Phenolic compounds in roots and branches of lilac

In this study,we determined the content of total phenolics,tannin and total flavones in root and branches of lilac( Syringa oblate) with spectrophotometry. The content of total polyphenol in root and branches was( 96. 57 ± 3. 91) mg / g and( 172. 15 ± 12. 26) mg / g respectively; tannin content was( 10. 56 ± 0. 49) mg / g and( 23. 64 ± 1. 52) mg / g respectively; total flavones was( 13. 56 ± 1. 71) mg /g,( 21. 83 ± 1. 13) mg /g respectively. Paired sample t test showed that content of the three kinds of phenolic compounds were all significantly difference in root and in branches. Leaf showed higher content in total polyphenol,tannin and total flavones. Compared with other medicinal plants,Syringa oblata possess relatively higher phenolic compounds contents. In conclusion,Syringa oblata is a promising treasure in pharmacology research and medicine development.
