Resumo

Kalanchoe delagoensis (also known as Bryophyllum delagoensis and Kalanchoe tubiflora) is a Crassulaceous plant used for healing wounds and dermatitis. The species showed antitumor potential in recent pharmacological surveys. The present study aimed to isolate the phenolic compounds from the aqueous extract of K. delagoensis flowers. Here, we report the occurrence of the flavonoids corniculatusin 3-O-β-glucopyranoside 1 (8-methoxyquercetin 3-O-glucoside), kaempferol 3-O-β-glucopyranoside 2, quercetin 3-O-β-glucuronopyranoside 4, and gallic acid 3. Our original results contribute to the knowledge of the chemical composition of K. delagoensis.
