Astragalin can be isolated in nature from some plants such as from Phytolacca americana L. or through the methanolic extract of the fronds of the fern Phegopteris connectilis (Michx.) Watt or also from Polygonum aviculare L., 1753.
However it is present in other plants and can also be found in wine.
Astragalin is an anti-inflammatory flavonoid that, according to some studies, can improve airway thickening and alveolar destruction by blocking allergic inflammation in the airways. Therefore, astragalin may be a therapeutic agent to antagonize asthma and obstructive pulmonary disease.
