1,3-Dimethylamylamine (DMAA) is a stimulant existing in various pre-workout supplements and often labelled as part of geranium plants. The safety and origin of DMAA in these supplements is the subject of intense debate. In this study, the enantiomeric and diastereomeric ratios of two different known synthetic DMAA compounds, as well as the total concentrations of DMAA and its stereoisomeric ratios in 13 different supplements, were determined by gas chromatography. The stereoisomeric ratios of…

This study indicates DMAA contained in DS is of a synthetic origin and is not present in the plant species Geranium and Pelargonium; thus the 'natural' origin and use of DMAA as an ingredient inDS is not substantiated.

The CE method employing an indirect UV detection for the enantioseparation of 1,3‐dimethylamylamine (DMAA), widely used in various preworkout and dietary supplements labeled as a constituent of geranium extract, was developed and applied for the determination of the stereoisomeric composition ofDMAA in commercial dietary supplements to verify the potential natural origin of DMAA.

- 2012
Oral preparations with >4 mg DMAA per dose unit should be considered as effective as a bronchodilator and food supplements that exceed that limit are in fact subject to the Medicines Act and require licensing.

An unusual class of chiral selectors, cyclofructans, is introduced for the first time as bonded chiral stationary phases, and it appears that partial derivatization on the CF6 molecule disrupts the molecular internal hydrogen bonding, thereby making the core of the molecule more accessible.
