In order to support the implementation of the Opinions on Improving the Quality of Traditional Chinese Medicine and Promoting the High-Quality Development of the Traditional Chinese Medicine Industry and fundamentally promote the high-quality development of Chinese materia medica(CMM) industry, this article analyzed the quality and safety issues arising during the transition of CMM from wild harvesting to cultivation. Root causes of these issues were identified, including changes in the habitats of medicinal plants caused by inappropriate field cultivation patterns, excessive use of chemical inputs such as fertilizers and pesticides, and shortened cultivation periods due to rising economic costs. To address the above issues, the following countermeasures and suggestions were proposed to advance the high-quality development of CMM:(1) comprehensively adjust the cultivation patterns, vigorously promote ecological cultivation of CMM, and ensure production quality and safety of CMM from the source;(2) strengthen the breeding of high-quality, stress-resistant CMM varieties, improve cultivation techniques to reduce the use of fertilizers and pesticides, and improve the quality and efficiency of ecological cultivation of CMM;(3) systematically design the production, operation, and supervision models for ecological cultivation of CMM, carry out demonstrations of "high quality with fair price", and ensure the sustainable development of ecological cultivation of CMM.

Prunus mume is an edible and medicinal material, and Mume Fructus is its processed product, which was first recorded in Shennong's Classic of Materia Medica(Shen Nong Ben Cao Jing). It is an effective drug for stopping diarrhea with astringents and promoting fluid production to quiet ascaris. By consulting the ancient herbal works of the past dynasties, modern codes, and other rela-ted literature, this paper sorted out the medicinal evolution of Mume Fructus, examined the ancient efficacy of Mume Fructus and the main indications, and summarized the inclusion of Mume Fructus in national and provincial standards. It is recorded in the ancient herbal works of the past dynasties that Mume Fructus can be processed by various methods such as roasting, stir-frying or micro-frying, stir-frying with charcoal, single steaming, steaming with wine, and steaming after soaking in wine or vinegar, and prepared into pills, powders, and ointments, which are used in the treatment of fatigue, diabetes, malaria, dysentery, ascariasis, and other diseases. Mume Fructus has been included in nine editions of Chinese Pharmacopoeia and 19 provincial and municipal preparation specifications. The processing method of Mume Fructus is determined, namely, clean P. mume should be softened by moistening in water or steaming and pitted. By reviewing the effects of processing on its chemical composition, pharmacological effects, and its modern clinical application, this paper identified the following issues. The ancient application methods of Mume Fructus are diverse but less commonly used in modern times, there is a lack of standardized research on the processing, and the research on the changes caused by the difference in Mume Fructus before and after processing is not deep. Therefore, it is necessary to further investigate the change pattern of its chemical composition before and after processing and its correlation between its medicinal activity to standardize the processing technology and provide a solid basis for the use of Mume Fructus in parts and its quality control.

Nitrogen fertilizer has been the long-lasting crucial component in cultivation of Chinese materia medica(CMM) and crops for its profound effects on enhancing the productivity. In consideration of its role in better production, intensive and excessive application of N fertilizer is often found in CMM cultivation. Therefore, firstly, this review summarized various concentrations of N application with regards to different CMM and districts from the literatures published in the last two decades. The recommended concentration of nitrogen application of forty seven CMM species were covered in this review. We found that the optimum rates of nitrogen fertili-zer for different medicinal plants species were varied in the range between 0-1 035.55 kg·hm~(-2). Most of the optimum rates of nitrogen fertilizer for CMM in published researches fell between 100-199 kg·hm~(-2). The optimum rate of nitrogen fertilizer is not only related to amount of nitrogen required for different medicinal plants but also to soil fertilities of different fields. In addition, we outlined the diffe-rent effects of proper and excessive nitrogen deposition on yield of CMM. Proper nitrogen deposition benefits the yield of CMM, howe-ver, excessive nitrogen use accounts for a decrease in CMM yield. We elucidated that nutritional content, water use efficiencies, and photosynthesis capacity were major influencing factors. Researches showed that proper nitrogen fertilizer could promote the water use efficiencies of plants and boost photosynthesis. Consequently, the yield of CMM can be enhanced after nitrogen deposition. However, negative effects of nitrogen fertilizer were also found on plant including producing toxic substances to the soil and causing severe pest damages. Lastly we analyzed the impact of N fertilizer application on secondary metabolites which accounts for a large part of active pharmaceutical ingredients of CMM. It usually caused an increase in nitrogen-containing secondary metabolites content and a decrease in non-nitrogen-containing secondary metabolites content respectively. The potential underlying mechanisms are the different synthetic pathways of these metabolites and the plant nutritional status. Synthesis of non-nitrogen-containing secondary metabolites like phenols can be inhibited after nitrogen application because of the competition of the same precursor substances between metabolites synthesis and plant growth. To sum up, impacts and mechanisms of nitrogen fertilizer on yield and quality enhancement of CMM were discussed in this review. Negative effects of excessive nitrogen application on CMM should be paid special attention in CMM cultivation and prescription fertilization based on the field soil quality is strongly recommended. Overall, this review aims to provides insights on improving the proper application of N fertilizer in the cultivation of CMM.

The pig bile powder, bovine bile powder, snake bile, sheep bile, goose bile powder, and bear bile powder were contained by the Chinese Pharmacopoeia. The bile power medicine has a long history in traditional Chinese medicine and definite effect. However, the medicine of bile powder(bile) are similar in morphology. Besides, many medicine lack specific microscopic identification characteristics and chemical characteristics. There is a risk of adulteration, especially when the fake medicine were mixed in authentic medicine, it is difficult to detection. The key to control the quality and ensures the clinical efficacy is the good or bad, true or false of the bile power medicine. The STR typing technology is a method that according to differential typing of PCR amplified lengths to compare and identify individual organisms. Based on the principle of STR typing, the easily, rapid DNA fingerprinting method to identify the bile power and adulteration was established.The original animal or bile powder of pigs, cattle, sheep, chickens, ducks, geese, snakes, bears, fish were collected, the 12 S-L1091/12 S-H1478 and 16 S-L3428/16 S-H3667 was obtained by sifted, the DNA fingerprinting of the bile power and adulteration was obtained by STR typing. Every species has different STR fingerprints, so different species can be identified. Besides, the fingerprints have both the authentic and fake's information, the adulteration of authentic and fake can be identified. Therefore, the method to identify the bile power and adulteration was achieved through the combination of two primers. The DNA fingerprinting method established in this study can also be used for other animal medicine.

Near-infrared (NIR) diffuse reflectance spectroscopy was used to analyze the impact of multi-class particle size of Chinese material medica (CMM) based on the spectral characteristics in overtone and combination region. Several types of CMM (60, 80, 100,120 mesh) were subjected to NIR spectra analysis. Spectral reproducibility was examined after sample repackage. The result showed that the effects of particle size on the NIR spectra were different according to different bands, in the combination region and first combination-overtone region. Spectroscopy intensity was proportional to the particle size and influence of particle size was greater as the wavelength increased. While in the second combination-overtone region, it was inversely proportional to particle size. To the sampling loading error, the result indicated that when the mesh number was larger than 60 mesh, the error was small. The appropriate particle size was clarified to guarantee the accuracy and reliability of NIR diffuse reflectance spectroscopy in CMM.

This paper aims to summarize the achievements during the implementation process of good agricultural practice (GAP) in Chinese Materia Medica (CMM), and on basis of analyzing the existing problems of GAP, to propose further implementation of GAP in TCM growing. Since the launch of GAP in CMM growing ten years ago, it has acquired great achievements, including: (1) The promulgation of a series of measures for the administration of the GAP approval in the CMM growing; (2) The expanded planting area of CMM; (3) The increased awareness of standardized CMM growing among farmers and enterprises; (4) The establishment of GAP implementation bases for CMM growing; (5) The improvement of theory and methodology for CMM growing; (6) The development of a large group of experts and scholars in GAP approval for CMM production. The problems existing in the production include: (1) A deep understanding of GAP and its certification is still needed; (2) The distribution of the certification base is not reasonable; (3) The geo-economics effect and the backward farming practices are thought to be the bottlenecks in the standardization of CMM growing and the scale production of CMM; (4) Low comparative effectiveness limits the development of the GAP; (5) The base of breeding improved variety is blank; (6) The immature of the cultivation technique lead to the risk of production process; (7) The degradation of soil microbial and the continuous cropping obstacle restrict the sustainable development of the GAP base. To further promote the health and orderly GAP in the CMM growing, the authors propose: (1) To change the mode of production; (2) To establish a sound standard system so as to ensure quality products for fair prices; (3) To fully consider the geo-economic culture and vigorously promote the definite cultivating of traditional Chinese medicinal materials; (4) To strengthen the transformation and generalization of basic researches and achievements, in order to provide technical support for the CMM production; (5) To deepen the understanding of GAP, to vigorously promote ecological planting and precision agriculture, in order to overcome the continuous cropping obstacle. The authors think that despite the fact that we are still facing with a huge array of management and technological problems, the GAP in the CMM growing has already enjoyed widespread support and showed great potential. In the future, with people's deeper understanding of GAP and the great progress of the science and technology, the GAP will constantly be fused with the theory, methodology and technology in the modern agriculture like precision agriculture, eco-agriculture and etc.
