The content of berberine hydrochloride (BH) in compound berberine tablets (CBTs) is subject to strict requirements. Its content is usually measured based on chemical analysis. In this paper, the fluorescence spectral imaging method was used to study the relative content of BH from a physics perspective. By comparing the relative fluorescence intensity of self-made CBTs with different mass percentages of BH, a linear positive relationship was observed between the BH content and the relative fluorescence intensity, and accordingly the quality of CBTs of different brands was evaluated. The results indicate that the fluorescence spectral imaging method can be a simple, fast and nondestructive semi-quantitative analysis method to determine the content of BH in CBTs, and this method has great potential in the quality control of CBTs.

This study aims to analyze the effect of product quality and service quality on brand image and customer satisfaction either partially or simultaneously on Giant Citra Raya Tangerang. The population of this study is Giant Citra Raya customers which averages 2,070,823 / 12/30 = 5752 per day. The sample in this research using Slovin formula is 152 customers. Quantitative analysis method using path analysis, followed by determination analysis (R Square), partial hypothesis testing (t test) and simultaneous (F test) with alpha 5 percent. Before further analyzed first tested the instrument and test the classical assumption. Analytical tool using SPSS version 21.0 for windows. The result of the research shows that product quality and service quality are partially and simultaneously have positive and significant effect on brand image and customer satisfaction, and brand image has influence to customer satisfaction at Giant Citra Raya Tangerang.
