Chrysin(Cas 480-40-0) Usage
Chemical Description |
Chrysin is a flavone found in honey and propolis. |
Prepration |
The main sources of chrysin are honey and propolis, of which the content of chrysin in honey is 5.3 mg/kg?and that in propolis is 28 g/L. In addition, chrysin is also found in various vegetables, fruits, herbs, and even mushrooms?[10]. Another source of populin is an endophytic fungus Chaetomium globosum, which is related to Chaetomorpha media from India. In addition, chrysin exists in the form of glycosides in walnut, walnut skin, walnut flower and pericarp passion fruit, and in the form of 6-c-arabinoside-8-c-glucoside or glucuronic acid ester in Pinellia ternata. |
