SESQUITERPENE GLYCOSIDES AND PHENYLPROPANOID ESTERS FROM PHONUS-ARBORESCENS (CARTHAMUS-ARBORESCENS)

The tert-butylmethyl ether extract of the aerial parts of Phonus arbor escens (L.) G. Lopez (Carthamus arborescens L.) afforded three new ses quiterpene glycosides, 10-epi-gamma-eudesmol beta-D-fucopyranoside (1) , 10-epi-gamma-eudesmol 2'-O-acetyl-beta-D-fucopyranoside (2), and 4,5 -dioxo-10-epi-4,5-seco-gamma-eudesmol 2'-O-acetyl-beta-D-fucopyranosid e (3), together with two new phenylpropanoid esters, 3-(3,4-dihydroxyp henyl)propyl myristate (4) and 3-(3,4-dihydroxyphenyl)propyl palmitate (5) in addition to a series of known compounds. The structures of the new compounds were established by spectroscopic and chemical methods.
