ABSTRACT
Objective:
To study the chemical constituents of ethyl acetate fraction in 80% ethanol reflux extract from the aerial part of Gynura divaricata.Methods:
Column chromatographic techniques were applied to isolate and purify the chemical constituents. The chemical structures of the constituents were elucidated on the basis of mass properties and NMR spectral data.Results:
Fourteen compounds were isolated and their structures were determined spectroscopically as succinic acid (1), methyl succinate (2), ethyl succinate (3), ethyl methyl succinate (4), 4-hydroxybenzoic acid (5), salicylic acid (6), isovanillic acid (7), p-coumaric acid (8), esculetin (9), quercetin (10), kaempferol (11), isoquercitrin (12), astragalin (13), and rutin (14).Conclusion:
