EXAMPLES Next, the present invention will be described in more detail with reference to Reference Examples, Test Examples and Examples, but the present invention is not limited thereto.

Reference Example 1 Production of Pineapple Fruit Juice A pineapple fruit was crushed and strained by a conventional method to remove the pericarp, excess pulp, and the like to obtain a pineapple juice. Next, the pineapple fruit juice was circulated several times at high speed using a grinder to perform a fine treatment. The obtained processing liquid is centrifuged and centrifuged to separate a sediment containing most insoluble solids and a liquid part (solids 7%) containing a part of pulp, and this liquid part is separated. Obtained as pineapple fruit juice.

Reference Example 2 Production of Pineapple Fruit Extract 10 g of pineapple fruit was crushed by a conventional method and
1% 1,3-butylene glycol solution, and 50 vol
100 mL of ethyl alcohol at room temperature.
After extraction for one day, filtration was performed to obtain each extract. The dry solids of these extracts were 2.0% and 2.3%, respectively.

Reference Example 3 Preparation of Yokuinin Extract To 10 g of Yokuinin (JP), 100 mL of 70 vol% ethyl alcohol was added, extracted at room temperature for 3 days, and filtered to obtain a Yokuinin extract. At this time, the dry solid content of the yokunin extract was 0.8%.

Test Example 1 Inhibition of Melanin Production and Cell Viability Test by Cell Culture B16 melanoma cultured cells derived from mice were used. 2
An appropriate amount of a MEM medium containing 10% FBS was taken in a 6-well petri dish, B16 melanoma cells were inoculated, and allowed to stand at 37 ° C. in a carbon dioxide concentration of 5%. On the next day, the final concentrations of the pineapple fruit juice and the pineapple extract obtained in Reference Example 1 were converted to solids (0 (control) 100, 500, 1).
The sample preparation was added and mixed to give a concentration of 000 μg / mL. On the fifth day of the culture, the medium was replaced, and the sample preparation solution was added again. On the next day, the medium was removed, and one petri dish was washed with a phosphate buffer and then collected. The degree of whitening of the cultured B16 melanoma cells was evaluated according to the following criteria. Further, as a comparative example, the same test was performed on the yoquinin extract obtained in Reference Example 3 which is already known to have a melanin production inhibitory action.

(Judgment Criteria) +: Clearly white with respect to the control. ±: slightly white compared to the control. -: Same black as the control.

For the remaining one petri dish, the cells were fixed in formalin and stained with a 1% crystal violet solution. Cell viability for each sample concentration was measured with a monocerator (Olympus). Table 1 shows the above results.

(Result)

[Table 1]

* 1 Manufactured in Reference Example 1 * 2 Manufactured in Reference Example 2 * 3 Manufactured in Reference Example 3

As is evident from the results in Table 1, it was confirmed that the pineapple fruit juice and the extract had a high ability to inhibit the production of melanin and had low toxicity to cultured B16 melanoma cells. Therefore, pineapple fruit juice and extract, by applying this to the skin, exerts an extremely excellent melanin production inhibitory action, effectively suppresses skin blackening due to sunburn, spots, freckles, etc. A beautiful skin effect can be expected.
