摘要
目的 用反相液相色谱 -电喷雾质谱 (RP- HPL C/ ESI- MS)分析葡萄籽粗提物中低聚原花青素的组成。方法根据质谱的准分子离子 [M- H](m/ z)检测其单体及低聚体。结果 初步检测出 3个单体、7个二聚体及 3个三聚体。结论 表明 RP- HPL C/ ESI- MS联用可以分析葡萄籽原花青素低聚体的基本组成。
Object The analysis of oligomeric procyanidins in crude grape seed extracts was performed by reversed-phase high-performance liquid chromatography with electrospray ionization mass spectrometry (RP-HPLC/ESI-MS). Methods Procyanidin monomer and oligomers were identified according to the mass of the charged pseudomolecular ion [M-H]. Results Three monomers, seven dimmers and three trimers were tentatively identified. Conclusion This study demonstrates the capability of the combination of RP-HPLC with ESI-MS to analyze the composition of oligomeric procyanidins in grape seed extracts.
