GC-MS analysis and preliminary study on structures of extracts from Fraxinus hupehensis leaves
In order to study the anti-disease cause of Fraxinus hupehensis in search of a new bio-pesticide,on the basis of the early bactericidal activity researches on extract from F.hupehensis leaves,ethyl acetate extracts and its column chromatography isolation ingredients were analyzed by GC-MS,and the possible structures of compounds contained in each ingredient were preliminarily identified.The results showed that,in ethyl acetate extracts,area normalization contents of 18 compound ingredients were over 1％,among which the No.3 compound ingredient had area normalization contents of 17.13％ and had the structure of 4-hydroxyl phenyl ethanol.Through column chromatography isolation,compounds contained in each ingredient were more concentrated and purer.Ingredient A contained two substances,and its 4-hydroxyl phenyl ethanol content reached 81.3％,which was relatively pure.According to available relevant research results,the bactericidal activity shown by Ingredient A was better than that of the others.So 4-hydroxyl phenyl ethanol,as a important compound in F.hupehensis leaves,played an important role in the anti-disease ability ofF.hupehensis.
