Natural products contain many kinds of substances, such as proteins, polypeptides, amino acids, resins, colloids, lignin, fats, oils, waxes, alkaloids, glycosides, organic acids, phenols, quinones, lactones, steroidal tannic acids, antibiotics and other natural chemical components. Due to the unique physical and chemical properties, natural products are used in many fields, including food, cosmetics and fragrances, medicine and others.
Natural products CRMs are often used in chromatographic detection for qualitative or quantitative analysis of natural ingredients to ensure the safety of products. Natural products CRMs are physical standards, which has one or more eigenvalues. In addition, natural products CRMs must be accompanied by a certificate and they are needed to be traceable. Moreover, according the demands of detection, natural products CRMs can be a pure substance or a mixed material. Commonly used natural products CRMs include eugenol, citric acid, salicylic acid, resveratrol, coumarin and others.
Medical field: Many natural products have medicinal value and can be used as medicines. Using natural products CRMs, qualitative or quantitative analysis of some components in natural substances can be analyzed, which can be used to judge the quality and safety of the natural products medicines. For example, clove is a natural medicinal substance, and its quality is often related to the content of eugenol. It has been reported that the standard curve can be drawn using eugenol CRMs. Based on the standard curve, the content of eugenol in cloves can be accurately determined by gas chromatography.
Food field: Natural products are found in many kinds foods and they are important sources of flavor and efficacy. Therefore, it can be helpful to monitor the food quality by the virtue of natural products CRMs. For example, resveratrol is a natural product found in wine, which can be used to fight cancer and decrease blood fats. It has been reported that the quantitative determination of resveratrol has been achieved by high performance liquid chromatography using natural products CRMs. In addition, this method has the advantages of high sensitivity and good selectivity.
Cosmetics field: Natural products are one of the commonly used added ingredients in the field of cosmetics. In order to ensure the safety and efficacy of cosmetics, it is necessary to carry out quantitative or qualitative analysis of natural ingredients in cosmetics. Chromatography is the most commonly used analysis method and natural products CRMs are essential during the detection process. For example, coumarin can be accurately detected by gas chromatography-mass spectrometry based on coumarin CRMs. Moreover, this method has the advantages of simplicity and high efficiency.
Others: In addition to the above fields, natural products CRMs can be used in chromatography methods to achieve animal feed quality control, aroma quality identification and others.
