Cooperative Regulation of Flavonoid and Lignin Biosynthesis in Plants
, 2021Flavonoids and lignin are valuable phytochemicals derived from plant secondary metabolism and play important roles in regulating multiple plant developmental processes and signaling networks. The biosynthetic pathways leading to flavonoids and lignin are

Flavonoids are secondary products of plants that include thousands of compounds classified in several classes. Preclinical studies mainly carried out in rodents suggest that they may have a role in the prevention of immunoglobulin E (IgE) synthesis and mast cell degranulation. Interestingly, using animal models with allergic asthma, it can be concluded

In order to ascertain the role of dietary flavonoids as antioxidants in vivo it is necessary to understand the chemical nature of the absorbed forms in the circulation in vivo and how the multiplicity of research findings in vitro reflect the bioactivity of flavonoids in vivo. Only when we gain adequate information on the circulating forms can we begin

Enteric Disposition and Recycling of Flavonoids and Ginkgo Flavonoids
The Journal of Alternative and Complementary Medicine, 2003The objective of this study was to determine the intestinal and microbial disposition of flavonoids and how these disposition processes affect their enteric recycling.Studies were performed using a perfused rat intestinal model or using enrichment cultures and a pure isolate of Enterococcus avium (LY1).In the rat intestine, aglycones, such as quercetin
