TL;DR: The data suggest that plants in the Lemnaceae O-substitute flavones but do not C-glycosylate them, and evidence was obtained that flavones containing a 4′-monohydroxy B-ring can be oxidized to flavones with a 3′,4′-dihydroxy A-ring.

TL;DR: The distribution of these compounds is consistent with the genetic relationships between the species and a new C-glycosyl flavone, O-xylosylisovitexin, was detected in T. dubius.

TL;DR: In this paper, the isolation and structure determination of tetraneurin-A, a new pseudoguaianolide from Parthenium alpinum var. tetranuris, are described.

TL;DR: A new flavonol triglycoside which was isolated from the fern Ophioglossum vulgatum L. is shown to be 3-O -methylquercetin 7-O-diglucoside 4′- O -glucosides.

TL;DR: In this paper, a new germacranolide dilactone from Ambrosia psilostachya was synthesized, which was shown to have a 10:7 ratio of two conformers.

TL;DR: New collections of Ambrosia artemisiifolia were found to contain the pseudoguaianolides cumanin, peruvin and dihydrocumanin - the first report of the natural occurrence of dihydromin.

TL;DR: Isorhamnetin-3-O -rutinoside has been shown to be the only flavonoid in Batis maritima as mentioned in this paper, which is the same as the one used in this paper.
