The essential oils obtained from the leaves, stems, roots and fruits of Alpinia polyantha D. Fang (Zingiberaceae) have been studied. The leaf oil was comprised mainly of camphor (16.1%), α-pinene (15.2%) and β-agarofuran (12.9%), while the major constituents of the stem oil were α-pinene (12.4%),
The essential oils of the leaves, stems, rhizomes and roots of the medicinal plant Alpinia galanga from southern India were investigated by GC-FID, GC-MS and olfactometry. In all four samples, mono- and sesquiterpenes as well as (E)-methyl cinnamate could be identified. They are responsible for the
This study aimed at investigating the anti-inflammatory potential of essential oil from rhizome and leaf of Alpinia calcarata Rosc. (ACEO) with the focus of its topical anti-inflammatory activity along with its dominant compounds 1,8-cineole and α-terpineol using mouse ear edema model.
The essential-oil compositions of leaves, flowers, and rhizomes of Alpinia galanga (L.) Willd., Alpinia calcarata Rosc., Alpinia speciosa K. Schum., and Alpinia allughas Rosc. were examined and compared by capillary GC and GC/MS. Monoterpenoids were the major oil constituents identified.
The essential oils from the leaves, flowers and roots of cultivated Alpinia speciosa K. Schum. were examined by capillary GC and GC-MS. Monoterpenoids composed 89.6% of the total identified constituents of the leaf oil, out of which 59.3% were oxygenated, represented mainly by terpinen-4-ol (28.4%)
