摘要：
Extracts of Matricaria aurea flowers are shown to exhibit anticorrosive activity when used with mild steel in acidic media. A process is shown for obtaining such anticorrosive extracts from the flowers of M. aurea. In particular, certain methanolic, aqueous methanolic and water extracts, as well as ethyl acetate and n-butanol fractions, of M. aurea flowers are shown to demonstrate particular anticorrosive activity when used with mild steel in acidic media. An isolated flavonoid compound from M. aurea flowers, designated as apigenin-7-O-β-D-glucoside, is particularly useful for anticorrosive activity when used with mild steel in acidic media.
