# Heracleum sosnowskyi Manden. in the Context of Sustainable Development: An Aggressive Invasive Species with Potential for Utilisation in the Extraction of Furanocoumarins and Essential Oils

## TL;DR

Heracleum sosnowskyi is an invasive plant causing ecological harm but also has potential for extracting useful compounds like furanocoumarins and essential oils.

## Contribution

The paper explores the dual nature of H. sosnowskyi as both an invasive threat and a potential resource for bioactive compounds.

## Key findings

- H. sosnowskyi secretes furanocoumarins and essential oils with medicinal and industrial applications.
- The plant's invasive nature causes biodiversity loss and health risks due to its allelopathic and photosensitizing properties.
- Utilizing H. sosnowskyi biomass could help mitigate its ecological impact while supporting sustainable development.

## Abstract

Heracleum sosnowskyi Manden., or H. sosnowskyi, of the Apiaceae was first cultivated in the USSR in 1947 as a potential fodder plant. Due to the development of cold-resistant cultivars and the characteristics of H. sosnowskyi, it quickly became feral. As a result, H. sosnowskyi began to spread as an aggressive invasive species in the 1970s and 1980s. By the 90s it had become an ecological disaster. As well as forming monocultures and displacing native species, H. sosnowskyi contains furanocoumarins, photosensitizing compounds that increase skin sensitivity to ultraviolet rays and cause severe burns. In addition, furanocoumarins have cytotoxic, genotoxic, mutagenic and estrogenic effects. H. sosnowskyi also contains essential oils, which are particularly active during flowering and can irritate the mucous membranes of the eyes and respiratory tract, as well as cause allergic reactions in the form of bronchospasm in people with asthma and hypersensitivity. When released in high concentrations, these biologically active compounds have an allelopathic effect on native plant species, displacing them and reducing biodiversity. As H. sosnowskyi is not native; the biologically active compounds it secretes have a xenobiotic effect, causing serious damage to the ecosystems it occupies. However, in parallel with these negative properties, furanocoumarins have been found to be effective in the treatment of cancer and skin diseases. Furanocoumarins possess antimicrobial antioxidant osteo- and neuroprotective properties. Essential oils containing octyl acetate, carboxylic acid esters, and terpenes can be used in the pharmaceutical industry as antiseptic and anti-inflammatory agents. Additionally, essential oils can be used as biofumigants and natural herbicides. A comprehensive approach allows H. sosnowskyi to be viewed in two ways. On the one hand, it is an aggressive alien species that causes significant damage to ecosystems and poses a threat to human health. On the other hand, it is a potentially valuable natural resource whose biomass can be used within the principles of the circular economy. It is hoped that the use of H. sosnowskyi for economic interests can be a partial compensation for the problem of its aggressive invasion, which is of anthropogenic origin.
