Taguchi method with an L8 orthogonal array and analysis of variance (ANOVA) were used to evaluate the effect of pH, amount of Cynara scolymus L.(artichoke) extract (AE), copper salt concentration (SC) and temperature (T) on the optimization of green synthesis of copper microparticles with respect to the maximization of the yield production and, for the first time, with respect to the minimization of the oxidation degree of the copper microparticles. Results indicate that pH and AE have greater influence on the Cu/Cu₂O microparticles yield. While the pH, AE and T have greater influence on the oxidation degree of the Cu/Cu₂O microparticles. XRD confirmed the minimization of Cu₂O phase over Cu/Cu₂O mixture, reducing Cu₂O from 83% to 31%. Spherical particles of 324–711 nm were observed and the electrical resistivity of Cu/Cu₂O (69/31 wt%) was 1.52 × 10 ⁻³ Ω.cm.

使用Taguchi方法（带有L8正交阵列）和方差分析（ANOVA）来评估pH，朝鲜蓟（Cynara scolymus L .）（朝鲜蓟）提取物（AE），铜盐浓度（SC）和温度（T）的影响。就产量的最大化和铜微粒的氧化度的最小化而言，最优化铜微粒的绿色合成。结果表明，pH和AE对Cu / Cu ₂ O微粒产率的影响更大。pH，AE和T对Cu / Cu ₂ O微粒的氧化程度影响更大。XRD证实与Cu / Cu _2相比，Cu ₂ O相的最小化O混合物，将Cu ₂ O从83％减少到31％。观察到的324-711纳米的球形颗粒和Cu / Cu的电阻率₂ O（69/31重量％）为1.52×10 ^-3 Ω.cm.
