Abstract:Objective To study the chemical constituents from the Lindera caudata(Wall.)Bench. Method The compounds of the Lindera caudata(Wall.)Benchwere separated by multi-chromatography and their chemical structures were elucidated by chemical and spectral analysis. Result Three know compounds were isolated and identified as Norpredicentrine(Ⅰ)、Lirioferine (Ⅱ)、Protosinomenine(Ⅲ),respectevely.Conclusion All the compounds were isolated from the examined sample for the first time.
Keywords:Lindrera caudate;Lauracene;Isoquinoline Aldalieds
毛葉三條筋Lindera caudata(Wall)Bench為樟科(Lauraceae)山胡椒屬(Lindera)植物,傣名為芽三英,為西雙版納州傣醫常用的民族藥,具有除風通血,化瘀止痛,續筋接骨,止血生肌之攻效。用于骨折,跌打損傷,瘀血腫痛,外傷出血,風濕病肢體關節腫痛。研究對傣藥毛葉三條筋進行化學成分的研究,從中分離到3異喹啉類生物堿個化合物:Norpredicentrine(Ⅰ)、Lirioferine (Ⅱ)、Protosinomenine(Ⅲ)。研究表明這類化合物在抗癌、抗瘧、抗炎、治療心血管疾病等方面具有明顯的作用,是開發利用這類新藥的重要資源[1]。
1儀器與材料
VG Autospec-3000Bruker 型質譜儀,AM-400、DRY-500 型核磁儀,柱色譜硅膠(100~200目,200~300目,300~400目),Sephadex LH-20。實驗樣品于2005年7月采自西雙版納州勐海縣,經中國科學院西雙版納植物園陶國達鑒定為Lindera caudata(Wall)Bench的干燥葉。所用試劑均為分析純。
2提取與分離
毛葉三條筋干燥品17 Kg,用90%乙醇提取三次,減壓回收,得總提取物。用5%鹽酸溶液調節pH至2,醋酸乙酯萃取,酸液用10%氫氧化鈉溶液調節pH至10,用三氯甲烷萃取,回收萃取液。三氯甲烷部位300 g,硅膠柱色譜分離,以氯仿-甲醇梯度洗脫,合并斑點相同部位,分為A、B、C、D、E 5個部分,其中A部分減壓濃縮后有難溶物存在,析出物反復重結晶,得到白色化合物Ⅰ(15mg), B、C、D、E部分經硅膠柱層析,制備薄層色譜反復純化得到化合物Ⅰ(6 mg),化合物Ⅱ(10 mg),化合物Ⅲ(15 mg)。
