Kaempferide triglycoside: a possible factor of resistance of carnation (Dianthus caryophyllus) to Fusarium oxysporum f. sp. dianthi

Flavonoids from carnation (Dianthus caryophyllus) and their antifungal activity

“…This finding is in agreement with those reported by Picman, Schneider, & Pieman (1995) on the antifungal activity of flavonoid compounds against the fungus Verticillium alba-atrum. Thus, the obtained data confirm that carnation is able to synthesize compounds with antifungal activity against one of its major pests, Fusarium oxysporum (Curir et al, 2001;Curir et al, 2003;Curir, Dolci, & Galeotti, 2005;Hammerschmidt, 1999;Niemann and Baayen, 1988). Flavonoids are abundant in D. caryophyllus and widespread in many other plants.…”

“…Previous study on D. caryophyllus, cultivar Novada, led to the isolation of a kaempferide triglycoside (Curir et al, 2001) that showed the ability to resist Fod infection. Now, from the active extract of cultivar Tirana we have isolated the new flavonoid tetraglycoside, kaempferol 3-O-b-D-glucopyranosyl (1 !…”

Effect of flavonoids on the development ofFusarium oxysporumf. sp.lycopersici

“…In germination assays certain flavonoids, tested within a concentration between 0.2 mM and 100 mM, have been shown to stimulate the spore germination of Fusarium solani pathogenic on legumes (Ruan et al 1995). Curir et al (2001) found a kaempferide triglycoside, involved in resistance of carnation to Fusarium oxysporum f. sp. dianthi .…”

Further flavonol and iridoid glycosides from Ajuga remota aerial parts

“…Acid hydrolysis of the compound gave rhamnose, glucose and myricetin confirmed by co-chromatography with authentic samples. [16]. The localisation of the primary glucoses on the aglycone was aided by HMBC correlations between H-1 00 (d 5.40) with C-3 (d 133.5) and between glucosyl H-1 0000 (d 5.26) with C-3 0 (d 147.2), indicating that the rhamnosylglucose biosides were at C-3 and C-3 0 of the aglycone [15].…”
