Isolation and identification of the chemical constituents from Cephalomappa sinensis

Aim To study the chemical constituents of Cephalomappa sinensis(Chun et How) Kosterm.Methods The constituents were isolated and purified by column chromatography,and their structures were identified by physicochemical data and spectral data.Results Six compounds were isolated from the ethanol extract of the twigs of Cephalomappa sinensis,and their structures were elucidated as lupeol(1),acetylaleuritolic acid(2),gallic acid(3),(3S,5R,6S,7E,9R)-3,6-dihydroxy-5,6-dihydro-β-ionol(4),(3β,4α,5α,6αH,7E,9S)-3,4-dihydroxy-5,6-dihydro-β-ionol(5),and scopoletin(6),respectively.Conclusion Compounds 1,4,and 5 are isolated from this plant for the first time.
