Abstract
To further improve the quality standard of honeysuckle (Lonicera japonica Thunb.) tea, we investigated and analyzed the quality-related characteristics of the 25 brands of commercial honeysuckle tea in this study. Following the general label rules of prepackaged food, this study assessed the label compliance of different brands of honeysuckle tea. Furthermore, we conducted an investigation and assigned grades to the characters of honeysuckle tea in accordance with the agricultural industry standard. The pH value of the sample was measured using a pH meter. The total flavonoid content was determined through ultraviolet spectrophotometry. The content of chlorogenic acid was determined using HPLC. The correlation and distribution characteristics of the data were analyzed by means of SPSS, Microsoft Excel and other statistical tools. Based on a survey of 25 commercially available honeysuckle samples, a total of 361 test results were obtained. This dataset is expected to offer valuable references for the development of national standards for honeysuckle substitute tea.
