[Study on Chemical Constituents of Panzeria alaschanica].

Objective: To study the chemical constituents of the ethyl acetate extract from Panzeria alaschanica.

Methods: The chemical constituents of ethyl acetate extract from Panzeria alaschanica were isolated and purified by silica gel. Their structures were i- dentified by means of spectra.

Analgesic effects and structural elucidation of two new flavone C-glycosides from Artemisa sacrorum.

The present study was designed to isolate and characterize the analgesic compounds of Artemisa sacrorum Ledeb. The EtOAc crude extracts from the aerial parts of Artemisa sacrorum Ledeb were separated by chromatography and the structures of new compounds were elucidated based on spectral analyses. Analgesic activities of the isolated compounds were assessed in rats with hot plate test and paw pressure assay.
