Description:
The essential oils obtained by hydrodistillation of the unripe and ripe fruits ofAlpinia muticaRoxb. andAlpinia latilabrisRidl. were analysed by capillary GC and GC-MS. The oils were principally monoterpenic in nature. The unripe and ripe fruit oils ofA. muticawere characterized by camphor (21.0% and 15.8%), camphene (16.6% and 10.2%),β-pinene (8.6% and 13.5%), andtrans,trans-farnesol (8.0% and 11.2%), respectively. The oils of the unripe and ripe fruits were moderately active againstStaphylococcus aureus, Bacillus subtilis, Trichophyton mentagrophytes,andTrichophyton rubrum. 1,8-Cineole (34.2% and 35.9%) andβ-pinene (20.2% and 19.0%) were the two most abundant components in the unripe and ripe fruit oils ofA. latilabris. The oil of the unripe fruits elicits moderate activity againstStaphylococcus aureusandTrichophyton mentagrophyteswhileCandida glabratawas moderately sensitive to the oil of the ripe fruits.
