Analysis of the Content and the Components of Flavonoids in Torreya jackii

Abstract

The content of flavonoids in different nutritious organs of Torreya jackii and three kinds of nutritious organs of Torreya jackii with different populations was determined and the components of the flavonoids were analyzed by using the method of polyacrylamides membrane chromatography. The results showed as follow: (1) Flavonoids was found in all kinds of nutritious organs of Torreya jackii and the content was in a decreasing order of annual leaves, annual stalk, rootlet, taproot, bark, perennial stalk and stem. (2) There was very different in the components of flavonoids in different nutritious organs of Torreya jackii. Annual leaves and annual stalk had the most of components, rootlet took the second place, taproot and perennial stalk were the third, bark and stem had the least of components. (3)There was different in the content of flavonoids in three kinds of nutritious organs of Torreya jackii with different populations. In all, annual leaves had the highest content of flavonoids while annual stalk took the second place and perennial stalk had the lowest content of flavonoids. (4) There was no significant difference in the content of flavonoids in annual leaves of Torreya jackii with different populations. But there was relatively high different in the content of flavonoids in annual stalk and perennial stalk. )5) Annual leaves of Torreya jackii with different populations had no difference in the components of flavonoids, while annual stalk had little different and perennial stalk had great different.
