There is provided a method for manufacturing inexpensive, highly safe, highly stable, versatile polymethoxyflavones that can be used in food products and easily incorporated into a variety of pharmaceutical formulations, whereby in one pass, a large quantity of polymethoxyflavones can be isolated from other components in citrus peel oil, as well as a method for its use. The method for manufacturing polymethoxyflavones from citrus plant peel oil comprises a step of removing the volatile components in citrus plant peel oil by distillation to obtain a distillation residue, a step of distilling the residue with a thin-film vacuum distillation apparatus to obtain a fraction, a step of extracting the fraction with an aqueous ethanol solution to obtain an extract, and a step of contacting active carbon with the extract after removal of the insoluble oils in the extract for refining, as a method for manufacturing polymethoxyflavones that are highly stable over time and have reduced residual pesticide levels.
本发明提供了一种用于制造廉价、高度安全、高度稳定、用途广泛的聚甲氧基黄酮的方法,这种聚甲氧基黄酮可用于食品中,也可方便地加入各种药物制剂中,通过这种方法,可以一次性地从柑橘皮油中的其他成分中分离出大量的聚甲氧基黄酮,同时还提供了一种使用方法。从柑橘类植物果皮油中制造多甲氧基黄酮的方法包括:第一步,用蒸馏法去除柑橘类植物果皮油中的挥发性成分,得到蒸馏残渣;第二步,用薄膜真空蒸馏装置蒸馏残渣,得到馏分、用乙醇水溶液萃取该馏分以获得萃取液的步骤,以及在去除萃取液中的不溶油后将活性碳与萃取液接触以进行精炼的步骤,以此作为制造长期高度稳定且残留农药水平较低的聚甲氧基黄酮的方法。
