[ XXXX from Cordyceps kyushuensis and the distribution of two active components in its different parts].

@entity2642 @entity2353 @entity859 @entity1568 @entity5 @entity2441 @entity3440 @entity1883 @entity7159
AIM: To rapidly separate and determine the @entity2642 from natural and cultured Cordyceps kyushuensis Kob., and to compare the content of @entity1883 and @entity859 in different parts of Cordyceps kyushuensis Kob., which are the main @entity2353 active components in medicinal fungus belonging to Cordyceps (Fr.) Link. METHODS: The @entity2642 were separated and determined by the high performance capillary zone electrophoresis (CZE). Beckman P/ACE system MDQ apparatus equipped with a PDA detector and a uncoated fused- @entity3440 capillary (41 cm x 45 microns ID, 30 cm effective length) were used. The experimental conditions were as follows: the running buffer was borax solution (adjust to pH 9.4 with @entity7159 ), applied voltage was 20 kV, operated temperature was 20 degrees C and the detector wavelength was 258 nm. The content of @entity1883 and @entity859 in the fruiting body, stroma and host worm of natural and cultured C. kyushuensis were respectively investigated and quantitatively analyzed. RESULTS: There are at least 8 kinds of @entity2353 or @entity1568 base in Cordyceps kyushuensis Kob. The content of @entity1883 which is a bio-active substance with anti- @entity5 activity in C. kyushuensis is significantly higher than that in @entity2441 and C. militaris, and furthermore the @entity1883 in the cultured C. kyushuensis is notably higher than the natural one. @entity859 was mainly found from the stroma of C. kyushuensis, While the @entity1883 content is high in the stroma of both natural and cultured C. kyushuensis as well as in the host worm of the cultured one. CONCLUSION: There are some differences about the @entity2353 components between the natural and cultured C. kyushuensis and between the different parts of them. With a high @entity1883 content, C. kyushuensis should have a considerable medicinal potential.
