摘要: 为研究红枣感染黑斑病后营养成分的变化情况,针对南疆7 个不同地区枣园中采集的14 个健康红枣和黑斑病红枣样品,分析其中31 种营养指标(糖类、氨基酸、总酸、总糖、还原糖、蛋白质和矿物质元素)及4 种主要有毒代谢产物(链格孢毒素)的含量变化。结果发现:相比于健康红枣,黑斑病枣中检测的7 种矿物质元素下降显著;所检测的17 种氨基酸中,有8 种苦味氨基酸(Val、Iie、Leu、Tyr、Phe、His、Lys、Arg)均升高,1 种甜味氨基酸(Pro)显著降低;果糖、蔗糖、还原糖、总糖、总酸、水溶性蛋白质含量明显降低,葡萄糖含量升高;毒性最强的细交链孢菌酮酸(tenuazonic acid,TeA)在所有样品中均检出,其在健康枣中检出含量显著低于黑斑病枣。另外,通过偏最小二乘-判别分析发现链格孢酚、天冬氨酸、蛋氨酸、TeA和赖氨酸这5 项指标可作为判别健康红枣和病枣的主要判别因子,为后续开展红枣感染黑斑病后的代谢组学研究提供思路。

Abstract: In order to study the changes of the nutrients in red jujubes after being infected with black spot disease, we analyzed 14 infected and healthy jujube samples collected from 7 jujube orchards in South Xinjiang for 31 nutritional components (sugars, amino acids, total acid, total sugar, reducing sugars, proteins and mineral elements) and four main toxic metabolites (Alternaria toxins). Results showed that the contents of 7 mineral elements were decreased significantly in infected jujubes as compared with healthy ones. Among the 17 amino acids detected, the contents of 8 bitter amino acids (Val, Iie, Leu, Tyr, Phe, His, Lys, and Arg) were all increased while one sweet amino acid, Pro, was significantly decreased. The contents of fructose, sucrose, reducing sugar, total sugar, total acid and water-soluble protein were significantly reduced, whereas glucose content was increased. Tenuazonic acid (TeA), the most toxic among the four metabolites, was detected in all samples, at a significantly lower level in health jujubes than in infected ones. In addition, by partial least squares discriminant analysis we found that alternariol (AOH), aspartic acid, methionine, TeA and lysine could act as main indicators to distinguish between healthy and infected jujubes. This research provides novel ideas for future metabolomics research of red jujubes infected with black spot disease.
