- Ellagitanins ( gallic acid , pentagalloylglucose , hamamelitanin )
- Catechic tannins ( catechin , gallocatechin , epicatechin , epigallocatechin ), proanthocyanidols , procyanidols , procyanidol - prodelphinidol copolymers
- Flavonoids : flavonol glycosides ( astragaloside , myricitroside , isoquercitroside ), kaempferol and quercetol glycosides

Properties
Plant properties
- Vasoconstricteur
- Antiphlogistic and anti-inflammatory [1] , [2]
- Bacteriostatic and molluscicidal, certain hamamelitanin derivatives potentiate vancomycin in the treatment of infections resistant to Staphylococcus aureus (MRSA) by action on the biofilm [3] , [4] , inhibition of Quorum Sensing (molecular signals regulating the density of a bacterial population) by hamamelitanin [5]
- Protector of vascular endothelium, hamamelitanin inhibits TNF-mediated endothelial cell death without modifying endothelial adhesiveness, anti-hemorrhagic activity, protective agent against UV radiation [6] [7]
- Tonic
- Astringent (property of tightening the tissues)
- Action on varicosities (alterations of the fine and superficial vascular wall, at the interface between the arterial and venous network, often red or bluish)
- Reduces UVB-induced erythema [8]
- Antimutagenic [9]
- Anti-radical and antioxidant [10] , [11]
