High-performance liquid chromatography (HPLC) in combination with atmospheric pressure chemical ionization mass spectrometry (APcI-MS) was applied to the determination of the phenolic fraction found in methanolic extracts of sunflower seeds (mainly chlorogenic acid and derived compounds). These extracts were directly separated by HPLC and detected by both negative and positive APcI-MS. Abundant structural information about these compounds can be obtained even at low extraction cone voltages. This method has been shown to be a rapid and effective method for the analysis of crude extracts from sunflower seeds.
高效液相色谱法（HPLC）结合大气压化学电离质谱法（APcI-MS）用于测定向日葵籽甲醇提取物中的酚类成分（主要是绿原酸及其衍生物）。这些提取物通过HPLC直接分离，并通过负离子和正离子APcI-MS进行检测。即使在低提取锥电压下，也能获得有关这些化合物的丰富结构信息。该方法已被证明是分析向日葵籽粗提物的一种快速有效的方法。
