Abstract
From the aqueous acetone extract of burweed fruit, a new thiazinedione and four known phenolic compounds were isolated. The phenolics were identified as caffeic acid, potassium 3-O-caffeoyl quinate, 1,5-di-O- caffeoylquinic acid and 1,3,5-tri-O-caffeoylquinic acid. Based on 2D-NMR experiments and X-ray analysis, the thiazinedione was determined to be 7- hydroxymethyl-8,8-dimethyl-4,8-dihydrobenzo[1,4]thiazine-3,5-dione and named xanthiazone.
