Abstract
本发明旨在以最有效的方式增强绿茶提取物如儿茶素的各种效果。所述绿茶提取物中所含的表没食子儿茶素没食子酸酯(A)与柑橘类提取物中所含的黄烷酮糖苷(B)的比(B/A)为0.2<B/A<1.6,或表没食子儿茶素没食子酸酯(A)与所述柑橘类提取物中所含的圣草次苷(C)的比(C/A)为0.2<C/A<0.5。
Description
技术领域
本发明涉及包含儿茶素等绿茶提取物和柑橘类水果提取物或黄烷酮糖苷的组合物、功能性食品等。
背景技术
近年来,癌症占日本死亡人数的三分之一,因此迫切需要建立针对癌症治疗的适当治疗手段。在多发性骨髓瘤中,现在通过引进来那度胺和硼替佐米(即蛋白酶体的特异性抑制剂)改善了治疗环境。另一方面,很多病例是癌细胞对现有药物产生抗性,从而导致复发。为此,需要开发具有与常规药物不同的作用机制的抗癌剂。此外,这样的抗癌剂与现有疗法如果它们的剂量限制性毒性(DLT)不同,就可以联合使用,这使得能够制定更有效的治疗策略。
EGCG(表没食子儿茶素没食子酸酯、表没食子儿茶素-O-没食子酸酯)是绿茶中所含的主要儿茶素之一,据报道具有抗癌效果(非专利文献1),并已在患有慢性淋巴细胞白血病—一种血液癌症—的患者中进行了II期临床试验(非专利文献2)。虽然已知EGCG通过与细胞膜上的其靶分子67-kDa层粘连蛋白受体(67LR)结合而发挥抗癌效果,但EGCG对白血病细胞或多发性骨髓瘤细胞的致死效果有限(非专利文献2)。因此,强烈需要在EGCG用作抗癌剂时增强其效果。
专利文献1公开了,柑橘类水果提取物或黄烷酮糖苷增强儿茶素的抗癌效果和其它效果,包含儿茶素等绿茶提取物与柑橘类水果提取物或黄烷酮糖苷的组合物具有多种效果,例如抗癌效果、抗肌萎缩效果和抗肥胖效果。
