This invention discloses a method for preparing tree tomato leaf extract, its products, and applications, belonging to the field of
natural product extraction and application. The method involves taking tree tomato leaf
powder, using a 60%
ethanol aqueous solution as the extraction
solvent, extracting at a material-to-
liquid ratio of 1:30 g / mL and a temperature of 60°C for 45 min, repeating the extraction twice, combining the two filtrates, concentrating, and
drying to obtain the tree tomato leaf extract. This extract is highly enriched with polyphenols, flavonoids, and other active ingredients, exhibiting multiple effects such as
antioxidant, anti-inflammatory,
tyrosinase inhibition, and promotion of
hyaluronic acid synthesis. It has also been confirmed that it has no significant
cytotoxicity,
phototoxicity, or
skin sensitization. Cosmetic compositions containing this extract can effectively improve
skin hydration,
barrier function, redness, and dullness, and are suitable for preparing multifunctional pharmaceuticals or
cosmetics with anti-inflammatory, whitening, moisturizing, and anti-aging properties, providing strong support for the high-value utilization and development of tree tomato leaf resources.
