Abstract: Chuanxiong, as a medicinal plant, has been demonstrated useful for the treatment of cardio-cerebrovascular diseases in China. The physicochemical characterization of Chuanxiong particles was greatly influenced by ultrafine pulverization. To study the physicochemical characterization of Chuanxiong, the raw plant material of Chuanxiong was ground to 6 μm particles by HSCS (High Speed Centrifugal Sheering) pulverizer. The micron particles were characterized by optical microscope and SEM. Ferulic acid is one of active ingredients of Chuanxiong, and its extraction yield was determined to evaluate the chemical characterization of Chuanxiong powder. Ferulic acid was analyzed by HPLC (High Performance Liquid Chromatography). The results showed that after ultrafine pulverization, the plant cell walls were broken into pieces and the extraction yield of ferulic acid was increased by 7.739% compared with the normal particles.

Abstract: Qianghuo, as a medicinal plant , has been demonstrated useful for the treatment of ache diseases in China. The physicochemical characterization of Qianghuo particles was greatly influenced by ultrafine pulverization. To study the physicochemical characterization of Qianghuo, the raw plant material of Qianghuo was ground to 5 μm particles by HSCS (High Speed Centrifugal Sheering) pulverizer. The micron particles were characterized by optical microscope and SEM. Ferulic acid is special chemical component of Qianghuo, and its extraction yield was determined to evaluate the chemical characterization of Qianghuo powder. Ferulic acid was analyzed by HPLC (High Performance Liquid Chromatography). The results showed that after ultrafine pulverization ,the plant cell walls were broken into pieces and the extraction yield of ferulic acid was increased by 30.24% compared with the original particles.

Abstract: Honghua has been demonstrated useful for promoting blood circulation and stopping pain. The physicochemical characterization of Honghua powders was greatly influenced by ultrafine pulverization. To study the physicochemical characterization of Honghua, the raw plant material of Honghua was ground to powders by high speed centrifugal sheering (HSCS) pulverizer. The micron powders were characterized by laser scattering granulometric analyzer and scanning electron microscope (SEM). Hydroxysafflor yellow A is one of active ingredients of Honghua, and its dissolution speed was determined to evaluate the chemical characterization of Honghua powder. The results showed that after ultrafine pulverization, dissolution speed of hydroxysafflor yellow A was increased by 28.6% compared with the normal powders
