技术领域
本发明涉及中药提取、分离领域,尤其涉及从马齿苋药材中提取、分离和鉴别出的一种新生物碱类化合物及其提取分离方法。
背景技术
马齿苋(Portulaca oleraceaL.),又名长命菜、马苋菜,为马齿苋科植物。马齿苋性喜肥沃土壤,耐旱亦耐涝,生命力强,分布广泛,资源丰富,而以我国东北部的更为常见。马齿苋既可入药,又可食用,是我国卫生部划定的药食同源的野生植物之一。马齿苋的干燥地上部分入药,具有清热解毒、凉血止血、止痢等功效,用于热毒血痢、痈肿疔疮、湿疹、丹毒、蛇虫咬伤、便血、痔血、崩漏下血等。
现代药理学研究表明,马齿苋具有降血脂、降血糖、抗炎、抗氧化、抗肿瘤、抗动脉粥样硬化、松弛或兴奋平滑肌及增强免疫力等功效。研究表明马齿苋中所含多种化学成分与其多样的药理作用息息相关,其主要化学成分包括:黄酮类、生物碱类、萜类、香豆素类、有机酸类、挥发油、多糖、氨基酸、各种色素类和矿物质类等。其中生物碱是马齿苋中的一大类活性成分,目前已报道的生物碱类成分有去甲肾上腺素、多巴胺、少量多巴、腺苷、尿嘧啶、腺嘌呤、N,N-二环己基脲、尿囊素、N-反式-阿魏酰基酪胺;还有环二肽生物碱和酰胺类生物碱:马齿苋酰胺A-I、K、L、N-S。
目前从马齿苋中分离出的化学成分大多数是已知的,且结构新颖性较低,因此,对马齿苋中新化合物的开发和研究其活性是亟待需要的。
发明内容
针对上述问题,本发明提供马齿苋中提取的一种新天然产物,经研究发现本发明的一种新天然产物具有抗炎和抗胆碱酯酶的作用,同时提供一种针对本发明新天然产物的简便、快速、环保、纯度高的提取分离方法。
为实现本发明的上述目的,本发明提供两种新生物碱类化合物,分子式分别为C15H25NO6和C9H15NO,并分别命名为(Z)-2-((1-(1H-azirin-1-yl)-5-methylhex-1-en-3-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol和(Z)-1-(1H-azirin-1-yl)-5-methylhex-1-en-3-ol,化学结构式分别为:
。
为实现本发明的上述目的,本发明还提供马齿苋中两种新生物碱类化合物(Z)-2-((1-(1H-azirin-1-yl)-5-methylhex-1-en-3-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol和(Z)-1-(1H-azirin-1-yl)-5-methylhex-1-en-3-ol的提取分离方法,具体步骤为。
步骤1、取马齿苋干燥药材,采用水煎煮提取两次,水提液滤过,合并滤液直接加热浓缩,放凉至室温,得药液备用;
步骤2、将步骤1中药液蒸干后上AB-8大孔树脂,其中大孔树脂16-60目,采用乙醇-水梯度洗脱,20%乙醇部分浓缩蒸干后得浓缩物备用;
步骤3、将步骤2中所得浓缩物经预处理的ODS柱(Octadecylsilyl,十八烷基硅烷键合硅胶填料)层析分离,填料粒度为40~70μm,用甲醇-水梯度洗脱,得到若干洗脱部位,经薄层色谱进行检测,显色,将显色部位分别减压浓缩至干,得浓缩物备用;
步骤4、将步骤2中所得浓缩物再经预处理的ODS柱(Octadecylsilyl,十八烷基硅烷键合硅胶填料)层析分离,填料粒度为40~70μm,用甲醇-水梯度洗脱,得到若干洗脱部位,经薄层色谱进行检测,显色,将显色部位分别减压浓缩至干,得浓缩物备用;
步骤5、将步骤3中所得浓缩物经预处理的Sephadex LH-20(羟丙基葡聚糖凝胶)层析分离,用10%甲醇等度洗脱,经薄层色谱进行检测,显色,将显色的洗脱部位分别减压浓缩至干,得浓缩物备用;
步骤6、将步骤5中所得浓缩物通过HPLC(高效液相)分离制备,以甲醇-0.1%甲酸水为流动相进行等度洗脱,最终得到本发明所述的两种新生物碱。
所述ODS的预处理过程为甲醇浸泡过24小时,上柱,用甲醇洗至滴入水中无混浊,再以初始流动相平衡。
所述Sephadex LH-20凝胶的预处理过程为甲醇浸泡过24小时,上柱,以初始流动相平衡。
与现有技术相比本发明的有益效果。
本发明中所述马齿苋中两种新生物碱的分离和药理活性研究未被发现有论文期刊所报道;本发明提供来源于马齿苋的两种新生物碱类化合物及一种针对本发明化合物的提取分离方法,依次采用水煎煮提取、大孔树脂柱、ODS中压柱、Sephadex LH-20及HPLC进行分离纯化与制备,从马齿苋中提取分离出两种新生物碱,该方法操作步骤仅为六步,操作方法简便及快速,提取分离过程主要采用水煎煮,工艺方法环保,且经该方法分离得到的化合物纯度较高均大于90%,此外经研究表明以上化合物具有抗炎和抗胆碱酯酶作用,因此本发明两种新生物碱类化合物及其盐和衍生物可以作为其他化合物合成先导物,以及新药开发和药理活性研究的原料,亦可用于制备抗炎和抗胆碱酯酶的药物。

下面结合具体实施例对本发明做详细的说明。
实施例1。

表1:本发明生物碱类化合物(Z)-2-((1-(1H-azirin-1-yl)-5-methylhex-1-en-3-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol的核磁数据

本发明生物碱化合物(Z)-1-(1H-azirin-1-yl)-5-methylhex-1-en-3-ol的结构鉴定与推导。
得到的化合物为黄色油状物质,易溶于甲醇,不溶、微溶于水。分子量为152.1080。点样于硅胶薄层板后,喷稀碘化铋钾试液斑点显橘黄色,提示该化合物为生物碱成分。结合1H-NMR,13C-NMR以及DEPT数据,推测该化合物可能的分子式为C9H15NO,不饱和度为3。
13C-NMR谱、HMBC谱和DEPT谱显示9个碳信号,分别为2个CH3(δC22.82,21.31),1个CH2(δC41.43),6个CH(δC134.29,132.67,131.60,127.54,73.69, 24.76)。在1H-NMR谱中,δH0.79(d,J=5.52Hz),δH0.73(d,J=5.64Hz)证明两个甲基的存在。δH1.97(s)证明个亚甲基的存在。δH8.52(s),8.37(s),δH7.72(s),δH7.71(s),δH4.99(s),δH1.07(s)证明6个次甲基存在。
通过13C-NMR谱图可以看出C-2(δC132.6,7),C-3(δC131.60)和C-4(δC134.29)具有低场化学位移,根据δH8.52(s,1H),δH7.72(s,1H)和δH8.37(s,1H)处的信号,可以说明C-2,C-3,C-4和与N原子相连。在HMBC光谱中,C-3与H-2(δH8.52),H-4(δH8.36)相关。C-4(δC135.02)与H-2(δH8.52),H-3(δH7.72),H-5(δH7.71)相关,证明存在一个含N的三元杂环。C-6(δH72.48)具有低场化学位移,说明C-6与羟基相连。根据HMBC的相关性可知,C-6(δC72.48)与H-4(δH8.36)相关。C-7(δC40.72)与H-5(δH7,71),H-9(δH0.79),H-10(δH0.73)相关。
根据以上信息,可以确定此化合物(Z)-1-(1H-azirin-1-yl)-5-methylhex-1-en-3-ol的结构。
