Biological Activities
Compounds
Conditions
Dioscorea composita possesses internal mechanisms that effectively treat drought and various drought stresses. Through the regulation of specific transcription factors like DcWRKY5, the plant enhances its ability to treat drought and salt. Furthermore, the plant demonstrates a capacity to treat salinity and salt through increased antioxidant enzyme activity and proline accumulation. These physiological responses also allow Dioscorea composita to treat osmotic stress caused by environmental factors like polyethylene glycol. Consequently, the plant's genetic regulation provides a robust defense against these critical environmental limitations.
Preparations
Dioscorea composita is prepared as an essential oil that can be isolated from the plant's otherwise non-useful herbage. This extraction process utilizes the multicellular oil glands found on the epidermal layers of the leaves. Through gas chromatographic-mass spectroscopy analysis, the oil was found to contain 37 distinct compounds. Elemol serves as a major constituent within this specific essential oil, accounting for 22% of its total composition. This discovery establishes the plant as a novel bioresource for essential oil production alongside its traditional uses.
Parts used
Dioscorea composita is a significant plant species that offers more than just the well-known medicinal value of its tubers. Recent research highlights that the leaves of this plant serve as a valuable source of essential oils. Through microscopic analysis, scientists have identified the presence of multicellular oil glands located on the epidermal layers of the leaves. These leaves contain a complex mixture of compounds, with elemol identified as a major constituent of the extracted oil. Consequently, the herbage of Dioscorea composita represents a promising new bioresource for essential oil production.
