Experimental research on molluscicidal effect of endophyte JJ18 from Pseudolarix amabilis / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To research molluscicidal effect activity, active components and stable passage of endophyte JJ18 from Pseudolarix amabilis and examine the possibility for practical application.</p><p><b>METHOD</b>Molluscicidal effect test was performed according to the immersion test method suggested by WHO.</p><p><b>RESULT</b>Immersion test with JJ18 broth showed that the active components were extracellular moiety of the broth and that 10% concentration solution could kill nearly 90% snail immersed after 72 h, the salified broth has favourable thermostabily and photostability and showed that JJ18 has stable passage and its active components concentrate in the extract of n-butanol.</p><p><b>CONCLUSION</b>The metabolite of endophyte JJ18 has activity for molluscicidal effect and potential for application.</p>
