title: Three polyoxygenated cyclohexenes from Uvaria calamistrata.
abstract: Three new polyoxygenated cyclohexenes, named uvacanols F, G, H (1-3), were isolated from the roots of Uvaria calamistrata (Annonaceae). Their structures were determined to be 2-acetoxyl-5-chlorine-benzoyloxymethylcyclohex-1 (6)-ene-4-ol-3-benzoate (1), benzoyloxy-methylcyclohex-1 (6)-ene-2,3,4-triols-5-benzoate (2), 3-acetoxyl-benzoyloxymethylcyclohex-1 (6)-ene-4,5-diols-2-benzoate (3) by spectroscopic methods and chemical derivatization.
