Phyllanthus emblica is a kind of traditional medicine and medicinal and edible plant, with rich variety resources and high development value. It is a key poverty alleviation variety in China at present. As P. emblica processing industry is rising gradually in recent years, in order to fully develop and utilize its industrial resources, this paper systematically introduces current comprehensive development and utilization of P. emblica, discusses the problems in P. emblica processing industry, and puts forward comprehensive development and utilization strategies and industrial models in terms of cultivation, breeding, grading, quality evaluation and waste recycling, so as to provide a certain reference for promoting the high-quality development of P. emblica industry in China.

Based on the principle of particle design, the powder of Xiaojin Pills was prepared, and the quality uniformity was investigated by means of powder characterizations and content uniformity. By studying the mixed crushing rules of the classified materials and the design principle of the powder particles of Chinese medicine, the powder of the Xiaojin Pills was prepared. At the same time, the manmade mixed powder and the control powder prepared by pharmacopoeia were prepared. The mixed homogeneity of the three powders was evaluated by particle size distribution and color difference. The GC-MS and LC-MS/MS were used to study the homogeneity of their contents. The best preparation process of particle design powder is:materials easily crushed are smashed for 50 min in the vibrating ultrafine mill with -15℃, then add the materials difficultly crushed into the mill and let them crushed together for 3 min. The particle size range of manmade mixed powder was the largest with the particle size difference being more than 100 microns, the RSD value being 26.07%. The particle size range was more than 50 microns in the powder prepared by pharmacopoeia, and the RSD was nearly 15%. The difference in particle size was only around 4 μm and the RSD value was 3.18%. The color difference test showed that the composite chromatism (dE*) value of the powder prepared by pharmacopoeia was the largest for the RSD was 84.56%. The RSD of manmade mixed powder and the powder prepared by Pharmacopeia were 53.83% and 32.83%, respectively. The RSD value of the particle designed powder's muscone content is about 50% of the other two kinds of powders. The contents of 10 components in powders were determined by LC-MS/MS. The RSD values of the particle designed powder were much smaller than other two kinds of powders. Results indicate that the uniformity of the particle designed powder is better than other two kinds of powders. Chinese medicine particle design technology can effectively improve the uniformity of traditional Chinese medicine powder.
