Phytochemical screening of red cabbage (Brassica oleracea) powder and juice - A comparative study

Abstract

Cruciferous vegetables are one of the dominant food crops worldwide. Cruciferous vegetables are vegetables of family Brassicaceae (also called cruciferae). They are good source of many health promoting and potentially protective phytochemicals including folic acid, phenolics, carotenoids, selenium, glucosinolates and vitamin c. Incorporating these potent plant based compounds in daily food is a safe, effective and easily available way to guard against many of today’s most common diseases. The Red cabbage (Brassica oleracea) is cool season cruciferous vegetable. Present study was conducted to assess the qualitative phytochemical analysis of red cabbage powder and juice. The extract of powder and juice of red cabbage reveals the presence of many phytochemicals such as alkaloids, glycosides, flavonoids, saponin, tannin, steroids, terpenes and phytosterols. The compounds isolated from this vegetable possess very important biological activities including anti-diabetic, antioxidant, hypolipidemic, antihyperglycemic, Cardioprotective and Anti-cancer.
