RESUMO
Traditional Chinese medicine (TCM) processing is the summary of long-term clinical experience, processing can change the property, taste and meridian of TCM, achieve the purpose of reducing toxicity and increasing efficiency, to ensure the safety of clinical medication. This paper summarizes the research advance of salt processing in recent years from the aspects of the types of excipients, salt processing methods, salt processing purpose and the influence of salt process on the chemical composition, pharmacodynamic effect and in vivo behavior of TCM, and analyzes and discusses the shortcomings of the current research, so as to provide ideas for the further research and development of salt processing of TCM. The literatures were classified and summarized by consulting the scientific database (such as SciFinder Scholar, CNKI, Google Scholar, Baidu Scholar, etc.), Chinese herbal classics and Chinese Pharmacopoeia and so on. The results show that salt processing is helpful to introduce drugs into the kidney channel and enhance the effect of nourishing Yin and falling fire. The pharmacological effect, chemical composition and in vivo behavior of TCM will change after salt processing. In the future, we should strengthen the research on standardizing the dosage of excipients, the quality standard after processing, the relationship between the change of chemical composition after salt processing and the enhancement of pharmacological efficacy, so as to deeply explain the principle of salt processing, and further improve and optimize the salt making process. By combing the influence of the of salt processing of TCM and analyzed the current problems, we hope to provide guidance for the in-depth study of the salt processing mechanism of TCM and the inheritance and innovation of TCM processing technology.
RESUMO
Traditional Chinese medicine considers Lonicerae japonicae flos to have antibacterial detoxification, liver protection, and gallbladder protection. At present, studies have proven that Lonicerae japonicae flos has a good therapeutic effect on liver injury. Therefore, to confirm the clinical applicability of Lonicerae japonicae flos in the treatment of liver injury, we were the first to compare the pharmacokinetics of an oral ethanol extract of Lonicerae japonicae flos in normal rats and carbon tetrachloride-induced liver injury model rats. A method was developed for the simultaneous determination of 3-caffeoylquinic acid, 4-caffeoylquinic acid, 5-caffeoylquinic acid, 3,5-dicaffeoylquinic acid, 4,5-dicaffeoylquinic acid, protocatechuic acid, Sweroside, and Secoxyloganin in rat plasma by ultra-performance liquid chromatography tandem mass spectrometry. The results show that the method is reliable and reproducible and can be used for quantitative determination of biological samples. The pharmacokinetic parameters showed that the area under the concentration-time curve of eight compounds in the model group was significantly increased. The results showed that the total absorption of the active components of Lonicerae japonicae flos in the blood increased, the clearance rate slowed down, and the bioavailability of Lonicerae japonicae flos increased in liver injury diseases.

The aim of this study was to screen out the active ingredients of Yuanhu Zhitong prescription (YZP) before and after vinegar processing to play an anti-alcoholic gastric ulcer role through spectrum-effect relationship. First, the fingerprint of 16 batches of YZP was studied using the ultra-high-performance liquid chromatography-quadrupole mass spectrometry detector analysis (UPLC-QDA) method. Second, gastric lesion was induced by anhydrous ethanol. The degree of gastric mucosa injury was evaluated by hematoxylin and eosin staining, and the contents of malondialdehyde and tumor necrosis factor α and superoxide dismutase were detected using the enzyme-linked immunosorbent assay kit. Sixteen batches of YZP were analyzed using the spectrum-effect relationship method. Finally, absorption, distribution, metabolism, and excretion (ADME) was used to evaluate the bioavailability of potential compounds. The results showed that the UPLC-QDA method could successfully establish the fingerprint of YZP. Hematoxylin and eosin staining and biochemical indicators showed that YZP had obvious anti-alcoholic gastric ulcer action. Coptisine chloride, corydaline, berberine chloride, palmatine, imperatorin, and phellopterin were screened out using the spectrum-effect method, and all of them possessed good bioavailability. The results of this study suggest that YZP plays an anti-ulcer role by exerting antioxidant and anti-inflammatory effects through six main active components.
