Abstract:
AIM: To construct suitable quality standard of evaluating antipyretic effect of 4 herbs,Bupleurum,Flos Lonicerae Japonicae,Radix Isatidis and Fructus Forsythiae. METHODS: Extracts,essential oils and its mixtures of extract and oil of above herbs,plus Ibuprofen Suspension,were used for antipyretic experiment on rats.Principal Component Analysis and Canonical Correlation Analysis were adopted as evaluation tools to examine the correlation between pharmacological effect and UV spectra of herb's chemicals,from which spectral marker of potential reliability for evaluating antipyretic effects of samples could be constructed. RESULTS: Antipyretic effect sequencing of UV spectral canonical variables was consistent with that of the four herbs. CONCLUSION: The first canonical variable U1 expressed by principal component scores of UV spectra of herbs could be used as spectral marker for evaluating antipyretic effects of the four herbs.
