.31±3.88。该研究结果为建立覆盆子外观颜色从经验转向客观量化的评价模式奠定基础。
The color of Rubus chingii was characterized by digital method, and the content of water extract, alcohol extract, total flavonoids, total polysaccharides, total polyphenols, ellagic acid, linden glycoside, kaophenol-3-O-rutin were determined. Correlation regression was used to analyze the correlation between color and composition. The results showed that L^(*) was positively correlated with total polyphenols, kaophenol-3-O-rutin and tilide, and moderately positively correlated with total flavones, ellagic acid and aqueous extracts. The a^(*) value was negatively correlated with total polyphenols, kaophenol-3-O-rutin, and linden glycosides, while was moderately correlated with total flavones, aqueous extracts, and ellagic acid. The b^(*) value was negatively correlated with the water extract, and moderately correlated with the content of total polyphenols, total polysaccharides, alcohol extract and kaophenol-3-O-rutin, which showed that R. chingii mature color had a significant correlation with material composition in the process of dynamic change. According to the law of dynamic change in the color and quality indexes, it is determined that the appropriate harvest time is in late April to May 1, while the fruit is not turn yellow. The agronomic traits related to fruit was(12.49±0.56) mm in diameter,(14.25±1.19)mm in height,(1.20±0.14) g in weight, the chroma L^(*) value was 52.87±3.14,a^(*) value was 2.01±1.58, b^(*) values was 28.31±3.88. The results lay a foundation for establishing an objective quantitative evaluation model of R. chingii color from experience.
