Abstract
Abstract: The nutrient content and the medicinal values of the traditional medicine Knoxia corymbosa wild (Rubiaceae family) has not been assessed so far. It is known for gastro- intestinal and skin treatments. The assessment of fatty acids and flavonoids, prominent secondary metabolite with nutraceutical and pharmaceutical potential, present in the species is done using solvent extraction and chromatographic techniques (GC-FID/MS, LC-MS/UV). Three major flavonoids, quercetin, myricetin and kaempferol which has high nutraceutical potential are observed. Palmitic acid, Palmitoleic acid, Stearic acid, Myristic acid, Oleic acid, Linoleic acid (ω-6) and Alpha-Linolenic acid (ω-3) are identified using internal standards. The mass spectral data gives the presence of gamma-linolenic acid and arachidonic acid and very long saturated fatty acids also. The ratio of ω-6/ ω-3 is found to be approximately 1. These results indicates that the species K. corymbosa is a potential source of flavonoids and fatty acids which results in high nutraceutical effects.
