目的:研究傣藥毛葉三條筋中的化學(xué)成分。方法:利用各種色譜技術(shù)進(jìn)行分離純化,根據(jù)各種波譜數(shù)據(jù)和文獻(xiàn)數(shù)據(jù)對照進(jìn)行結(jié)構(gòu)鑒定。結(jié)果:分離鑒定三個(gè)化合物,均為生物堿,分別為 Norpredicentrine(Ⅰ)、Lirioferine (Ⅱ)、Protosinomenine(Ⅲ)。結(jié)論:三個(gè)化合物均為首次從毛葉三條筋中分離得到。
傣藥毛葉三條筋;樟科;山胡椒屬;異喹啉生物堿
毛葉三條筋Linderacaudata(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(yī)常用的民族藥,具有除風(fēng)通血,化瘀止痛,續(xù)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(fēng)濕病肢體關(guān)節(jié)腫痛。研究對傣藥毛葉三條筋進(jìn)行化學(xué)成分的研究,從中分離到3異喹啉類生物堿個(gè)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(fā)利用這類新藥的重要資源[1]。
VG Autospec-3000Bruker 型質(zhì)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(shí)驗(yàn)樣品于2005年7月采自西雙版納州勐??h,經(jīng)中國科學(xué)院西雙版納植物園陶國達(dá)鑒定為Linderacaudata(Wall.)Bench的干燥葉。所用試劑均為分析純。
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(diào)節(jié)pH至2,醋酸乙酯萃取,酸液用10%氫氧化鈉溶液調(diào)節(jié)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(diǎn)相同部位,分為A、B、C、D、E 5個(gè)部分,其中A部分減壓濃縮后有難溶物存在,析出物反復(fù)重結(jié)晶,得到白色化合物Ⅰ(15mg), B、C、D、E部分經(jīng)硅膠柱層析,制備薄層色譜反復(fù)純化得到化合物Ⅰ(6 mg),化合物Ⅱ(10 mg),化合物Ⅲ(15 mg)。
