矿质营养元素对广藿香主要活性成分含量的影响

Effects of Mineral Nutrient Elements on the Main Active Components of Patchouli

摘要: Mg、Mn和Co3种矿质营养元素均能促进广藿香中挥发油和百秋李醇的积累，且最佳作用浓度相同，分别为：低浓度Mn (1 μM)、高浓度Mg (10 mM)和Co (1 mM)，Mn以处理1次，Mg和Co以处理2次时分别获得最高含量的挥发油，百秋李醇则均在处理1次时达到最高相对含量；α-愈创木烯和葎草烯均在高浓度Mg (10 mM)处理3次后达到相对含量最高值分别为10.39%和1.01%，中浓度Mn (10 μM)处理2次后石竹烯和法呢醇的相对含量达到最大值分别为4.49%和18.65%，刺蕊草烯和α-布藜烯分别高和低浓度Mg (10 mM和1 mM)处理1次时获得最高相对含量，刺蕊草烯为5.05%和2.95%，α-布藜烯为7.86%和5.67%。β-榄香烯和β-广藿香烯的相对含量则分别在中浓度Mn (10 μM)处理3次和高浓度Co处理2次时达到最大值，β-榄香烯为2.60%和2.83%，β-广藿香烯为0.71%和0.60%。

Abstract: The content of patchouli oil were significantly higher with applying once low concentrations of Mn (1 μM), twice high concentration of Mg (10 mM) and twice Co of medium to high concentrations (0.5 mM and 1 mM); once application of the same concentration can significantly promote the ac-cumulation of patchouli alcohol. α-Guaiene and humulene contents reached the highest value, 10.39% and 1.01%, respectively, with three times application of high concentration of Mg (10 mM). Caryophyllene and farnesyl contents were obviously increased to 4.49% and 18.65%, respectively, by applying twice of medium concentration of Mn (10 μM). Seychellene and α-bulnesene contents reached maximum levels (5.05% and 2.95%, 7.86% and 5.67%, respectively) by applying once of high (10 mM) and low (1 mM) concentrations of Mg. The highest content of β-patchoulene and β-elemene reached (2.60% and 2.86%, 0.71% and 0.60%, respectively) by three times application of medium concentration of Mn (10 μM) and twice application of high concentration of Co (1 mM).
