Description
Summary:This is the first report concerning the natural products of the hitherto unstudied (L.) Gren. & Godr., a member of the tribe Cichorieae (Asteraceae). From aerial parts and roots of this plant, five sesquiterpene lactones and one coumarin were isolated. The compounds were identified as sonchuside A, 11β,13-dihydrolactucin-8- -acetate, 11β,13-dihydrolactucin, cichorioside B, 11β,13-dihydrolactucin-8- -acetate-15- -β-glucopyranoside and coumarin - cichoriin. Their structures were established by H NMR. Moreover, HPLC/PAD analysis of a hydroalcoholic extract from the aerial parts of the plant revealed the presence of caffeic acid derivatives, coumarins and flavonoids commonly found in lettuces.[Formula: see text].
