摘要:

目的:测定花生根茎叶中白藜芦醇的含量。方法:建立花生根、茎、叶一步硅胶柱预处理、HPLC 法测定其中白藜芦醇含量的方法。色谱柱为Hypersil ODS-2(4.6mm × 250mm,5μm),流动相为甲醇- 水(45:55,V/V),流速为0.8ml/min,柱温为35℃,紫外检测波长为306nm。线性范围:0.228~1.14μg(其相关系数R=0.9999),检测限4.3ng(3σ)。结果:测得山东、江苏和河北产花生根茎叶混合物中白藜芦醇的含量分别为903.69、116.21、88.69μg/g;山东产花生不同部位花生根、茎和叶中白藜芦醇的含量分别为223.08、1211.19、429.79μg/g;平均回收率为99.6%,RSD 为3.09%(n=5)。结论:该方法简便、快速、准确。

Abstract:

Objective: To determine the contents of resveratrol in roots, stems and leaves of peanut. Methods: A HPLC determination combined with one-step pretreatment by silica gel column chromatography was established. The analysis was achieved by separation on an Hypersil ODS-2 column (4.6 mm × 250 mm, 5 μm) at 35 ℃ using a methanol-water (45:55, V/ V) mobile phase at a flow rate of 0.8 ml/min followed by UV detection at 306 nm. Results: The contents of resveratrol in the mixtures of roots, stems and leaves of peanuts from Shandong, Jiangsu and Hebei provinces were 903.69, 116.21 and 88.69 μg/g, respectively. The contents of resveratrol in roots, stems and leaves of peanut from Shandong province were 223.08, 1211.19 and 429.79 μg/g, respectively. The calibration curve was well linear over the concentration range from 0.228 to 1.14 μg (R = 0.9999), and the limit of detection was 4.3 ng (3σ). The average recovery was 99.6%with a RSD of 3.09% (n = 5). Conclusions: This method is simple, fast and accurate.
