The genus Scutellaria L. (Lamiaceae family) includes about 350 species [6], occurring in Europe, the United States and East Asia. Scutellaria (Scullcap) species have been used in folk medicines in different parts of the world for the treatment of hyperlipidemia, allergy, arteriosclerosis, hepatitis, and hypertension for hundreds of years [7]. Many Scutellaria species have been, also, used as culinary herbs, and for ornamental purposes. Because of having a wide range of pharmacological actions, numerous members of Scutellaria genus are very important as medicinal plants. More than 295 chemical compounds have been identified in the species of the genus Scutellaria, mainly flavonoids and diterpenes [3]. Scientific research has shown that the active compounds in some species of Scutellaria have multiple therapeutic effects: antiviral, antimicrobial, antibacterial, hepatoprotective, spasmolytic, antidiarrheal, antifungal, antipyretic, antioxidant, antiinflammatory, anticonvulsant [3, 7, 11, 12]. Recently, the genus Scutellaria has gained considerable interest concerning anticancer activities. The present study has been focused on seven taxa, representatives of the genus Scutellaria (S. baicalensis Georgi, S. altissima L., S. albida L., S. albida ssp. colchica (Rech. f.) Edmond., S. supina L., S. orientalis L. and S. alpina L.) grown in the collections of “Al. Ciubotaru” National Botanical Garden (Institute) (NBGI).
