Seven new oleanane-type triterpenoids (1-7), named fatsicarpains A-G, and the known compounds 3α-hydroxyolean-11,13(18)-dien-28-oic acid (8) and 3α-hydroxyolean-11-en-28,13β-olide (9) were isolated from the leaves and twigs of Fatsia polycarpa on the basis of bioassay-guided fractionation. The

Nine new derivatives of oleanane triterpenoids isolated from Fatsia polycarpa Hayata were synthesized through chemical transformations. Acetylation was effected by reaction with acetic anhydride in pyridine to afford compounds 1-5, while compound 6 was obtained using

Due to their potent antimicrobial activity, silver nanoparticles (AgNPs) synthesized by biomass might be promising in food preservation, whereas effects of AgNPs on Penicillium italicum-induced rot of Citrus fruits have not been investigated. In this study, a novel AgNPs biosynthesis method was
