Long dan Xie gan pill is a traditional complex compound preparation with a long history for treatment of diseases, including hepatocolic hygropyrexia, dizziness, tinnitus, and deafness. Quality of products from different manufacturers may be varied. Since the current standard could not control the quality of products in a comprehensive and effective way, this study aimed at establishing a practical and convenient approach for holistic quality control of the preparation. This study included both qualitative and quantitative works to get information on the overall composition and main components, respectively. As a result, HPLC fingerprint (UV 240 nm) similarities of all fifty samples were in the range of 0.65∼0.99. Results indicated that there was a difference among products from different manufacturers. Additionally, ten characteristic peaks of the fingerprint were tentatively identified by LC-MS. Further chemometrics analysis was utilized to evaluate the products from different manufacturers. At the same time, the HPLC (UV 285 nm) multicomponent quantification result showed that contents of gentiopicrin, baicalin, baicalein, and wogonin were in the range of 0.61–5.40, 1.96–5.33, 0.10–3.40, and 0.046–1.16 mg·g−1, respectively. Data analysis verified the main different component of baicalein from the fingerprint statistical analysis. It is worth mentioning that the qualitative fingerprint and quantitative multicomponent determination were simultaneously accomplished by HPLC-DAD with dual channels. The study provided sound basis for improving quality control standards. This study also provided practical strategy for overall quality control of traditional Chinese medicines.

Background: Scutellariae Radix (Huangqin) is commonly processed into 3 products for different clinical applications. However, a simple analytical method for quality control has rarely been reported to quickly estimate the degree of processing Huangqin or distinguish differently processed products or unqualified Huangqin products. Objective: To study a new strategy for quality control in the processing practice of Huangqin. Methods: Seven kinds of flavonoids that mainly exist in Huangqin were determined by HPLC-DAD. Chromatographic fingerprints were established to study the variation and discipline of the 3 processed products of Huangqin. PCA and OPLS-DA were used to classify differently processed products of Huangqin. Results: The results showed that baicalin and wogonoside were the main components in the crude and the alcohol Huangqin herb while baicalein and wogonin mainly existed in carbonized Huangqin. The results of mathematical statistics revealed that the processing techniques can make the quality of medicinal materials more uniform. Conclusion: This multivariate monitoring strategy is suitable for quality control in the processing of Huangqin.

In this study, a simple, sensitive and reliable fingerprint analysis method by high-performance liquid chromatography coupled with diode array detection (HPLC-DAD) was developed for quality analysis of Bulbus Lilii, which is a famous traditional Chinese medicine and widely used as a restorative food. Then the developed method was subsequently applied to analyse 16 samples collected or purchased from different origins. Twelve common fingerprint peaks, including four definitely identified peaks, were found in total, and were involved for further characterisation and quality evaluation of Bulbus Lilii. The chemical quality of commercial samples collected from different origins varied obviously, indicating that more attention should be paid to the standardisation of the process of harvesting, manufacturing and storage of Bulbus Lilii. This is the first time that a new method has been established to control the quality of Bulbus Lilii through HPLC-DAD.

The Cost

Quality being the competitiveness of the most important for the company's products and also because the quality has been the hope and desire of everyone, especially the consumer. Customers are not going to focus on a product / service only in terms of price but in good quality inherent in the product or service. Viewed from the importance of the quality of products, each company needs to spend quality, cost of quality is the cost refers to the cost incurred to prevent or expenses incurred as a result of producing a quality product. Efforts to improve the quality of the product will not run without the cost of quality control to overcome the problems faced by the company, where quality control can help the company determine the feasibility of the quality of products based on control limits have been set. This study aims to see how the cost of quality control and to analyze the efficiency of the implementation cost of quality control conducted by Aksan Bakery in Manado. Analysis of the data used is descriptive analysis with qualitative approach and using methods of presentation quality cost ratio analysis to assess the efficiency cost of quality. Based on analysis of the cost of quality control conducted by the company it appears that the cost of quality control conducted by the company do not meet the quality standards that have been set at 2.5% of sales, for the cost of quality issued by the company is greater than a predetermined quality standards, namely amounting to 13.89% of sales. This may imply that the cost of quality control has not been carried out efficiently. Keywords : Efficiency , Cost of Quality

The rifle curve, straightness and roughness of the firearm bore wall play a crucial role to the shooting accuracy and distance. Detection on the bore wall is therefore very important on purpose of improving the accuracy of fine processing and ensuring the quality of products. However, the regular detection method is helpless due to the space and size restriction of the bore wall. In order to solve this technical problem, a detection system for the bore wall is discussed, the system structure is briefly introduced, the system principle is analyzed and the application value of popularization is also pointed out in this paper. The detection accuracy has exceeded the current standard at home and abroad and reached the level of nm. The rifle curve, straightness and roughness of the firearm bore wall play a crucial role to the shooting accuracy and distance. Detection on the bore wall is therefore very important on purpose of improving the accuracy of fine processing and ensuring the quality of product. As for the detection of rifle curve, straightness and roughness of the firearm bore wall, the current method is only limit to the endoscopic camera and computer image processing, and the effect on the larger flaw is obvious but can not reach the fine requirement for the detection of the new products.
