뽀리뱅이 전초로부터 분리한 Sesquiterpene 배당체
2010
【Extensive phytochemical investigation of the methanol extract from the whole plant of Youngia japonica (Asteraceae) led us to the isolation of a new guaiane-type sesquiterpene (1), together with three related guaianolides, youngiajaponicoside A (2), crepiside H (3) and crepeside E (4). The chemical structure of 1 was elucidated by the aid of spectroscopic analyses including 2D-NMR experiments (COSY, HMBC, HMQC and ROESY). The isolated components (1-4) were evaluated for the inhibitory effect on the proliferation of four cultured human tumor cell lines such as A549, SK-OV-3, SK-MEL-2 and HCT-15, in vitro.】
