Abstract:

Fifteen compounds were isolated from the twigs and leaves of Caesalpiniaenneaphylla. Their structures were identified to be: (E)-3-(4-hydroxybenzylidene)- 5,7-dihydroxychroman-4-one (1), 8-methoxybonducellin (2), (E)-3-(3,4- dihydroxybenzylidene)-5,7-hydroxychroman-4-one (3), 2′,4′-dihydroxychalcone (4), oxyfadichalcone B (5), 7-hydroxyflavonone (6), pinocembrin (7), kaempferol (8), quercitrin (9), kaempferol 3-O-α-L-rhamnopyranoside (10), quercetin 3-O-α-D-arabinoside (11), trans-2,3-diacetoxy-1-[(benzoyloxy)methyl]-cyclohexa-4,6-diene (12), 3-hydroxybenzyl benzoate (13), 2-acetoxybenzyl benzoate (14), and glutinol (15). All the compounds were isolated from C. enneaphylla for the first time.

Key words: Leguminosae, Caesalpinia enneaphylla, Homoisoflavonoid
