Genetics and Molecular Research, 2011
Mutagenic and antimutagenic activities of the medicinal plant Duguetia furfuracea were assessed using SMART/wing and ring-X-loss tests. For the ring-X-loss test, 2- to 3-day-old Drosophila melanogaster ring-X-lineage males and virgin ywsn³ females received D. furfuracea infusion at doses of 0.085, 0.042, or 0.014 g/mL for 24 h.
