This invention relates to a method for preparing a fern-like beverage. Fern-like fern (Pteris tigrinosa) is a plant belonging to the genus *Pteris* in the family Pteridaceae. The young leaves of *Pteris tigrinosa* are edible because they have a refreshing cucumber-like aroma, hence the common name "cucumber-scented fern." The purpose of this invention is to provide a method for preparing a high-quality fern-like fern beverage, taking advantage of the fern's rich content of various beneficial components and its cucumber-like aroma. The preparation method involves adding taste-adjusting ingredients to water and mixing thoroughly. Cleaned young fern shoots, processed to a size of 1 mm to 10 mm, are then added to the solution. The mixture is mixed thoroughly, bottled, and the bottled fern-like fern beverage is sterilized in a water bath at 70℃-100℃ for 30 minutes to obtain the finished product. This invention is beneficial for the development and utilization of fern-like fern in beverages.

The invention provides an assembled and annotated chloroplast genome of euphorbia splendens, and relates to the fields of molecular biology and plant genetics. The chloroplast genome of the pteris amurensis is a single cyclic molecule; the total length of the chloroplast genome of the psidium aquilinum is 149180bp; the nucleotide sequence of the chloroplast genome of the pteris amurensis is as shown in SEQ ID NO. 1; the GC content of the chloroplast genome of the pteris amurensis is 43.14%; the pteridium aquilinum chloroplast genome provided by the invention enriches a pteridium gene database, lays a foundation for exploring pteridium aquilinum evolution history and an adaptation mechanism of pteridium aquilinum to environmental stress, decrypts genetic codes of pteridium aquilinum from a molecular level, and is applied to biodiversity protection, plant ecological restoration and gardening.

This invention discloses a method for breaking the cell wall of Pteris vittata spore powder, comprising grinding and breaking the cell wall: placing Pteris vittata spore powder in a grinding tube, and mixing it with a material-to-liquid ratio of 1:(80-90) g / mL. ‑1 Distilled water was added in a specific ratio, and the grinding tube containing the *Pteris vittata* spore powder and distilled water was placed in a tissue homogenizer. The homogenizer was turned on to lower the temperature to below 4°C, and then the cells were ground to break the cell walls, resulting in a suspension of broken *Pteris vittata* spore powder. This cell wall breaking method can break the outer shell of *Pteris vittata* spores, achieving a cell wall breaking rate of over 95.15%, while greatly preserving the active ingredients in the broken *Pteris vittata* spore powder. This invention also confirms that *Pteris vittata* spores have the same efficacy as the whole *Pteris vittata* herb extract and are an important component of *Pteris vittata* medicinal materials. This invention also discloses a *Pteris vittata* spore powder and its uses.
