Identification
Biological Activities
Compounds
Conditions
Dioscorea collettii var. hypoglauca contains bioactive compounds that effectively target the growth of fungal pathogens. Specifically, the ethanol extract of its rhizomes has been shown to induce morphological deformation in the mycelia of Pyricularia oryzae. Researchers identified two key substances responsible for this effect: a new pregnane glycoside named hypoglaucin G and a known glycoside. These compounds achieved morphological deformation at minimum concentration values of 135 microM and 236 microM, respectively. This interaction highlights the potential of the plant's chemical constituents to disrupt the structural integrity of this specific fungus.
