    Five new iridoids from Patrinia rupestris.[Pubmed: 17193308 ]
    Five new iridoids, namely rupesin A, rupesin B, rupesin C, rupesin D, Rupesin E (1-5, resp.), together with six known iridoids, 6-11, were isolated from the roots of Patrinia rupestris. Their structures were elucidated by spectroscopic methods including IR, UV, MS, and 1D- and 2D-NMR experiments, and comparison with data of known analogues. Compounds 4 and 11, compounds 1, 2, 5(Rupesin E), 6, 8, 9, and 10, and compounds 3, 4, and 8 showed significant antibacterial activities against Bacillus subtilis, Escherichia coli, and Staphylococcus aureus, respectively.
