英文摘要	the combination of the lipidome and the metabolome can provide much more information in plant metabolomics studies. a method for the simultaneous extraction of the lipidome and the metabolome of fresh tobacco leaves was developed. method validation was performed on the basis of the optimal ratio of methanol to methyl tert-butyl ether to water (37:45:68) from the design of experiments. good repeatability was obtained. we found that 92.2 % and 91.6 % of the peaks for the lipidome and the metabolome were within a relative standard deviation of 20 %, accounting for 94.6 % and 94.6 % of the total abundance, respectively. the intraday and interday precisions were also satisfactory. a total of 230 metabolites, including 129 lipids, were identified. significant differences were found in lipidomic and metabolomic profiles of fresh tobacco leaves in different geographical regions. highly unsaturated galactolipids, phosphatidylethanolamines, predominant phosphatidylcholines, most of the polyphenols, amino acids, and polyamines had a higher content in yunnan province, and low-unsaturation-degree galactolipids, triacylglycerols, glucosylceramides with trihydroxy long-chain bases, acylated sterol glucosides, and some organic acids were more abundant in henan province. correlation analysis between differential metabolites and climatic factors indicated the vital importance of temperature. the fatty acid unsaturation degree of galactolipids could be influenced by temperature. accumulation of polyphenols and decreases in the ratios of stigmasterols to sitosterols and glucosylstigmasterols to glucosylsitosterols were also correlated with lower temperature in yunnan province. furthermore, lipids were more sensitive to climatic variations than other metabolites.
