PATULITRIN AND ACETYL PATULITRIN, FLAVONOL GLYCOSIDES FROM LAGASCEA-MOLLIS

The genus Lagascea, family Compositae, is native to Mexico and contains eight species. Little previous phytochemical work has been reported. The polyene ketone, dehydrofalcarinone, was isolated from the roots of L. mollis Cav. (1); and an unknown alkaloid, resin, and a fluorescent material were obtained from L. spinosis sima Cav. (2). We were able to obtain samples of plant material from T. F. Stuessy, of the Botany Department, who has reexamined the classification of this genus (3). © 1979, American Chemical Society.
