Abstract: |
Ten compounds including Kalamycin (1), Medermycin (2), Menoxymycin-B (3), spatozoate (4), anthranilic acid(5), 3-indolylethanol(6), 1-acetyl-β-carbolin(7), p-hydroxyphenylethyl alcohol(8), indole-3-acetic acid(9), and indol-3-carboxylic acid(10) were isolated from the ethyl acetate extract of a marine-derived Streptomyces sp. L211 by using normal phase silica gel, Sephadex LH-20 chromatography and preparative thin layer chromatography. Their structures were identified by spectroscopic methods including 1H-NMR, 13C-NMR and EIMS. |
