Phloroglucinol derivatives from Aeromonas hydrophila.
greenhouse-grown red pine seedling, Pinus resinosa, when cultured on malt agar or potato dextrose agar (PDA) showed inhibitory activity against selected test fungi. Sensitive fungi included Ceratocystis ulmi (BUISM.) C. MOREAU, Pythium spp., Rhizoctonia solani KUHN, Cylindrocarpon sp., Fusarium oxysporum SCHLECT., and Sirococcus strobilinus PREUSS. When grown on PDA, a colorless crystalline sol...
متن کاملAntioxidant activity of two phloroglucinol derivatives from Dryopteris crassirhizoma.
The rhizome of Dryopteris crassirhizoma NAKAI exhibited significant antioxidant activity, as assessed by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity in vitro. Two phloroglucinol derivatives, flavaspidic acids PB (1) and AB (2), were isolated from the rhizome of D. crassirhizoma by a bioassay-guided fractionation. 1H-, 13C-NMR, and UV analysis were used to determine the ...

متن کاملLocalization of Prenylated Flavonoids in Sophora flavescens var. angustifolia Plants
A histochemical analysis was carried out on the distribution of flavonoid derivatives in Sophora flavescens var. angustifolia plant. Prenylated flavonoids such as kushenol I, kurarinone, sophoraflavanone G and des-O-methylanhydroicaritin were mainly localized in the peri derm (cork layers, and cork layer-like tissues scattered in parenchymatous tissues of the root system). Pterocarpan derivati...
متن کاملDistribution of foliar formylated phloroglucinol derivatives amongst Eucalyptus species.
Formylated phloroglucinol compounds (FPCs) in Eucalyptus leaves are important determinants of feeding in marsupial folivores and have a wide range of other biological actions. We conducted a survey of the occurrence of formylated phloroglucinol compounds (euglobals, macrocarpals and sideroxylonals) in acetone-petrol extracts of 41 species of Eucalyptus from among seven informal subgenera growin...
