COMPARISION OF PHYTOCHEMICALS IN THE FLOWER BUDS, PEDICELS AND LEAVES OF SYZYGIUM AROMATICUM (L.) MERRIL AND PERRY

Abstract

Objective: To analyse and compare the major chemical components in the flower buds, pedicels and leaves of Syzygium aromaticum by Gas-Chromatography Mass spectrometry technique. Methods: Healthy and mature flower buds, pedicels and leaves were shade dried and pulverized using a mechanical grinder. The powder was successively extracted with ethanol (40-60o C). The extracts were concentrated under reduced pressure in a rotary evaporator. The ethanolic extracts of the plant parts such as leaves, pedicels, and buds were used for GC-MS analysis.Results: The major constituent is eugenol. Pedicels contain 79.75% eugenol, buds contain 74.12% eugenol and leaves contain 51.03% eugenol. In addition to eugenol, other important components are Acetyl eugenol, Caryophyllene, Humulene and Caryophyllene oxide.Conclusion: Eugenol has a wide range of medicinal properties such as antiseptic, anaesthetic, analgesic anti-inflammatory. Commercially pedicel is not used for eugenol extraction. Present study has revealed that it could be used as a promising one in pharmaceutical industry in addition to flower buds.
