基于UPLC及熵权TOPSIS法分析不同趁鲜加工方式对千里香质量的影响
Analysis of the effects of different fresh-processing methods on the quality of Murraya paniculata based on UPLC and entropy weight TOPSIS Method
摘要
Abstract
To systematically analyze and compare the effects of sun-drying,shade-drying and electric blast-drying(at 50,60,and 70℃)on the quality of tender twigs and leaves of Murraya paniculata,and to provide a scientific basis for optimizing their postharvest processing methods at production areas.Morphological characteristics and thin-layer chromatography profiles were observed and compared.Differences in alcohol-soluble extractives,volatile oil content,and the contents of four flavonoid active components—murrangatin,5,7,3',4',5'-pentamethoxyflavone,5-hydroxy-3',4',6,7-tetramethoxyflavone,and demethylnobiletin—were determined and compared.The quality of the medicinal materials was comprehensively evaluated using the entropy weight TOPSIS method.Different drying methods significantly affected the alcohol-soluble extractives content but showed no significant impact on the volatile oil content.Compared with shade-drying,electric blast-drying at 50℃significantly increased the contents of the four flavonoid components in M.paniculata from various production areas,but had no significant impact on volatile oil content.Compared with traditional shade-drying,electric blast-drying at 50℃with constant temperature blast-drying significantly increased the contents of four active ingredients—murrangatin,5,7,3',4',5'-pentamethoxyflavone,5-hydroxy-3',4',6,7-tetramethoxyflavone,and demethylnobiletin—in M.paniculata from various production areas.The comprehensive quality evaluation results indicated that electric blast-drying at 50℃achieved the highest ranking in multiple production regions.Considering drying time,energy consumption,active ingredient content,and appearance,electric blast-drying at 50℃can be recommended as the preferred postharvest processing method for standardized and industrialized production bases of M.paniculata.关键词
