摘　　要：采用液相色谱-质谱联用的代谢组学技术分析了安徽亳州和浙江嘉兴两地所产番红花(Crocus sativus)的主要代谢活性物质种类和数量的差异,结果表明,不同产地番红花中主要活性物质的种类大体相同,但其数量差异显著。安徽亳州产番红花较浙江嘉兴产番红花能够积累更多的番红花醛、番红花酸和番红花甙,说明不同的生长环境对番红花的内在品质产生了很大的影响。进一步比较发现传统的加热烘干处理方法明显损失番红花醛、番红花酸和番红花甙等活性物质,但同时增加了部分风味氨基酸的含量。本研究为选择番红花栽培环境和改良其加工技术提供基础数据。Metabolomics analysis using liquid chromatography-mass spectrometry(LC-MS) was employed to detect a wide spectrum of active substances in saffron(Crocus sativus) harvested from Bozhou, Anhui and Jiaxing, Zhejiang. The quantity difference between the main active substances in saffron from these two areas was also identified. Our results show that although the chemical compositions were similar, the quantities of active substances varied greatly. Saffron produced from Bozhou contained higher quantities of safranal, crocetin and picrocrocin than that from Jiaxing, which strongly indicates that the growing environment has a great influence on the inner quality of saffron. Furthermore, traditional processing methods of heating and drying clearly reduced the amounts of safranal, crocetin and picrocrocin, but enhanced the content of some flavor amino acids. This study provides basic information for determining optimal cultivation conditions and improving processing techniques by saffron growers.
