The invention belongs to the technical field of biology. The invention particularly relates to application of the tea tree internode length related gene CsUGT708AC25 in reducing the internode length of a poplar and a tea tree. The invention discloses application of a seedling stage molecular marker of a tea tree internode length associated gene CsUGT708AC25. The seedling stage molecular marker is used for identifying whether the tea tree internode length associated gene CsUGT708AC25 belongs to a short internode plant or not. The invention also provides a CsUGT708AC25.1 gene. The application of the CsUGT708AC25.2 gene is as follows: the internode length of a plant is negatively regulated; and the CsUGT708AC25.1 gene and the CsUGT708AC25.2 gene are silenced, so that the content of vitexin and isovitexin in the tea tree body can be inhibited.

The addition amount of isovitexin in the product is 1-10 μg / mL. The isovitexin composition comprises isovitexin and resveratrol, with a mass ratio of isovitexin to resveratrol of 1:9-9:1. The addition amount of the isovitexin composition in the product is 10 μg / mL. This invention has the advantage of being applicable to the preparation of products with oil-controlling effects.

The application discloses a prepared product of king-stargrass and a preparation method thereof, and belongs to the technical field of traditional Chinese medicine preparation. The method comprises the following steps: S101, blanching: blanching the king-stargrass in boiling water for 2-4 minutes until the seed coat has small cracks, quickly taking out, and draining water until the water content is 45-60%; S102, airing: airing the king-stargrass until the water content is 25-35%; S103, soaking: soaking the king-stargrass with vegetable oil for 2-3 hours, and the dosage of the vegetable oil is 8-15% of the weight of the king-stargrass; S104, frying: frying the king-stargrass at 165-180 DEG C for 30-40 seconds until the king-stargrass is completely popped; and S105, cooling: cooling the king-stargrass. The popping rate of the prepared product of the king-stargrass is 90-94%, the content of king-stargrass flavonoid glycoside is between 0.2-0.3%, the content of isovitexin-2''-O-arabinoside is greater than 0.08%, and the content of fatty oil is 5.0-5.7%.

The present application relates to the technical field of pharmaceutical chemistry, in particular to a preparation method and application of a berberine and isovitexin nanomedicine. The application is used in the preparation of a drug for treating diseases related to inflammation mediated by neutrophils. The berberine and isovitexin or the structural analogues of berberine and isovitexin form nanoparticles in a carrier-free form through self-assembly. The berberine and isovitexin nanomedicine has a synergistic anti-inflammatory and antioxidant effect, can efficiently inhibit key inflammatory mediators, realize high-efficiency anti-inflammatory and antioxidant synergy, and significantly improve the effect of preventing and treating acute inflammation.

This invention relates to the field of traditional Chinese medicine component analysis technology, specifically to the fingerprint spectrum of Juanxiao tablets and its establishment method. The method for establishing the fingerprint spectrum of Juanxiao tablets includes: using isoharonidin, isovitexin, rutin, hesperidin, lemon balm glycoside, aloe-emodin, nobiletin, and citrus reticulataein as reference standards, and Juanxiao tablets as the test sample; using HPLC to detect the reference standards and the test sample, and then comparing and analyzing them to determine the common characteristic peaks of Juanxiao tablets; wherein the HPLC conditions include: a C18 column, mobile phase A as a nitrile solvent, mobile phase B as a 0.05-0.15% phosphoric acid solution, and gradient elution. This method can effectively detect characteristic peaks, reduce the drying of impurity peaks, and the obtained fingerprint spectrum has high resolution and good peak shape. All characteristic peaks are baseline separated, enabling a more comprehensive and accurate evaluation of the quality of Juanxiao tablets.
