Isolation and identification of chemical constituents from the rhizome of Belamcanda chinensis(L.) DC.

Objective To isolate the chemical constituents and elucidate their structures from the rhizome of Belamcanda chinensis(L.) DC.Methods The compounds from the ethanol extraction were isolated by silica gel,polyamide,Sephadex LH-20 and recrystallization,and their structures were identified by the spectral analysis and chemical evidence.Results Nine compounds were obtained and elucidated as:Irisfloretin(1),β-daucosterol(2),dichotomitin(3),irigenin(4),tectorigenin(5),β-sitosterol(6),apocynin(7),uridine(8),and cycloartanol(9).Conclusions Compounds 8 and 9 are isolated from the Belamcanda for the first time.
