Barrigenol triterpenes from the husks of Xanthoceras sorbifolia Bunge and their antitumor activities
Publikováno v:
RSC Advances. 6:27434-27446
Barrigenol-like triterpenoids containing angeloyl residues in their structures are unusual natural products. To discover the chemical constituents responsible for the antitumor activity of Xanthoceras sorbifolia Bunge, the present study was carried o
