Abstract
本发明公开了一种防晒抗光老化中药组合物及其应用,由有效成分和DMSO组成,其中,有效成分由台湾山芙蓉甲醇回流提取物、延龄草95%乙醇提取物和栀子蒸馏水提取物以4∶3∶3的质量比组成,有效成分在DMSO中的浓度为4‑8mg/mL。本发明具有具防晒和抗光老化功效,可用于化妆品中,达到防晒和抗衰老的效果,尤其适用于太阳光照射导致的皮肤粗糙、皱纹增多、萎黄等;本发明纯天然、无刺激、安全无毒副作用。
Description
技术领域
本发明属于化妆品技术领域,具体涉及一种防晒抗光老化中药组合物及其应用。
背景技术
皮肤老化是一个复杂的生物学过程,分为内源性老化和外源性老化两种类型。内源性老化是随时间推移而发生的皮肤老化,存在基因依赖性。外源性老化是由外界环境因素引起,其中UV辐射为主要因素,占外界影响的80%,因此外源性老化又被称为光老化。
光老化最为显著的临床特征是皮肤干燥、松弛结节、细纹增多、弹性下降以及色斑沉着。组织学上,光老化皮肤的黑色素细胞增多,色素过度沉着,朗格汉斯细胞明显减少,真皮层增厚,胶原蛋白纤维的显著减少,但弹性纤维却大量增多变性。细胞水平光老化的特征主要表现为活性氧自由基(ROS)的过度蓄积以及细胞外基质成分的改变。
研究发现80%~90%的皮肤老化由外源性因素引起,其中UV辐射是加速皮肤衰老的最主要原因。皮肤光老化涉及多种信号分子和多条信号转导通路,其分子机制主要包括DNA损伤、氧化应激、炎症反应、胶原结构改变以及细胞凋亡,UV诱导的光老化机制见开放科学(资源服务)标识码(OSID)。中药中含有丰富的蛋白质和各种氨基酸、脂类、多糖类、黄酮类、维生素、有机酸、生物碱、皂苷等营养物质,其作用机制有修复DNA损伤、抗氧化、抗炎、修复皮肤屏障功能和抗凋亡等,中药在防治和延缓皮肤光老化中起重要作用。

实施例5防晒抗光老化中药组合物效果实验
A清除DPPH自由基能力的研究
使用DPPH自由基清除能力检测试剂盒(碧云天,BC4750)检测多肽清除自由基的活性。取500μL试剂二溶液,冰上解冻后,加入试剂一溶液(无水乙醇)2625μL,充分混匀,置于冰上待用。取ImL试剂盒提供的提取液加入到试剂三的棕色玻璃管中,充分混匀后,分装保存50μL每管,置于-20℃;从-20℃冰箱中取出防晒抗光老化中药组合物储存液,加入DMSO稀释,置于冰上待用同时准备溶剂备用。分光光度计预热30min以上,调节波长至515nm,无水乙醇调零。将10mg/mL维生素C溶液(试剂三)用提取液配制成大于0.3mg/mL的维生素C溶液待用(向储存离心管加入1.2mL的提取液,充分混匀)。在1.5mLEP管中分别加入防晒抗光老化中药组合物溶液、DMSO、提取液以及工作液,使防晒抗光老化中药组合物终浓度为62.5μM、125μM、250μM、500μM、1000μM。混匀后室温避光静置30min,于515nm处的吸光度。空白管、阳性对照管、对照管和测定管的吸光值分别记为A空白、A阳性对照、A对照和A测定。空白管只需测1-2次。仪器开机预热,调试参数。使用仪器进行检测,记录检测数据并分析得出结果如图1所示,防晒抗光老化中药组合物具有较强的自由基清除活性,并且具有浓度依赖性。
B CCK-8法检测防晒抗光老化中药组合物对HaCaT的细胞毒性
将HaCaT细胞种植到96孔板(约4×104/孔),24h细胞完全贴壁后,去除培养基,加入含不同浓度的防晒抗光老化中药组合物的100μL无血清培养基,24h后,向96孔板加入10μL的CCK-8试剂,2h后,在450nm的波长下,检测OD值。结果如图2所示,防晒抗光老化中药组合物在浓度为0~40μg/mL时对HaCaT细胞无毒性,当其浓度达到80μg/mL时,表现出微弱的细胞毒性。
C防晒抗光老化中药组合物对UVB诱导的HaCaT细胞损伤修复活性检测
将HaCaT细胞种植到96孔板(约4×104/孔),24h细胞完全贴壁后,去除培养基,加入含不同浓度的防晒抗光老化中药组合物的100μL无血清培养基预处理24h,之后用PBS洗3遍,采用UVB紫外辐照仪对HaCaT细胞进行一定辐照剂量辐照细胞。HaCaT细胞辐照后,更换1%FBS的新鲜培养基,24h后,向96孔板加入10μL的CCK-8试剂,2h后,在450nm的波长下,检测OD值。结果如图3所示,可以看到,防晒抗光老化中药组合物在浓度为0~40μg/mL时对HaCaT细胞受到的光损伤具有显著的保护作用,当其浓度为80μg/mL时保护作用减弱。
D防晒抗光老化中药组合物对光老化HaCaT细胞中ROS含量的影响
使用DCFH2-DA通过荧光显微镜测定UVB辐射后HaCaT细胞内ROS的产生。首先,HaCaT细胞(1.5×105/孔)在补充有10%FBS的培养基中培养。然后,当达到80%细胞密度时更换新鲜的培养基。一定浓度的防晒抗光老化中药组合物预处理和UVB照射后,用PBS洗涤细胞,与10μM DCFH2-DA在PBS中37℃孵育30min,然后用PBS缓冲液洗涤。最后,在485nm激发和535nm发射记录分光光度计下测量荧光,结果如图4所示,防晒抗光老化中药组合物在浓度为0~40μg/mL时能够显著降低光老化HaCaT细胞中ROS的含量。
E实时荧光定量PCR
使用RNeasy迷你试剂盒(Qiagen,Pudong,Shanghai,China)从经40μg/mL防晒抗光老化中药组合物预处理和UVB诱导过的HaCaT细胞中提取RNA,然后使用GoScript逆转录混合物(Promega,WI)逆转录每个样品500ng RNA。然后将EVA Green Supermix(Bio-Rad,CA)用于实时定量PCR,β-actin用作内参。MMP1、I型胶原和TIMP1的引物用Primer5设计,如表1所示。2-ΔCt方法用于量化相对基因表达。
表1
结果如图5所示,40μg/mL的防晒抗光老化中药组合物能够部分逆转HaCaT细胞因UVB诱导导致的I型胶原蛋白和TIMP1的mRNA表达下降以及MMP1的mRNA表达上调。
F红细胞溶血实验
健康家兔心脏取血7mL,加2%草酸钾溶液1mL,制备成新鲜抗凝兔血,加PBS10mL稀释,4℃冰箱保存备用。配制样品系列溶液。每种样品均设立8个试验剂量必须保证各稀释样品悬液充分混匀。溶血及蛋白变性测定:样品组每个浓度2支具塞试管,每管加入样品悬液10mL;阴性对照组2支具塞试管,每管加入PBS10mL;阳性对照组2支具塞试管,每管加入蒸馏水10mL。每支试管加入0.2mL稀释兔血,轻轻混匀,37C孵育30min。结束后,离心10min,2000rmin,吸取上清液移入比色皿内,于分光光度计540nm,560nm及575nm测其吸光度(A)值。按公式①计算溶血率(%),公式②计算血红蛋白变性指数(D I,%)。其中R1为空白对照蒸馏水的离心上清液A575/A540值;R2为样品离心上清液A575/A540值;R3为阳性对照SDS离心上清液A575/A540值。主要观察指标为50%红细胞发生溶血时的样品浓度(HD50)、蛋白质变性指数(DI)、HD50与变性指数DI的比值(IP=HD50/D I)。
结果如图6所示,防晒抗光老化中药组合物浓度在100μg/mL以下呈不溶血。
以上所述,仅为本发明的较佳实施例而已,故不能依此限定本发明实施的范围,即依本发明专利范围及说明书内容所作的等效变化与修饰,皆应仍属本发明涵盖的范围内。
