Abstract
Objective:
To study the chemical constituents from Aquilegia ecalcarata.
Method:
Compounds were isolated with silica gel and polyamide chromatography and their structures were determined by spectral analysis and chemical evidence.
Result:
Five compounds were obtained and identified as beta-sitosterol, isoorientin-7-O-glucoside, isovitexin-4'-O-glucoside, isovitexin-2'-O-rhamnoside, luteolin-7-O-glucoside.
Conclusion:
All the compounds were isolated from this plant for the first time.
