ObJective: To investigate the chemical constituents in leaves of Lonicera Japonica. Method: Column chromatography with macroporous resin and versamide
TLC and prep-HPLC were used to isolate compounds. Physicochemical constants and spectroscopic analysis were employed for the structural elucidation. Result: Six compounds were isolated and elucidated as lonicerin(Ⅰ)
3
5-dicaffeoylquinic acid(Ⅱ)
4
5-dicaffeoylquinic acid(Ⅲ)
1
5-dicaffeoylquinic acid(Ⅳ)
β-sitosterol(Ⅴ)
β-daucosterol (Ⅵ)
Conclusion: CompoundsⅡ
compounds Ⅲ
compounds Ⅳ are isolated from Leaves of L. Japonica for the first time.
