Abstract
Introduction: Farfarae Flos is widely used as a traditional herbal medicine. Currently, its size has been the primary grading criterion used in market circulation. Whether this empirical criterion can accurately reflect the quality of the medicinal material has not been systematically studied.
Objective: This study aimed to evaluate the quality of Farfarae Flos from different regions based on their grades.
Methods: Ultra-high performance liquid chromatography coupled with electrospray ionization quadrupole time-of-flight mass spectrometry (UPLC-ESI-Q/TOF-MS/MS) were applied to study the chemical constituents of Farfarae Flos; high performance liquid chromatography (HPLC) was used to quantify the content of Farfarae Flos samples. Meanwhile, fingerprint analysis and chemometric methods, including principal component analysis (PCA) and analysis of variance (ANOVA), were used to evaluate the quality differences among 33 batches of Farfarae Flos samples of different grades.
Results: A total of 95 individual components were identified in Farfarae Flos. Fingerprint analysis revealed 23 common peaks, with fingerprint similarity among the 33 batches ranging from 0.838 to 0.995. PCA divided the 33 batches of Farfarae Flos into three categories based on their grades. ANOVA indicated significant differences in five of the 14 main active components across different grades of Farfarae Flos, with two components showing extremely significant differences. HPLC content determination showed that the content of 11 main active components was positively correlated with the grades of Farfarae Flos.
Conclusion: This method is straightforward, efficient, and reliable, offering a valuable reference for establishing quality grading standards and ensuring the quality control of Farfarae Flos.
期刊介绍：
Phytochemical Analysis is devoted to the publication of original articles concerning the development, improvement, validation and/or extension of application of analytical methodology in the plant sciences. The spectrum of coverage is broad, encompassing methods and techniques relevant to the detection (including bio-screening), extraction, separation, purification, identification and quantification of compounds in plant biochemistry, plant cellular and molecular biology, plant biotechnology, the food sciences, agriculture and horticulture. The Journal publishes papers describing significant novelty in the analysis of whole plants (including algae), plant cells, tissues and organs, plant-derived extracts and plant products (including those which have been partially or completely refined for use in the food, agrochemical, pharmaceutical and related industries). All forms of physical, chemical, biochemical, spectroscopic, radiometric, electrometric, chromatographic, metabolomic and chemometric investigations of plant products (monomeric species as well as polymeric molecules such as nucleic acids, proteins, lipids and carbohydrates) are included within the remit of the Journal. Papers dealing with novel methods relating to areas such as data handling/ data mining in plant sciences will also be welcomed.
