为全面揭示和利用我国枸杞属植物资源,这项研究确定并比较了单糖的含量,多糖,蛋白质,类胡萝卜素,有机酸,8种不同枸杞的干果中含有酚类物质。此外,包括百果重量在内的特征,形状指数,并测量了种子与果实的比例,并评估了化学成分含量与果实性状之间的相关性。结果表明,L.barbarumvar。auranticarpum,和L.dasystemumvar。金霉属是单糖含量高的物种。L.barbarum和L.barbarumvar。金木是总多糖含量高的物种,L.barbarum是类胡萝卜素含量高的物种。云南和中国。potaninii具有高含量的可溶性蛋白质。L.truncum,L.dasystemum,和L.barbarum显示高含量的有机酸和酚。L.barbarum和L.barbarumvar。auranticarpum显示出高果实重量,而L.yunnanense和L.chinense的种子与果实的比例很高。多变量统计分析表明,多糖,类胡萝卜素,百果重,种子与果实的比例,东pol碱,果糖,5-O-阿魏酸,山奈酚-3-O-鲁丁苷,scopoletin,隐绿原酸,咖啡酸是不同品种枸杞果实中的主要差异化合物。此外,相关分析结果表明,果实性状与化合物含量之间存在很强的相关性。具体来说,百果重与总多糖和石膏矿含量呈正相关。籽果比与芦丁含量呈负相关,山奈酚-3-O-鲁丁苷,果糖,和葡萄糖,与琥珀酸的含量呈正相关,可溶性蛋白质,和玉米黄质.结果表明,化合物在8种枸杞果实中呈现不同的分布规律。本研究为综合开发利用提供了依据,有针对性的育种,和枸杞植物的增值应用。
To comprehensively reveal and utilize the plant resources of Lycium in China, this study determined and compared the content of monosaccharides, polysaccharides, proteins, carotenoids, organic acids, and phenols in the dried fruits of 8 different Lycium species. Furthermore, the
traits including the hundred-fruit weight, shape index, and the ratio of seed to fruit were measured, and the correlations between the content of chemical compounds and fruit
traits were assessed. The results showed that L. truncatum, L. barbarum var. auranticarpum, and L. dasystemum var. rubricaulium were the species with high content of monosaccharides. L. barbarum and L. barbarum var. auranticarpum were the species with high content of total polysaccharides, and L. barbarum was the species with high content of carotenoids. L. yunnanense and L. chinense var. potaninii had high content of soluble proteins. L. truncatum, L. dasystemum, and L. barbarum showed high content of organic acids and phenols. L. barbarum and L. barbarum var. auranticarpum demonstrated high fruit weight, while L. yunnanense and L. chinense had high ratios of seed to fruit. The multivariate statistical analysis indicated that polysaccharides, carotenoids, hundred-fruit weight, ratio of seed to fruit, scopolamine, fructose, 5-O-feruloylquinic acid, kaempferol-3-O-rutinoside, scopoletin, cryptochlorogenic acid, and caffeic acid were the main differential compounds in the fruits among different species of Lycium. Moreover, the results of correlation ananysis showed strong correlations between fruit
traits and compound content. Specifically, the hundred-fruit weight had positive correlations with the content of total polysaccharides and scopola-mine. The ratio of seed to fruit was negatively correlated with the content of rutin, kaempferol-3-O-rutinoside, fructose, and glucose and positively correlated with the content of succinic acid, soluble proteins, and zeaxanthin. The results implied that chemical compounds presented different distribution patterns in the fruits of 8 Lycium species. This study provides a basis for the comprehensive development and utilization, targeted breeding, and value-added application of Lycium plants.
