The antileishmanial activity assessment of unusual flavonoids from Kalanchoe pinnata

The present study reports the identification and the antileishmanial profile of unusual flavonoids from Kalanchoe pinnata: kaempferol 3-O-α-l-arabinopyranosyl (1 → 2) α-l-rhamnopyranoside (1), quercetin 3-O-α-l-arabinopyranosyl (1 → 2) α-l-rhamnopyranoside (2) and 4′,5-dihydroxy-3′,8-dimethoxyflavone 7-O-β-d-glucopyranoside (3).
