Abstract:

To study the constituents of volatiles from Melaleuca bracteate leaves, we analyzed and identified the volatile constituents in M. bracteate leaves with headspace solid-phase micro extraction (HS-SPME) and gas chromatography-mass spectrometry (GC-MS) techniques. In addition, the results were compared with the essential oil in M. bracteate leaves extracted by steam distillation (HD). The results showed that 76 kinds of volatile compounds were detected, accounted for 97.28% of the total peak area, while 37 kinds of volatile compounds were detected from the essential oil extracted by HD, accounted for 99.67% of the total peak area. The volatile compounds extracted from M. bracteate leaves by HS-SPME, mainly contained ether, alkene, esters, alcohols, phenol, and aldehydes. The relative content of ether was the largest and the methyleugenol was the maximum constituent, up to 72.42%. Methyleugenol was also the main compound of essential oil from M. bracteate leaves extracted by HD, reached 91.48%. Therefore, M. bracteate shows the great potential in plant protection because of the high content of methyleugenol.

Key words: Melaleuca bracteata leaves, volatile compound, headspace solid-phase micro extraction (HS-SPME), gas chromatography-mass spectrometry (GC-MS)
