摘  要：
为解析沙米和藜麦两种植物的种子代谢物,利用GC×GC-TOF MS平台开展非靶向沙米和藜麦种子代谢组分析。科尔沁沙地沙米、腾格里沙漠沙米和山西静乐藜麦种子检测到了106个代谢物。沙米代谢物相对含量有6个显著高于、17个显著低于藜麦,其余代谢物没有显著差异。在沙米代谢组中相对含量较高,而在稻米和小麦代谢组中都没有检测到的代谢物有棉籽糖、原儿茶酸和木糖醇等,这些代谢物可弥补稻米和小麦的营养不足。对以稻米或小麦为主食的人群来说,沙米是理想的药食同源食物。

摘  要：
To understand seed metabolites of Agriophyllum squarrosum and Chenopodium quinoa,untargeted metabolomics analysis of sand rice and quinoa seeds had been conducted using GC × GC-TOF MS platform. A total of 106 metabolites were identified in sand rice seeds harvested from Horqin sandy land and Tengger Desert and Quinoa seeds produced in Jingle,Shanxi,China. The metabolites had similar relative contents between sand rice and quinoa except of six metabolites higher and 17 metabolites lower in sand rice than in quinoa. Some metabolites such as raffinose,dihydroxybenzoic acid,and xylitol had a high content in sand rice but could not be identified in rice and wheat. These metabolites may complement the lack of nutrients in rice and wheat. Sand rice is a perfect affinal drug and diet for people who eat mainly rice or wheat.
