Embodiment 1

[0017] Example 1. Preparation of raspberry extract

[0018] 50 kg of dried fruit of raspberry palmate was extracted by percolation with an aqueous solution as usual, and the extract was concentrated under reduced pressure to a non-alcoholic extract to obtain 12.6 kg of raspberry extract.

Embodiment 2

[0019] Example 2. Preparation of raspberry extract

[0020] 50 kg of dried fruit of raspberry palmate was extracted by percolation with a 95% solution as usual, and the extract was concentrated under reduced pressure to an alcohol-free extract to obtain 2.4 kg of raspberry extract.

Embodiment 3

[0021] Example 3. Preparation of raspberry extract

[0022] 50 kg of dried fruit of raspberry palmate was extracted by percolation with 70% ethanol aqueous solution as usual, and the extract was concentrated under reduced pressure to a non-alcoholic extract to obtain 6.5 kg of raspberry extract.
