have been widely used in China, which may be related to abundant
organic compounds, especially flavonoids. Flavonoids are found to
be the main active compounds in C. paliurus , which have many biological activities, such as
preventing hyperglycemia, diabetes mellitus, hypertension and
coronary heart disease. Many flavonoids were isolated from
