Abstract:Six compounds have been isolatea from the branch of Davidia involucrata Baill which is native to China. Their structures were identified as taraxerone (D1), taraxerol (D2), β-sitoste- rol (D3), 3′-O-methyl- 3, 4-O, O-methylideneellagic acid (D4), 3, 3′, 4-5-trimethylellagic acid (D5) and ellagic acid (D6) by means of chemical methods and IR 1H-NMR, MS, respectively.
