| 中文摘要: |
| 采用高效液相色谱法分析亚麻籽环肽组成及相对含量。以14种亚麻籽环肽色谱峰平均分离度和分析效率作为指标，对不同色谱柱、进样量、梯度洗脱初始体积分数、流速、乙腈体积分数上升速率进行优化，并利用HPLC-ESI-MS进行定性分析。结果表明，高效液相色谱最优条件为：采用Kinetex色谱柱，水、乙腈为流动相，进样量5 μL，梯度洗脱程序为乙腈体积分数从40%以5%/min 升至90%，流速1 mL/min。最优条件下亚麻籽环肽14个色谱峰分离度较好，平均分离度为165，分析时间为9.09 min，分离效率为10.86。优化后的色谱条件可对市售亚麻籽、亚麻籽油以及亚麻籽粕中环肽组成进行有效分析。 |
| 英文摘要: |
| The composition and relative content of cyclolinopeptides were analyzed by high performance liquid chromatography (HPLC). HPLC parameters(chromatographic column,injection volume, initial elution volume fraction, flow speed and increase rate of acetonitrile volume fraction) were optimized with the average degree of separation and separation efficiency of 14 kinds of cyclolinopeptide peaks as an index. Cyclolinopeptides were qualitatively determined by HPLC-ESI-MS. The results showed that the optimal HPLC parameter were obtained as follows: Kinetexchromatographic column, water and acetonitrile as the mobile phase, flow rate 1 mL/min, injection volume 5 μL, elution programming of acetonitrile volume fraction increasing from 40% to 90% at 5%/min. 14 peaks of cyclolinopeptides had good separation, and the average degree of separation,analysis time and separation efficiency were 1.65, 9.09 min and 10.86, respectively. The optimal HPLC conditions could be applied in the determination of cyclolinopeptides composition of commercial flaxseed, flaxseed oil and flaxseed meal. |
