Description
技术领域
本发明涉及中药技术领域,特别是涉及一种具有舒筋活络,消瘀散结,消肿止痛作用的中药按摩精油及其制备方法。
背景技术
随着人们生活水平越来越高,对养生保健的重视程度也是与日俱增。为了缓解高工作强度给身体带来的不适,通过按摩来解决身体酸痛、血脉郁结不通等症状越来越受到人们欢迎,但按摩中选用具有保健作用的辅助产品往往具有刺激性,人们使用后经常会出现红肿、瘙痒、疼痛等症状,这是因为辅助产品中往往含有多肽、多糖等物质,皮肤接触后往往会产生排异反应,发生上述症状。同时,在临床使用中,为了缓解患者身体酸痛、血脉郁结不通的症状,在选用按摩产品时一般仅仅针对相关症状的产品,而不会考虑患者整体状况,症状只是暂时缓解,不能达到长期效果。
发明内容
中药按摩精油一般由一种或多种中药,经过一定制备工艺制成的对人体起保健作用的产品,是植物挥发性芳香物质以及植物免疫与修护系统的精华。精油的优势主要体现在高渗透性、代谢快、不滞留、毒性小等特点,达到开窍化浊、活血化瘀的治疗目的。在使用精油时,与中医经络理论相结合,配合推拿、按摩,将精油直接作用于特定穴位上,可能有更好的疗效。中医认为,经络系统是气血运行的主要通道,而芳香精油大多具有芳香走窜、疏理气机的作用,可以辅助经络系统运行气血、营养全身、抵御外邪等。
目前按摩精油一般由从中药中提取的挥发油作为有效成分。目前中药挥发油的提取方法包括水蒸气蒸馏法和超临界CO2流体萃取法等提取方法,水蒸气蒸馏法具有设备简单和操作方便的优点。超临界CO2流体萃取技术是利用超临界流体具有液体的萃取能力(密度与液体接近),而具有气体的粘度(粘度与气体接近),在CO2临界点附近对压力和温度极其敏感的物理特性,通过改变温度或压力而改变溶质在溶剂中的溶解度实现其分离,具有操作温度低、时间短、绿色环保无污染、萃取效率高等优点。
为解决上述现有技术的不足,本发明通过选用具有固表益气的黄芪、活血调经的益母草、益气补中的甘草来提升患者身体整体素质;通过采用水蒸气蒸馏法和超临界CO2流体萃取法在高效富集有效成分的前提下,避免了传统工艺提取物中包含的多肽、多糖等成分,从而避免了皮肤过敏情况的发生。
一种具有舒筋活络,消瘀散结,消肿止痛作用的中药按摩精油,由如下重量份的原料药制成:鸡血藤10-50、桑枝10-50、当归5-20、川芎4-12、海风藤10-50、络石藤10-50、伸筋草10-50、丝瓜络5-20、地锦草3-20、益母草3-20、黄芪10-50、甘草2-20。
其原料药重量份优选为:鸡血藤20-40、桑枝20-40、当归12-20、川芎6-10、海风藤20-40、络石藤20-40、伸筋草20-40、丝瓜络12-20、地锦草10-20、益母草10-20、黄芪20-40、甘草3-20。
其原料药重量份进一步优选为:鸡血藤30、桑枝30、当归15、川芎9、海风藤30、络石藤30、伸筋草30、丝瓜络15、地锦草10、益母草10、黄芪30、甘草5。
中药按摩精油的制备方法,具体步骤如下:
(1)原料药粉碎至10目;
(2)鸡血藤、桑枝、丝瓜络、地锦草、益母草和黄芪放入超临界提取罐,萃取温度60℃,在压力40MPa条件下提取4.5h,CO2流速40L/h,得到油状提取物1;
(3)当归、川芎、海风藤、络石藤、伸筋草和甘草放入提取容器中,根据1:9的比例加入纯净水,浸泡2h,连接挥发油提取装置,加热回流3h,冷却提取液,用石油醚萃取提取液,经干燥后得到油状提取物2。
(4)将油状提取物1和油状提取物2混合即得。
一种中药按摩精油的制备方法,具体步骤如下:
(1)原料药粉碎至10目;
(2)鸡血藤30g、桑枝30g、丝瓜络15g、地锦草10g、益母草10g和黄芪30g放入超临界提取罐,萃取温度60℃,在压力40MPa条件下提取4.5h,CO2流速40L/h,得到4.73g油状提取物1;
(3)当归15g、川芎9g、海风藤30g、络石藤30g、伸筋草30g和甘草5g放入提取容器中,根据1:9的比例加入纯净水,浸泡2h,连接挥发油提取装置,加热回流3h,冷却提取液,用石油醚萃取提取液,经干燥后得到2.25g油状提取物2;
(4)将油状提取物1和油状提取物2混合即得。
本发明的中药按摩精油及其制备方法具有如下有益效果:
1.选用水蒸气蒸馏和超临界CO2萃取的提取方法,将原料药含有的多肽、多糖等容易导致过敏的成分去除,保留了具有舒筋活络,消瘀散结,消肿止痛作用的有效成分,避免临床中过敏现象的产生。
2.针对临床患者常伴有阳气虚弱、中气不足的情况。本发明中选用了益母草、黄芪和甘草,在保证舒筋活络,消瘀散结,消肿止痛功效的基础上增强益气升阳,固表止汗作用上取得了突出的疗效。
3.对不同工艺进行优化,原料药的提取方法经过大量工艺条件筛选,选用方差分析等数理统计方法确定最适合工艺条件,从而保证产品技术效果,有效提高组合物整体疗效。

1.2数据分析和统计
应用SPSS17.0统计软件对刺激反应分值和过敏反应分值进行统计分析,比较采用LSD检验,P<0.05为差异有统计学意义。
1.3二甲苯致小鼠耳廓肿胀试验
取洁净小鼠60,随机分成6组,每组10只,分别标记为精油1组、精油2组、精油3组、精油4组、青鹏软膏组、生理盐水组。分别于动物右耳正反两面共涂相应药物0.5ml(相当于原料药20g/耳)、青鹏软膏组涂青鹏软膏(0.06g/耳),膏剂给药厚度2mm,生理盐水组涂0.9%氯化钠注射液0.5ml;10min给药1次,定时定量给药,连续用药1h,共给药6次。用药后用0.9%氯化钠注射液擦净右耳后再用干药棉擦干。10min后涂二甲苯0.04ml/右耳,于致炎后10min、2h各组再次分别涂以相应量药物1次。涂二甲苯4h后处死小鼠,处死前取用0.9%氯化钠注射液擦净右耳后再用干药棉擦干。小鼠脱颈椎处死后,剪下双耳,对齐,用8mm打孔器取下圆型耳片,迅速用分析天平称量双耳,计算肿胀度(肿胀度=右耳-左耳)。
结果见表2。从表2可以看出加入益母草、黄芪、甘草后提取得到的精油1-3组对小鼠耳廓肿胀效果明显要好于没有添加上述三味药材提取得到精油4组,其中精油1组与精油4组有显著性差异(P<0.05)。选用鸡血藤、桑枝、丝瓜络、地锦草、益母草和黄芪采用超临界提取方法,当归、川芎、海风藤、络石藤、伸筋草和甘草采用水蒸气蒸馏提取方法,合并得到的精油1组对小鼠耳廓肿胀效果要好于其他制备方法得到的精油2、精油3组。与生理盐水组相比,精油1-3都能显著减轻小鼠耳廓肿胀(P<0.01),精油4组明显减轻小鼠耳廓肿胀(P<0.05),均有明显抗炎作用。

结果见表5。从表5看出,对皮肤的刺激程度:空白组=精油1组<精油2组<精油3组<精油4组;精油1组对于完整皮肤和破损皮肤都没有刺激性,根据评价标准属于无明显刺激性;精油2组、精油3组对完整皮肤无明显刺激性,对破损皮肤有一定刺激性,在末次给药后1h后受试动物出现轻度红斑,48h后红斑消失,与空白组和精油1组比较,差异有统计学意义(P<0.05),根据评价标准属于无明显刺激性;精油4组对于完整皮肤和破损皮肤都有一定刺激性,在末次给药后1h后受试动物出现中度红斑和轻度水肿,72h后症状消失,与空白组和精油1组比较,差异有统计学意义(P<0.05),根据评价标准属于轻度刺激性。试验过程中未出现受试动物饮食行为异常和死亡。

注:与空白组比较,xP<0.05,与精油1组比较,yP<0.05。
根据表3、表4可以看出加入益母草、黄芪、甘草后提取得到的精油1-3组对皮肤急性与连续刺激性效果要好于没有添加上述三味药材提取得到精油4组(P<0.05)。选用鸡血藤、桑枝、丝瓜络、地锦草、益母草和黄芪采用超临界提取方法,当归、川芎、海风藤、络石藤、伸筋草和甘草采用水蒸气蒸馏提取方法,合并得到精油1组对皮肤急性与连续刺激性效果要好于其他制备方法得到的精油2、精油3组。
2.5.2皮肤过敏试验结果
从表6看出,精油1组与空白组相同,对皮肤无致敏性,精油2、3组虽然有致敏数,但与空白组相比差异均无统计学意义(P>0.05);与阳性对照组比较,精油1-4组差异均有统计学意义(P<0.01)。根据致敏性评价标准,精油1-3组表现为对皮肤无致敏性,精油4组表现为对皮肤有轻度致敏性。

注:与空白组比较,xP<0.05,与精油1组比较,yP<0.05,与阳性组比较,zP<0.01。
根据表6可以看出加入益母草、黄芪、甘草后提取得到的精油1-3组过敏反应强度要好于没有添加上述三味药材提取得到精油4组过敏反应强度(P<0.05)。选用鸡血藤、桑枝、丝瓜络、地锦草、益母草和黄芪采用超临界提取方法,当归、川芎、海风藤、络石藤、伸筋草和甘草采用水蒸气蒸馏提取方法,合并得到精油1组致敏率好于其他制备方法得到的精油2、精油3组,更好于不包括益母草、黄芪、甘草提取得到的精油4组(P<0.05)。
3.部分工艺条件筛选
3.1水蒸气蒸馏法工艺筛选
适宜的料液比可有效增加物料与溶剂的接触面积,浸泡时间和提取时间决定有效成分是否提取完全。以料液比、浸泡时间、提取时间设计三因素三水平正交试验,实验分为九组,以挥发油的收率为考察指标。实验方案及结果如表7所示。
表7水蒸汽蒸馏法中料液比、浸泡时间、提取时间工艺筛选
组别 | 料液比 | 浸泡时间(h) | 提取时间(h) | 重量(g) | 收率(%) |
1 | 1:6 | 2 | 3 | 1.04 | 0.877 |
2 | 1:6 | 4 | 5 | 1.46 | 1.234 |
3 | 1:6 | 6 | 7 | 1.26 | 1.067 |
4 | 1:9 | 2 | 3 | 2.08 | 1.896 |
5 | 1:9 | 4 | 5 | 1.96 | 1.653 |
6 | 1:9 | 6 | 7 | 1.81 | 1.522 |
7 | 1:12 | 2 | 3 | 1.78 | 1.507 |
8 | 1:12 | 4 | 5 | 1.42 | 1.194 |
9 | 1:12 | 6 | 7 | 1.23 | 1.035 |
K1 | 0.328 | 0.413 | 0.352 | ||
K2 | 0.498 | 0.407 | 0.411 | ||
K3 | 0.385 | 0.378 | 0.409 | ||
R1 | 0.153 | 0.012 | 0.054 |
由表7可知,R1极值料液比>提取时间>浸泡时间(0.153>0.054>0.012),即浸泡时间对实验的影响最小,料液比对实验的影响最大。水蒸汽蒸馏法确定最佳提取条件为:料液比1:9,浸泡时间2h,提取时间3h。
3.2超临界CO2工艺筛选
考察萃取温度、萃取压力和萃取时间三个因素,CO2流量为40L/h。萃取后收集挥发油,称重并计算收率。
在一定的超临界压力下,升高温度可以增加被萃取物的挥发性,提高萃取率。当温度升高到某一值以上,由于超临界流体的密度降低,溶解能力也随之下降,导致萃取量减少。由表7可知在压力为40MPa、提取时间为4.5h时,当温度为60℃为最适提取温度。
表8超临界中温度、提取压力、萃取时间工艺筛选
由表8可以看出,R2值萃取压力>萃取温度>萃取时间(0.112>0.053>0.051),即萃取压力对萃取率影响最大,萃取时间对萃取率影响最小。超临界CO2流体萃取的最佳提取条件为:温度60℃,压力40MPa,萃取时间4.5h。
以上是对本发明原料药提取部分工艺条件筛选的试验,本发明所付出的劳动不限于上述试验,由以上试验可以看出本发明药物组合物经过发明人不断思考、验证的过程才得出最佳的产品。
