Abstract: The objective of this study was to determine the content of total lignans,forsythiaside A,forsythiaside B and phillyrin in Forsythia suspensa leaves from Henan province and Shanxi province.The total lignans of F.suspensa leaves from Shanxi province were higher than Henan province by spectrophotometry method.The contents of forsythiaside A,forsythiaside B and phillyrin were determined by HPLC.The average recoveries of forsythiaside A,forsythiaside B and phillyrin were 99.6% (RSD=1.23%),101.3% (RSD=1.74%) and 102.3% (RSD=2.58%),respectively.The experimental results showed that the content of forsythiaside A and phillyrin in F.suspensa leaves from Shanxi and Henan was relatively high.In addition,the content of phillyrin in F.suspense leaves from different habitats were of large difference. F.suspensa leaves are rich in forsythiaside and lignans,more researches on F.suspensa leaves are still needed to confirm whether it can be used as substitute or cooperate with F.suspensa fruit for medicinal application.

Key words: Forsythia suspensa leaves, total lignans, forsythiaside A, forsythiaside B, phillyrin
