目的 研究战骨叶甲醇部位的化学成分及其抗炎活性.方法 战骨叶甲醇部位采用薄层色谱、柱色谱和HSCCC进行分离纯化,根据理化性质及波谱数据鉴定所得化合物的结构.采用RAW264.7模型评价其体外抗炎活性.结果 从中分离得到12个化合物,分别为鉴定为牡荆素(1)、balanophonin(2)、桦褐孔菌二糖(3)、4-allyl-2,6-dimethoxyphenol-β-D-glucopyranoside(4)、去氢催吐萝芙木醇(5)、地芰普内酯(6)、(E)-4-((1S,3R,4R)-1-hydroxy-4,5,5-trimethyl-7-oxabicyclo[4.1.0]heptan-1-yl)but-1-en-3-o-ne(7)、(E)-4-hydroxyphenylprop-7-ene 4-O-β-D-glucopyranoside(8)、4-羟基苯甲酸4-O-β-D-吡喃葡萄糖苷(9)、vicenin(10)、齐墩果酸(11)、芝麻素(12).化合物 1、2、5、7、10、12 对 NO 均具有良好的抑制活性,IC50值分别为(26.42±2.5)、(21.24±2.2)、(25.88±1.9)、(29.72±2.1)、(8.90±1.1)、(9.73±0.7)μmol/L.结论 化合物2、4~8为首次从豆腐柴属植物中分离得到.化合物1、2、5、7、10、12具有抗炎活性.
Chemical constituents from the methanol fraction of Premna fulva leaves and their anti-inflammatory activities
AIM To study the chemical constituents from the methanol fraction of Premna fulva Craib leaves and their anti-inflammatory activities.METHODS The methanol fraction from P.fluva were isolated and purified by TLC,column chromatography,and HSCCC,then the structures of obtained compounds were identified by physicochemical properties and spectral data.Their anti-inflammatory activities in vitro were evaluated by RAW264.7 model.RESULTS Twelve compounds were isolated and identified as vitexin(1),balanophonin(2),inotodisaccharide(3),4-allyl-2,6-dimethoxyphenol-β-D-glucopyranoside(4),dehydrovomifoliol(5),loliolide(6),(E)-4-((1S,3R,4R)-1-hydroxy-4,5,5-trimethyl-7-oxabicyclo[4.1.0]heptan-1-yl)but-1-en-3-o-ne(7),(E)-4-hydroxyphenylprop-7-ene 4-O-β-D-glucopyranoside(8),4-O-β-D-glucopyranosylbenzoic acid(9),vicenin(10),oleanicacid(11),sesamin(12),respectively.Compounds 1,2,5,7,10,and 12 showed good inhibitory activities against NO,and the IC50 values were(26.42±2.5)、(21.24±2.2)、(25.88±1.9)、(29.72±2.1)、(8.90±1.1)、(9.73±0.7)μmol/L,respectively.CONCLUSION Compounds 2,4-8 are isolated from Premna genus plants for the first time.Compounds 1,2,5,7,10,12 have anti-inflammatory activities.
