摘要

目的:研究金银花二氯甲烷提取物的化学成分。方法:采用硅胶柱层析、Sephadex LH-20凝胶柱层析、重结晶等方法对化合物进行分离纯化。通过理化性质、质谱、1H-NMR和13c - nmr对其结构进行了表征。结果:共分离得到9个化合物，结构鉴定为β-谷甾醇(1)、苯甲酸(2)、5-羟基-7,3′，4′-三甲氧基黄酮(3)、四萜酸B(4)、tricin(5)、hydrocarpin D(6)、6,7,10-三羟基-8-十六烯酸(7)、5′-甲氧基hydroxycarpin -D(8)和二芥子甾醇(9)。结论:化合物2、4、7、8为从该植物中分离得到，化合物2、7、8为首次从辣椒科植物中分离得到。

[Chemical Constituents of Lonicerae Japonicae Flos].

Objective: To study the chemical constituents of the methylene chloride extract of Lonicerae Japonicae Flos.

Methods: The compounds were isolated and purified by silica gel column chromatography,Sephadex LH-20 gel column chromatography and recrystallization. The structures were elucidated by the physical and chemical properties,MS,1H-NMR and13C-NMR spectroscopy.

Results: Nine compounds were isolated and their structures were identified as β-sitosterol( 1),benzoic acid( 2),5-hydroxy-7,3’,4’-trimethoxyflavone( 3),tetrapedic acid B( 4),tricin( 5),hydnocarpin D( 6),6,7,10-trihydroxy-8-octadecenoic acid( 7),5’-methoxyhydnocarpin-D( 8) and daucosterol( 9).

Conclusion: Compound 2,4,7,8 are isolated from this plant,compounds 2,7,8 are isolated from Caprifoliaceae family for the first time.
