From an aqueous extract of Lonicera japonica flower buds, sixteen compounds were isolated by a combination of various chromatographic techniques including column chromatography over macroporous resin, MCI gel, silica gel, and sephadex LH-20 and reversed-phase HPLC. Their structures were elucidated

Allergy-preventive activity of flower buds of Lonicera japonica THUNB. was found in the 35% EtOH extract (LJ) using an in vivo assay, The assay system uses monitoring of a decrease in blood flow (BF) in the tail vein of mice subjected to sensitization with hen-egg white lysozyme (HEL).

OBJECTIVE To research the chemical constituents from stems and leaves of Lonicera macranthoides. METHODS Various column chromatographies were employed to isolate and purify the constituents. Their structures were elucidated by spectral analysis (IR, MS, 1H-NMR, 13 C-NMR) and chemical

Lonicerae japonicae flos (LJF) and Lonicerae japonicae caulis (LJC) are derived from different parts of Lonicera japonica Thunb. (Caprifoliaceae), and have been used as herbal remedies to treat various diseases for thousands of years with confirmed curative effects. However, little attention
