title: Structural determination of two new triterpenoids biotransformed from glycyrrhetinic acid by Mucor polymorphosporus.
abstract: Five hydroxylated derivatives of glycyrrhetinic acid by Mucor polymorphosporus were isolated. Among them, 6beta, 7beta-dihydroxyglycyrrhentic acid (2) and 27-hydroxyglycyrrhentic acid (3) are new compounds. Their chemical structures were identified by spectral methods including 2D-NMR.
