Scientists unlock vitamin E potential in St. John's wort plants
Scientists at the Institute of Horticulture are exploring new ways to produce vitamin E from plants. Their latest research focuses on St. John's wort, a flowering plant known for its potential health benefits. The project aims to develop a dietary supplement using natural extracts from the plant.
The team grew 40 different species of St. John's wort to identify those with the highest vitamin E levels. After testing, four species showed the most promise for large-scale production. Researchers also found that greenhouse conditions boosted the plant's vitamin E concentration.
The project has already created a prototype product using extracts from St. John's wort. The goal is to refine this into a dietary supplement in the future. Alongside this, the institute is studying other sources, including monocotyledons like bran, to expand vitamin E production options.
Vitamin E is valued for its antioxidant effects, which help protect the body from harmful free radicals. The team is also working on extraction methods that are both efficient and kinder to the environment.
The findings suggest St. John's wort could become a practical source of vitamin E. If successful, the supplement could offer a natural alternative to synthetic versions. The institute plans to continue testing and refining the process in the coming years.
