Embodiment 1
[0079] Embodiment 1: the preparation of extract
[0080] 1.1: Preparation of Korean angelica extract
[0081] 1.1.1. Preparation of 98% ethanol extract
[0082] Wash the root of Angelica gigas Nakai with water and dry it well. Dried Angelica root was crushed, 5 times the volume (500ml) of ethanol (98% (v / v) ethanol (alcohol)) was added to 100g of the resulting powder, and extracted at a temperature of 40 to 60°C for 4 hours or longer, and then filtered through a 1 μm (micron) filter, the filtrate was heated and concentrated until it became 10% by weight of the original weight. Crystalline cellulose was gradually added to the obtained concentrate, continuously concentrated, completely dried, and then pulverized to prepare Korean angelica ethanol extract powder (hereinafter referred to as AGE).
[0083] 1.1.2. Preparation of 90% ethanol extract
[0084] Wash the Korean angelica root with clean water and dry it well. Dried Angelica root was crushed, 5 times the volume (500ml...
Embodiment 2
[0089] Example 2: Neuroprotective activity test
[0090] beta-amyloid 1-42 (American Peptide, USA) and β-amyloid 42-1 (Bachem, Switzerland) was dissolved at a concentration of 37 µl / µl in sterile 0.1 M phosphate buffer (pH 7.4), and stored until the prepared solution was used. On the other hand, the 200 mg / kg Korean angelica ethanol extract (AGE) prepared in Example 1.1.1, the 400 mg / kg broccoli ethanol extract (BKE) prepared in Example 1.2, or the 200 mg / kg Korean angelica ethanol The mixture of extract (AGE) and 400mg / kg broccoli ethanol extract was dissolved in 10ml of distilled water, and then administered to the normal mice (ICR mice; body weight 18-26g, every group of 5 mice) prepared in Example 1.3 once a day mice) for 4 weeks. For comparison, administration of distilled water in an amount of 10 ml instead of the above-prepared extract was prepared as a control group. In the bregma of mice to which the extract was administered for 4 weeks, injection was performed at...
Embodiment 3
[0096] Example 3: Nerve regeneration activity test
[0097] Mice induced by genetic manipulation for Alzheimer's disease (3xTg-AD, AD triple transgenic mouse model, 12 months old, hereinafter referred to as "3X-TG mice"; THE JACKSON LABORATORY (USA); female , 4 mice in each group, weighing about 40 g). These mice gradually express plaques and tangles, and show learning and memory deficits.
[0098] 3X-TG mice prepared at the age of 12 months were orally administered for 6 weeks, wherein the 200 mg / kg Korean angelica ethanol extract (AGE) prepared in Example 1.1.1 and / or the 400 mg / kg prepared in Example 1.2 were administered orally for 6 weeks. Broccoli ethanol extract (BKE) was dissolved in 10 ml of distilled water and administered alone or in combination 6 times a week for 6 weeks. For comparison, a group administered with 10 ml of distilled water instead of the extract was prepared as a control group. The same test was performed using B6129SF2 / J mice (female; 4 mice, bod...
