Thymyl esters derivatives and a new natural product modhephanone from Pulicaria mauritanica Coss . (Asteraceae) root oil

Abstract : Root essential oil of Pulicaria mauritanica Coss. (Asteraceae) collected from western Algeria was analysed using a combination of chromatographic (CC, GC/FID, GC(RI)] and spectroscopic [GC–MS, 13C-NMR] techniques. Thirty-eight compounds accounting for 90.4% of the whole composition were identified. The oil composition was dominated by thymyl derivatives (2,5-dimethoxy-p-cymene (37.2%), 6-methoxythymyl isobutyrate (14.2%), 10-isobutyryloxy-8,9-dehydrothymyl isobutyrate (4.8%) and thymyl isobutyrate (3.1%)), as well as by neryl isobutyrate (11.1%). A new natural compound was isolated and the structure was elucidated as 1S,2S,5S,8S-modhephan-3-one (relative stereochemistry)
