Method for isolating flavonoids from rice plant inoculated with whitebacked planthopper

The present invention relates to a method for isolating flavonoids such as cochlioquinone or chrysoeriol from a rice plant inoculated with a whitebacked planthopper. The method of the present invention， for example， facilitates not only the fast production of flavonoids such as cochlioquinone or chrysoeriol but also the mass-production of flavonoids such as cochlioquinone or chrysoeriol with high efficiency in addition to the advantage of saving costs. Therefore the method of the present invention can be effectively used for the production of flavonoids such as cochlioquinone or chrysoeriol and also be used in various fields using the same.

本发明涉及一种从接种白背飞虱（whitebacked planthopper）的水稻植株中分离类黄酮（flavonoids）的方法，所述类黄酮包括壳二孢菌素（cochlioquinone）与金圣草黄素（chrysoeriol）等组分。举例而言，本发明所述方法不仅可实现该类类黄酮的快速制备，还能兼具成本节约的优势，以高效方式实现大规模量产。因此，本发明方法可有效应用于壳二孢菌素、金圣草黄素等类黄酮的制备，并可拓展至以该类物质为核心的各类应用领域。
