Volatiles in the Lysimachia clethroides Duby by head space solid phase microextraction coupled with gas chromatography-mass spectrometry (HS- SPME-GC-MS)

Abstract

We studied for the first time, the volatile compounds in the Lysimachia clethroide Duby by using head space solid phase microextraction (HS-SPME) coupled with gas chromatography-mass spectrometry (GC-MS). The results showed that 14 compounds were identified from the stem of L. clethroides, 13 compounds were identified from the leaves, and 16 compounds from the flowers. 8 compounds were mutual components, accounting for 92.99, 94.59 and 90.32% of the identified components in stem, leaves and flowers, respectively. Limonene was the main compound in the three parts, and the contents were up to 52.59, 54.57 and 44.98%, respectively. These showed that the volatiles had not much difference in the three parts; maybe the three parts have the same medicinal effect, and could provide certain theoretical basis for further development and utilization. Key words: Lysimachia clethroides Duby, solid phase microextraction, volatiles.
