RESUMEN

One new sodium salt of an iridoid acid, sodium 6-O-methyldeacetylasperulosidate (1) and one new heterocyclic compound, 1,3,6-trimethylpyrano[2,3- d]imidazole-2,5(1H,3H)-dione (2) were isolated from Hedyotis lindleyana Hook. (Rubiaceae), together with seven known compounds, oleanolic acid (3), ursolic acid (4), teneoside D (5), 6ß-hydroxygeniposide (6), deacetylasperulosidic acid sodium salt (7), liquiritin (8), and 3,3',4'-tri-O-methylellagic acid (9). The structures were established by spectroscopic (1D, 2D NMR) and HR-ESI-MS analysis, as well as by comparison with data reported in the literature.
