	1	Antioxidant and antimicrobial properties of Litsea elliptica Blume and Litsea resinosa Blume(Lauraceae)显示文摘Objective:To investigate antioxidant and antimicrobial activities of two plant species,Litsea elliptica(L elliptica) and Litsea resinosa(L resinosa).Methods:In vitro method-2,2-diphenyl-1-picrylhydrazyl radical scavenging assay was conducted for antioxidant activity detennination while antimicrobial assay consisted of agar well diffusion assay and mycelial radial growth assay.Results:Methanol extracts of root and stem of L elliptica and L resinosa exhibited the highest antioxidant activity with EC_(50)of 23.99,41.69,11.22 and 33.48 mg/l.respectively.All methanol extracts of L resinosa as well as root extracts from L elliptica showed significant scavenging activity.Hexane extract from stem of L resinosa presented the largest inhibition zone in Gramnegative bacteria Pseudomonas aeruginosa and Escherichia coli while chloroform extract from inner bark of L resinosa showed major inhibition towards Gram-positive bacteria Bacillus subtilis.Essential oils from the root of both species showed significant antifungal activities which are 80.11%and 66.85%respectively.Conclusions:Overall,methanol extracts from root and stem of both species showed antioxidant activity comparable to standard butylated hydroxytoluene.Extracts from L resinosa demonstrated stronger antimicrobial properties compared to that from L elliptica.
