Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Recent studies on Opisthopappus taihangensis have focused on its health-promoting properties, but detailed research on how different drying processes affect its metabolites and bioactivities is scarce. This study compared indoor shade drying, heat drying and freeze drying on the chemical profile and health-related activities of O. taihangensis. UPLC/Q-TOF-MS and various assays (DPPH, ABTS, FRAP) were used to evaluate changes in composition and antioxidant capacity, while antibacterial and enzyme inhibitory effects were also tested. Freeze-drying stood out, maintaining the highest levels of health-beneficial compounds like phenylpropanoids and showing superior antioxidant activities. Notably, significant correlations (P < 0.01) were found between total phenols, flavonoids, and antioxidant properties Freeze-dried O. taihangensis also displayed robust antibacterial activity against Streptococcus hemolyticus-β and the most effective inhibition of pancreatic lipase. The study concluded that the freeze-drying method proved to be the best way for preserving its health benefits, which is essential for its industrial application.
