This application note describes the extraction of benzodiazepine compounds from whole blood, prior to GC/MS analysis. This protocol also allows the simultaneous extraction of various other drugs of abuse classes: amphetamines, barbiturates, cocaine and opiates.
ISOLUTE® SLE+ columns with 1 mL sample capacity are used to extract whole blood samples following a straightforward sample dilution. No protein precipitation or other pre-treatment is required prior to sample loading. The sample preparation procedure delivers clean extracts, good recoveries and RSD values and LLOQs from 10 ng/mL (analyte dependant).

COPYRIGHT © MR- Tribulus Terrestris: Origins Tribulus Terrestris (Tribulus terrestris L.) originated in the two most ancient medicines in the world: Ayurvedic medicine (India) and traditional Chinese medicine. The plant has been used for more than 3,000 years. Its different effects on the body are well-known, and it enjoys a good reputation. Traditionally, it was used to combat diseases of the liver and kidneys, as well as urinary diseases. Today, however, the usage of Tribulus has evolved (especially in Europe, the United States and Canada), and it has come to be most broadly used as an aphrodisiac to stimulate the libido. The plant (especially its fruit) is also commonly used for its anabolic effect by bodybuilders because it promotes the building of muscle mass. Tribulus is considered by herbalists to be an excellent adaptogen (it adapts to the body’s different needs).
