Abstract:
AIM: To optimize the milling and extraction rate for Naolisu Granules (Rhizoma Acori Tatarinowii, Radix Notoginseny, Pheretima Radix et Rhizoma Rhei, Radix Curcuma, Radix Ginserg Rubra, etc.). METHODS: The granularity of powder was determined by different micropowder processes. The process was studied by orthogonal design with the content of volatile oil, the yield of extract and the content of emodin. RESULTS: The optimum process of milling was that coarse powder was micropulverized for 20 min at -8℃ ～ -12℃ . The optimum extraction of volatile oil was distillated for 4 hs after volatile medical materials were macerated for 1h with 7 times amount of water. The optimum process of percolation was percolated by 300mL of 75% alcohol with 3.0mL?kg -1 ?min -1 after the medical material powders were macerated for 6 hs. CONCLUSION: These optimum processes are suitable for preparation of Naolisu Granules.
