Metric Options: CountsSelecting 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.

Artifact Description
The extraction conditions of volatile oil from Chinese elder herb by supercritical CO2 were optimized by single factor experiment and response surface methodology. Flow rate of CO2, the pressure, temperature and time of extraction were employed to examine the influences of the yield of volatile oil. The chemical constituents were separated and identified by Gas chromatography-mass spectrometry (GC-MS). The optimal extracting conditions were flow rate of CO2 25 L/h, extraction pressure 30.5 MPa, at 45.0 ℃ for 2.8 h. The extraction rate of volatile oil from Chinese elder herb was 0.86%. 16 kinds of volatile compounds were separated from Chinese elder herb and accounted for 93.87% of the total extractions. The contents of the more compounds were 3-methylpentanoic acid (29.37%), 3-methylbutanoic acid (13.83%), 4-hexene-1-ol (8.27%), and 3-(ethylthio) butanoic acid (6.46%), respectively.
