摘要：

One new alkylresorcinol derivative, cichoriol B, and a mixture of three other ones, cichoriols A, C, and D, were isolated from the dichloromethane extract of Cichorium spinosum, a plant that is used traditionally in the Cretan diet. The methanol extract afforded one new sesquiterpene lactone, (4R)-3,4-dihydrolactucopicrin. The structures of the new compounds were determined by spectroscopic methods, mainly by the concerted application of 1 D and 2D NMR techniques (HMQC, HMBC, NOESY).
