New diprenylated dihyrochalcones from leaves of Artocarpus elasticus

- Two new diprenylated dihydrochalcones, named elastichalcone A and elastichalcone B, were isolated from leaves of Artocarpus elasticus.
- The structures were elucidated on the basis of spectroscopic data.
- The compounds were evaluated for free radical scavenging activity.
- Elastichalcone B exhibited strong free radical scavenging activity with IC50 value of 11.30 μg/ml.
