The Supplyside West Conference is a very important Herbal Supplement Industry event. It provides important educational and networking opportunities to this $29 billion market. Since the FDA set out required current good manufacturing practices (cGMP) in 2007, the Herbal Supplement producers are working to meet the new requirements before the FDA audits. These regulations are intended to insure the quality, purity and safety of the Herbal Supplement products available today.
The show is held in Las Vegas, Nevada, October 19-23. Pickering Laboratories exhibited at the show. We introduced our instruments, and methods to the industry. Of primary concern are Mycotoxins and Amino Acids, but also pesticides. Our GPC Clean-up and post-column instruments are well-suited to these applications.
In addition to the literature and instruments in the booth, we presented two posters:
“Immunoaffinity Clean-up and Analysis of Aflatoxins and Ochratoxin A in Herbs & Spices using HPLC with Post-column Photochemical Derivatization”
The production of herbal supplements and spices is a fast growing industry. There are numerous reports on the presence of Mycotoxins in commercially available herbs and spices such as chamomile, black and white tea leaves, ginkgo leaves, paprika and cumin. We developed a simple, sensitive and robust HPLC-Post Column Derivatization method for analyzing Aflatoxins B1, B2, G1, G2 and Ochratoxin A in herbs and spices. AflaOTAClean Immunoaffinity columns contain antibodies specific for both classes of Mycotoxins and allow for fast and efficient sample clean-up. We used the AcceClean automated workstation, which processes three samples simultaneously.
“Accelerated Amino Acids using HPLC with Post-Column Derivatization”
We developed an accelerated amino acids analysis method for Physiological and Protein Hydrolysate samples that utilizes temperature and eluant gradients. Protein Hydrolysates can be analyzed in 48min (inject-to-inject). Amino Acid Analysis is an important step in the Quality Control and R&D of dietary supplements, sports drinks, pharmaceuticals and in any type of sample where the amino acid content is of importance. The objective of the study was to reduce the total run time of Amino Acid Analysis by implementing both a column temperature gradient and a linear buffer gradient using HPLC with Post-column derivatization.
