Embodiment 1-1
[0093] Example 1-1: Preparation of red bean extract
[0094] Wash red beans (red beans or adzuki beans) with water, dry them in a cool place, and grind them into powder using a Waring blender. Add 20 kg of powdered red beans to 100 L of methanol, cold soak and extract for 3 days, filter under reduced pressure with filter paper (Waterman Company, USA), and then use a vacuum rotary concentrator to filter the extract to The methanol solution was removed to obtain 450 g of extraction residue, which is the red bean extract.
Embodiment 1-2
[0095] Example 1-2: Preparation of Fractions
[0096] In order to separate the active fraction from the red bean extract prepared above, after the red bean extract was suspended in 1L of water, an equal amount of n-hexane was added, mixed and graded, and this process was repeated 4 times to obtain 1L of water-soluble Fraction and 4 L of n-hexane soluble fraction.
[0097] Next, the n-hexane-soluble fraction was concentrated under reduced pressure to obtain 50 g of n-hexane-soluble extract.
[0098] In addition, an equal amount of ethyl acetate was added to the 1L water-soluble fraction, mixed and classified, and this process was repeated 3 times, thereby re-obtaining 1L of water-soluble fraction and 3L of ethyl acetate-soluble fraction.
[0099] The obtained ethyl acetate soluble fraction was concentrated under reduced pressure to obtain 35 g of ethyl acetate soluble extract. The remaining water-soluble fraction was concentrated under reduced pressure to 35 g, which was us...
