Abstract

Three new sodium salts of iridoid acids, deacetylasperulosidic acid sodium salt (1), teneoside D (2), and teneoside E (3) were isolated from the leaves of Hedyotis tenelliflora Blume (Rubiaceae), together with seven known iridoids, 6α-hydroxygeniposide (4), 6β-hydroxygeniposide (5), 6- O-methyldeacetylasperulosidic acid methyl ester (6), 6- O-methylscandoside methyl ester (7), 6α-methoxygeniposidic acid (8), daphylloside (9), and mollugoside methyl ester (10). Their chemical structures were elucidated by 1D and 2D NMR spectroscopy, as well as HR-ESI-MS analysis.
