Accessible Methodologies for Quantification of Flavonoids and Total Phenols in Propolis
(Brazilian Chemical Soc, 2021-01-01)
Propolis is widely known for its important therapeutic activities. In its chemical constitution, there are several classes of secondary metabolites, such as simple phenols, carboxylic and cinnamic acids, coumarins, tannins ...
Paepalanthus spp: antimycobacterial activity of extracts, methoxylated flavonoids and naphthopyranone fractions
(2013)
Paepalanthus spp., Eriocaulaceae, are native plants from Brazil known as “sempre-vivas” (everlasting flowers). In this work, we evaluated the potential anti-mycobacterial activity of two methoxylated flavonoids (flavonoid ...
A partial least squares regression study with antioxidant flavonoid compounds
(Springer, 2006-06-01)
The quantitative structure-activity relationship of a set of 19 flavonoid compounds presenting antioxidant activity was studied by means of PLS (Partial Least Squares) regression. The optimization of the structures and ...
Dimorphandra mollis: Uma Alternativa como Fonte de Flavonóides de Ação Antioxidante
(2010-03-01)
Dimorphandra mollis fruits are rich in fiavonoids rutin and quercetin, which are compounds with high antioxidant activity and can be used to prevent diseases caused by free radicals. The aim of this study was to obtain an ...
High-performance liquid chromatographic quantification of flavonoids in Eriocaulaceae species and their antimicrobial activity
(2009-11-01)
Quantification of prepared samples by analysis using high performance liquid chromatography with DAD detection was developed to analyze rutin, 6-methoxyapigenin, and 6-methoxyapigenin-7-O-β-D-glucopyranoside isolated from ...

Research trends in flavonoids and health
(Elsevier Science Inc, 2018-05)
Herein we describe, based on some bibliometric data, how the field of research on flavonoids has evolved over the last 25 years. The number of papers on flavonoids has risen in an exponential manner over these years, much ...
(Iso)Flav(an)ones, chalcones, catechins, and theaflavins as anticarcinogens: Mechanisms, anti-multidrug resistance and QSAR studies
(Bentham Science Publishers, 2012-09)
Flavonoids have shown anticarcinogenic activity in cancer cell lines, animal models, and some human studies. Quantitative structure-activity relationship (QSAR) models have become useful tools for identification of promising ...
Metabolismo de Flavonoides por Spodoptera frugiperda e Anticarsia gemmatalis
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2019-08-19)
The soybean plant (Glycine max L. Merryl) produces a range of flavonoids as secondary metabolites, known to cause damage to herbivorous insects. However, Spodoptera frugiperda and Anticarsia gemmatalis (Lepidoptera: ...
