Preliminary results have been achieved in the prevention and treatment of cardiovascular disease (CVD) in China, but the number of CVD patients will continue to grow rapidly in the next 10 years. Generally speaking, the prevalence and mortality of CVD in China are still on the rise. CVD has worsened and become a major public health problem. It is urgent to prevent CVD. Therefore, the development of safe, effective and inexpensive drugs for the prevention and treatment of CVD is a livelihood project of great significance. Allii Sativi Bulbus, as a commonly used medicinal and edible herbal medicine, has rich resources and a long history of application. Since the 1980s, many studies on Allii Sativi Bulbus have been carried out by global scholars. The results show that Allii Sativi Bulbus has the effects in reducing blood lipid, preventing atherosclerosis, lowering blood pressure, resisting myocardial ischemia and treating other cardiovascular diseases, with many pharmacological activities such as anti-tumor, anti-bacterial, anti-inflammatory, insecticidal, regulating immunity, anti-oxidation, free radical scavenging activities. Focusing on the regulation of blood lipid metabolism by Allii Sativi Bulbus, the latest literatures at home and abroad have been consulted. Both basic research and clinical trials have shown that Allii Sativi Bulbus has a good hypolipidemic effect. Its mechanism is mainly related to the inhibition of key enzymes in the process of lipid synthesis and related factors regulating lipid metabolism. In this paper, the hypolipidemic effect and molecular mechanism of garlic were reviewed to define its research trends and problems, and provide reference for further research and clinical application of Allii Sativi Bulbus.

Objective: To study the chemical constituents from the aerial part of Allium sativum. Method: The aerial part of A. sativum was treated by heating reflux extraction with 70% ethanol. The combined extracting solution was treated with decompressed recovery solvent to obtain the total extract. The total extract's thick paste was suspended with an appropriate amount of distilled water, and then extracted with petroleum ether, ethyl acetate and water-saturated n-butyl alcohol to obtain petroleum ether extraction fraction, ethyl acetate extraction fraction and n-butyl alcohol extraction fraction. The n-butyl alcohol extraction fraction was isolated and purified by positive phase silica gel column chromatography, ODS column chromatography and preparative HPLC,etc. The structures of the chemical constituents were elucidated by means of physicochemical properties and spectroscopic analysis, and spectral data, like ¹H-NMR, ¹³ C-NMR, DEPT, HMBC and HR-ESI-MS. Result: Seven compounds were isolated and identified as 2-methoxy-phenol-1-O-α-L-arabinopyranosyl-(1→6)-β-D-glucopyranoside(1),phenyl-ethanol-4-O-β-D-xylopyranosyl-(1→6)-β-D-glucopyranoside(2),trans-resveratrol 3-O-β-D-glucopyranoside(3),stigmasterol(4),β-sitosterol(5),stigmasterol-3-O-β-D-glucopyranoside(6) and daucosterol(7). Conclusion: Compound 1 is a new phenolic glycoside named dasuanxinoside J,and compounds 2-7 are isolated from A. sativum for the first time.

Objective:To study the antibacterial activity and chemical constituents of Sojae Semen Praeparatum as a traditional Chinese medicine. Method:Sojae Semen Praeparatum was extracted with 80% ethanol,and the extracts were suspended in an appropriate amount of distilled water and extracted with petroleum ether,ethyl acetate and water saturated n-butanol in turn. The antibacterial activity in vitro was used for screening the active fractions. Using activity-guided-isolation,the active fractions were isolated and purified by silica gel column chromatography and preparative HPLC and other methods. Their structures were identified by physicochemical properties and spectroscopic analysis, such as ¹H-NMR,¹³C-NMR and MS. Result:The ethyl acetate fraction of 80% ethanol extract from Sojae Semen Praeparatum showed a stronger activity and was studied further. Eighteen compounds were isolated, and eleven compounds were identified as daidzein (1),daidzin (2),genistein (3),genistin (4),glycitein (5),glycitin (6),daucosterol (7),thymine (8),adenine (9),uracil (10),uridine (11). Conclusion:The ethyl acetate fraction of 80% ethanol extract from Sojae Semen Praeparatum shows an antibacterial activity. Compounds 1-6 are isoflavones. Compounds 7-11 are isolated from Sojae Semen Praeparatum for the first time.

Atherosclerosis (AS) is a chronic inflammatory disease associated with high morbidity and mortality. The incidence of AS is increasing in the last decades. So development of safe and effective therapeutics for treating AS has become prominently important. Although there are numerous chemical drugs available for treating AS, some drugs are not effective and some have serious side effects. Traditional Chinese medicine (TCM) has a long history for the prevention and treatment of AS due to its less side effects and superior efficacy. This paper describes the effectiveness and underlying mechanisms for prevention and treatment of AS by TCM or its active components. Some TCM, e.g. XuemaiNing, Tongxinluo and Salvia miltiorrhiza have been reported to have cardio-protective effect. Some active components of TCM, e.g. saikosaponin-A, kuwanon G, luteolin and β-elemene have been isolated from various TCM and demonstrated to have beneficial effects on prevention and treatment of AS.

There is no doubt that the traditional Chinese medicine(TCM) is effective, practical and scientific after it was used for thousands of years. However, the mechanisms of action of many TCM are still unclear because of their multi-component, multi-target and multi-level features, which hinder the modernization and internationalization of the TCM. Proteomics is to analyze the composition and activity of intracellular proteins which are changing dynamically from a holistic perspective. It is consistent with the holistic and dynamic views of the TCM and brings about the hope of clarifying the mechanism of action of the TCM. In recent years, great progress has been made in the application of proteomics to determine the mechanism of the TCM. This article introduced the core technologies of proteomics and systematically summarized the applications of proteomics in the study of the mechanism of the Chinese medicinal formulae, single Chinese medicine and monomeric compounds from the TCM to provide innovative ideas and methods for reference.

The genus Ephedra of the Ephedraceae family contains more than 60 species of nonflowering seed plants distributed throughout Asia, America, Europe, and North Africa. These Ephedra species have medicinal, ecological, and economic value. This review aims to summarize the chemical constituents and pharmacological activities of the Ephedra species to unveil opportunities for future research. Comprehensive information on the Ephedra species was collected by electronic search (e.g., GoogleScholar, Pubmed, SciFinder, and Web of Science) and phytochemical books. The chemical compounds isolated from the Ephedra species include alkaloids, flavonoids, tannins, polysaccharides, and others. The in vitro and in vivo pharmacological studies on the crude extracts, fractions and few isolated compounds of Ephedra species showed anti-inflammatory, anticancer, antibacterial, antioxidant, hepatoprotective, anti-obesity, antiviral, and diuretic activities. After chemical and pharmacological profiling, current research is focused on the antibacterial and antifungal effects of the phenolic acid compounds, the immunosuppressive activity of the polysaccharides, and the antitumor activity of flavonoids.
