This invention belongs to the field of traditional Chinese medicine composition technology, and discloses an anti-fatigue composition, its preparation method, and its application. The invention provides an anti-fatigue composition comprising the following raw materials in parts by weight: 15-25 parts ginseng, 15-25 parts astragalus, 8-18 parts poria cocos, 5-15 parts tangerine peel, 5-10 parts wolfberry, 4-8 parts olive, 3-7 parts elsholtzia ciliata, 1-5 parts extract of *Iris tectorum*, 1-5 parts enzymatic extract of *Iris tectorum*, and 3-8 parts licorice. The components of this composition work synergistically to clear damp-heat, unblock meridians, and enhance the heat-clearing effect. It can improve the bioavailability of qi-tonifying herbs, making the entire formula warm without being drying, and tonifying without being hot, thus realizing the therapeutic principle of eliminating pathogens to support the body's resistance, resulting in a significant anti-fatigue effect.

The preparation method comprises the following steps: crushing and sieving iris tectorum roots, carrying out an enzymatic hydrolysis reaction by using a compound enzyme, and sequentially carrying out multi-stage membrane separation treatments of microfiltration membrane impurity removal, ultrafiltration membrane enrichment and nanofiltration membrane concentration to finally obtain the high-purity iris tectorum root extract. Through the synergistic effect of enzymolysis and membrane separation technologies, the method effectively destroys the cell wall structure of iris tectorum roots, improves the dissolution rate of effective components, avoids the problems of organic solvent residue, effective component destruction at high temperature and the like in a traditional extraction method, has the advantages of high extraction efficiency, high product purity, greenness, environmental protection and the like, and is suitable for industrial production. The method is suitable for industrial production of the iris root extract.

The invention discloses a rhizopus irregularis BGC BJ09 strain and an application of the rhizopus irregularis BGC BJ09 strain in arsenic wastewater purification of a constructed wetland. The strain can form an efficient mycorrhiza symbiont with Iris tectorum Maxim., so that the resistance of a host plant to arsenic stress is remarkably improved, and the adsorption and conversion efficiency of an artificial wetland to arsenic is enhanced. By optimizing the mycorrhizal symbiosis system, the mycorrhizal infection rate of the iris blue root system reaches 28%-36%, the arsenic removal rate of the constructed wetland is increased to 80%-95% from 50%-65% of a traditional method, and the arsenic concentration of effluent is stably lower than 0.05 mg / L. The method has the advantages of being easy and convenient to operate, low in cost, environmentally friendly and the like, and is suitable for arsenic-polluted water body remediation and coastal buffer zone ecological landscape construction.

This invention provides a method for establishing a rapid propagation system of *Iris tectorum* through tissue culture using autumn dormant buds. The method uses autumn dormant buds of *Iris tectorum* as explants. Aseptic buds are obtained by removing the base and excess above-ground parts, fixing, peeling, and clamping. The buds are then longitudinally cut to increase the propagation coefficient, inducing clustered lateral buds, and then inducing rooting to form aseptic mature plants. The aseptic rate after 7 days is 57.12%, and the fungal rate is 0.15%. The aseptic rate after 20 days of the first subculture is 84.66%, and the rooting rate after 50 days is 63.33%. This method eliminates the need for callus induction and differentiation stages, significantly shortening and simplifying the time and procedure for obtaining aseptic *Iris tectorum* seedlings. The method is easy to control, low in cost, and highly efficient. It provides a new approach for further subculture or callus redifferentiation to establish a highly efficient rapid propagation system for monocotyledonous plants, and provides a solid foundation for the breeding, asexual reproduction, polyploid breeding, and even genetic engineering breeding research of *Iris tectorum* original species and varieties.

The present application relates to the technical field of skin care products, and discloses a plant extraction compound with firming and anti-wrinkle effects, a preparation method and application thereof, and the plant extraction compound with firming and anti-wrinkle effects comprises the following components in mass fractions: 84.8-89.2 parts of a solvent; 0.8-1.2 parts of a preservative; and 10-14 parts of a moisturizing and anti-aging composition. The moisturizing and anti-aging composition is a compound of Chondrus crispus extract, Buddleja lindleyana extract, Iris tectorum rhizome extract, Ledum palustre extract, Ganoderma lucidum extract and Panax ginseng extract. The present application has the advantages of improving anti-wrinkle effects.

This invention relates to the field of industrial biotechnology, and in particular to an induction culture medium for inducing embryogenic callus in *Iris tectorum* and its application. This invention uses adventitious roots of *Iris tectorum* as explants, which, after sterilization, are inoculated into the induction culture medium provided by this invention, achieving a high-efficiency culture of *Iris tectorum* callus with high induction rate, low browning rate, uniform growth, and stable state. This invention achieves a callus induction rate of 64.5%–90.6% for adventitious roots of *Iris tectorum*, with an embryogenic callus induction rate reaching 88%, and a browning rate of less than 15%. Simultaneously, this invention solves the technical problems of difficult sterilization of explants in the *Iris* genus, severe browning, low callus induction efficiency, and poor system stability, establishing a unified, simple, reproducible, and scalable *Iris tectorum* callus culture system, providing stable recipient materials and a technical foundation for *Iris tectorum* research.
