[Chemical constituents from capitula of Eriocaulon australe ]
Objective:
To study the chemical constituents from the capitula of Eriocaulon australe.
Method:
The compounds were isolated and purified by column chromatography and their structures were determined through spectroscopic techniques (NMR)and physicochemical properties.
Results:
Six compounds were identified from capitula of Eriocaulon australe as (R)-semixanthomegnin( 1) ,tora-lactone-9-0-β-D-glucopyranoside(2), ( - ) -semivioxanthin-9-0-β-D-glucopyranoside( 3) ,4-ketopinoresinol(4) ,β-daucosterol (5) and 3,3'-dihydroxy-4,4'-dimethoxybiphenyl(6).
Conclusion:
Compounds 1 ~ 6 are isolated from this plant and compounds 3 ~ 6 are ob- tained from Eriocaulon genus for the first time. Compound 1 shows DNA scission activity.
