ABSTRACT
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.

Objective: To establish an inductively coupled plasma mass spectrometry (ICP-MS) method for the simultaneous determination of 16 inorganic elements of Mume Fructus, and the elements were analyzed and evaluated. Methods: ICP-MS was used to determine the content of 16 inorganic elements in the samples after microwave digestion. Principal component analysis (PCA) and correlation analysis were performed using SPSS21.0. Results: There were no differences in the types of inorganic elements in the samples of Mume Fructus, and the content of K, Ca, Mg, Na, Fe and B was abundant in the 16 elements. Through principal component analysis, 27 batches of samples from the same origin were all clustered together, indicating that the difference of inorganic element content was related to the ecological environment of the origin, but the difference between varieties was not obvious. The characteristic elements of Mume Fructus were Cu, Zn, Ca, Mg, and the results showed that the scores of samples from Sichuan was the highest. Conclusion: This study established an accurate and efficient method for the analysis and evaluation of inorganic elements in Mume Fructus from different habitats, which provided a scientific reference for the breeding, safety evaluation, and comprehensive utilization of Mume Fructus resource.
ABSTRACT
Objective:To observe the effect of Saposhnikoviae Radix-Mume Fructus containing-serum in regulating the phenotypic transformation of airway smooth muscle cells (ASMCs) proliferation model, in order to explore the mechanism of combined administration of "Saposhnikoviae Radix, Mume Fructus" in inhibiting airway remodeling, and reveal the compatibility mechanism of traditional Chinese medicine. Method:The proliferation model of ASMCs was established by platelet derived growth factor (PDGF) induction. The rats were given normal saline, Saposhnikoviae Radix-Mume Fructus, Saposhnikoviae Radix-Mume Fructus(15.425, 15.425, 30.85 g·kg-1·d-1) to prepare drug serum respectively. Four generations of logarithmic phase human bronchial smooth muscle cells (HBSMC) were collected and divided into blank control group, cell model group, normal rat serum group and normal rat serum cell model group, hormone intervention group, Saposhnikoviae Radix serum group, Mume Fructus serum group, Saposhnikoviae Radix-Mume Fructus serum group. The cells were given corresponding treatment. Immunofluorescence staining and Western blot were adopted to detect ASMCs deflating marks protein α-actin and osteopontin (OPN) expressions, and phenotypic transformation was observed; the levels of vascular endothelial growth factor(VEGF), transforming growth factor-β(TGF-β) and interleukin-6(IL-6) secreted by ASMCs were detected by enzyme linked immunosorbent assay (ELISA). Result:Compared with blank group and normal rat serum group, the fluorescence intensity and protein expression of α-actin in model group and normal rat serum cell model group were low, whereas the fluorescence intensity and protein expression of OPN were high, and the concentrations of VEGF, TGF-β and IL-6 increased significantly (Pβ and IL-6 (PConclusion:The combined administration of "Saposhnikoviae Radix-Mume Fructus" has an inhibitory effect on airway remodeling, which may be related to the inhibition of the transformation of ASMCs from contractile phenotype to synthetic phenotype, so as to reduce the release of active substances, such as VEGF, TGF-β and IL-6.
