초록
Hymenoxys brachyactis지상부의 디클로로메탄 추출액으로부터 3개의 sesquiterpene lactone들과 새로운 lactone화합물인 isohymenograndin을 확인하였다. 그리고 2개의 sesquiterpene lactone축합물인 biennine C와 독성이 있는 것으로 알려진 flavone화합물인 hispidulin을 분리하여 각각을 고자장 NMR, Mass등의 기기를 이용하여 구조결정 하였다. Biennine C는 gas chromatography와 Mass분석을 통하여 독성화합물 hymenoxon과 화합물 8과의 Diels-Alder축합물임을 확인하였다. biennine C를 포함한 이상의 lactone화합물들은
The dichloromethane extracts of the above ground parts of Hymenoxys brachyactis afforded three sesquiterpene lactones already reported, one new sesquiterpene lactone, biennin C and hispidulin as known toxic flavone. Structures of all compounds were established by spectroscopy and biennin C was determined as an adduct of the modified pseudoguanolide and hymenoxon by Gas Chromatograpy and MS spectrometer These sesquiterpene lactones have the same
