Pungent and bitter, cytotoxic and antiviral terpenoids from some bryophytes and inedible fungi.

Most liverworts elaborate characteristic odiferous, pungent and bitter tasting compounds many of which show antimicrobial, antifungal, antiviral, allergenic contact dermatitis, cytotoxic, insecticidal, anti-HIV, superoxide anion radical release, plant growth regulatory, neurotrophic, NO production inhibitory, muscle relaxant, antiobesity, piscicidal and nematocidal activities. Several inedible mushrooms produce female spider pheromones, strong antioxidant, and cytotoxic compounds. The present paper is concerned with the extraction and isolation of terpenoids from some bryophytes and inedible fungi and their pungent and bitter taste, and cytotoxic and antiviral activity.
