| measurement of cordycepin and adenosine in stroma of cordyceps sp. by capillary zone electrophoresis (cze). | capillary zone electrophoresis (cze) was used to separate cordycepin and adenosine, and determine their concentration in stroma of cordyceps sp. these two active components of natural and cultured cordyceps kyushuensis were quantitatively analyzed and compared with those of cultured cordyceps militaris. the results showed that the cze method is a simple, rapid and sensitive method for the measurement of cordycepin and adenosine with good repeatability. | 2002 | 16233320 |
| determination of essential and toxic elements in cordyceps kyushuensis kawam by inductively coupled plasma mass spectrometry. | in this study, a total of 20 elements (essential, non-essential and toxic): lithium (li), sodium (na), potassium (k), gallium (ga), magnesium (mg), zinc (zn), iron (fe), copper (cu), manganese (mn), vanadium (v), chromium (cr), nickel (ni), cobalt (co), molybdenum (mo), selenium (se), barium (ba), tin (sn), arsenic (as), lead (pb) cadmium (cd) and mercury (hg) in natural and cultured cordyceps kyushuensis have been determined by means of inductively coupled plasma mass spectrometry (icp-ms). cul ... | 2013 | 23102516 |
| [analysis and evaluation of different radial parts of cordyceps kyushuensis by fourier transform infrared spectroscopy]. | fourier-transform infrared spectroscopy (ftir) and second derivative spectra were used to analyze and evaluate the different parts of cordyceps kyushuensis kob in the present work. the results showed that c. kyushuensis contained proteins, polysaccharides, nucleosides, lipids and other active ingredients, the single-dimensional ir spectra of the various parts were highly similar, the similarity coefficient between the cultured stroma and medium reached up to 0.992 7, and the natural stroma was m ... | 2011 | 22097840 |
| [nucleoside from cordyceps kyushuensis and the distribution of two active components in its different parts]. | to rapidly separate and determine the nucleosides from natural and cultured cordyceps kyushuensis kob., and to compare the content of cordycepin and adenosine in different parts of cordyceps kyushuensis kob., which are the main nucleoside active components in medicinal fungus belonging to cordyceps (fr.) link. | 2003 | 14730920 |
