Description

一种具有抗氧化功效的复合多糖含片
技术领域
本发明属于保健品领域，具体涉及以一种树莓、沙棘、白刺多糖为原料制备所得的复合多糖含片及其用途。
技术背景
随着现代生活节奏的加快，社会竞争的加剧，人们的体力、脑力、心理等疲劳长期积累，加之饮食不健康、环境辐射增多等因素，导致人体内自由基过多，使越来越多的人处于“亚健康”状态。自由基是指那些游离存在的，含有1个或1个以上不配对电子的分子、离子、原子或原子团，具有很大的能量。它们是机体正常代谢的产物，在体内有很强的氧化反应能力。正常情况下，机体的氧化与抗氧化处于一种动态平衡。平衡状态下，自由基作为机体的正常代谢产物，是机体不可缺少的活性物质。一旦平衡被打破，自由基便会产生强大的伤害作用，造成生物膜的脂质过氧化损伤、引起酶、氨基酸、蛋白质的氧化破坏，对内脏器官、免疫系统的形态功能产生影响，从而引起动脉粥样硬化、肿瘤、帕金森综合征等多种由于自由基水平升高而导致的疾病。因此，清除过剩的自由基对于维持机体健康，预防多种疾病都有极为重要的意义。
随着人们对浆果认识的逐渐加深和保健意识的不断提高，树莓、沙棘、白刺等营养丰富的浆果越来越受到欢迎。本发明利用树莓、沙棘、白刺浆果提取的多糖制备成多糖复合含片，打破了浆果传统食用方式，对于进一步实现浆果的精深加工和高值化利用具有非常重要的意义。
发明内容
本发明的目的在于提供一种基于树莓、沙棘和白刺三种浆果制备所得多糖的复合含片。本发明的另一目的在于提供该含片的用途。
具体地，本发明提供了一种具有抗氧化功效的复合多糖含片，它是包括如下重量配比的原辅料制备而成：
原料：树莓多糖3～18份、沙棘多糖4～16份、白刺多糖3～20份。
辅料适量：包括淀粉、糊精、蔗糖、微晶纤维素或硬脂酸镁。
进一步地，其原料重量配比如下：
树莓多糖5～15份、沙棘多糖5～15份、白刺多糖5～15份。
本发明一个具体实施方式中，使用的配比为：树莓多糖:沙棘多糖:白刺多糖＝1:1:1。
多糖是天然有机化合物中的一类大分子物质，由单糖基通过糖苷键连接而成。越来越多的国内外研究证明某些活性多糖具有抗肿瘤、增强免疫力、抗氧化、降血糖、保肝等多种药理活性，具有很高的医疗和保健价值。沙棘多糖是由半乳糖、阿拉伯糖、甘露糖和葡萄糖组成的中性多糖，具有很强的自由基清除能力。此外，沙棘多糖在免疫调节、治疗肝炎、抑菌等方面有较高的临床利用价值。白刺多糖是由葡萄糖、鼠李糖、阿拉伯糖、半乳糖、半乳糖醛酸和甘露糖组成的多糖，具有较强的免疫调节和体外抗氧化活性。树莓多糖是由鼠李糖、阿拉伯糖、木糖、甘露糖、葡萄糖和半乳糖组成的中性多糖，具有清除自由基、抗肿瘤、降血糖、免疫调节、抗疲劳等多种生理活性。
进一步地，其辅料重量配比如下：
辅料：淀粉15～45份，蔗糖10～25份，微晶纤维素15～27份，硬脂酸镁0.5～2份。
更进一步地，其辅料重量配比如下：
淀粉20～40份，蔗糖15～20份，微晶纤维素19～24份，硬脂酸镁1份。
其中，所述的树莓多糖、沙棘多糖、白刺多糖，分别是以树莓、沙棘或唐古特白刺为原料，经过水提或榨汁后，醇沉制备得到；进一步地，醇沉时加入乙醇至含醇量达到70～85％v/v。
本发明还提供了上述具有抗氧化功效的复合多糖含片在制备抗氧化的药物、保健品或功能食品中的用途。
进一步地，所述药物、保健品或功能食品是清除ABTS自由基、超氧阴离子自由基或羟自由基的药物、保健品或功能食品。
优选地，所述药物、保健品或功能食品是清除ABTS自由基或超氧阴离子自由基的药物、保健品或功能食品。
本发明研究发现，树莓多糖、沙棘多糖和白刺多糖均具有良好的体外抗氧化活性，可显著清除羟自由基、超氧阴离子自由基及ABTS自由基。但是将三种多糖组合后，在与单用各多糖相同浓度下，组合物抗氧化活性明显增强(尤其是对ABTS自由基或超氧阴离子自由基)，这说明三种多糖具有协同增效作用。
多糖成分容易吸湿，不宜贮存和生产；且流动性不佳，不便于生产包装。鉴于上述情况，本发明将树莓、沙棘、白刺多糖制备成复合含片，即便于产品的贮存、运输和包装，同时也便于各类人群使用。
附图说明

图2树莓、沙棘、白刺多糖及三种多糖组合对超氧阴离子自由基的清除能力
图3树莓、沙棘、白刺多糖及三种多糖组合对羟自由基的清除能力
具体实施方式
本发明中，各多糖可以按照目前已有的技术进行制备，也可以通过购买市售产品获得。本发明中多糖参照现有技术制备，方法如下：分别取树莓、沙棘或唐古特白刺，经过水提或榨汁后，加入乙醇至70～85％v/v，沉淀制备得到。
试验例1体外抗氧化活性实验

(3)ABTS清除能力：将ABTS溶解(+H2O)至终浓度为7mmol/L，过硫酸钾配制成2.45mmol/L，将二者溶液混合，放置于黑暗，室温条件下搅拌16h；而后将ABTS混合溶液用PBS溶液(PH＝7.0)稀释到其吸光值(于734nm处测)为0.70±0.02；树莓、沙棘、白刺三种多糖及三种多糖组合物分别用蒸馏水溶解后稀释至不同浓度(0.5mg/mL，1mg/mL，2mg/mL，4mg/mL，8mg/mL和16mg/mL)；最后将上述不同浓度的样品加入到ABTS混合溶液中，其样品与ABTS混合溶液比例为1:20，混合后于室温下孵育6min，于734nm处测定吸光值。根据公式计算出清除率。ABTS清除率(％)＝(1-样品吸光值/空白吸光值)×100％。结果见图1。
(4)超氧阴离子自由基清除能力：采用黄嘌呤/黄嘌呤氧化酶产生超氧阴离子自由基体系测定对超氧自由基的清除能力。将树莓、沙棘、白刺三种多糖及三种多糖组合物分别用蒸馏水溶解后稀释至不同浓度(1mg/mL，2mg/mL，4mg/mL，8mg/mL，16mg/mL)。各组依次加入75mmol/L磷酸盐缓冲液(pH7.8)1ml、样品0.2ml(对照组用蒸馏水代替)、0.1mol/L盐酸羟胺溶液0.1ml、75mmol/L黄嘌呤溶液0.1ml和0.037U/ml黄嘌呤氧化酶溶液0.1ml，混合均匀后27℃孵育30min。再加入2ml显色剂(0.4g/L甲萘胺+4g/L对氨基苯磺酸)，混匀后静置5min，530nm下侧吸光值。根据公式计算出清除率。超氧阴离子自由基清除率(％)＝1-样品吸光值/空白吸光值×100％。结果见图2。
(5)羟自由基清除能力：采用Fenton反应原理产生羟自由基，用番红染料显色发来测定对羟自由基的清除能力。将树莓、沙棘、白刺三种多糖及三种多糖组合物分别用蒸馏水溶解后稀释至不同浓度(1mg/mL，2mg/mL，4mg/mL，8mg/mL，16mg/mL)。各组依次加入0.15mol/L的Tris-HCl缓冲液(pH7.4)1ml、0.04mg/ml番红溶液1ml、蒸馏水1ml、0.945mmol/L的EDTANa-Fe2+溶液(pH7.4)0.5ml、样品0.5ml和1％H2O2溶液0.5ml，于37℃孵育30min，对照组用蒸馏水代替，空白组EDTANa-Fe2+溶液和样品用蒸馏水代替。在520nm下检测吸光值。根据公式计算出清除率。羟自由基清除率(％)＝1-样品吸光值/空白吸光值×100％。结果见图3。
