Hydrodistillation Essential Oil of Michelia balansae and its Characteristics from Xuan Son National Park, Vietnam

Abstract

Background and Objectives: Michelia balansae, belonging to the genus Michelia, consists of approximately 80 species including 26 species that were discovered in Vietnam. This genus was reported as a source of essential oils, which were principally collected in one season of the year. This study aimed to discover the variety of essential oils from leaves of M. balansae grown in Xuan Son Nation Park, Vietnam, collected various winter and summer. Materials and Methods: Essential oils from M. balansae leaves obtained during winter and summer were extracted by hydrodistillation method with optimal conditions (ratio solid:liquid 1:4 and 120 min of distillation time). The chemical composition of essential oil was analyzed by using the GC/MS method. Results: The optimal conditions including solid-liquid ratio (1:4 or 1:5) and distillation time (120-150 min) for the extraction of essential oil from M. balansae leaves were determined in this study. Moreover, the components of essential oil from M. balansae leaves collected during these two periods were identified. Conclusion: The present study provides further insights into the seasonal variation of essential oil compounds of M. balansae.
