    • PURPOSE: A composition containing peach leaf extract as an active ingredient is provided to effectively prevent or treat diseases related to neural cell protection. CONSTITUTION: A composition for protecting neural cells contains peach leaf extract as an active ingredient. The peach leaf extract is isolated using water, organic solvent, or mixture solvent thereof. The peach leaf extract is methanol extract. A health food contains the composition for protecting neural cells. A method for purifying a fraction of peach leaf extract comprises: a step of extracting peach leaf; a step of sequencially fractioning with hexane, chloform, and ethylacetate; a step of decompressing and drying the fraction; a step of performing silica gel column chromatography; a step of adding chloroform and methanol to obtain peach leaf extract fraction; and a step of performing TLC(thin layer chromatography) and HPLC(high performance liquid chromatography) to obtain the peach leaf extract fraction.
    • 目的:提供含有桃叶提取物作为活性成分的组合物,以有效预防或治疗与神经细胞保护有关的疾病。 构成:保护神经细胞的组合物含有桃叶提取物作为活性成分。 使用水,有机溶剂或其混合溶剂分离桃叶提取物。 桃叶提取物为甲醇提取物。 保健食品含有保护神经细胞的组合物。 一种用于纯化桃叶提取物的部分的方法包括:提取桃叶的步骤; 用己烷,氯仿和乙酸乙酯顺序分馏的步骤; 减压和干燥级分的步骤; 进行硅胶柱色谱的步骤; 加入氯仿和甲醇以获得桃叶提取物级分的步骤; 以及进行TLC(薄层色谱法)和HPLC(高效液相色谱)以获得桃叶提取物级分的步骤。
