Aryl-LA enantiomers were analyzed as described in the Materials and Methods section. The percentage of the earlier eluting peak (area under the curve), herein designated as “1st peak”, was calculated using the following formula: The area under the curve of the 1st peak/total area under curve × 100. Results are expressed as the mean ± SD.
