Evaluating the Potential of Portulaca oleracea L. for Parkinson’s Disease Treatment Using a Drosophila Model with dUCH-Knockdown

Table 1

The IC₅₀ of dUCH-knockdown larval extract in DPPH assay; flies were treated with the concentrations of 0–15 mg/mL PWE.

Fly lines	IC50	Standard error
dUCH-Kd	0.9404	0.0827
dUCH-Kd + 1.25 mg/mL	0.4226	0.0292
dUCH-Kd + 5 mg/mL	0.2613	0.0269
dUCH-Kd + 15 mg/mL	0.2383	0.0325

Calculated by the dilution rate of larval extract at which the larval extract can convert 50% of DPPH radicals (population size N = 50). dUCH-Kd: dUCH-knockdown flies.
