Chemical constituents from the methanol fraction of Premna fulva leaves and their anti-inflammatory activities
【摘要】 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。
【Abstract】 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.
