OBJECTIVE
To study the chemical constituents contained in ethanol extracts from aerial parts of Emilia sonchifolia.
METHODS
The compounds were separated and purified with various chromatographic techniques, and their structures were identified on the basis of physicochemical properties and spectral data.
RESULTS
Fifteen compounds were separated from ethyl acetate fraction of 90% ethanolic extract and identified as rhamnetin (1), isorhamnetin (2), quercetin (3), luteolin (4), tricin-7-O-beta-D-glucopyranoside (5), 8-(2"-pyrrolidinone-5"-yl) -quercetin (6), 5, -2', 6'-trihydroxy-7, 8-dimethoxyflavone-2'-O-beta-D-glucopyranoside (7), succinic acid (8), fumaric acid (9), p-hydroxybenzoic acid (10), 4-hydroxy isophthalic acid (11), 3, 4-dihydroxycinnamic acid (12), esculetin (13), isowedelolactone (14) and uracil (15), respectively.
CONCLUSIONS
All compounds except compound 3 were separated from this genus for the first time.
