管花肉苁蓉提取物在制备药剂中的 用 技术领域
本发明涉及一种植物提取物的应用, 特别涉及管花肉苁蓉提取物的新用途。
背景技术
随着人们生活水平提高, 社会上各年龄组的女性越来越关注皮肤健康, 皮肤细嫩、 白 壁无瑕是女性永运的追求和向往。 肉苁蓉是著名补肾中药, 具有益精气、 抗衰老的作用, 在我国作为药食两用中药己有二千余年的历史。
日本学者近年来发现苯乙醇甙类作为植物的活性成分,离体培养实验证实苯乙醇甙类 促进 M细胞活动, 形成胶元纤维网。 (Tanimoto S et al l. Yakugaku Zasshi 2006 Mar. 126 (3) : 173-7. Sudo H et al 1 Chem Pharm Bui 1 (Tokyo) . 1999 Sep. 47 (9): 1341-3 related) 近年来科学家发现肉苁蓉的提取物含有苯乙醇甙类,产于新疆南部的管花肉苁蓉是肉 苁蓉种属中的一种, 提取物中苯乙醇甙类含量高于其它种属肉苁蓉。其有望用于皮肤类制 剂, 起到改善皮肤健康, 驻颜美容作用。
中国发明专利(申请号: 200610117216. 1 )记载了一种化妆品组合物, 含有有效量的 管花肉苁蓉提取物, 并指出该化妆品具有抗皱嫩肤作用, 然而皱纹是一个综合的表象, 至 少目前的研究表明皱纹与皮肤细胞水分的流失、 锁水功能的下降、 弹力纤维的减少、 胶原 蛋白的流失等等均有密切的关系。 同样道理, 抗皱嫩肤也是一个综合的表象, 补充水份、 提高皮肤锁水功能、 补充胶原蛋白、 减少自由基等途径均可获得抗皱的目的。 而在该专利 中, 并未具体揭示管花肉苁蓉具体改善了皮肤细胞哪方面的机能。
发明内容
本发明的目的是公开管花肉苁蓉 (Cistanche Tubulosa (Schrenk) Wight ) 提取物的 新用途。
皮肤细胞中的弹力纤维是由弹力蛋白和弹力微纤维所组成,弹力蛋白位于纤维中心部 位,周围为弹力微纤维所包绕,这种组织学上的特点使弹力蛋白分子能够相互滑动,使皮肤 伸展、 回复,富有弹性,这和弹力微纤维的功能是密切相关的。 弹力微纤维的变性、 退化和 减少是形成皱纹的主要原因之一。 而弹力纤维数量的增加, 功能的恢复对于皮肤的抗皱, 受伤或受损皮肤的恢复均具有重要的意义。
发明人针对管花肉苁蓉提取物的功效进行了深入的研究, 在 RT-PCR实验中发现, 管花 肉苁蓉提取物可将 WI-38细胞 (人类二倍体成纤维细胞) 的弹力微纤维的基因表达上调, 在 1%浓度时,弹力微纤维的平均灰度值为对照组的 323. 25%。 据此认为, 管花肉苁蓉提取 物具有促进弹力微纤维生成, 进而促进皮肤弹力纤维生成及皮肤弹力纤维功能恢复的作 用。
就此, 一方面, 本发明公开了管花肉苁蓉提取物或含有管花肉苁蓉提取物的制剂用于 促进皮肤弹力微纤维生成、 恢复皮肤弹力纤维的伸展和回复功能的新用途。
本发明所指的管花肉苁蓉提取物, 富含苯乙醇甙类物质, 优选的是含有质量百分比至 少为 2 %的麦角甾甙 (acteoside)和 4%的松果菊甙(echinacoside), 以提取物的重量为基 准。 麦角 甙和松果菊甙作为提取物中主要的活性成分, 其含量自然是越高越好, 但由于 实际应用时, 考虑到商业成本等因素, 不可能做无限的精提来提高这两种主要活性成分的 含量, 所以只要麦角 甙的重量含量达到 2-80%, 松果菊甙的含量达到 4-80%就可以达到 很好的效果。 最优选的是麦角 甙和松果菊甙的重量含量比大于 2: 1。
上述的管花肉苁蓉提取物富含苯乙醇甙类物质还可含有其它次要成分: 麦角 甙异构 体、 2' -乙酰基麦角 甙和管花肉苁蓉甙 A、 B、 C, 每种的含量均低于 4%, 以提取物的重 量为基准。麦角 甙和松果菊甙的检测方法是根据 2005年版中国药典一部 90页中的含量 测定法 -高效液相色谱法测定得出。
苯乙醇甙类化合物的结构通式为:

d、 将步骤 c所得离心液置于装有 SEPABEADA系列大孔树脂的柱中;
e、 用 10-60%的乙醇或去离子水吸附和洗脱;
f、 收集洗脱液, 经减压、 真空干燥、 粉碎和过筛, 得到富含苯乙醇甙类提取物。 上述制备管花肉苁蓉提取物的方法主要是经过粗提和精提两过程:
粗提是通过水或乙醇浸泡、 煮沸、 过滤、 冷却、 沉淀, 离心后取得离心液为粗制剂。 步骤 b ) 的提取次数优选为 2〜4次, 提取的温度优选为 70〜90°C。

实施例 5 管花肉苁蓉提取物影响 WI-38生长的实验 一: 实验方法与处理
1. 细胞处理
将 WI-38细胞(人类二倍体成纤维细胞)传代接种于两个 6孔板中, 当细胞融合至 60-70% 时, 用管花肉苁蓉提取物进行处理。
处理浓度 (W%)为: 将管花肉苁蓉提取物溶于二甲基丙砜 (Diemet;hy Sulphoxide), 管花肉 苁蓉提取物浓度为 1%和 0.5%;
处理时间为: 6h, 24h, 30h。
10%(w%)管花肉苁蓉提取物的配制:
