Chemical constituents in carpophore of Xanthoceras sorbifolia

Objective To study the chemical constituents in ethanol extract from the carpophore of Xanthoceras sorbifolia and explore a new potential part.Methods The constituents were isolated by macroporous resin and silica gel column chromatography and their structures were elucidated by the phisi-cochemical properties and spectral evidence.Results Compounds Ⅰ-Ⅵ wre obtained and their structures were identified as 21-angeloyl-24-hydroxy-R1-barrigenol(Ⅰ),23-hydroxybetulinic acid(Ⅱ),3β,23-dihydroxy-lup-20(29) en-28-oic acid-3-caffeate(Ⅲ),22,23-dehydroxy-α-chondrillasterone(Ⅳ),3-oxotirucalla-7,24-dien-21-oic(Ⅴ),and α-spinasterol-3-O-β-D-glucopyranoside(Ⅵ),respectively.Conclusion Compound Ⅰ is a new natural product and compounds Ⅱ-Ⅳ are isolated from the plants of Xanthoceras Bunge for the first time.
