This invention relates to the field of traditional Chinese medicine extracts and drug preparation technology, and discloses a *Hypericum perforatum* extract composition, its preparation method, and its application, including the application of an ethanol extract of *Hypericum perforatum* or components isolated from its ethanol extract in the preparation of drugs for the prevention and / or treatment of psoriasis. In vitro and in vivo experiments have demonstrated that *Hypericum perforatum* extract can significantly improve imiquimod (IMQ)-induced psoriasis-like skin lesions (erythema, scaling, and skin thickening) in mice and reduce PASI scores. Its mechanism of action differs from single-target biological agents; instead, it simultaneously regulates the IL-23 / IL-17 inflammatory axis, corrects Th17 / Treg immune imbalance, and inhibits abnormal activation of the NF-κB signaling pathway, demonstrating the advantages of multi-component, multi-target synergistic effects of natural drugs. Furthermore, *Hypericum perforatum* is a unique plant resource in my country with a wide distribution. Compared to expensive biological agents, this invention has a significant cost advantage and is expected to be developed into a more affordable and accessible anti-psoriasis drug.

This invention relates to the field of biomedical technology, and more particularly to a polycyclic isopentenylcyclopentanone compound, its preparation method, and its application. The polycyclic isopentenylcyclopentanone compound provided by this invention has the structural formula shown in Formula 1. Using dried fruit of *Hypericum perforatum* as raw material, the extract is obtained through percolation extraction and concentration, and then suspended in water to obtain a suspension.
