说明
分析说明
1,3-Dimethylamylamine (DMAA) is a stimulant found in various health supplements. Although often labelled as "natural," derived from geranium plants, it is suspected of actually having synthetic origins. If synthetic, then the supplement would fall under FDA regulations. This study showed that natural geranium oil does not contain detectable levels of DMAA. A modified cyclofructan HPLC columns, LARIHC CF6-P, was used for the analysis.
