An extract from the entire Ixriss denticulata f. pinnatipartita plant afforded the guaianolide sesquiterpene lactone glucoside, 8β,15-dihydroxy-1(10),3,11(13)-guaiatrien-12,6-olide-15-O-glucopyranoside, along with the known flavonoids luteolin-7-O-glucoside and luteolin-7-O-glucuronide-6'-methyl ester; their structures were determined by spectroscopic methods. Ixerin Y inhibited the growth of human breast cancer MCF7 and MDA468 cell lines.
