In a patent, introducing its new discovery.
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-beta-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. Keywords: Edgeworthia chrysantha; Thymaaelaeaceae; flower; sitosterol-3-O-6-linoleoyl- and sitosterol-3-O-6-linolenoyl-beta-D-glucopyranoside; grashopper ketone; daphnoretin; piscicidal activity; synthesis of chrysanthoside
