Abstract

Within the framework of the research program on species of the family Magnoliaceae Juss. containing essential oils in Vietnam, we have conducted a field survey using routine investigation method and assessed the biodiversity of some Magnoliaceae species in some areas of Son La province. A total of nine species of Magnoliaceae family were sampled in districts of Moc Chau and Van Ho, and one species distributed in Yen Chau district was referenced from previous document. Out of the total of 10 species, 3 species (Magnolia clemensiorum, Magnolia fistulosa, and Michelia sonlaensis) are endemic to Vietnam, 4 species have been assessed as endangered at different levels in Vietnam (Magnolia balansae and Magnolia dandyi) and at the global level (Magnolia chevalieri and Michelia sonlaensis) requiring a conservation plan to maintain biodiversity. All 10 studied species of the Magnoliaceae family have valuable timber, some species are grown as ornamental plants due to their fragrant and beautiful flowers, and some species are used as medicines to treat a number of diseases in traditional medicine. By hydrodistillation, all 9 species collected in Moc Chau and Van Ho districts were determined to contain essential oils in their branches, leaves, and fruits.
