Description
技术领域
本发明涉及医药或食品技术领域,更具体的说是涉及一种改善炎症性肠病的提取物及其应用。
背景技术
炎症性肠病(inflammation bowel disease,IBD)是一种病因未明的肠道炎症性疾病,和普通肠炎有较大区别。普通肠炎一般是急性的,进行抗感染治疗后可以治愈。而IBD病程迁延,反复发作,迁延不愈,严重的可能致残甚至危及生命,有“不死癌症”、“绿色癌症”之称。IBD发病与包括环境压力和基因缺陷在内的多种因素相关,其中免疫异常在CD早期发病中起到关键作用。在健康肠道稳态中,T淋巴细胞向肠黏膜的迁移是正常受控的。但在病理状态下,由于肠上皮屏障的破坏,微生物或抗原侵入肠壁,导致异常的T淋巴细胞迁徙,进一步释放促炎细胞因子,导致肠道炎症。失控的T淋巴细胞迁徙导致淋巴细胞在肠道中蓄积,促使炎症级联放大过程,肠道持续炎症,导致IBD疾病慢性化和肠道损伤。随着疾病的进展,后续肠道发生纤维化病变、狭窄和梗阻。IBD主要包括溃疡性结肠炎(ulcerativecolitis,UC)和克罗恩病(crohn disease,CD),两者最大的区别是:UC的炎症只局限于大肠,而CD的炎症可以发生于全消化道从口腔到肛门部。近年来该病的发病率和患病率逐年增加,临床难以治愈、易于复发,成为国内外消化疾病领域的常见病及疑难病严重影响患者生活质量。大部分IBD患者需终生治疗,而临床主要治疗药物如糖皮质激素、氨基水杨酸、免疫抑制剂和抗肿瘤坏死因子抗体副作用较多,多数患者不能长期坚持治疗,导致疾病复发和进展。因此,开发安全有效的IBD改善剂具有重要意义。
苦苣菜为菊科苦苣菜属一年生或二年生草本。在民间常作为野菜食用。《中国植物志》和《全国中草药汇编》记载,苦苣菜全草入药,清热解毒,凉血止血。用于肠炎,痢疾,急性黄疸型传染性肝炎,阑尾炎,乳腺炎,口腔炎,咽炎,扁桃体炎,吐血,衄血,咯血,便血,崩漏;外用治痈疮肿毒,中耳炎功效。现代药理研究表明苦苣菜具有抗氧化、抗肿瘤等作用,然而关于苦苣菜改善IBD的研究尚未见报道。
发明内容
有鉴于此,本发明提供一种以苦苣菜和山药为原料更有效的用于改善IBD的天然植物提取物。
为了达到上述目的,本发明采用如下技术方案:
一种改善炎症性肠病的提取物,所述提取物为苦苣菜提取物,制备方法为:以苦苣菜为原料,C1~C5低级醇水溶液为溶剂进行提取,减压提取,然后过滤、浓缩、干燥,获得苦苣菜提取物。
优选的,所述提取物还包括山药提取物,将山药提取物和苦苣菜提取物按照(1~3):(3~1)的质量比进行复配;
所述山药提取物的制备方法为:以山药为原料,水为溶剂进行减压提取,然后过滤、浓缩、干燥,获得山药提取物。
优选的,山药提取物和苦苣菜提取物按照1:1的质量比进行复配。
优选的,所述山药提取物和苦苣菜提取物制备时料液比g·mL-1均为(1:8)-(1:10),减压提取温度均为60-100℃,提取时间为2-4h,浓缩密度均为1.05-1.14,干燥温度均为进口温度120-125℃,出口温度60-70℃。
优选的,所述C1~C5低级醇水溶液为60-70vt.%乙醇。
本发明还公开了上述提取物在制备用于治疗或缓解炎症性肠病的药物中的应用。
优选的,所述炎症性肠病选自溃疡性结肠炎、未确定型结肠炎、克罗恩病、淋巴细胞性结肠炎、显微镜下结肠炎、胶原性结肠炎、自身免疫性肠病、过敏性胃肠病和嗜酸性胃肠病。
优选的,所述药物是以所述提取物为活性成分,单独或与其他药物组方,加入药学上可接受的辅料、辅助性成分或载体制备成药学上可接受的剂型。
优选的,所述剂型为硬胶囊剂、软胶囊剂、散剂、颗粒剂、片剂、丸剂、蜜膏剂、口服液、栓剂、酒剂或注射剂。
优选的,药学上可接受的载体是指药学领域常规的药物载体,例如:稀释剂、赋形剂如水等,填充剂如淀粉、蔗糖等;黏合剂如纤维素衍生物、藻酸盐、明胶及聚乙烯吡咯烷酮;湿润剂如甘油;崩解剂如琼脂、碳酸钙及碳酸氢钠;吸收促进剂如季铵化合物;表面活性剂如十六烷醇;吸附载体如高岭土及皂黏土;润滑剂如滑石粉、硬脂酸钙、硬脂酸镁及聚乙二醇等。另外还可以加入其它药学领域常规的辅剂如甜味剂、香味剂等。
本发明的有益效果为:
山药,中药材名,为薯蓣科植物薯蓣的干燥根茎,治脾虚泄泻,久痢,虚劳咳嗽,消渴,遗精、带下,小便频数。本发明首次发现并提出苦苣菜提取物能够应用于防治炎症性肠病及制备治疗炎症性肠病的药物,相较于传统的氨基水杨酸类、类固醇激素类等药物毒副作用或不良反应小,且发现将苦苣菜和山药进行配伍具有协同增效的作用,可以缓解和治疗炎症性肠病。
具体实施方式
下面将对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
1实验方法
1.1提取物的制备
1.1.1山药提取物的制备
(1)按照料液(水)比1:10(g·mL-1)、60℃减压提取,提取时间2h,经过滤(过滤孔径0.45μm)得到山药提取液;
(2)将步骤(1)中得到的山药提取液进行减压浓缩,浓缩密度为1.14;
(3)将步骤(2)中得到的浓缩液进行喷雾干燥,进口温度120℃,出口温度65℃,获得山药提取物。
1.1.2苦苣菜提取物的制备
苦苣菜提取物的制备方法,包括如下步骤:
(1)选取苦苣菜的地上部分,按照料液(60vt.%乙醇)比1:10(g·mL-1)、60℃减压提取,提取时间2h,经过滤(过滤孔径0.45μm)得到苦苣菜提取液;
(2)将步骤(1)中得到的苦苣菜提取液进行减压浓缩,浓缩密度为1.14;
(3)将步骤(2)中得到的浓缩液进行喷雾干燥,进口温度120℃,出口温度65℃,获得苦苣菜提取物。
1.1.3苦苣菜提取物和山药提取物复合物的制备方法,包括如下步骤:
将根据1.1.1和1.1.2方法制备的山药提取物和苦苣菜提取物按照一定比例进行复配,获得山药和苦苣菜复合提取物(SK),备用。
1.2实验分组和IBD造模
TNBS它是一个小分子,本身不具有抗原性,但与宿主蛋白结合后会引起免疫反应,因此属于半抗原。TNBS处理小鼠可建立模拟临床克罗恩氏病(CD)的临床前模型,其产生的免疫反应是Th1介导的,特征在于CD4 +T细胞、嗜中性粒细胞和巨噬细胞的浸润。形成横向进展的炎症,导致透壁结肠炎。本研究选择BABL/c小鼠84只,18~22g,雌雄各半,随机分为正常对照组、模型组、山药提取物组、苦苣菜提取物组、三种不同比例的SK组,每组12只。正常对照组不造模,正常饲养。模型组、山药提取物组、苦苣菜提取物组和不同比例的SK组利用TNBS诱导建立小鼠IBD模型。小鼠于实验前剃毛,皮肤外涂TNBS 3.75mg,分别于外涂TNBS后的第7天、第14天、第21天直肠给予TNBS 0.75、1.5、2.25mg。药物干预与造模同时进行。山药提取物组、苦苣菜提取物组、三种不同比例的SK组每天给药1次,每次0.1g,正常对照组和模型组给予等量生理盐水,每日1次,连续灌胃给药28d。每日记录小鼠体质量和死亡情况。
1.3指标检测
实验结束时处死小鼠,取血。取结直肠称质量,测量长度和厚度。距肛门5、10、15cm分别取结直肠组织进行组织炎症细胞因子含量检测。取肠道组织,经液氮研磨后,加入1mLTrizol regent提取肠道总RNA,酶标仪检测RNA浓度及纯度。将1μg RNA用于反转录得到cDNA,-20℃保存,用于后续Rt-qPCR,使用β-actin作为内参基因。利用Rt-qPCR检测IL-1β、TNF-a和IL-10。采用△Ct法测定不同细胞因子的相对表达量。
1.4协同作用
实验通过计算相互作用指数γ评价复配能力。复配物的理论IC50add值计算公式为IC50add=IC50A/(K1+Q×K2)
式中:Q为A(山药提取物)、B(苦苣菜提取物)两种提取物单独作用时的效价比,即Q=IC50A/IC50B;K1、K2分别为山药提取物、苦苣菜提取物在复配体系中所占的比例,K2=1-K1。
通过上述实验能够算出复合物实际IC50mix值。得到山药提取物和苦苣菜提取物复配后理论上所需的浓度IC50add值。将二者进行比较,若IC50mix<IC50add,即可证明两种样品复配之后具有协同作用。复配物之间协同作用的强弱用γ值来表示,计算公式为γ=IC50Amix/IC50A+IC50Bmix/IC50B。
式中:IC50Amix、IC50Bmix分别为复配体系中山药提取物和苦苣菜提取物各自的IC50值;IC50A、IC50B分别为山药提取物和苦苣菜提取物两种提取物单独作用时的IC50值。若γ=1,表示相互作用为相加;若γ<1,表示二者之间存在协同,γ值越低,协同作用越强;若γ>1,表示相互作用为拮抗作用。
2实验结果
2.1SK对TNBS诱导的IBD小鼠存活率的影响
结果见表1。正常对照小鼠实验过程中未出现死亡,存活率为100%;模型组小鼠,28d动物存活率为40%,经X2检验,与正常对照组比较具有显著性差异;山药提取物组、苦苣菜提取物组和SK组28d动物存活率分别为58%、75%和83%,与模型组比较差异具有统计学意义。提示SK能够更显著提高TNBS诱导的IBD模型小鼠的存活率。
表1SK提取物对TNBS诱导的IBD小鼠存活率的影响
2.2SK对TNBS诱导的慢性结肠炎小鼠结肠质量长度比值的影响
结果见表2。TNBS诱导的慢性结肠炎小鼠结肠重量/长度的比值升高,与正常对照组比较有显著性差异。山药提取物组、苦苣菜提取物组和SK组均能显著降低模型组小鼠升高的结肠重量/长度比值。提示SK能够更显著的降低TNBS诱导的IBD模型小鼠结直肠炎症水肿。
表2SK提取物对小鼠结肠重量/长度比值的影响
2.3SK对模型动物结肠组织炎症因子和CD4 +T的影响
如表3所示,模型组小鼠结肠组织中促炎因子含量均显著升高,抗炎因子降低。与正常对照组比较具有显著性差异;与模型组相比,山药提取物、苦苣菜提取物和SK(山药:苦苣菜)能显著降低小鼠促炎因子的升高,抗炎因子的降低和CD4 +T的升高。提示SK能显著抑制小鼠促炎因子的升高,抗炎因子的降低和CD4 +T的升高。
表3SK对炎症因子和CD4 +T的影响
2.4SK对CD4 +T的协同作用
由表4可知,理论IC50mix值都比实验IC50add值小,各组合的γ值也均小于1。即证明山药提取物与苦苣菜提取物按不同比例重新组合后降低CD4 +T含量的效果比单独作用时强,具有协同效果。
表4SK协同降低CD4 +T含量
结论:山药提取物、苦苣菜提取物、SK组均具有改善炎症性肠炎的功能,山药提取物和苦苣菜提取物能够协同改善炎症性肠炎。
本说明书中各个实施例采用递进的方式描述,每个实施例重点说明的都是与其他实施例的不同之处,各个实施例之间相同相似部分互相参见即可。
对所公开的实施例的上述说明,使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的,本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下,在其它实施例中实现。因此,本发明将不会被限制于本文所示的这些实施例,而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
