In the present study, 14 phenolic glycosides, including one new neolignan glycoside, iodescirrhoside A (1), three new flavonol glycosides, iodescirrhosides B-D (2-4), and 10 known metabolites were obtained from the methanol extract of Iodes cirrhosa leaves. Structural elucidation was performed by interpretating the 1D- and 2D- NMR, HR-ESI-MS, and CD spectra in comparison with literature data. All compounds were noncytotoxic to LU-1, HepG2, MCF-7, SK-Mel-2, and LNCaP cancer cell lines. Compound 11 significantly inhibited the growth of E. faecalis. In contrast, weak inhibition was observed for 1-9 and 14 against E. faecalis, for 1, 6-8, and 11 against S. aureus, for 6 and 13 against B. cereus, and 2, 4, and 6-9 against C. albicans.
