Carroll, Wilawan Mahabusarakam The leaves of Artocarpus elasticus collected in Thailand were investigated for chemical constituents. Four new prenylated dihydrochalcones named elastichalcones C, D, E, F (1, 3, 5, 6) together with elastichalcone B (2) and artocarpanone (4) were isolated. Their structures were determined from analysis of spectroscopic data. Elastichalcone C (1) exhibited good antibacterial activity and cytotoxicity. Graphical abstract
