Numerous studies have proven the preventive and therapeutic properties of many mushroom species on
various diseases
Owing to their widespread use in traditional medicine of east-Asian countries, medicinal mushrooms have become
the focus of extensive scientific research
INTRODUCTION
![Page 3: Mushrooms also provide a significant content of bioactive compounds mineralsvitaminspolyphenols Consumption of mushrooms contributes human diet lipidsdietary](https://reader038.vdocument.in/reader038/viewer/2022110116/551c23a2550346b24f8b5d20/html5/thumbnails/3.jpg)
Due to the diversity of mushrooms species, chemical composition and the content of phytochemicals in different mushrooms differ significantly
In order to enable their further use in medicinal purposes, there is a need for an characterisation of bioactive substances in medicinal mushrooms
Therefore, the scope of this study was to determine polyphenolic and polysaccharide content in products based on medicinal mushrooms, as well as their antioxidant capacity

CONCLUSIONS
1.)
• Products based on medicinal mushrooms show relatively high content of polyphenolic compounds, with the highest content of total polyphenols and total flavonoids measured in Agarikon +
2.)
• Antioxidant capacity of mushroom based products showed very high correlation to the both total polyphenol and total flavonoid content
3.)
• The highest content of soluble carbohydrates was detected in Agarikon.1 and Mycoprotect.1 suspensions
4.)• Based on the obtained results,
analyzed products present a good source of bioactive compounds
