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.

The application discloses a respiratory burst oxidase gene StoRBOHB and application of the gene in resistance of Solanum torvum to verticillium wilt, wherein a nucleotide sequence of the StoRBOHB gene is shown as SEQ ID NO. 1, the StoRBOHB gene is induced to express by Lecanicillium dimidiatum, is highly expressed in roots, and responds to ABA, MeJA and SA hormone signals, the gene encodes a protein located on a cell membrane; the StoRBOHB is silenced through a VIGS technology, which significantly reduces the resistance of Solanum torvum to verticillium wilt, and is manifested as that a disease index is increased, H2O2 accumulation is reduced, antioxidant enzyme activity is reduced, and lignin deposition is reduced; and overexpression of the gene enhances the above-mentioned defense response, and overexpression of the StoRBOHB in transgenic Arabidopsis also shows that the resistance to verticillium wilt is significantly improved; the application provides a new gene resource and application scheme for molecular breeding of eggplant resistance to verticillium wilt, and has a wide application prospect in the field of agricultural biotechnology.

The invention relates to the technical field of medicine, in particular to a solanum torvum extract, a preparation method of the solanum torvum extract and application of the solanum torvum extract to preparation of medicine for preventing and treating acute lung injury. The solanum torvum extract has the effects of inhibiting the lung tissue structure damage process of mice with acute lung injury, reducing the dry-wet-weight ratio of lung tissues of the mice with acute lung injury, relieving pulmonary alveolar structure damage, relieving lung tissue edema, inhibiting infiltration of inflammatory cells and improving the inflammatory pathological state of the mice with acute lung injury; according to the application, an acute lung injury animal model is induced by LPS (Lipopolysaccharide) tracheal instillation, solanum torvum water extract and alcohol extract are given through intragastric administration, and the solanum torvum alcohol extract is found to be capable of relieving increase of dry-wet specific gravity of mouse lung tissues and severe lung tissue injury, and reducing the level of inflammatory factors in ALI alveolar lavage fluid and the number of inflammatory cells in serum. The solanum torvum has a good anti-inflammatory effect on the ALI.

The application discloses application of a Solanum torvum extract in preparation of a medicine for preventing and treating non-alcoholic fatty liver and indications thereof, and the Solanum torvum extract comprises one or both of a Solanum torvum water extract and a Solanum torvum alcohol extract; the application is proved by experiments that the Solanum torvum alcohol extract can obviously reduce the weight of a non-alcoholic fatty liver NAFLD mouse; the Solanum torvum water extract can obviously reduce the inguinal white fat; the Solanum torvum extract can obviously reduce a liver weight / body weight index, a liver triglyceride (TG) content, liver lipid deposition, and liver function damage indexes, i.e., glutamic-oxalacetic transaminase (AST) and glutamic-pyruvic transaminase (ALT). The Solanum torvum extract can also reduce serum triglyceride (TG) and cholesterol (TC) levels of the mouse, improve lipid levels, and therefore has an important role in treating non-alcoholic fatty liver.
