Abstract

This study aimed to evaluate the compositional diversity of essential oilproducing species within the Asteraceae family at Muong La Nature Reserve, Son Laprovince. A comprehensive identification revealed a total of 56 species distributedacross 39 genera. In addition to the value for essential oils, species of theAsteraceae family also demonstrate multiple application aspects, includingmedicinal (Th) with 54 species; and food (Tp) with 19 species. Additionally, 7species as ornamental plants (Ca) while others are used for ornamental, andenological purposes. Fifteen Asteraceae species have a use value (UV) index ≥ 0.80,and 1 species (accounting for 1.72%) is identified as potentially threatened, listedin the Red Data Book of Vietnam 2007. Life forms of Asteraceae species studiedare constructed as follows: the Spectrum of Biology (SB) = 50.00 % Ph + 21.43 %Th +16.07% Hm + 12.50% Ch. In the study area, the Asteraceae family iscategorized into 6 main geographical factors: tropical Asia accounts (accountingfor 78.57% of the total number), followed by Crop factor with 5 species(accounting for 8,93% of the total number) and Northern temperate elements with3 species (accounting for 5.36%); Paleo-tropical with 2 species (accounting for3.57%); The lowest factors include; Tropical Asia-Australia-America and subendemic with the same 1 specie (accounting for 1.79%).
