1Research Centre for Development and Application of Natural Resources, Yunnan University, Kunming 650091.
Abstract
Objective:
To study chemical elements of the inflorescence of Elsholtzia blanda produced in the southwest of Yunnan.
Method:
Using chemical techniques and spectroscopic analysis.
Result:
Four flavonoid glucosides from the water extract of E. blanda were isolated and identified as isoastragalin(I), luteolin-7-glucoside(II), luteolin-3'-glucoside(III) and lutelin-7-galactoside(IV).
Conclusion:
All the four flavonoid glucosides were isolated from the plant for the first time.
