Abstract:
Taking Gastrodia elata as test material，the effect of different harvesting period of Gastrodia elata samples aroma quality were analyzed and identified by headspace solid phase microextraction coupled with electronic nose and gas chromatography-mass spectrometry (HS-SPME-GC-MS).PCA and LDA analysis results of electronic nose technology showed that the electronic nose could distinguish different harvesting period of Gastrodia elata.According to the analysis of aroma components，65 kinds of aroma components and 19 kinds of consensus components were detected from the three harvesting period of Gastrodia elata.Among them，the relative content of alcohols and phenols in the three harvesting period of Gastrodia elata leaves was relatively high.2-ethyl-4-pentenal，2-hydroxyacetone and 2-propyne-1-alcohol were found to be unique and relatively high aroma components in harvest period Ⅰ（2017-11-07），harvest period Ⅱ（2017-12-22）,harvest period Ⅲ（2018-02-04），respectively，which indicated that different harvesting period of Gastrodia elata had their own aroma components.Therefore，different harvesting period of Gastrodia elata have different aroma due to differences in volatile components and relative contents，and electronic nose technology could effectively distinguish different harvesting period of Gastrodia elata.
