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
