Quantification of the flavonoids in yellow lupin (Lupinus luteus; Leguminosae) seedlings revealed that a flavone glucoside, 7-O-beta-(2-O-beta-rhamnosyl)glucosyl-4',5,7-trihydroxyflavone (apigenine 7-O-beta-neohesperidoside), is rich in the epicotyl and cotyledon. In hypocotyls and roots, 8-C-beta-glucosyl-4',5,7-trihydroxyisoflavone (genistein 8-C-beta-glucoside) was a predominant flavonoid co...
The existence of di-glucosylated derivative of T-2 toxin in plant (corn powder) was confirmed for the first time in addition to that of HT-2 toxin. These masked mycotoxins (mycotoxin glucosides) were identified as T-2 toxin-di-glucoside (T2GlcGlc) and HT-2 toxin-di-glucoside (HT2GlcGlc) based on accurate mass measurements of characteristic ions and fragmentation patterns using high-resolution l...
The chromatographic fractionation of the Mauritia flexuosa L. f., Arecaceae, leaves extract, a plant known by the name of buriti palm tree, resulted in the isolation of six flavonoids: tricin-7-O-rutinoside, apigenin-6-C-arabinoside, 8-Cglucoside (isoschaftoside), kaempferol-3-O-rutinoside (nicotiflorine), quercetin-3O-rutinoside (rutin), luteolin-8-C-glucoside (orientin) and luteolin-6-C-gluco...
Z. Naturforsch. 50c, 345-352 (1995); received January 27/February 20, 1995 Liverworts, Frullania, Flavone Aglycones, Acylated Flavone Glycosides, Chemotaxonomy From Frullania teneriffae 5 known flavone aglycones and 6 flavone glycosides were iso lated, among them the new 6-OH-luteolin-6-0-ß-D-glucoside-7-0-ß-D-glueoside-6'"-(3-hydroxy-3-methylglutaroylester). F. cesatiana contains 2 flavone-di...
Chemical analysis of the aqueous and n-butanol fractions methanolic extract Stipagrostis plumosa Munro ex T.Anderson, Poaceae, aerial parts led to isolation seven known phenolic glycosides 3,4′-dihydroxypropiophenone-3-O-β-d-glucoside, 5′-methoxy-3,4′-dihydroxypropiophenone-3-O-β-d-glucoside, 3′5′-dimethoxy-3,4′-dihydroxypropiophenone-3-O-β-d-glucoside, 3,4,5-trimethoxyphenyl-β-d-glucopyranose,...
Centaurea is one of the most important genera within family Asteraceae. An investigation phytochemical composition bruguieriana using Gas-Chromatography coupled to Mass spectrometry (GC-MS) was performed. Antimicrobial activity evaluated minimum inhibitory concentration method (MIC) and validated by molecular docking for major compounds active fraction (1,10-di-epi-cubenol methyl 8-oxooctanoate...
Astragalus is a well-known genus in Leguminosae family that represented more than 800 species growing in Iran. Nevertheless, there are a few reports on Astragalus plants endemic to Iran. The roots of Astragalus plants are rich in saponins, flavonoids and polysaccharides that possess various pharmacological activities. In present study, Chemical components, antioxidant and antibacterial activity...

Reversed-Phase High-Performance Liquid Chromatography with Electrochemical Detection of Anthocyanins
Anthocyanins, flavonoid compounds present in grapes and wines, were determined by reverse-phase high-performance liquid chromatography (RP-HPLC) with electrochemical detection (RP-HPLC-ED). The method developed consists of RP-HPLC gradient elution with voltammetric detection using a glassy carbon electrode after separation in an Inertsil ODS-3V analytical column. Good peak resolution was obtain...
