Three new phenolic compounds from a manipulated plant cell culture, Mirabilis jalapa.
Bioassay-guided fractionation of an organic extract of the cell mass from a manipulated plant cell culture of Mirabilis jalapa led to the isolation and subsequent identification of three new phenolic compounds, 1, 2, and 3. The isoflavone 1 and dehydrorotenoid 2 were identified as the principal antifungal principles from this plant cell culture with IC(50)'s of 25 and 48 microg/mL, respectively, against the test organism, Candida albicans DSY1024. The rotenoid 3 was inactive at 200 microg/mL in this assay.
