Separation, purification and structural identification of an active nematicidal component from the fermentation broth of Endophytic streptomyces I07A-01824 from Mangrove ecosystem
Abstract：Objective To establish an efficient in vitro model for screening of new nematicidal compounds, and to separate, purify and identify the structure of an active nematicidal component from the fermentation broth of Endophytic actinomycets I07A-01824.
Methods Silica gel column chromatography and HPLC were used to separate and purify the active component. Its structure was identified by spectroscopic analyses.
Results The active component was purified and its structure was identified as an unsaturated fatty acid-tetradeca-5,8-dienoic acid. It displays the cytotoxic activity to Caenorhabditis elegans at 27.3 mg/L. Its LC50 is 162.8 mg/L in 24 h.
Conclusions The unsaturated fatty acid was first isolated from the strain of Endophytic actinomycets with nematicidal activity.
