The highest oleoresin harvested from Sample A occurred at October 2003 to May 2004 (in the later dry season to early rainy season); the highest oleoresin harvested from Sample B occurred at September and October 2003 (in the later dry season), and from Sample C in June (in the later rainy season). The percentage of the major volatiles of the oleoresin of Samples A and C (Sample A: β-caryophyllene, trans-α-bergamotene, β-selinene and β-bisabolene; Sample C: β-caryophyllene and β-bisabolene) changes in a minor extent during the seasons. However, appreciable changes were observed from the percentage of β-caryophyllene and β-bisabolene in the Sample B. In the same way, appreciable changes were observed on the amount of oleoresin harvested: Sample A: 10 mL to 500 mL, Sample B: zero to 3000 mL, Sample C: zero to 70 mL. In conclusion, for the all samples of C. duckei studied here, we observed considerably changes in the amount of oleoresin harvested. Nevertheless, the percentage of the main components of Samples A and C were not affected in a great extent. Contrary, the Sample B, the percentage of the major compounds changes considerably during seasons.

Seasonal variation of oleoresin and volatiles from copaifera martii hayne growing wild in the state of pará, Brazil / Maria das Graças B. Zoghbi in The journal of essential oil research, Vol. 19 N°6 (Novembre/Decembre 2007)

Zoghbi, Auteur ; Osmar A. Lameira, Auteur ; Elaine C. P. Oliveira, Auteur Année de publication : 2008 Article en page(s) : pp. 504-506 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Copaifera  martii  Fabaceae  α-copaene  δ-cadinene  Oleoresin Résumé : The oleoresins from Copaifera martii were harvested from September 2003 at one-month intervals up to September 2004, from the same individual tree, and examined by GC/FID and GC/MS. The highest oleoresin per harvest occurred at January 2004 in the dry Amazonian season. The major volatiles of the oleoresin, α-copaene and δ-cadinene, changes from 36.4% to 51.2% and 13.7% to 17.3%, respectively. No appreciable changes were observed on the percentage of the volatile compounds during the seasonal observation, but the percentage of essential oils in the oleoresins also changes considerably (1.3% −21.3%). The amount of oleoresin harvested ranged from 0–100mL. In conclusion, for the specimen of C. martii studied, during the seasonal observation, oleoresin per harvested and the percentage of the essential oil changes considerably during seasonal observation, but the chemical composition were not affected. According our knowledge this is the first reported of the volatiles and seasonal observation from C. martii.
