Litsea glutinosa samples collected from Thai Nguyen and Thua Thien‐Hue province were investigated chemically and biologically. As results: There were remarkable differences in chemical constituents and biological activities between two Litsea glutinosa samples. Flavonoid glycosides, megastigmanes and aporphine alkaloids were isolated and identified from the sample collected in Thua Thien Hue province, while no flavonoid glycosides, only three aporphine alkaloids and some fatty acids and fatty acid esters were isolated from the sample collected in Thai Nguyen province. The ethanol extract of sample from Thua Thien‐Hue province showed a stronger α‐ glucosidase inhibition than that of the sample from Thai Nguyen province. The in vivo antidiabetic activity of Thua Thien‐Hue sample was evaluated. The result was promising.
