Abstract:
Eugenia caryophyllata (clove) was extracted by cold extract using deionised water and characterized to determine the phytochemicals and structures of the extract using qualitative study, GC-MS and NMR analysis. The results showed the presence of phytochemicals except Protein- Amino acids which is absent. The phytochemicals evaluated in the aqueous extract of Eugenia caryophyllata (clove) were in the order of total phenolics > flavonoids with the respective values of 6.6 > 2.6 mg/g of extract. Presence of high level of phenolic compounds revealed that Eugenia caryophyllata (clove) extract can have good antioxidant capacity. The resulting spectrum of ¹H NMR analysis found that the existence of distinct peaks signals at 2.36, intensity of 4134.6 and 4011.2 in the range of 2.47 – 2.25 with reference to the proton of acids H-C-OOH, carbonyl compounds HC–C=O, aromatic methyl group Ar–H (Ar–C–H, benzylic ) and Methyl ketone group HC– (R)-C=O. The results demonstrate the characterisation of Eugenia caryophyllata (clove) revealing the phytochemical properties and isolated compounds in relation to its general use as a medicinal plant.
