ABSTRACT
Research has demonstrated that many chemical constituents dominated by piperidine alkaloids and flavonoids, such as lobelanidine, lobeline, and lobelanine, have been obtained from Lobelia chinensis Lour. Experimental studies and clinical applications have also indicated that L. chinensis possesses a number of pharmacological activities (e.g., diuretic, choleretic, breathing excitement, anti-venom, anti-bacterial, and anticancer). This paper focuses on the properties, chemical constituents, and anticancer activity of L. chinensis to clarify the connection among them, and identify the active anticancer compounds. This work serves as the foundation for further research and development of L. chinensis.

Hot-melt extrusion (HME) is mainly used to enhance the dissolution rate and bioavailability of poorly water soluble drugs. It has many advantages, such as simple process, continuous operation, high efficiency, on-line monitoring and so on. HME provides an innovative approach, which has been concerned by pharmaceutical workers, for preparation of solid dispersion abroad. This article reviews recent advances on preparation of solid dispersion by HME in preparation processing, carrier materials and quality evaluation in order to further promote and apply HME in preparation of solid dispersion.
