ABSTRACT
A chemometric technique, heuristic evolving latent projection (HELP), was applied to analyze the data obtained from high performance liquid chromatography coupled with the diode array detection (HPLC-DAD) for a traditional Chinese medicinal herb, Cordyceps sinensis. Based on this method, the water soluble components, nucleosides in Cordyceps sinensis were identified. Ten and eleven volatile components were identified from the fungal and larvae parts of Cordyceps sinensis sample, respectively. As compared with the conventional method, HELP was found to be suitable for quantitative analysis of complex real systems such as Chinese medicinal products.
