The results are given of the identification of (-)-trans-khellactone and its 4'-methyl ether and (-)-3'(S),4'(S)-trans-3'-senecioyloxy-4'-angeloyloxy-3',4'-dihydroseselin and of the establishment of the structure of three new khellactone derivatives - campestrol (VII), C19H22O6, <α>D20+32 deg (c 7.8; chloroform), campestrinol (X), C24H26O7, mp 116-118 deg C, and campestrinoside (I), C20H24O10, mp 172-173 deg C, <α>D -272.5 deg (c 4.7; ethanol).It has been shown on the basis of chemical and spectral characteristics that campesol, earlier described as a new substance, is a mixture of two isomeric compounds - 4'-hydroxy-3'-senecioyloxy-3',4'-dihydroseselin and 3'-angeloyloxy-4'-hydroxy-3',4'-dihydroseselin.
