Embodiment 1-4

[0075] Example 1-4: Preparation of myrtle extract

Embodiment 1

[0077] 100 kg of myrtle leaves and dried fruit are ground and then extracted with 700 kg of 50% ethanol. Extraction was performed at reflux and stirred for 1 hour. The solution was collected after filtration and then concentrated under reduced pressure at 60°C. The concentrate is then dried until a dry substance is obtained having a polyphenol content of 20 to 40% and a flavonoid content of 1.5 to 3.5%.

Embodiment 2

[0079] The first step was the same as in Example 1, but the procedure for the final concentration and drying steps was different. After the extraction and during the concentration, 200 kg of propylene glycol were added and the concentration was continued until a solution weighing 220 kg was obtained. The dry matter content is 8 to 12%, the polyphenol content is 20 to 40% relative to the dry matter, and the flavonoid content is 1.5 to 3.5% relative to the dry matter.

Background technique [0003] first: [0004] Skin pigmentation is due to the synthesis of melanin by specialized cells (melanocytes). Melanin is a pigment that can take on different molecular forms, melanin and its derivatives - pheomelanin, pheomelanin and its derivatives - yellow - red pigment. Melanocytes are located in the basal layer of the epidermis and they have cytoplasmic or dendritic extensions required for the transport of melanin. Melanin is in the...
