The method comprises the following steps: by taking baphicacanthus cusia leaves, baphicacanthus cusia stems and whole baphicacanthus cusia plants as raw materials, sealing, vacuumizing or carrying out nitrogen-filled solid-state fermentation, and extracting with water and an organic solvent to prepare a crude indigo extract; according to the method, the indigo can be efficiently fermented and converted, and the content of indigo in the prepared indigo crude extract reaches 45% or above. The high-purity indigo extract is prepared through purification of different types of ceramic membranes with different molecular weight cutoff and ultrafiltration hollow fiber membranes and extraction and refining of different solvents, the purity of indigo in the indigo extract is higher than 85%, and theoretical reference and technical support are provided for development and application of high-grade dyes and drugs.

Using the stems and leaves of *Indigofera tinctoria* as raw material, a combined high-pressure water extraction technology involving water spray washing and grading, along with steam explosion, was employed to effectively improve the release rate of active substances such as indole glycosides and polyphenols, as well as the conversion rate of indigo. Multifunctional indigo and polyphenol extracts were prepared through bio-fermentation and membrane fractionation purification. The indigo extract contained significantly more bioactive substances than traditional lime-based indigo powder and indigo acidified compounds, with 15 times more indigo, 25 times less ash, and 650 times less calcium. Compared to natural Indian indigo, it exhibited superior dyeing performance on cotton fabrics and showed better inhibitory effects against *Aspergillus niger*, *Staphylococcus aureus*, and *Escherichia coli*. The *Indigofera tinctoria* polyphenol extract, composed of phenolic acids, phenylethyl glycosides, flavonoids, and polysaccharides, demonstrated excellent inhibitory activity against *Staphylococcus aureus* (IC50 = 32 μg / mL) and a wound healing rate exceeding 98% in mice, exhibiting good broad-spectrum antibacterial and wound-healing properties.

The invention discloses an orchard soil improvement and ecological optimization method based on interplanting of Indigofera tinctoria, which comprises the following steps: determining the sowing time and sowing mode of Indigofera tinctoria, processing seed stems of Indigofera tinctoria, and planting Indigofera tinctoria outside a water drip of a fruit tree according to an orchard planting layout diagram; the indigofera tinctoria is subjected to annual fresh grass mowing and field returning according to the requirements of the orchard, and orchard soil improvement and ecological environment optimization are achieved. According to the method, by reasonably planting and managing the indigofera tinctoria, orchard soil improvement and ecological environment optimization are achieved, good conditions are provided for fruit tree growth, and the ecological benefits and economic benefits of an orchard are improved.

The invention discloses a traditional Chinese medicine composition for preventing and treating African swine fever, a pharmaceutical composition and a preparation method, and belongs to the technical field of veterinary use. The invention discloses a traditional Chinese medicine composition for preventing and treating African swine fever. The traditional Chinese medicine composition is prepared from the following raw materials: gypsum rubrum, meadowrue root and rhizome, Chinese mahonia stem, eleusine indica, sculellaria barbata, radix paeoniae rubra, cortex moutan, humifuse euphorbia herb, indigo naturalis, henon bamboo leaf and honeysuckle stem. A pharmaceutical composition for preventing and treating African swine fever is prepared into a veterinary preparation by taking the traditional Chinese medicine composition as a raw material and matching with auxiliary materials. The traditional Chinese medicine composition has good prevention and treatment effects on various viral infections such as African swine fever virus; moreover, the feed additive is low in cost, free of antibiotics and drug residues, capable of being widely applied and capable of solving major problems of the pig raising industry.
