Description
技术领域
本发明属于生物化学技术领域,具体涉及一种高原儿茶酸负载香菇菌多糖复合物的制备方法及应用。
背景技术
香菇菌多糖,它既是水溶性的,又是电中性的,因此更加适合于化妆品的应用,其拥有优异的抗衰老功效,能够抚平细小皱纹,改善皮肤纹理度。赋予了产品良好的透皮吸收性能,可作为活性成份的释放载体,给予皮肤如丝绸般滋润光滑的触感。
高原儿茶酸,又称3,4-二羟基苯乙酸,在植物中以游离或聚合的形式存在,是酚酸类主要成分之一。它还是重要的生化检测试剂,在生物化学方面的研究和应用一直非常活跃[1]。具有此结构的化合物显示出较多的生理活性,如抗氧化、抗菌、抗病毒、保肝、治疗中枢神经性疾病、抑制环氧酶及酯氧酶的活性等。
痤疮等皮肤问题可由炎症引起,通过抑制炎症并改善皮肤状态可有效改善痤疮、皮肤衰老等问题。在护肤产品中,往往需要搭配多种来产生协同作用起到抑制炎症同时改善皮肤。

具体实施方式
下面将结合具体的实施方案对本发明进行进一步的解释,但并不局限本发明。
下述实施例中,如无特殊说明,所用方法为常规方法,所用试剂都来源于市售商品。
实施例1.高原儿茶酸负载香菇菌多糖复合物对炎症因子TNF-α和IL-1 β的影响检测
检测方法:
小鼠巨噬细胞RAW264.7接种于12孔板内,37℃,5%CO2培养箱培养 24h后,加入40mg/L脂多糖(LPS)作用4h诱导炎症反应,适当浓度的DT001、 GK2、Drag和Hydr于LPS加入前2h加入。LPS作用4h后,收集细胞上清,按照ELISA试剂盒说明书测定TNF-α和IL-1β的含量。
结果如图1所示。
结论:
DT001显著抑制LPS诱导引起的炎症因子TNF-α和IL-1β含量的上升,且效果显著优于阳性药甘草酸二钾和红没药醇,其抑炎效果与糖皮质激素氢化可的松效果相当。
实施例2.对小鼠足趾肿胀的影响检测
检测方法:
1%羧甲基纤维素钠配药,使成凝胶状,并在每鼠右下足趾正反两面均匀涂抹药物。半小时后,每鼠左右两足趾均皮下注射1%角叉菜胶约0.025mL,空白对照组小鼠不做处理。5h后脱颈处死,沿踝关节减下左右两足,称重,计算肿胀度及肿胀率,并做统计分析。
肿胀度=炎症组足趾重量-空白组足趾重量
结果如图2所示。
结论:
DT001显著抑制角叉菜胶对小鼠足趾造成的肿胀,且效果显著优于阳性药甘草酸二钾和红没药醇,其抑炎效果略优于糖皮质激素氢化可的松。
实施例3.DT001对成纤维细胞增殖影响的检测
护肤品对抗炎的治疗过程中还涉及皮肤损伤处的修复,而成纤维细胞的增殖是主要的表现形式。本部分实验检测DT001及三种阳性药物甘草酸二钾 (GK2)、红没药醇(Drag)和氢化可的松(Hydr)对成纤维细胞NIH-3T3 的增殖影响。实验方法及结果如下:
检测方法:
小鼠成纤维细胞NIH-3T3以5000cells/孔密度接种于96孔板内,37℃, 5%CO2培养箱培养12h左右待细胞贴壁,适当浓度的DT001、GK2、Drag 和Hydr加入到对应孔内,同时设一组空白对照,每组5个重复。继续培养48 h后,每空加25μL MTT并继续孵育4h。随后DMSO溶解甲瓒并用酶标仪检测OD490吸光值,对数据做统计分析。
结果如图3所示。
结论:
DT001显著促进成纤维细胞增殖,且效果优于阳性药甘草酸二钾和红没药醇,其抑炎效果与糖皮质激素氢化可的松效果相当。
实施例4.DT001对皮肤改善情况的检测
检测方法:
招募30名志愿者(其中15男,15女),随机分为5组(对照、DT001、 GK2、Drag、Hydr),其中每组男女各3人。每次使用时先用湿巾或水洗将右手手腕内侧清理干净,随后护肤品均匀擦拭于右手手腕内侧部位,每天早晚各一次,连续使用4周共28天。分别于第0、7、14、28天使用DermaLab 仪器检测TEWL(经表皮水流失)、Ultrasound(超声)、Elasticity(弹性) 和Skin Color(肤色)共四项指标,每次检测时志愿者右手手腕内侧湿巾擦拭干净并晾晒20分钟左右至晾干后开始检测。仪器所在房间不通风,无阳光直射,室温保持在24-25℃,湿度保持在40%。最后对得到的数据做统计分析。
结果:
表1.对照组皮肤改善情况:
表2.DT001对皮肤的改善情况(DT001:高原儿茶酸负载香菇菌多糖复合物):
表3.甘草酸二钾对皮肤的改善情况(GK2:甘草酸二钾):
表4.红没药醇对皮肤的改善情况(Drag:红没药醇):
表5.氢化可的松对皮肤的改善情况(Hydr:氢化可的松):
结论:
DT001可有效改善皮肤的保水性能,提高皮层胶原蛋白含量,改善皮肤弹性。对保水性能的最高改善率优于红没药醇,与甘草酸二钾和氢化可的松效果相当;对胶原蛋白含量的改善优于三种阳性药;对皮肤弹性的最高改善率优于氢化可的松,与甘草酸二钾和红没药醇效果相当。与对照组比较,DT001 对皮肤的改善效果优于甘草酸二钾、红没药醇和氢化可的松。
