| Popis: | The essential oil compositions of the rhizomes, flowers, leaves, and pseudostems of Hornstedtia scyphifera (J. Koenig) Steud were studied for the first time. A total of forty three constituents were identified from the rhizome, flower, leaf, and pseudostem oils, representing 90.9%, 82.4%, 79.7%, and 82.6%, respectively. α-Selinene was found dominant in the flower (10.8%) and pseudostem (12.4%) oils, while the rhizome and leaf oils contained germacrene D (15.5%) and camphor (12.6%) as the main constituents, respectively. The rhizome, flower, and leaf oils showed moderate activity against Gram positive bacteria with MIC values of 225 to 450 μg/mL and inhibition zones of 8.4 to 10.0 mm. The leaf oil showed good β-carotene bleaching inhibition activity (64.8%) and a low IC50 value for DPPH radical scavenging activity (650.4 μg/mL). The flower oil showed potential α-glucosidase inhibitory activity with an IC50 value of 21.44 μg/mL. |
