Abstract:Six compounds were isolated from the leaves of Antiaris toxicaria. On the basis of spectral data, they were identified as (3S,5R,6S,7E,9R)-3,6-dihydroxy-5,6-dihydro-β-ionol (1), (5R)-4,5-dihydroblumenol A (2), quercetin-3-O-β-D-glucopyranoside (3), narcissin (4), kaempferide-3-O-β-D-glucopyranosdie (5) and epoxyconiferyl alcohol (6). All the compounds were isolated from Antiaris toxicaria for the first time.
