ABSTRACT

Cycas revolute Thunb is a first class protected plant in China and has high medicinal value. As early as the Qing dynasty, it was recorded that Cycas was use to treat disease. Early research on Cycas mainly focused on classification, protection and breeding. In recent years, people began to study the main chemical constituents, chemical structure and pharmacological effects of Cycas, which laid a solid theoretical foundation for the further development and utilization of Cycas. At present, most of amentoflavone derivatives and hinokiflavone derivatives found in Cycas have the therapeutic effect on tumor. In addition to the antitumor activity, the extracts of Cycas also have antibacterial, antioxidant and immunological activities.
