摘要

To investigate the chemical constituents from the branches and leaves of Cupressus duolouxiana native to China in order to obtain a more comprehensive understanding of its effective components.Compounds were isolated and purified by silica gel column chromatography. They were identified and structurally elucidated by spectral analysis.Six compounds were isolated from the ethanolic extracts of Cupressus duolouxiana, which were identified as (7S,8S)-3-methoxy-3',7-epoxy-8,4'-oxy-neoligna-4,9,9'-triol (I), kaempferol (II), quercetin (III), juglanin (IV), quercetin-3'-methoxy-3-O-alpha-L-arabinofuranoside (V) and avicularin (VI).All compounds are obtained from this plant for the first time.
