Abstract
A rapid and efficient method for the extraction and isolation of naringin and narirutin from citrus molasses is described. Naringin and narirutin are structurally similar glucosides present in citrus molasses. The common problem in purification of plant extracts is the large number of constituents present that are similar in nature. A flash chromatographic technique has been developed for the separation of the main flavonoid glucosides present in citrus molasses. This method is a rapid, inexpensive technique and provides compounds with high purity that can be used for biological activity studies. The separation and yield of narirutin and naringin obtained by this method is reproducible.
