C-glycosyl flavones from Peperomia blanda
(ELSEVIER SCIENCE BV, 2009)
The methanol extract from aerial parts of the Peperomia blanda (Piperaceae) yielded two C-glycosyl-flavones. Their structures were elucidated on the basis of extensive spectroscopic analysis, including 1D and 2D NMR, ...
Apigenin produced by maize flavone synthase I and II protects plants against UV-B-induced damage
(Wiley Blackwell Publishing, Inc, 2019-02)
Flavones, one of the largest groups of flavonoids, have beneficial effects on human health and are considered of high nutritional value. Previously, we demonstrated that maize type I flavone synthase (ZmFNSI) is one of the ...
Identification and characterization of maize Salmon silks genes involved in insecticidal maysin biosynthesis
(American Society of Plant Biologist, 2016-06)
The century-old maize (Zea mays) salmon silks mutation has been linked to the absence of maysin. Maysin is a C-glycosyl flavone that, when present in silks, confers natural resistance to the maize earworm (Helicoverpa zea), ...
Anti-Candida and anti-Cryptococcus evaluation of 15 non-alkaloidal compounds from Pterogyne nitens
(2016-10-01)
Objective To evaluate anti-Candida and anti-Cryptococcus activities of 15 non-alkaloidal compounds from Pterogyne nitens Tulasne (Leguminosae), a South American medicinal plant. Methods Compounds were submitted to antifungal ...
Profiling the Cymbopogon nardus Ethanol Extract and Its Antifungal Potential against Candida Species with Different Patterns of Resistance
(2020-09-01)
The essential oil of Cymbopogon nardus, citronella, has been extensively studied. However, the chemical and biological properties of the ethanolic extract (EE) of C. nardus have not been evaluated. The aim of this study ...
Binding of antioxidant flavone isovitexin to human serum albumin investigated by experimental and computational assays
(Elsevier B.V., 2014-09-01)
The flavonoids are a large class of polyphenolic compounds which occur naturally in plants where they are widely distributed. Isovitexin (ISO) is a glycosylated flavonoid that exhibits a potential antioxidant activity. ...
Identification of a Bifunctional Maize C- and O-Glucosyltransferase
(American Society For Biochemistry And Molecular Biology, 2013-10)
Flavonoids accumulate in plant vacuoles usually as O-glycosylated derivatives, but several species can also synthesize flavonoid C-glycosides. Recently, we demonstrated that a flavanone 2-hydroxylase (ZmF2H1, CYP93G5) ...
