Chemical composition of the needle and cone essential oils of pinus fenzeliana (pinaceae) from Vietnam

The needle and cone essential oils of Pinus fenzeliana Hand-Mazz. (Pinus kwangtungensis Chun & Tsiang) collected in Hang Kia-Pa Co Nature Reserve, Hoa Binh province were obtained by hydrodistillation and analyzed by a combination of GC-FID, GC-MS and NMR (Gas Chromatography/Gas Chromatography-Mass Spectrometry/Nuclear Magnetic Resonance (NMR) analysis). | ACADEMIA JOURNAL OF BIOLOGY 2023 45 4 127 135 DOI 10.15625 2615-9023 19053 CHEMICAL COMPOSITION OF THE NEEDLE AND CONE ESSENTIAL OILS OF Pinus fenzeliana Pinaceae FROM VIETNAM Tran Huy Thai1 Nguyen Thi Hien1 Trinh Xuan Thanh1 Nguyen Quang Hung1 Mathieu Paoli2 Ange Bighelli2 Joseph Casanova2 1 Institute of Ecology and Biological Resources Vietnam Academy of Science and Technology 18 Hoang Quoc Viet Ha Noi Vietnam 2 University de Corse CNRS UMR 6134 SPE Equipe Chimie et Biomasse Ajaccio France Received 2 October 2023 accepted 21 December 2023 ABSTRACT The needle and cone essential oils of Pinus fenzeliana Hand-Mazz. Pinus kwangtungensis Chun amp Tsiang collected in Hang Kia-Pa Co Nature Reserve Hoa Binh province were obtained by hydrodistillation and analyzed by a combination of GC-FID GC-MS and NMR Gas Chromatography Gas Chromatography-Mass Spectrometry Nuclear Magnetic Resonance NMR analysis . The oil yields were 0.2 and 0.37 respectively v w on dry weight basis . Twenty-seven compounds were detected in both needle and cone oils accounting for 98.0 and 98.2 of the whole composition respectively. The main components identified in the needle oil were α-pinene 20.7 β-pinene 11.3 -3-carene 32.2 limonene 8.0 and E-β-caryophyllene 7.1 . The cone oil contained mainly α-pinene 19.3 β-pinene 45.4 -3-carene 3.5 limonene 12.7 and E-β-caryophyllene 3.4 . This is the first report on the chemical composition of the cone essential oil of P. fenzeliana from Vietnam. Keywords Pinus fenzeliana α-pinene β-pinene -3-carene limonene and E-β-caryophyllene.
