Description
本发明专利申请是由2002年9月5日申请的发明名称为“抗抑郁组合物及其制备方法”(申请号02138217.4)专利的分案申请。
一、技术领域：
本发明涉及天然植物有效成分的组合物及其制备方法和药物用途，特别是涉及将茯苓多糖和姜油的组合物制备成治疗抑郁症的药物。
二、背景技术：
抑郁症指情感性精神障碍综合症，以心境低落为主要特征。临床主要表现为抑郁心情、疲劳感、快感缺乏、思维和运动迟滞，伴有焦虑、睡眠障碍、食欲不振、绝望及自杀妄想等。抑郁症是危害全人类身心健康的常见病、多发病。据世界卫生组织精神病流行情况调查报告，全世界抑郁症患病率高达3～5％，重性抑郁症患者自杀率高达15～18％，终身罹患率高达8～12％(男)、20～25％(女)。在临床上，抑郁症常与其它严重疾病如心脏病、脑中风、癌症、免疫性疾病等并存。有关抑郁症流行病学的研究表明：随着世界范围的社会工业化、都市化进程的加快，社会生活中应激因素大大增多，抑郁症患病率在不断上升，患病人群日益扩大，其中在老年人群中的发病将更为突出。抑郁症将成为21世纪人类面临的主要病症之一。
抑郁症流行趋势的严重性以及患者因精神障碍所致心理素质的下降和社会功能的损害，已引起世界各国的广泛重视。世界范围内对抗抑郁药品的需求量日益增大，近年来该类药品全球市场销售量以每年16.2％的速度增长。抑郁症的防治和抗抑郁新药的研制已成为当今国际医药界前沿热点研究课题之一。
抑郁症病因复杂，与生理心理密切相关，至今仍未明确。可能与长期应激和情感引发的大脑5-羟色胺(5-HT)、去甲肾上腺素(NE)等单胺类神经递质代谢及功能失调有关，通过过度激活SAM(sympathetic adrenal-medullary)系统、HPA(hypothalamic-pituitary-adrenocortical)系统，与内分泌系统和免疫系统相联，介导相关的行为和生理效应。
目前临床治疗抑郁症的西药有多种。单胺氧化酶抑制剂(MAO-AI)(如吗氯贝胺)对中枢单胺类神经递质降解起抑制作用；5-羟色胺重摄取抑制剂(SSRI)(氟西汀)，则选择性抑制5-HT再摄取；而5-羟色胺-去甲肾上腺上素重摄取抑制剂(SNRI)(如venlafaxine)可选择性地抑制5-HT和NE重吸收；双重作用于5-羟色胺环节的抗抑郁药(如奈法唑酮)既抑制5-HT的重摄取又阻断突触后5-HT2受体；NE和DA重摄取抑制剂(如bupropin)选择性抑制NE和DA重摄取。这些药物大多因其本身作用特点所限，存在抗抑郁谱较窄、毒副作用较大、价格高昂、停药后易复发等缺点。
中医郁证指情志不宁、气机郁滞引起的一类病证，与西医的抑郁症有许多共通之处。中药含多种活性成分，可从整体上调节各系统，达到安全治愈的效果。已陆续报道了小柴胡汤(柴胡、酒黄芩、党参、姜半夏、甘草、生姜、大枣)、半夏厚朴汤(半夏、厚朴、茯苓、生姜、苏叶)及白金散(白矾、郁金、九节菖蒲、硃砂、人造牛黄)治疗“梅核气”、抑郁症、抑郁性精神病；胡思荣用平心忘忧汤(磁石、礞石、枳实、黄柏、半夏、厚朴、朱茯苓、神肉、肉桂、苏叶、菖蒲、生姜)治疗抑郁症470例，痊愈70.2％，好转20.2％，总有效率90.4％；赵志升自拟中药‘抑虑康’胶囊治疗抑郁，总体疗效优于西药对照组；马云枝等人用舒郁调神汤(柴胡、郁金、菖蒲、枳实、桃仁、红花、柏子仁、远志、煅龙牡、丹参)治疗中风后抑郁症，其治愈率为39.06％，显效率为30.40％，有效率为21.09％，无效率为9.45％，并明显改善主要及伴随症状；日本尾崎哲发现小建中汤(桂芝、生姜、芍药、甘草、大枣、饴糖末)对抑郁性神经症患者情绪具有调节作用；研究还发现柴胡加龙骨牡蛎汤(柴胡、半夏、桂枝、茯苓、黄苓、大枣、人参、牡蛎、龙骨、生姜)治疗有效性表现在疲劳、头痛、眩晕等植物神经性症状方面无显著性差异，侧重治疗抑郁、紧张。
上述传统中药复方起效慢，组份比较复杂，药效不够显著，难以制定和实施严格的质量控制标准。
茯苓为多孔菌科Poria cocos(Schw.)Wolf的干燥菌核，多糖可占干重的80-93％，主要为β-茯苓聚糖等。《药性论》记载，茯苓“开胃，止呕逆，善安心神”，具有益脾和胃、宁心安神之功效。生姜为姜科Zingiber officinale Rosc的鲜根茎，含挥发油0.25-3.0％，其中主要成分为姜醇、姜烯、水芹烯、莰烯等。《食疗本草》记载，生姜“止逆，散烦闷，开胃气”，药理试验表明，茯苓多糖有显著的镇静作用和免疫调节功能，并具有抗肿瘤作用。姜油中6-姜烯、6-姜酚、6-姜烯醇为主要成分，具有中枢神经系统抑制作用以及抗氧化、抗肿瘤、抗炎和保护胃粘膜等多种作用。
三、发明内容：
1.发明目的
本发明的目的就是为了解决上述问题，而提供一种由茯苓多糖和姜油两种成分制备成的组合物及其制备方法，以及在制备治疗抑郁症药物中的应用。
2.技术方案
本发明的药物组合物，其特征在于它是由以下重量配比的植物提取物组分所组成：茯苓多糖3.5-14g、姜油0.2-3.5g；上述提取物组分优选的用量为，厚朴酚性成分0.4g、茯苓多糖10.0g和姜油1.0g。
各组分混合后可与β-环糊精等量混合，以增加组合物组份的稳定性。β-环糊精的用量也可以根据具体情况在适当范围内变化。
本发明的药物组合物的制备方法，其步骤为：
(1)茯苓经水提取后，浓缩液中加95％乙醇至乙醇浓度为50-80％，所得沉淀即为茯苓多糖；
(2)生姜用超临界CO2萃取、石油醚提取、水蒸气蒸馏或水煎煮提取得姜油；
(3)茯苓多糖3.5-14g、姜油0.2-3.5g，用β-环糊精包合姜油后混合即得组合物PG。
然后在组合物PG中加入适量的辅料，可制成片剂、颗粒剂或胶囊剂等口服制剂。这些剂型是按照本领域的技术人员所熟知方法制备的。用于制造片剂、颗粒剂、胶囊剂等成型工艺的辅料是常用的助剂，例如淀粉、明胶、阿拉伯胶、聚乙二醇等，此外还有表面活性剂、润滑剂、崩解剂、防腐剂、矫味剂、色素等。
3.有益效果
本发明的优点是：
(1)所得组合物组成简洁，配方合理，主要活性成分明确。从两种天然植物茯苓、和生姜中提取的活性成分，按重量配比组成PG组合物。
(2)药效显著、安全可靠。动物试验结果表明该组合物高、低剂量组均能显著减少小鼠的绝对不动时间，表明该组合物具有明显的抗抑郁活性。
(3)工艺简单，易于工业化生产。从茯苓和生姜中提取活性成分的方法简单、而且制备成组合物时只需按重量配比将组分混合后即可获得，所以制备工艺简单易行，有利于工业上规模化生产。
四、具体实施方式：
实施例1.治疗抑郁症的药物组合物
一种治疗抑郁症的药物组合物，由茯苓多糖3.5-14g、姜油0.2-3.5g所组成；
实施例2药物组合物的制备方法，其步骤为：
(1)取干燥茯苓菌核，用10倍体积的水提取三次，合并提取液，浓缩后加95％乙醇至乙醇浓度为80％，所得沉淀即为茯苓多糖，得率为80.1％；
(2)取干燥生姜，用常规水蒸气提取三次，得率为1.0％。
(3)取茯苓多糖10g和姜油1g，用β-环糊精包合姜油后，混合即得组合物PG。在上述组合物PG中加入适量的淀粉，制成片剂。
实施例3 组合物对绝望模型小鼠行为的影响
动物模型：小鼠强迫游泳实验和小鼠悬尾游泳实验
动物：雄性昆明种小鼠，体重28±2g，随机分组。
灌胃给药15天后，进行行为实验，测定小鼠强迫游泳和悬尾实验中的绝对不动时间；
组合物组份对小鼠强迫游泳实验和悬尾实验的作用结果见表1。抑郁症的一个主要症状是动机行为的减少，强迫游泳实验和悬尾实验中的挣扎是动物的动机行为，而绝对不动则反映了实验中动物消极的无动机状态。大多数抗抑郁药物能增加受试动物的动机行为，减少强迫游泳实验和悬尾实验中的绝对不动时间。阳性药氟西汀高低两个剂量均能显著降低强迫游泳和悬尾实验中小鼠的绝对不动时间。组合物高剂量组均能显著减少两个实验中小鼠的绝对不动时间。结果表明组合物具有明显的抗抑郁活性。
