Two new flavanone glucosides, (2S)-5, 7, 3', 5'-tetrahydroxy-flavanone 7-O-β-D-allopyranoside (1) and (2S)-5, 7, 3', 5'-tetrahydroxy-flavanone 7-O-β-D-glucopyranosie (2) were isolated from the stems and leaves of Jasminum lanceolarium, along with five known compounds : Betulinaldehyde (3), betulinic acid (4), betulin (5), syringin (6) and Liriodendrin (7). Their structures were determined on the basis of spectroscopic and chemical methods. The isolated compounds were screened for their in vitro antioxidant activity through DPPH (1, 1-diphenyl-2-picrylhydrazyl) radical scavenging assay. Compounds 2 demonstrated significant radical scavenging activity.
