Objective: To study the taxonomy and distribution of Chinese medicinal centipedes.

Methods: The species of Chinese medicinal centipedes were investigated in the light of their morphology. According to the feature of life, the distribution of centipedes were explored.

The Effect of Ultrafine Process on the Dissolution, Antibacterial Activity, and Cytotoxicity of Coptidis rhizoma.

Background: The dosage of herb ultrafine particle (UFP) depended on the increased level of its dissolution, toxicity, and efficacy.

Objective: The dissolution, antibacterial activity, and cytotoxicity of Coptidis rhizoma (CR) UFP were compared with those of traditional decoction (TD).

Materials And Methods: The dissolution of berberine (BBR) of CR TD and UFP was determined by high-performance liquid chromatography.
