Manuifolin Q, an unusual 4-aryl-substituted isoflavan from Maackia tenuifolia.
Manuifolin Q (1), an unusual 4-aryl-substituted isoflavan, was isolated from the roots of Maackia tenuifolia. Its absolute configuration was determined as (3R,4R)-3,4-trans-7,2'-dihydroxy-4'-methoxy-4-[(2,4-dihydroxy-5-(1,1-dimethyl-2-propenyl)]-phenyl-isoflavan, on the basis of spectroscopic analysis.
