紫锥菊原产于美国、加拿大南部等地,后引入我国,作为免疫调节剂和免疫促进剂,可用于预防感冒,治疗咳嗽、支气管炎和上呼吸道感染[1-2]。紫锥菊的活性成分菊苣酸(Cchoric Aid,CA)具有抗病毒、消炎、提高免疫力等作用,是近年来的研究热点;但菊苣酸为有机弱酸,不稳定,在使用中易氧化失效,且难溶于水而导致使用不方便。新型包被材料羟丙基-β-环糊精(HP-β-CD)属于环糊精衍生物之一,因 Echinacea native to the United States, southern Canada and other places, after the introduction of our country, as an immunomodulator and immune enhancer, can be used to prevent colds, cough, bronchitis and upper respiratory tract infections [1-2]. Echinacea active ingredient Cchoric acid (Cchoric Aid, CA) with anti-virus, anti-inflammatory, improve immunity and so on, is a research hotspot in recent years; but the acid is weak organic acid, unstable, easy to use in the failure, and difficult Dissolved in water and cause inconvenience. The novel coating material hydroxypropyl-β-cyclodextrin (HP-β-CD) is one of cyclodextrin derivatives, due to
