摘要
为全面了解及利用我国枸杞属植物资源,该研究以枸杞属不同种植物干燥成熟果实为研究对象,比较其糖类、蛋白质类、类胡萝卜素类、有机酸类及酚类化学组分组成及含量,并结合果实百粒重、果形指数及籽实比性状指标,分析其“化学-性状”相关性。研究结果表明,不同种枸杞其化学成分主要组成类别具有差异,如截萼枸杞、黄果枸杞及红枝枸杞为单糖优势种;宁夏枸杞及黄果枸杞为总多糖优势种,且宁夏枸杞为枸杞红素绝对优势种;云南枸杞与北方枸杞干果为可溶性蛋白质优势种;截萼枸杞、新疆枸杞及宁夏枸杞为有机酸类及酚类优势种;宁夏枸杞、黄果枸杞为枸杞属中大果优势种;云南枸杞及枸杞为多籽劣势种。多糖类、类胡萝卜素类、果实百粒重、籽实比、东莨菪素、果糖、5-O-阿魏酰奎宁酸、山柰酚-3-O-芸香糖苷、东莨菪苷、隐绿原酸及咖啡酸被认为是不同种干果间主要差异指标。相关性分析结果表明,果实百粒重与东莨菪苷及总多糖含量呈强正相关;籽实比与琥珀酸、水溶性蛋白质及玉米黄素含量呈强正相关性,与芦丁、山柰酚-3-O-芸香糖苷、果糖及葡萄糖含量呈强负相关,表明不同化合物在枸杞果实中分布趋势不同。该研究系统分析比较了枸杞属8个不同种果实化学组分及性状差异,可为枸杞属植物全面开发利用及品种定向选育和精细化、高值化利用提供参考依据。
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.
