The present application relates to the technical field of antioxidant composition, and is an antioxidant composition containing water extract of ferula, and a preparation method and application thereof.The antioxidant composition containing water extract of ferula takes water extract of ferula as the core, and is compounded with hawthorn powder, rose powder and inulin to build a multiple antioxidant synergistic mechanism, wherein the water extract of ferula is responsible for removing free radicals and inhibiting inflammatory factors, the hawthorn powder and the rose powder further remove excess free radicals in the body, and the inulin reduces intestinal-derived oxidative toxins from the source, thereby significantly enhancing the antioxidant capacity of the antioxidant composition containing water extract of ferula of the present application.Meanwhile, the composition has good anti-tumor and anti-inflammatory pharmacological activities, and has a wide application prospect in the field of health.

This invention relates to a class of compounds extracted from the whole herb of Ferula assa-foetida, their preparation methods, and applications, belonging to the field of pharmaceutical technology. It also includes a class of compounds having the following chemical structural formula and their pharmaceutically acceptable salts. This invention provides for the first time a method for preparing and identifying six new compounds using whole Ferula as a raw material, and systematically evaluates their anti-inflammatory activity, clarifying their application in the development of anti-inflammatory drugs.

The application relates to a resin collecting method of medicinal ferula and a planting method of the medicinal ferula. The planting method of the medicinal ferula comprises the steps of site selection, field management and continuous resin collecting. After the ferula plants grow for 5-8 years and enter the vigorous nutrition period, resin is collected from the stem base in a directional way: soil is vertically taken out on one side of the plant to form a U-shaped section pit on the side of the plant, 1 / 3-1 / 2 of the side of the ferula rhizome is exposed, a thin slice is cut off from the base of the exposed ferula rhizome by using a sharp knife to form a wound surface, resin of the ferula is naturally secreted from the wound to be collected, thus, resin can be continuously collected for 2-4 times every year, and the ferula can be continuously collected for 3-5 years, so that the artificial planting of the ferula is improved in quality and efficiency, and resource sustainable utilization is maintained. The resin collecting method can continuously collect resin for multiple times until the ferula blossoms, the technical defect that the traditional resin collecting is once and the plant is destroyed is solved, an efficient production system of'multi-year planting, annual resin collecting, continuous income and plant reservation' is established, and in particular, the artificial planting of the ferula is improved in quality and efficiency, and resource sustainable utilization is realized.

This invention belongs to the field of phytochemistry and pharmaceutical technology, specifically disclosing a method for preparing and purifying sesquiterpene coumarin compounds isolated from *Ferula samarkand*, including the structures of three sesquiterpene coumarin compounds isolated from *Ferula samarkand*, and the process for separating sesquiterpene coumarins. Addressing the current problem of unclear chemical composition and active ingredients of *Ferula samarkand*, this invention employs organic solvent extraction, concentration, and then utilizes two to three methods—normal-phase silica gel column chromatography, dextran gel chromatography, low-to-medium pressure rapid preparative chromatography, and semi-preparative high-performance liquid chromatography—for separation, ultimately yielding three sesquiterpene coumarin monomers. This solves the problem in existing technologies where the unclear chemical composition and active ingredients of *Ferula samarkand* make it difficult to separate and purify sesquiterpene coumarins.
