Abstract

Based on the nucleophilic addition reaction between cinnamaldehyde and bisulfite, this study develops an analytical method for determining the cinnamaldehyde content in cinnamon essential oil using iodometric back-titration. Cinnamaldehyde reacts quantitatively with excess bisulfite, and the unreacted bisulfite is titrated with iodine. The method demonstrated a strong linear relationship (R² = 0.9999) within the concentration range of 2–15 mg/mL, with a detection limit of 0.32 mg/mL and a quantification limit of 1.07 mg/mL. Recovery tests using Chinese and Ceylon cinnamon essential oils showed recovery rates between 96.0 and 99.4%, with intra-day and inter-day relative standard deviations below 2%. The results were consistent with those obtained by gas chromatography. The method is accurate, reproducible, and cost-effective, and does not require sophisticated instrumentation, making it widely applicable for quality control and authenticity assessment of cinnamon essential oils. This work provides a low-cost and reliable method for the determination of cinnamaldehyde in cinnamon essential oil.

亚硫酸氢盐碘量法测定肉桂精油中的肉桂醛

基于肉桂醛与亚硫酸氢盐的亲核加成反应，建立了用碘量反滴定法测定肉桂精油中肉桂醛含量的分析方法。肉桂醛与过量亚硫酸根定量反应，未反应亚硫酸根用碘滴定。方法在2 ~ 15 mg/mL浓度范围内呈良好的线性关系（R2 = 0.9999），检出限为0.32 mg/mL，定量限为1.07 mg/mL。中国肉桂精油和锡兰肉桂精油的回收率在96.0 ~ 99.4%之间，日内和日内相对标准偏差低于2%。结果与气相色谱法一致。该方法准确、重复性好、成本效益高，不需要精密仪器，可广泛应用于肉桂精油的质量控制和真实性评估。为测定肉桂精油中肉桂醛的含量提供了一种低成本、可靠的方法。
