Abstract
贯叶金丝桃的提取物,它可以通过用不溶于水的C1-C5醇的酯类分馏该植物的含水醇、醇或丙酮提取物得到的。
Description
本发明涉及贯叶金丝桃的提取物及其制剂，其中的贯叶金丝桃提取物可以通过不溶于水的C1-C5醇的酯类分馏该植物的含水醇、醇或丙酮提取物得到。
贯叶金丝桃开花的顶部含有许多类结构不同的物质，这些物质能够直接或间接作用于中枢神经系统。
实际上，人们早已知道贯叶金丝桃含有一系列的活性化合物如金丝桃素、贯叶金丝桃素和双黄酮，它们对动物和人具有抗抑郁和抗焦虑活性。这些化合物的作用机理是不相同的：抗MAO作用，对五羟色胺释放的作用，这些将在下文作详细描述，以及对苯二氮受体的活性。由于在文献中的所报道的对照数据，金丝桃素的活性已经讨论过很长时间。
最近，用体内药理模型已经证实有争论的金丝桃素抗抑郁活性。实际上，这早已被证实，即当有贯叶金丝桃提取物中所含的二聚原花青素存在下服用金丝桃素时，它具有活性(第45届药用植物研究组织年会，1997年9月7-12日，Regensburg，德国，V.Butterwecke等，摘要号011)。
最近贯叶金丝桃素已成为许多研究的目标，这些研究使贯叶金丝桃素作为抗抑郁药可能起了重要作用；由中请人所进行的试验证实了该分子具有类似于五羟色胺的活性。其他认为重要的组分是双黄酮，来自于为天然苯二氮类结构的芹菜甙元，这些报道见“天然存在的苯二氮类结构、分布和功能”，I.Izquierdo和J.Medicine Eds,1993，第33页。
这些产物，尤其是贯叶金丝桃素，在通常的提取和存放条件下是很不稳定的；按照WO97/13489(Schwabe)，贯叶金丝桃素在贯叶金丝桃素的水-醇提取物中的含量在几周后几乎下降为零。
按照WO97/13489，为了得到贯叶金丝桃素固定含量的稳定提取物，提取、纯化和存放应当在抗氧化剂如维生素C及其酯、硫酸化氨基酸等的存在下进行。
EP0599307(Schwabe)公开了通过聚乙烯吡咯烷酮和其他化学物质去除金丝桃素，金丝桃素起着所不希望的光敏作用；该专利公开了不使用抗氧化剂得到了至少5％贯叶金丝桃素含量的提取物。
比较甲醇的常规提取物或Commission E专题论文所述的那些与按照EP0599307和WO97/13489制备的提取物之间的药理和临床数据是没有意义的。另一方面，贯叶金丝桃素的常规提取物经验证含有大量黄酮及其他显著对提取物活性起作用的物质，其中所述的黄酮是潜在的自由基清除剂，因此对易氧化的物质来说是天然的稳定剂。
现在已经发现稳定的，特别是具有活性的贯叶金丝桃素的提取物，它含有对药理活性起作用的主要化合物，具体是金丝桃素、贯叶金丝桃素、黄酮类和呫吨酮，它可以通过这样的方法制得，该方法包括下列步骤：a)用醇或丙酮提取贯叶金丝桃的开花顶部；b)过滤该提取液并浓缩；c)用水或水/醇混合物稀释步骤b)中得到的浓缩物；d)用脂肪族的酯类提取步骤c)得到的含水混合液；e)把步骤d)得到的酯类提取液过滤并蒸发至干；并且，任选，f)用有机酸的含水乙醇溶液溶解并在40℃以下的温度蒸发该溶剂。
优选实现本发明的方法是用甲醇或乙醇进行第一次提取(步骤a)，药材与溶剂的重量/体积比在1∶2到1∶20的范围内，优选为1∶2到1∶10的范围内，温度在室温到溶剂的回流温度范围内，优选在室温至40℃。
用于步骤c)的脂肪族的酯类例如为乙酸乙酯、乙酸甲酯或乙酸丁酯；乙酸乙酯是最佳的。
用所述酯类提取是在用等体积的水或用体积比为1∶2到1∶5范围内的醇/水混合液处理浓缩的醇或丙酮提取液之后进行。
含水混合液与酯的体积比不是很严格的，能够在较宽的范围变化，但通常在1∶0.5到1∶2的范围内。
最好用新配制的等份溶剂重复进行提取，一般至少三次。
实现任选的步骤f)是把步骤e)中的浓缩物溶解在有机酸的95％乙醇溶液中，其中的有机酸如柠檬酸、苹果酸、乙酰天冬氨酸或磷酸。
按照M.Brolis等，色谱层析杂志，825(1998),9-16所分析的，当使用自然的植物生物量时，本发明所得到的提取物含有5-20％(重量)的贯叶金丝桃素，而当使用选择的植物生物量时可得到含量为10-50％(重量)的贯叶金丝桃素。在两种情况中，金丝桃素的总含量高于0.5％，而双黄酮是以1-2％(重量)的含量存在的。这种含量的较大差异取决于收集植物的时间、开花顶部的种子含量和该生物量中所存在的茎含量。
与总提取物相比，在各种用来评价抗抑郁和焦虑作用的药理模型中该提取物出人意料地具有较高活性，并且不需要进一步的特殊处理随着时间的推移活性是稳定的。
而且，本发明的方法不需要进一步处理就能够提供稳定的提取物。该提取物应当用任何方式遮光以避免光解。
所得到的提取物对五羟色胺(5-HT)的抑制和多巴胺(DA)的摄取具有下列活性。表Ⅰ-按照实施例1制备的贯叶金丝桃素的提取物对抑制3H 5-HT和3H DA摄取的作用。

这些数据清楚地表明本发明的提取物具有高于贯叶金丝桃素和其他已知提取物好几倍的功效。
在体内试验中，本发明的提取物已经显示出了比已知产品高的活性，这些已知产品主要是由醇、甲醇、己烷提取物，含有或不含金丝桃素组成；而且该提取物已经证实具有较高的可重复生产性和随着时间作用的稳定性。为了在体内试验中证实抗抑郁作用，我们选择了逃逸缺陷进展试验和按照文献中已知模型在喜好酒精的Sardinia鼠上的乙醇消耗抑制试验。
在逃逸缺陷进展试验中，本发明的提取物出人意料地显示出比已知提取物高的活性和与已知药物如米帕明的相当活性。在该试验中，把小鼠固定并使其接受柔和、短暂、不可避免的电击50分钟(预试验)。24小时后，在动物的尾部试验动物避开相同刺激的能力，在这种情况下逃逸是不可能的。在30次刺激中平均一只小鼠有26次逃逸(自然对照)，而接受过预试验刺激的动物仅有1-3次脱逸(ED对照)。由预试验所诱发的高反应性没有在用抗抑郁药如米帕明或氟西汀提前治疗1-3周的小鼠中出现。在把小鼠暴露给不可避免的压力前1小时，给小鼠口服贯叶金丝桃素提取物会产生对逃逸试验的反应性有一定增加，如果提前治疗进行1-2周时，这种增加还有提高。表Ⅱ贯叶金丝桃素提取物在2周预试验的逃逸试验中对小鼠的抗抑郁作用。物质 剂量/mg/kg 逃逸数贯叶金丝桃醇提取物 1000 16.6±2.8己烷提取物 600 17.2±1.6实施例1 200 23.3±0.4实施例1 100 18.3±0.2实施例1 50 13.3±0.4对照ed -- 1.6±0.1自然对照 -- 24.1±0.1统计分析：Kruskal-Wallis 无参数ANOVA KW=13.462 p=0.0012贯叶金丝桃醇提取物对自然 p＜0.01实施例1提取的贯叶金丝桃提取物200mg/kg对自然 n.s.自然对AND p＜0.01
在按照文献已知的步骤对Sardinia小鼠的醇消耗的减少(这是抑郁和焦虑的标志)试验中，在服用3天后，与对照相比，本发明的提取物诱发了醇消耗下降75％且更倾向饮用水，而用甲醇或己烷提取物治疗后醇消耗的下降分别是30和40％。
本发明的提取物能够包括在口服制剂中，如备用溶液、软或硬明胶胶囊、片剂和控释片。在制剂中提取物的剂量在常用剂型中10到100mg/剂量和在控释制剂中高达300mg的范围内，在这种情况优选剂量是每天300mg/剂量。
