Eicosenones and methylated flavonols from Amomum koenigii

Two novel eicosenones, 1-methoxy-E-4-eicosen-3-one and 1-(4'-hydroxyphenoxy)-E-4-eicosen-3- one, together with eleven known methylated flavonols were isolated from the fruits of Amomum koenigii. Their structures were elucidated by spectroscopic techniques.
