Piscidic acid and fukiic acid esters from Cimicifuga simplex1Part 24 in the series “Constituents of Cimicifuga spp.”, and Part 2 in the series “Phenolics of Cimicifuga spp.” For part 23 see Ref.[1].1

Abstract

Investigation of the underground parts of Cimicifuga simplex afforded five new piscidic acid esters and two new fukiic acid esters: 2-caffeoyl piscidic acid, 2-feruloyl piscidic acid, 2-isoferuloyl piscidic acid, 2-feruloyl piscidic acid-1-methyl ester, 2-isoferuloyl piscidic acid-1-methyl ester, 2-feruloyl fukiic acid-1-methyl ester, and 2-isoferuloyl fukiic acid-1-methyl ester.
