Analysis of composition of CH2Cl2 surface extract of leaves of Amphoricarpos neumayeri Vis. revealed 16 sesquiterpene lactones with guaianolide skeleton, so called amphoricarpolides, typical for this genus. Four of them, 13-16, were new derivatives and their structures were elucidated by detailed analyses of IR, NMR and MS data. Amphoricarpolide (9), its 15-O-acetyl derivative (5), and two 9 beta-hydroxyamphoricarpolides, 3,15-di-O-acetyl- and 3-O-acetyl-15-O-isovaleroyl derivatives (3 and 6, respectively) were tested for in vitro protective effect on chromosome aberrations in peripheral human lymphocytes using cytochalasin-B blocked micronucleus (CBMN) assay. The tested compound exerted a beneficial effect by decreasing DNA damage of human lymphocytes.
