PISCICIDAL STEROL ACYLGLUCOSIDES FROM EDGEWORTHIA CHRYSANTA

Article abstract of DOI:10.1016/S0031-9422(00)98226-8

New potent piscicidal sterol acylglucosides named chrysanthosides have been obtained from the flower of Edgeworthia chrysantha, together with the previously known bis-coumarin and grasshopper ketone and their structures characterized to be sitosterol-3-O-6-linoleoyl- and sitosterol-3-O-6-linolenoyl-β-D-glucopyranosides by spectral data and synthesis.The natural and synthetic chrysanthosides possess potent piscicidal activity against killie-fish which was killed within 3 hr at a concentration of 0.1 ppm.
