Table 1 Terpenic compounds (average ± RSD %) identified by SPME-GC × GC-MS technique in the headspace samples of Dracaena spp. resin. The compounds were identified by a comparison of their MS fragmentation patterns and retention indices (RI) with synthetic standards and values published previously. In the absence of standards, identifications were carried out by a comparison with the reference spectra NIST library, the Wiley/NBS registry of mass spectral data, and published retention indices.

tr ≤ 0.3%. Key: DD - Dracaena draco subsp. draco from Canary Islands, DDA - D. draco subsp. ajgal from Marocco, DO - D. ombet from Ethiopia, DC - D. cinnabari from Socotra, DS - D. serrulata from Oman. a The numbering of the compounds corresponds with Fig. 1. b Abbreviation corresponding to Fig. 2, M1-8 monoterpenes, S1-12 sesquiterpenes. c Typical mass spectrometric fragments confirmed with those published by Adams (2007), and by Joulain and König (1998) for monoterpenes and sesquiterpenes identification, respectively. d Retention indices (RI) on DB-5 column. e Retention time (RT) in seconds on 1st, and 2nd column, respectively. RI ref Reference retention indices as published by f Babushok et al. (2011), g Joulain and König (1998), and h Adams (2007).
