tailieunhanh - Chemical constituents of some essential oils bearing plants growing wild in Vietnam

Litsea baviensis Lecomte, which belongs to the family Lauraceae. The plant was found in China, Thailand and Vietnam (Ban, 2003; Wu et al., 2008). In Vietnam, this species has been recorded in Lao Cai, Son La, Ha Noi, Ninh Binh, Thanh Hoa, Nghe An, Khanh Hoa provinces (Vietnamese as Bời lời Ba Vì). Notably, in the present study, this plant also was added distribution area in Vietnam (Dak Nong province). | ACADEMIA JOURNAL OF BIOLOGY 2023 45 4 83 92 DOI 2615-9023 18944 CHEMICAL CONSTITUENTS OF SOME ESSENTIAL OILS BEARING PLANTS GROWING WILD IN VIETNAM Nguyen Phuong Hanh1 Nguyen Thi Hien1 Nguyen Quoc Binh2 Dinh Thi Thu Thuy3 1 Institute of Ecology and Biological Resources Vietnam Academy of Science and Technology 18 Hoang Quoc Viet Ha Noi Vietnam 2 Vietnam National Museum of Nature Vietnam Academy of Science and Technology 18 Hoang Quoc Viet Ha Noi Vietnam 3 Institute of Natural Product Chemistry Vietnam Academy of Science and Technology 18 Hoang Quoc Viet Ha Noi Vietnam Received 18 September 2023 accepted 25 December 2023 ABSTRACT The essential oils of three plants were isolated by hydrodistillation and their constituents were analyzed by gas chromatography-mass spectrometry flame ionization detection GC MS-FID method. 29 compounds representing of the total oil of inflorescences of Zingiber pellitum were identified consisting mainly of α-pinene β-caryophyllene and α-humulene . For Basilicum polystachyon 41 and 37 components were identified in the leaf and flower oils accounting for and of the total oils respectively. Germacrene D and germacrene B and α-cubebene and 19 04 α-copaene and δ-cadinene and β-cis-elemene and and γ-elemene and were the major constituents in both oils. For the leaves of Litsea bavienes 40 components were identified representing of the total oil contents in which hepten-3-one was the most abundant compound in this oil. The chemical constituents of essential oils from Z. pellitum inflorescences B. polystachyon leaves and flowers and L. baviensis leaves were being reported for the first time.
