Conditions
Exacum affine demonstrates significant anti-influenza virus type A activity when tested through methanol extracts. In studies involving medicinal plants from the island of Soqotra, this species was identified as one of several plants capable of inhibiting the virus. The methanol extracts of the plant achieved a 50% inhibition (IC50) at concentrations ranging from 0.7 to 12.5 microg/mL. This specific antiviral effect was evaluated using in vitro influenza virus type A/MDCK cell systems. Consequently, the plant serves as a notable subject in the search for natural compounds that combat influenza.
Preparations
Exacum affine is prepared as methanol extracts to investigate its medicinal properties. These specific extracts were utilized during a study focusing on the phytochemical screening of endemic plants from the island of Soqotra. Through this preparation, the plant's potential antiviral activities were tested against various viral systems. Specifically, the methanol extracts of this species demonstrated inhibitory effects against the influenza virus type A. This process allowed researchers to determine the concentration required to achieve a 50% inhibition level.
