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
Eighteen undescribed xanthones, including six pairs of xanthone enantiomers, three xanthones, and three xanthone glycosides, together with one pair of known xanthone enantiomers and 12 known xanthones, were isolated from the stems of Calophyllum membranaceum Gardn. et Champ. Their structures were elucidated by spectroscopic analysis, and the absolute configuration of the enantiomers was determined by using experimental and calculated electronic circular dichroism data. All compounds were screened for their anti-inflammatory effects on LPS-induced BV-2 microglial cells. Among them, six compounds showed remarkable activities with IC 50 values of 7.8–36.0 μ M.
