ABSTRACT
Health food containing Chinese materia medica has many advantages in health preservation and reducing the risk of disease occurrence,which meets people's demands for " great health" and " preventive treatment of disease". However,due to its complex ingredients,diverse quality of raw materials,as well as the vagueness and lack of integrity for existing quality standards,chaos is caused in the health food market,which restricts its healthy development and also poses new challenges to the quality control of healthy food. At present,the total component content or single component content is determined in most functional/marker component examinations. Safety and microbial detection methods fail to cover the contamination range of the raw materials of Chinese materia medica.Therefore,it is impossible to meet the purpose of ensuring authenticity,safety and efficacy. In recent years,a lot of Chinese materia medica extracts have been used as raw materials for food products,but many extracts lack standards. The author believes that the quality control of health food containing Chinese materia medicas should start with the quality control of Chinese materia medica extracts. In this way,product quality is controlled from source to ensure product consistency; secondly,the overall quality control should be strengthened to ensure the authenticity of the products; the scope of safety inspection shall be expanded to fundamentally ensure the safety of products. At the same time,we should strengthen the quality control of whole process and strengthen the overall quality control of raw materials to produce health food of high quality.

In recent years, researches on the antibacterial experiments of single herb, extracts, monomer ingredients and the compound preparations have confirmed that a variety of Chinese meteria medica have good antibacterial effects, and they are not easily produced drug resistance. Ampelopsis grossedentata, which can be used as medicine and food, contains various biological ingredients. Among them, flavonoids have desired antibacterial effect and synergistic effect when combined with antibiotics. In this review, antibacterial effects of A. grossedentata were summarized from domestic and foreign study literatures in the recent decade, including the main antibacterial components, the antimicrobial effects, and mechanism of this medicinal plant, aming to provide reference for the studies on the physiological and pharmacological functions, clinical application, and product development of A. grossedentata.
ABSTRACT
Objective:To confi rm acidic extracts of Chinese materia medica having an inhibition to melanin synthesis. Methods: By L-DOPA oxidation method, the in vitro determination was studied to get tyrosinase activity’s inhibition of acidic extracts from 28 kinds of Chinese materia medica with high, middle and low concentration solution. Results: First, Acidic extracts from 28 kinds of Chinese materia medica at high concentration (25g/L) showed potent inhibitory action on tyrosinase activity. The highest inhibition rate was 96.50%, which was from the acidic extract of Fructus Mume. The next was fructus schizandrae with 85.33% inhibition rate. Compared with a 56.67% inhibition rate of 2 mmol/ml control sample arbutin, both Fructus Mume and fructus schizandrae had a large signifi cant deviation ( P
