Quality control of Liujiang ultrafine powder
摘要
Abstract
The objective was to establish the quality control standard for the ultrafine powder of Liujiang.Pomegranate peel and dried ginger were mixed in a ratio of 1∶1 to prepare the ultrafine powder.The particle size of Liujiang ultrafine powder was determined using laser particle size analysis;microscopic identification was employed to observe the microscopic characteristics of the powder;thin-layer chromatography(TLC)was used for qualitative identification of dried ginger and pomegranate peel;high-performance liquid chromatography(HPLC)was utilized for the determination of the content of ellagic acid and 6-gingerol.The results showed that the particle size of Liujiang ultrafine powder was less than 48 µm after processing;no significant fibrous structure was observed under the microscope;in TLC,the test samples and reference materials showed spots of the same color at corresponding positions,with no interference from negative samples;in HPLC,the content determination methods for ellagic acid and 6-gingerol showed no interference from negative samples,with a linearity correlation coefficient R2 of at least 0.999,RSD of precision,repeatability,system suitability,and stability and content determination were all less than 2%,and the average recovery rate of ellagic acid and 6-gingerol were all above 95%.After testing 10 batches of samples,it was stipulated that the content of ellagic acid and 6-gingerol in 1 g of Liujiang ultrafine powder should not be less than 1.44 mg and 0.62 mg,respectively.The established method is specific,reproducible,easy to operate,and can be used for the quality control of Liujiang ultrafine powder.关键词
