To analyze the aroma components and their contents of jasmine planted in different regions of Guangxi Hengxian County, and the content of trace elements in the corresponding soil activity, so as to provide a reference for the improvement of jasmine planting technology and the improvement of scented tea scenting technology. [Method] Collect commercial jasmine patterns and soil samples of corresponding plots from 11 typical jasmine planting sites in Hengxian County, Guangxi (spots 1-11), and perform GC-MS detection on the volatile components of jasmine. Detect the content of trace elements in soil activity, analyze the difference in aroma component content of jasmine planted in different regions and the correlation between the content of main aroma components and the content of trace elements in soil activity, and explore the effect of trace element content in different activities on the main aroma through regression analysis The effect of component accumulation. [Results] The aroma components of jasmine in Hengxian County, Guangxi contained 7 types of compounds including alcohols, esters, aldehydes, ketones, acids, alkanes and others. 242 identifiable volatile substances were detected in 22 jasmine samples from 11 jasmine planting sites. Among them, the higher content substances are (E)-2-hexenal, linalool, benzaldehyde, and hexyl aldehyde. The average relative content of aldehyde and (E)-3-hexen-1-ol are 21.72, 12.06, 5.21, 2.75 and 2.37, respectively; the total aroma components of jasmine in samples 3, 4, 9, 10 and 11 The relative content is higher than the average. The results of correlation analysis and regression analysis showed that the content of exchangeable calcium and exchangeable magnesium in the soil and the relative content of jasmine aroma components ranked the top 10 (E)-2-hexenal, hexanal, and octamethylcyclotetrasiloxane The content of alkane and 2-octanone was significantly (P<0.05, the same below) or extremely significantly (P<0.01) negatively correlated, and positively correlated with the content of caproic acid. [Conclusion] The aroma components and content of jasmine in different planting areas in Hengxian County of Guangxi are quite different, but the location of the sampling point has no obvious correlation with the aroma components of jasmine. The aroma components of jasmine are mainly divided into alcohols, esters, aldehydes, ketones, acids and alkane compounds, etc.; during the formation and accumulation of the aroma components of jasmine, the content of exchangeable calcium and exchangeable magnesium in the soil increases. It can inhibit the accumulation of (E)-2-hexenal, hexanal, octamethylcyclotetrasiloxane and 2-octanone in jasmine, and promote the increase of hexanoic acid content, therefore, adjust the soil exchangeable calcium and exchangeable magnesium content It can be used as an important method to optimize the subsequent jasmine planting technology.
