| Description | The phytochemical analysis of a methanolic extract from Helichrysum petiolare Hilliard & B. L. (Asteraceae) confirmed the content of phenylpropanoids and flavonoids. Five secondary metabolites were isolated using preparative HPLC, namely coumarin scopolin (1), 3-chlorogenic acid (2), caffeic acid-hexose derivative (3), dicaffeoylquinic acid (5), and the flavonoid isoquercitrin (4). These compounds were identified from this species for the first time. Only dicaffeoylquinic acid was able to inhibit Escherichia coli CCM 7929 at the concertation of 512 µg • mL–1 in a screening of antibacterial activity. |
