Multi-Residue Pesticide Analysis in Herbal Juices using GC-MS/MS

Instrument Type: GCMSMS

The Thermo Scientific™ TSQ™ 8000 Evo triple quadrupole GC-MS is an excellent tool for the control of MRL levels in food commodities. The enhanced velocity optics (EVO) driving EvoCell collision cell technology provide high SRM transition speeds, precision, and sensitivity for even complex methods involving several pesticides in a short run time. This application is focused on the analysis of 247 compounds in two different herbal juices, Aloe vera and Amla (Indian gooseberry), demonstrating the potential of the method to detect trace level compounds at concentrations as low as 1-2 ng/g.

AN335: Accelerated Solvent Extraction (ASE) of Active Ingredients from Natural Products

Instrument Type: HPLC

Herbal products, nutraceuticals, and other food supplements are subject to increasingly rigorous investigation and development. Industry standardization, as well as labeling requirements under new federal regulations, have prompted tighter regulation and monitoring of the active ingredients in these products . This Application Note describes the use of ASE for extraction of commercially available nutritional supplements, specifically hypericin from Hypericum perforatum (St. John's wort) and berberine from Hydrastis canadenis (goldenseal root).

Rapid Screening of Dietary Supplements with Direct Analysis ID-CUBE Coupled to an Exactive Mass Spectrometer

Instrument Type: LCMS

In Westernized cultures, dietary supplements have been gaining popularity in recent years. In China, traditional herbal supplements have been used for millennia. In both cases, the threat of adulteration and need for further characterization of ingredients have been driving forces behind the need for increased screening. This note presents a new approach to the rapid screening of a product marketed as an herbal weight loss aid and the fingerprint characterization of omega fatty acid dietary supplements derived from marine and flaxseed oils.
