Anthocyanins are the most abundant type of flavonoid [1] and they are responsible for the blue or purple color present in blueberries, cherries, grapes, blackberries and others[2]. Actually a little bit more than 500 anthocyanins have been found [3] in different herbs, plants and natural sources.

Baicalein is a phenolic flavonoid compound [3,13], a flavone extracted from the roots of Scutellaria baicalensis [13], Scutellaria paniples and Oroxylum indicum. Phenolic compounds are the largest group of plants secondary metabolites [4]. They are known for their many beneficial properties and health-promoting characteristics, most of those mainly exerted by its antioxidant and free-radical scavenging distinctive properties. Polyphenolic compounds have also reported an anti-ulcerogenic activity and a good level of gastric protection [4].

Carvacrol also known as cymophenol, (C6H3CH3(OH)(C3H7)); Present in Thymus vulgaris, Carum copticum, origanum and oregano essential oils [3], Carvacrol is a monoterpenic phenol that has been referenced in several clinical trials and scientific research studies as a powerful antibacterial agent against pathogenic fungi, yeast and bacteria as well as human, animal and plant pathogenic microorganisms including drug-resistant and biofilm forming microorganisms [1,2].
