Magnolia citrata Noot. & Chalermglin was collected in the Central Highlands of Vietnam and examined for its essential oils’ chemical compositions and antimicrobial activities. The essential oils were obtained from the leaves, twigs, and stem barks of M. citrata using hydrodistillation, then analyzed using Gas Chromatography-Mass Spectrometry (GC-MS) and evaluated for antimicrobial activities. | ACADEMIA JOURNAL OF BIOLOGY 2023 45 3 13 22 DOI 2615-9023 18231 CHEMICAL COMPOSITION AND POTENTIAL FOR ANTIMICROBIAL PROPERTIES OF Magnolia citrata NOOT. amp CHALERMGLIN MAGNOLIACEAE ESSENTIAL OILS IN CENTRAL HIGHLANDS OF VIETNAM Nguyen Hai Dang1 Luu Dam Ngoc Anh2 3 Tu Bao Ngan2 Nguyen Anh Huyen4 Bui Van Huong2 3 Patrick Arpino5 1 University of Science and Technology of Hanoi 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 Graduate University of Science and Technology Vietnam Academy of Science and Technology 18 Hoang Quoc Viet Ha Noi Vietnam 4 Institute of Microbiology and Biotechnology Vietnam National University 144 Xuan Thuy Ha Noi Vietnam 5 Chimie Paris Tech 75231 Paris Cedex 05 France Received 6 April 2023 accepted 19 September 2023 ABSTRACT Magnolia citrata Noot. amp Chalermglin was collected in the Central Highlands of Vietnam and examined for its essential oils chemical compositions and antimicrobial activities. The essential oils were obtained from the leaves twigs and stem barks of M. citrata using hydrodistillation then analyzed using Gas Chromatography-Mass Spectrometry GC-MS and evaluated for antimicrobial activities. The yields of essential oils were and from twigs leaves and stem barks respectively. A total of forty-three compounds were identified in essential oils accounting for and respectively. The major constituents of the oils from leaves and twigs varied slightly. Accordingly geranial neral linalool and sylvestrene were found in the leaves while geranial neral sylvestrene and linalool were found in the twigs. In addition sylvestrene was the major component comprising of the stem bark oils. Other compounds present in high quantities in this oil included safrole geranial sabinene and neral . The .
