| Abstract: | Procyanidins refers to the general name of new type of oligomeric flavane compounds which is formed around in cores,skins and seeds of various plants.With methanol as solvent and catechin as standard,the procyanidins in Pinus tabulaeformis needles and bark was determined with the vanillin-hydrochloric acid method.The results showed that the content of procyanidins in Pinus tabulaeformis needles and bark was 6.0 g/100g and 3.91 g/100g,respectively. |
