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.

Lecture / Presentation Description
Kratom or Mitragyna speciosa, is a plant that has traditionally been used as an ethnopharmacological aid in Southeast Asian cultures to relieve stress, fatigue, and pain. Kratom has gained popularity in the West for its dose-dependent effects, serving as a stimulant in low doses, or as an opioid with sedative effect in high doses. Extensive kratom use has been shown to induce a variety of negative side effects that include nausea, liver damage, and seizures. Kratom has been banned in several countries, however, in the United States kratom products are commercially available, they are not regulated, and quality control evaluation is not required. In the current study, we sought to evaluate the variation in alkaloid content across kratom products. We hypothesized that bioactive alkaloid content in commercially available products may vary significantly due to inadequate quality control. To test this hypothesis, we have developed a standardized method to quantitate five of the most abundant alkaloids in kratom via high-performance liquid chromatography and triple quadrupole mass spectrometry. Expected dosages of mitragynine and 7-hydroxymitragynine were found to be inaccurate from the product label, and significant variation of the other six alkaloids were seen between products. The amount of mitragynine in the powder and capsules varied from 4.05 mg/g to 6.80 mg/g across products, most product labels indicate the average dose of mitragynine to be 13.6-15.0mg/g. The use of this analytical method to measure alkaloid content in kratom products can inform consumers of the amount of bioactive components they are consuming so that inadvertent overdose and death may be prevented.
