摘要:

探明温度对贯叶连翘挥发性有机化合物(volatile organic compounds,VOCs)合成积累的影响,更加有效地调控活性组分的生物合成。以不同温度(15、22、30℃)处理的贯叶连翘组培苗为材料,对地上部分无水乙醇提取液进行气相色谱-质谱(gas chromatography- mass spectrometry,GC-MS)分离鉴定。3个温度共分离鉴定81个挥发性组分,其中15、22、30℃下分别鉴定出37、39、43种化合物;总峰面积比较后发现,随着温度升高总挥发性组分相对含量显著降低,22、30℃相对15℃分别降低约7%和21%;各挥发性组分相对含量比较后发现,23个化合物的相对含量随温度升高而逐渐降低或仅存于15℃。温度对贯叶连翘中VOCs的种类和积累量具有显著影响,相对低温有利于总VOCs的合成积累。

Abstract:

The paper aims to unveil the effect of temperatures on biosynthesis and accumulation of VOCs and effectively regulate the biosynthesis of bio-actives constituents in Hypericum perforatum. The ethanol extracts from aerial parts of H. perforatum seedlings at 15, 22 and 30℃ treatments were respectively separated and identified by GS-MS. Total 81 volatiles were identified at the three temperatures, and 37, 39 and 43 compounds were identified at 15, 22 and 30℃, respectively. Comparison of the total peak area showed that the relative content (RC) of total volatiles significantly decreased with the temperatures increase, with a 7% and 21% decrease at 22 and 30℃ compared with that at 15℃, respectively. Comparison of the individual RC found that 23 compounds presented a decrease with the temperatures increase or only existed at 15℃. The constituents and accumulation of VOCs in H. perforatum are significantly affected by temperature, and relative low temperature can enhance the biosynthesis and accumulation of VOCs.

Key words: Hypericum perforatum, temperature, GC-MS, volatile organic compounds, biosynthesis regulation
