热淋清浸膏及其制备方法和用途
技术领域:
本发明涉及中药领域, 具体而言, 本发明涉及热淋清浸膏及其制备方法 以及这种浸膏作为药物的用途。
背景技术:
(Polygonum capi ta turn Buch.― Ham. ex D. Don )是雾科雾属植 物, 为多年生草本, 别名四季红、 石莽草、 石辣蓼、 水绣球、 红花地丁、 满 地红等。 在中国贵州、 云南、 广西、 四川、 西藏、 湖北、 湖南和江西等地区 均有分布, 主要生长在山坡、 山谷及富含煤层的沙页岩地带。 全草具有清热 解毒、 散瘀、 利尿通淋之功效。 据 1963年《广西中药志》第二册记载, 头花 蓼主要用于治疗风湿痛; 1977年《中药大辞典》上册记载, 头花蓼主要用于 治疗痢疾、 肾炎、 膀胱炎和尿路结石等。 民间一般将头花蓼用水煎服, 治疗 效果比较明显, 但是服用不方便。 中国专利申请公开说明书 CN1 054899A中公 开了一种泌感灵冲剂、 糖浆生产工艺, 该方法是将中草药头花蓼经煎煮后过 滤, 减压浓缩成膏状, 再用乙醇提取 2 - 3次, 真空浓缩制成浸膏, 再将浸膏 分别制成糖浆或冲剂。 该生产工艺包括煎煮、 浓缩、 提取、 再浓缩等步骤, 工艺复杂, 而且, 该方法得到的泌感灵冲剂的药效学效果有待提高。 我们贵 州威门药业有限公司长期致力于中草药头花蓼的开发利用研究,我们将头花 雾加水煎煮两次后过滤浓缩制成热淋清颗粒, 该制剂公开在中华人民共和国 卫生部药典委员会 1998年编的中华人民共和国卫生部《药品标准- -中药成 方制剂》 (第十七册)中, 但是, 随着研究的不断深入, 本发明人发现, 1998 年编的中华人民共和国卫生部《药品标准- -中药成方制剂》 (第十七册)中 的热淋清颗粒的制备工艺中, 其提取和精制方法上存在缺陷, 按照该工艺, 将 1 000克头花蓼煎煮, 不可能制成 400克浸膏颗粒, 即便是加入适量蔗糖粉, 制成 800克热淋清颗粒, 这种热淋清颗粒制剂由于活性成分含量低, 其药理 学效果差。 本发明人通过对中草药头花蓼进行长期开发研究, 并结合药理学 试验验证发现, 通过改进提取和精制工艺, 得到的头花蓼提取物的药理活性 明显提高, 并发现这种头花蓼提取物具有新的疗效。
发明内容:
因此, 本发明的目的是提供了一种热淋清浸膏;
本发明的另一发明目的是提供了一种制备热淋清浸膏的方法;
本发明的另一发明目的是提供了热淋清浸膏用于制备抗菌、 抗炎、 镇痛 和利尿的药物的用途;
本发明的另一发明目的是提供了含有本发明热淋清浸膏的药物组合物。 本发明的目的是通过下列方法实现的。
本发明人分别对头花蓼的不同药用部位进行了研究, 对头花蓼全草、 头 花蓼地上部分、 叶、 种子、 茎和根部分别进行了提取和活性研究, 本发明人 发现, 头花蓼的叶、 种子、 茎和根部分的药学活性是有差别的, 抗炎活性以 叶提取物为最佳; 抗菌活性的强弱顺序是种子〉叶〉茎〉根。 本发明人从这一 发现中得到启示, 用头花蓼的地上部分代替传统使用的头花蓼全草进行提 取, 这样既保持和提高了提取浸膏的药学活性, 又避免使用头花蓼的根部。 由于头花蓼是本草植物, 不使用其根部, 可以避免在釆集头花蓼时将其根部 拔起, 这样, 头花蓼可以再生, 既保护了植物资源, 有保护了土地植被, 这 对保护资源和环境都有重要意义。
具体而言, 本发明提供了一种热淋清浸膏, 其特征在于由头花蓼全草的 鲜品或干品用水分 1-3次煎煮, 每次 1-2小时, 合并煎煮液, 过滤浓缩至 85 时的相对密度为 1. 05 ~ 1. 25、 优选 1. 1 ~ 1. 2 , 更优选 1. 2时, 得到浸膏, 然后经喷雾干燥, 得到浸膏粉。
本发明的另一优选技术方案是在于喷雾干燥前加入辅料淀粉,优选加入 重量比 5% 的辅料淀粉。 本发明的另一优选技术方案是其中头花蓼选用其地上部分, 其中头花蓼 地上部分是叶、 花和茎。
本发明的药物组合物可以制成片剂、 颗粒剂、 丸剂、 胶嚢剂、 喷雾剂、 注射剂、 洗剂、 栓剂、 滴丸剂、 合剂、 擦剂、 贴剂、 膜剂、 纸型剂、 混悬剂、 酊剂、 干糖浆剂、 泡腾片、 硬膏剂、 软膏剂、 糖浆剂、 乳剂、 散剂、 緩释、 控释制剂及靶向制剂, 优选制成颗粒剂。
具体实施方式:
一、 提取物制备
本发明的热淋清浸膏是通过下列方法得到的:
根据国家食品药品监督管理局的有关规定, 以制成品量 l OOOg为单位来 计算头花蓼药材的用量。 根据原标准中头花蓼药材的用量, 最终确定制成热 淋清颗粒(含蔗糖) l OOOg , 热淋清颗粒(无糖型) 500g所需头花蓼药材量为 1250g。 热淋清颗粒原质量标准没有明确规定干燥方法。 故对干燥方法进行 了研究确定。
热淋清浸膏原主要釆用烘箱干燥的方式,主要有常温干燥和减压干燥。 其中,釆用常温干燥及减压干燥的方法, 不但耗时长,浸膏干燥后为块状物, 还需进一步的粉碎, 此外, 粉碎后浸膏粉易吸潮, 变质, 不利于保存。 后釆 用的喷雾干燥, 生产工艺简便, 可实现头花蓼提取物的瞬间干燥, 其均匀性 及含水量均较好, 干燥所得的浸膏粉稳定性好, 同时, 确保制成品热淋清颗 粒的质量。
实施例 1 : 常温干燥(编号: W-1)
取头花蓼 220Kg , 加水煎煮二次, 每次 1. 5小时, 合并煎液, 滤过, 滤液 浓缩至相对密度为 1. 20 ± 0. 05 (85 °C)的清膏, 滤过, 常温干燥。
实施例 2 : 减压干燥(编号: W-2)
取头花蓼 220Kg , 加水煎煮二次, 每次 1. 5小时, 合并煎液, 滤过, 滤液 浓缩至相对密度为 1.20 ± 0.05 (85°C)的清膏, 滤过, 减压干燥。 实施例 3: 喷雾干燥(编号: W-3)
取头花蓼 220Kg, 加水煎煮二次, 每次 1.5小时, 合并煎液, 滤过, 滤液 浓缩至相对密度为 1.10 ± 0.05 (85°C)的清膏, 滤过, 喷雾干燥。
实施例 4: 浸膏加 5%的可溶性淀粉喷雾干燥(编号: W-4)
取头花蓼 220Kg, 加水煎煮二次, 每次 1.5小时, 合并煎液, 滤过, 滤液 浓缩至相对密度为 1.20 ± 0.05 (85°C)的清膏, 滤过, 加重量比 5%可溶性淀 粉混勾, 喷雾干燥。
实施例 5: 浸膏加 10%的可溶性淀粉喷雾干燥(编号: W-5)
取头花蓼 220Kg, 加水煎煮二次, 每次 1.5小时, 合并煎液, 滤过, 滤液 浓缩至相对密度为 1.10 ± 0.05 (85°C)的清膏, 滤过, 加重量比 10%可溶性淀 粉混勾, 喷雾干燥。
实施例 6: 浸膏加 5%的糊精喷雾干燥(编号: W-6)
取头花蓼 220Kg, 加水煎煮二次, 每次 1.5小时, 合并煎液, 滤过, 滤液 浓缩至相对密度为 1.10士 0.05 (85°C)的清膏, 滤过, 加重量比 5%糊精混匀, 喷雾干燥。
不同干燥方式所得浸膏粉物性比较结果表
Figure imgf000005_0001
不同干燥方式所得浸膏粉稳定性比较结果表
Figure imgf000006_0001
可以看出, 热淋清浸膏釆用直接喷雾干燥或先加 5%的可溶性淀粉与 浸膏混合后再喷雾干燥两种方式均可, 但釆用加入淀粉较不加淀粉所得 的浸膏粉性质更加稳定, 其制成品的含量也较方法 1所得浸膏制成品的含 量为高。
喷雾干燥较传统蒸发操作与减压干燥工艺相比耗时短、 干燥质量好、 省去蒸发、 粉碎等工序。 大大提高了生产效率, 同时又能相对提高干燥 成品热淋清浸膏的质量, 因喷雾干燥所得的热淋清浸膏粉为粉末状, 较 传统干燥成品的流动性好, 含水量小, 质地均勾, 溶解性好。 喷雾干燥 具传热快, 水分蒸发迅速, 瞬间干燥的特点, 所得的热淋清浸膏质量好, 质地松脆, 溶解性能也好, 改善了成品制剂热淋清颗粒的溶出速率。
以上试验结果也表明: 釆用喷雾干燥所得的样品收率较高, 水份含 量均勾, 浸膏粉溶化性好, 总黄酮及没食子酸含量较高, 稳定性好, 同 时, 釆用喷雾干燥还可大大缩短干燥时间, 节约成本。 故确定釆用喷雾 干燥。 其中, 釆用常规喷雾干燥, 与釆用浸膏加 5%可溶性淀粉喷雾所得 的浸膏就有效成分的含量及稳定性而言, 以后者更好。

注: "*"表示与生理盐水组比较 p< 0. 05 , 表示与生理盐水组比较 p< 0. 01 由表 3-1可见: 热淋清浸膏粉 w-3中剂量 17. 4g原生药 /kg及 w-4中剂 量 17. 2g原生药 /kg , 在用药后 0. 5小时即呈现出利尿作用, 与同时间点生理 盐水组比较有显著性差异(p< 0. 01)。
用药后 1. 0小时低, 中剂量组同样表现出差异(与生理盐水比较), 排泄尿 量显著性超过生理盐水小组(分别 p< 0. 05, P< 0. 01)。 阳性药也显示出明显的 利尿作用。 但热淋清浸膏粉(w-3) 34. 8 g原生药 /kg剂量组及热淋清浸膏粉 (w-4) 34. 3g原生药 /kg剂量组在本次试验中没有出现明显药效作用,即未呈量 效关系, 推测是否由于过多的药粉吸收了灌服水份所致。
从给药后 0. 5、 1. 0小时的尿量排泄百分率(%) (表 3-2)来看, 阳性药速尿 的利尿强度最大。 0. 5小时已排出 24. 0%的尿量, 热淋清浸膏粉 w-3的 1 7. 4g原 生药 /kg剂量组及 w-4的 17. 2g原生药 /kg剂量组也呈现较强的利尿作用, 从表 中可看出中药热淋清浸膏粉的利尿起效时间不如西药速尿, 相对要延后些。

(5)实验数据处理
热淋清浸膏粉与对照药氟哌酸胶嚢对金黄色葡萄球菌 MSSA43、 大肠 埃希菌 994、 变形杆菌 993、 淋球菌 14感染小鼠的体内保护作用的半数有 效剂量 ED5。及其 95%可信限, 均按 Bl i s s法运用中国医学科学院编制的程序 软件, 使用计算机进行计算和统计学处理。 结果见表 5-6 ~ 5-10。

体内保护试验结果表明, 热淋清浸膏粉 w-3口服给药, 对小鼠由金黄 色葡萄球菌 MSSA43、 大肠埃希菌 9914、 变形杆菌 993和淋球菌 14所致小鼠 全身感染的半数有效剂量 ED5。值分别为 11.85g原生药 /kg、 37.84g原生药 /kg , 22. 08g原生药 /kg、 1 0. 14g原生药 /kg ; 热淋清浸膏粉 w-4口服给药, 对小鼠由金黄色葡萄球菌 MSSA4 3、 大肠埃希菌 9914、 变形杆菌 993和淋球 菌 14所致小鼠全身感染的半数有效剂量 ED5。值分别为 1 1. 82g原生药 /kg、 37. 87g原生药 /kg、 20. 95 g原生药 /kg、 9. 31 g原生药 /kg。 结果表明: 热 淋清浸膏粉 w-3、 w-4对所试菌株具有一定的体内保护作用。
综上所述: 经体外抗菌试验结果证明: 热淋清浸膏粉呈现出一定的 体外抗菌活力, 尤其是对临床分离淋球菌显示出较强的抗菌活力, 其次 对金黄色葡萄球菌、 表皮葡萄球菌、 大肠埃希菌、 痢疾杆菌、 变形杆菌 和肺炎克雷伯菌也呈现出抗菌活力。 但对白色念珠菌的抗菌活力较弱。 对浅表毛癣菌如石膏样孢子菌、 石膏样癣菌也呈现一定的抗菌活力, 其 次对于厌氧菌中的脆弱拟杆菌, 消化球菌、 消化链球菌和痤疮丙酸杆菌、 颗粒丙酸杆菌等均具有一定的抗菌作用。 体内试验结果也表明, 热淋清 浸膏粉对淋球菌、 金黄色葡萄球菌、 变形杆菌、 大肠埃希菌感染小鼠具 有一定的保护作用, 其半数致死剂量 ED5。分别为 1 0. 14、 1 1. 85、 22. 08、 37. 84原生药 g/kg , w-4半数致死剂量 ED5。分别为 9. 31、 1 1. 82、 20. 95、 37. 87 原生药 g/kg。 因此, 用热淋清浸膏粉制成的热淋清颗粒具有清热解毒, 利尿通淋的作用。 用于湿热蕴结, 小便黄赤、 淋漓涩痛之症, 尿路感染, 肾孟肾炎及上述证候者。
