e main purpose of this work was to assessthe antioxidant activitiesofthen-hexane, ethyl acetate and methanol extracts of Strobilanthes schomburgkiileaves collected in Laocai province, Vietnam. Total phenolic and flavonoid contents were determined. The DPPH, H2O2 radical scavenging activity, and total antioxidant activityviaphosphomolybdenum method were investigated. The results showedthat the methanol extractconcludeda high concentrationof phenolicsand flavonoidswhich were 65.42 mg/gand 52.05 mg/g, respectively. There was a significant correlation between total phenolic and flavonoid concentrationsand EC50values of different antioxidantassays.The antioxidant properties of the different extracts from Strobilanthes schomburgkiileaveswere reported for the first time

Species of Miliusa are of interest to many scientists worldwide. Several studies have been conducted on some species of this genus. However, information on the research of Miliusa species in Vietnam remains very limited. There is almost no systematic and comprehensive research on these entities in Vietnam with the aim of establishing their long-term utilization. Within the scope of this research topic, the research group obtained 05 Miliusa specimens in Thua Thien Hue province. Plant specimens were dried, ground, and assigned scientific names by Dr. Nguyen The Kyong of the Institute of Ecology and Biological Resources, Vietnamese Academy of Science and Technology. The specimens were dried, ground, protocols were prepared, sealed in vacuum bags, and stored in the Biotechnology Laboratory of the Faculty of Chemistry and Environment, Hue University.
