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 rat...

Geranium robertianum L. (Geraniaceae), is known as Herb Robert, Red Robin and Storksbill. This plant is native to Europe, Asia, North America and North Africa. G. robertianum is an annual or biennial plant, with the strong scent. In traditional herbalism Herb Robert was used for the treatment of wounds, ulcers and diarrhea and as a remedy for toothache and nosebleeds (1, 2). The active compound...

Eighty-eight percent of arteries in patients with amaurosis fugax or hemispheric transient ischemic attacks had angiographically demonstrable lesions at the carotid bifurcation. Eighty-one percent had stenoses or occlusions at the carotid bifurcation; 7 percent had ulcerative lesions without stenoses at this site. Forty-nine percent of arteries in these patients demonstrated ulcerative lesions ...

Geranium oil is known as a floral substitute of rose essential with its pungent rose-like odor and one the most valuable oils. Favorable quality properties make geranium exigible for food industry applications. This study determined chemical fingerprint using robust vibrational spectroscopy techniques (Fourier transform infrared Raman spectroscopy). The mid-infrared characterization was accompl...

Geranium L. is a genus of over 350 species distributed throughout most of the world, except in lowland tropical areas. It is the largest genus of the Geraniaceae and is represented in the New World by 137 species. This dataset includes 8,937 records that covers the genus Geranium the New World, providing an updated, taxonomically consistent and a sound geographical distribution of the 137 speci...

Four thymol derivatives, 2,5-dimethoxythymol (1), 2-methoxythymol isobutyrate (2), 10-isobutyloxy-8,9-epoxythymolisobutyrate (3) and 10-(2-methylbutyloxy)-8,9-epoxythymolisobutyrate (4) were isolated from the aerial parts of Carpesium divaricatum. The structures were elucidated by high field 1D and 2D NMR techniques.
