Flavonoids from the leaf resin of snakeweed gutierrezia sarothrae


, : Flavonoids from the leaf resin of snakeweed gutierrezia sarothrae. Zeitschrift fuer Naturforschung Section C Journal of Biosciences 42(1-2): 73-76

The resinous material excreted by aerial parts of snakeweed, Gutierrezia sarothrae, was analyzed for flavonoid aglycones. Six major flavonoids were characterized by their spectral data; nine minor flavonoids were identified by direct comparisons with markers. The major flavones form three pairs of isomeric products, five of which are 6,8-methoxylated.

T84 cells, a human intestinal epithelial cell line, serve as a model of electrogenic Cl- secretion. We find that cAMP-elicited Cl- secretion in T84 cells is accompanied by a marked redistribution of F-actin in the basolateral portion of the cell....
