Cluster analysis on hypocrellin A content in anamorphs of Shiraia bambusicola / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>By examining the colony growth rate, colony texture, substrate mycelium color and separation method of 40 anamorph strains of Shiraia bambusicola to investigate the relationship between these indexes and content of hypocrellin A.</p><p><b>METHOD</b>In UV-spectrophotometry and microscopic observation were applied in the experiments. The results were analyzed by the clustering and variance analysis.</p><p><b>RESULT</b>SPSS clustering analysis showed that the colony characters of S. bambusicola anamorph strains had significant differences with hypocrellin A content.</p><p><b>CONCLUSION</b>In the tested conditions, substrate mycelium color of S. bambusicola anamophs has the most distinct correlation with the yield of hypocrellin A.</p>
