Chemistry

The phenolic compounds 2,4,6-trihydroxybenzoic acid-4-O-2′,3′,4′,6′-tetraacetylglucoside; 2,4,6-trihydroxybenzoic acid-4-O-2′,3′,6′-triacetylglucoside; 2,4,6-trihydroxybenzoic acid-4-O-3′,4′,6′-triacetylglucoside; 3-O-p-coumaroylshikimic acid; 2--5-hydroxy-7-methoxychromone; kaempferol; and kaempferol-3-O-β-d-glucoside can be isolated from the methanolic extract of fronds of Phegopteris connectilis.
