Each beekeeping product has its own chemical composition which varies from producer to producer. Some of these bee products have been used for centuries in traditional medicine, but to date research has demonstrated many other medicinal properties of these products that were not known. Therapeutic properties of bee products have been discovered even against various types of cancer and scientists are continuing their research to discover other secrets behind the therapeutic properties of bee products. In addition, therapeutic effects of bee products have also been discovered against COVID-19 disease which has significantly affected global health. Finally, it is concluded that bee products are proven to be one of the most valuable medicines that nature can offer showing the great value of the science of beekeeping.展开更多

A rapid high-performance liquid chromatographic method for determination of lipoic acid in a nutritional supplement was developed. The method involved sample preparation and the mobile phase comprised of 50 mM disodium hydrogen phosphate buffer (pH 2.5 adjusted with 1 M H<sub>3</sub>PO<sub>4</sub>): acetonitrile in the ratio of 50:50. The separation was done using a C18 column (150 mm) and detection was carried out using UV detection at 201 nm. The assay was found to be linear in the range of 1.56 - 50 μg/mL with the correlation coefficient of 0.9997. Method precision was determined while LOD was 0.05 μg/mL and LOQ 0.15 μg/mL. The chromatographic peak LA retention time was 6 min.展开更多
