In this application, we describe a technique for the monitoring of six cannabinoids, including THC and CBD, in hemp seed oil by HPLC with PDA detection. Figure 1 shows the chemical structures for the six cannabinoids. In recent years, scientific knowledge regarding the composition and health benefits of edible hemp products has significantly increased. Hemp seed oil has been promoted as a good source of nutritious omega-6 and omega-3 polyunsaturated acids, and may be a cleaner, more sustainable alternative to fish oil.
Capsaicinoids are the compounds that produce the pungency, aroma and flavor of chili peppers. The two most abundant capsaicinoids in chili peppers are capsaicin (8-methyl-N-vanillyl-trans-6-nonenamide) and dihydrocapsaicin. Combined, these two make up close to 90% of the most pungent varieties of capsaicinoids, with capsaisin making up about 71%. The capsaicin content of peppers is one of the parameters that determine their commercial quality. The amount of capsaicin can vary, depending on the light intensity and temperature at which the plant is grown, the age of the fruit, and the position of the fruit in the plant. Besides their widespread uses in foods, capsaicinoids are increasingly being used as the active component in pharmaceuticals and have been used as an analgesic against arthritis pain and inflammation. They have also been reported to be active against neurogenic inflammation (as in pepper sprays) and have shown protective effects against high cholesterol levels and obesity. Considering the increased use of capsaicinoids in both foods and pharmaceuticals, there is an increasing demand for their accurate quantitation as part of monitoring the quality of chili peppers. In this regard, this application focuses on the extraction, HPLC separation and quantitation of capsaisin and dihydrocapsaicin in two store-bought chili pepper powders.
The misuse of cold remedies can be prevented by appropriate medical indications and accurate label claims. To that end, the U.S. Food and Drug Administration and the pharmaceutical industry have made it a standard procedure to routinely test drug products to ensure the accuracy of the amount of active ingredients. This application note presents a method for the simultaneous analysis of acetaminophen, dextromethorphan and phenylephrine. Method conditions and precision are presented. A cold medicine tablet is analyzed and the type and amount of active ingredient are confirmed.
Organic acids, used as preservatives, acidulants or stabilizers in food, contribute to the sensory properties of foods and beverages by providing both taste and aroma. Monitoring the content of organic acids in foods is an important step in the food manufacturing process, as well as quality and regulatory protocols, to ensure the purity and composition of finished products. In this application note, a simple and robust HPLC method for the analysis of organic acids in store-bought fruit juices is presented.
With an emphasis on decreasing calorie intake, more and more individuals are focusing on lowering their sugar consumption from foods and beverages. In response to this, food/beverage manufacturers are now introducing the highly touted sugar substitute rebaudioside A (Reb A), in place of all or most of the sugar in certain foods and beverages.,
This application describes an analytical method for the chromatographic separation and quantitative monitoring of seven primary cannabinoids, including THC and THC-A, in cannabis extracts by HPLC with PDA detection. Naturally occurring cannabinoids, the main biologically active component of the cannabis plant, form a complex group of closely related compounds, of which 113 are known and 70 are well described. Of these, the primary focus has been on Δ-tetrahydrocannabinol (THC), as the primary active ingredient due to its pharmacological and toxicological characteristics, upon which strict legal limits have been enforced.
This application describes the sample preparation and analytical method for the chromatographic separation and quantitative monitoring of twelve primary cannabinoids in the extracts of several food matrices by HPLC, using photodiode array (PDA) detection. The method provides exceptional chromatographic repeatability and affords LOQs well below the current concentration levels of interest for cannabinoids in edibles. Thereupon, the method/procedure defined herein can be expected to fulfill the essential task of ensuring product uniformity and cannabinoid screening in edible foods.
Polycyclic aromatic hydrocarbons (PAHs) are prevalent in a number of environmental matrices, and are created as a result of the combustion of fossil fuels. PAHs are water soluble and toxic to invertebrate aquatic organisms. They have also been shown to bioaccumulate in the environment, and their solubility results in binding with soils, sediments and particulate matter. Many government agencies, such as the US EPA, have established regulatory limits for PAHs in environmental matrices. In this application, utilizing a spiking experiment, the levels at which PAHs in surface water can be monitored by UHPLC, with a sub-2 µm particle sized column combined with photo diode array (PDA) and fluorescence (FL) detection, are investigated.
The food industry routinely fortifies many foods with vitamins to enhance their nutritional value and to help with deficiencies in dietary requirements. However, to meet legal requirements, the manufacturers must label their products in accordance to the specific regulations pertaining to the country in which the products are sold and consumed. In 2009, the United States Pharmacopeial Convention introduced the USP Dietary Supplements Compendium (DSC) – an industry directed resource, including regulatory guidance and reference tools. In the U.S., the Food and Drug Administration (FDA) regulates all dietary supplement products and manufacturing practices under 21 CFR (Code of Federal Regulation), Part 111. In Europe, the main EU legislation for vitamins and minerals in food supplements is Directive 2002/46/EC. Considering the above, this application focused on providing a robust chromatographic method for the separation of eight water-soluble B vitamins in vitamin supplement tablets using HPLC with photodiode array (PDA) detection.
This work pursued an effective, efficient and robust HPLC method for the quantitative analysis of lactic and acetic acid in beers by HPLC with PDA detection.
Lactose, also referred to as milk sugar, is the primary carbohydrate present in dairy products. Globally, the analysis of lactose is especially important due to the many individuals suffering from lactose intolerance. The work presented herein provides a method for the routine sample preparation and quantitative determination of lactose in mozzarella and ricotta cheeses and milk. As the monosaccharaides glucose and galactose can be hydrolytically or enzymatically produced from lactose, these two sugars were also chromatographically separated, though not quantitated. The method uses an Altus™ HPLC system with refractive index (RI) detector, which is especially effective for analyzing analytes with little or no UV absorption, such as many dietary sugars.
This application brief provides a routine and reproducible method for the HPLC analysis of 11 organic acids commonly found in juices and other beverages, focusing especially on the relatively higher molecular weight acids.
BPA or bisphenol A is well known for its effect on human health and is a concern in two common polymers - PVC and Polycarbonate. BPA is used in PVC production as a polymerization inhibitor, however residual BPA monomers may remain after polymerization is complete. The concerns over BPA began with baby bottles and spread to include other consumer products like toys and medical devices. Analysis during plastics development and production can mitigate health concerns. The PerkinElmer Flexar™ FX-10 UHPLC system provides a sensitive and robust platform for this analysis. Demonstrated in this application note is the UHPLC analysis of BPA in 3 children’s toy matrices, with a chromatographic run time of less than 10 minutes. Further, two separate extraction techniques are detailed which simulate potential BPA exposure routes children may encounter. For some applications, companies have replaced polycarbonates with new copolymers, such as co-polyester, to eliminate BPA altogether.
