欧鼠尾草橙子（Maclua pomifera [Raf.] Schneider）含有至少4种具有抗氧化活性的色素。Pomiferin以干果的3-4%存在，并且占甲醇提取物活性的20-25%。还存在一种未鉴定的物质，其与pomiferin协同反应，使其对总活性的贡献增加至约75%。这3种新色素占干果的0.5 - 0.75%，在相同浓度下测试时，其抗氧化活性超过了果黄素。本文提出了一种用无水硫酸镁柱层析分离异黄酮类色素的新方法。
Osage orange tree fruit (Maclua pomifera [Raf.] Schneider) contains at least 4 pigments with antioxidant activity. Pomiferin was present as 3-4% of the dry fruit and was responsible for 20-25% of methanol extract activity. An unidentified substance was also present which reacted synergistically with pomiferin, increasing its contribution to the over-all activity to about 75%. The 3 new pigments, totalling 0.5 to 0.75% of the dry fruit, showed antioxidant activity exceeding pomiferin when tested at equal concentrations. A chromatographic procedure, employing anhydrous magnesium sulfate, was developed and applied successfully in separating mixtures of several iso-flavone pigments.
