Laboratory Testing Case Studies

Challenge: The objective of this project at Diteba was to develop methods for complete compositional analysis of Krill Oil. Such characterization included total lipid / fat content, phospholipids, free fatty acids, triglycerides, cholesterol esters, phosphatidylcholine, phosphatidylserine, phosphatidylethanolamine, phosphatidylinositol, sphingomyelin, lysophosphatidylcholine, sterols, cholesterol, sigmasterol, sigmastanol, sitosterol, vitamin D-3, vitamin E, and carotenoids: canthaxanthin, astaxanthin.

Challenge: The goal of this project was to develop efficient analytical methods for complete compositional analysis of lipid-based drug candidates.  Analytical method requirements included extraction, separation, identification and quantification.  Such work would support development of formulations which would include a small amount of a well accepted non-medicinal ingredient commonly used in food and drug products.  This undertaking focused on the development of a full fatty acid profile analysis of new lipid-based drug candidates targeted to formulate advanced products related to High Density Lipoprotein (HDL), often called "good cholesterol".

Challenge: Diteba undertook research with the technological objective to develop a suitable procedure that was capable of detecting and quantifying all nine main components in an energy soft drink: caffeine, niacin, vitamin B₆, pantothenic acid, riboflavin, vitamin B₁₂, taurine, glucuronolactone and inositol. The procedure was intended for use in quality control testing and long-term stability testing of energy drinks.

Challenge: The objective of this project was to develop simple, precise, rapid and reproducible analytical methods for the quantification of: a) major Ginsenosides in Panax quinquefolius extract; and b) Flavonols in Ginkgo Biloba extract and use these methods as quality control tools for commercial energy drink products.
