Turnip (Brassica Rapus L.): a natural health tonic

Abstract

In addition to basic nutrition, plant-based foods provide substantial amounts of bioactive compounds which deliver desirable health benefits. During the last decade, secondary metabolites, also known as phytochemicals, obtained from plants, have aroused special attention by researchers. Amongst such plants, the turnip contains a few valuable components which not only endorse health benefits but also provide healing properties. Various bioactive components, for example peroxidase, kaempferol, phenolic compounds, sulforaphane, organic acids, vitamin K, glucosinolates etc are highlighted in this manuscript. Likewise, numerous minerals, such as copper, manganese and calcium, and organic acids, such as sinapic and ferulic acids and their derivatives, found in different amounts in fresh greens and turnip roots, are also discussed briefly. The current paper is focused on the phenolic compounds, which act as beneficial compounds for human health and can be isolated from plant foods, especially turnip. Due to the presence of bioactive constituents, turnip imparts a positive role with respect to the hepatic injury caused by diabetes, high antioxidant activity and a good hepatoprotective role. The impact of environmental conditions and processing mechanisms on the phenolic compound composition of Brassica vegetables, with special reference to turnip, was also briefly discussed.

The value of bioactive compounds of cruciferous vegetables (Brassica) as antimicrobials and antioxidants: A review

“…Likewise, it is difficult to properly classify phytochemical because have differences in the origin, stage of development and composition of each Brassica group (Gómez-Gómez & Boller, 2000). In general, the phytochemicals as secondary metabolites (terpenoid, alkaloids, phenolic compounds, lignins, plants steroid, curcumines, saponins, flavonoids, glucosides), depending on their role in plant metabolism (Ferreira, Passos, Cardoso, Wessel, & Coimbra, 2018) are synthesized as defense system (Javed et al, 2019). In particular, the Brassica is rich in phytochemical compounds recognized as bioactive secondary metabolites naturally occur in these plants, have the capacity to act on diverse molecular targets into the cells.…”

A Critical Review on Phytochemical Profile and Biological Effects of Turnip (Brassica rapa L.)

“…Turnip leaves possess more nutrients compared with turnip roots. Besides the nutrients mentioned above, some researchers reported that turnip leaves are abundant sources of carotenoids, lutein, vitamin A, vitamin B, and vitamin K ( 22 ).…”

“…Both the roots and leaves have a pungent flavor and the edible portions of the turnip are used as an ingredient in stews and soups. Similarly, turnip tops and turnip greens have been used as vegetable products in some parts of the globe (Schonhof et al, 2007 andJaved et al, 2019).…”
