Beschreibung
Taxifolin, a chemical substance extracted from pine plants such as larch
and Douglas fir. It belongs to the bioflavonoid pseudo-vitamin P, and
its scientific name is dihydroquercetin. Japanese scholar Fukui first
isolated it from the leaves of conifers (Chamaecyparis obtusa), and its
biological activity was subsequently discovered and confirmed.
Chemische Eigenschaften
Yellow Solid
Verwenden
An antioxidant flavenoid.
Definition
ChEBI: A taxifolin that has (2R,3R)-configuration.
Application
Taxifolin is a flavonoid commonly found in onion, milk, French maritime
pine bark and Douglas fir bark. It is also used in
various commercial preparations like Legalon?, Pycnogenol?, and
Venoruton?. This review focuses on taxifolin’s biological activities and
related molecular mechanisms. It showed promising pharmacological
activities in the management of inflammation, tumors, microbial
infections, oxidative stress, cardiovascular, and liver disorders. The
anti-cancer activity was more prominent than other activities evaluated
using different in vitro and in vivo models. Further research on the
pharmacokinetics, in-depth molecular mechanisms, and safety profile
using well-designed randomized clinical studies are suggested to develop
a drug for human use.
Allgemeine Beschreibung
Taxifolin is a plant flavonoid, which may find applications in the treatment of coronary heart disease, angina pectoris, cerebral thrombosis, cerebral infarction and sequelae.
