Objective: To determine the quality of chemical compositions in the different extracts of Engelhardtia roxburghiana leaves. Method: Rutin
gallic acid and oleanolic acid were used as the control samples. Spectrophotometry was used to determine the content of total flavonoids
total polyphenol and total saponins in the 95% alcohol extract and water extract of the leaves of E. roxburghiana. Result: The 95% alcohol extract content of total flavonoids
total polyphenols and total saponins were 48.01%
34.01% and 20.09% respectively. The content of water extract was 42.04%
33.25% and 17.84% respectively. Conclusion: This method is simple
accurate and reliable
which could be used to determine the quality of the three major chemical compositions in E. roxburghiana.
