Abstract
Three new acylphloroglucinol glucosides, rhodosides A-C (1-3), and three known ones (4-6) were isolated from the roots of Lysidice rhodostegia. The new structures were identified by MS, NMR, and acid hydrolysis. In addition, the antioxidant capacities of the isolated compounds were evaluated using DPPH radical-scavenging assay, and compounds 1-6 exhibited obvious antioxidant activities with IC50 values of 24.65 ± 1.27 to 38.11 ± 1.35 μM.
Keywords:
Acylphloroglucinol glucoside; Antioxidant activity; Lysidice rhodostegia.
