PHYTOCHEMICAL CHARACTERIZATION AND ANTIMICROBIAL ACTIVITY OF SHAMPOO GINGER (ZINGIBER ZERUMBET) FROM TAMIL NADU, INDIAP.A. MARY HELEN, A.M. NIZZY AND T.R. JEGATHEESH
Volatile oil from the rhizomes of Zin giber zerumbet was isolated and characterized by GC-MS. Eleven compounds were identified and the major compounds Zerumbone (25.37%), 13-pinene (23.75%), Thujyl alcohol (15.7%) and Camphor (14.5%) are as the major constituents and this oil contains the minor constituents like 7-Oxabicyclo heptane (7.66%), 1,5,9-Decatriene (7.17%) and Linalyl acetate (3.65%) were identified. The antimicrobial activity of oil extract was tested against human and plant pathogenic bacteria and fungi. The oil showed significant inhibitory activity against the bacteria, Staphylococcus aureus (1.2cm), Lactococcus lactis (0.8 cm), and the fungus Aspergillus awomori (1.5cm), Fusarium oxysporum (1.0 cm), Aspergillus aecularatus (0.9 cm), Candida albi cans (0.8cm), Tricoderma viridae(0.8cm), Rhodotorula sps (0.8 cm) and Aspergillus niger (0.6cm). No inhibitibry activity was observed against the bacteria, Bacillus cereus and E. coll.
