ABSTRACT
The root of Hedyotis capitellata Wall. ex G.Don var. mollis Piere ex Pit. Rubiaceae, has been investigated chemical constituents. The roots contained alkaloids, saponin, tannin, anthranoid. Of these, 3 compounds were purified and their IR,UV, EIMS, NMR spectra were determined and showed that: They were Hedyocapitine, Capitelline and Di- (2’- ethyl-1’-hexyl) phthalate (or1,2- benzenedicarboxylic acid, Di- (2’-ethyl-1’-hexyl) ester).
