Chemical constituents from two weed species of Spermacoce (Rubiaceae)

Spermacoce articularis and Spermacoce exilisare weeds commonly growing in wastel ands but widely used as traditional medicines. The separation works on the two plant species had been carried out using various solvents and chromatographic methods. The structures of the isolated compounds were determi...
