“…Birds in 4 replicate pens received 0, 150, 300 and 450 ppm turnip extract in drinking water from days 1–42 based on a completely randomized design. Inclusion rates were based on a previous study of antimicrobial activity [ 14 ], in which the strongest inhibition of fungi was by turnip root extract included at 100 ppm, but it was noted that protective effects were dose dependent. Four replicate pens of a control treatment with no turnip extract but incorporating a Virginiamycin antibiotic at 200 g/tonne were also included, a high therapeutic dose rate to achieve maximum effect.…”

“…It is hoped that these will be stimulated by the positive results demonstrated by the medium level of turnip extract inclusion in our study. It is also possible that the doses selected were not optimal for antimicrobial effects in the gastrointestinal tract of chickens, but we based the doses on the only relevant study [ 14 ], in which different doses of turnip root extract were tested on fungal plates. We tested both higher and lower doses than the optimal dose derived from this experiment.…”

There are concerns about inclusion of antibiotics in the feed of broiler chickens, because of the development of antibiotic resistance, leading to a search for alternative feed additives. Turnip extract is known to have antibacterial properties but has not been tested in the diet of broiler chickens. We allocated 200 broiler chicks to receive one of four levels of turnip extract in their water, 0, 150, 300 or 450 ppm, or a standard antibiotic, Virginiamycin, over a 42-day growing period. Although initially there were detrimental effects of providing 450 ppm, overall the 150 ppm level of supplementation increased weight gain, compared with birds given Virginiamycin, and decreased gizzard weight. Birds given 150 ppm or Virginiamycin had increased low-density lipoproteins (LDLs) and reduced very low-density lipoproteins (VLDLs) in their blood serum and reduced antibody responses to sheep red blood cells, compared to birds in the 450 ppm treatment. Birds given turnip extract at 450 ppm had fewer Gram-negative lactose and coliform bacteria than those provided with no turnip extract, and those provided with 150–300 ppm had the same as those provided with Virginiamycin. Turnip extract could potentially replace antibiotics included in the feed of broiler chickens for growth promotion and the control of bacterial infection of the gastrointestinal tract.

“…The light petroleum fraction was revealed with strong antifungal activity against Candida albicans with an minimum inhibitory concentration (MIC) of 12.5 mg/mL (Beltagy, ). In addition, the turnip root showed the highest inhibition (45%) against Fusarium oxysporum , followed with turnip seed (35%) and turnip stem‐leaf (30%) (Fierro, Jiménez, & Coy‐Barrera, ). Another study suggested that 2‐phenylethyl isothiocyanate ( 21 ) could significantly inhibit Vibrio parahaemolyticus with a MIC of 100 μg/mL according to the antimicrobial investigation against three food‐borne pathogens, Vibrio parahaemolyticus , Staphylococcus aureus and Bacillus cereus (Hong & Kim, ).…”

Despite the advancement of medical science, diseases are part‐and‐parcel of human life. Plants have provided humans with medicines since time immemorial, and are still one of the primary sources for drug discovery. Brassica rapa L., commonly known as turnip, is one of the world's oldest cultivated vegetables. Besides being an important vegetable and source of oil, turnip is also used as a traditional medicine for the treatment of headaches, chest complaints, rheumatisms, oedemas, gonorrhoea, syphilis, and rabies. Glucosinolates and isothiocyanates (mainly 2‐phenylethyl, 4‐pentenyl, and 3‐butenyl derivatives) are the main constituents of turnip with diverse bioactivities, especially for the protective effect against cancers. Besides, flavonoids, phenolics, indoles and volatiles are also concomitant in this plant. Pharmacological investigation on turnip revealed the antitumor, antihypertensive, antidiabetic, antioxidant, antiinflammatory, hepatoprotective, and nephroprotective effects. The anticancer property was found to be the most promising biological activity of turnip with 2‐phenylethyl isothiocyanate, phenylpropionitrile, brassicaphenanthrene A, 6‐paradol, and trans‐6‐shogaol as the major active constituents. Flavonoids and phenolics with high free radical scavenging activity should be corresponding to the antioxidant effects. Arvelexin, an indole derivative in turnip, was reported with various effects involving antiinflamatory, antihypertensive and hypolipidemic potency. In spite of many studies concerning either the chemical constituents or the biological activities of turnip, only a few cases disclosed the active ingredients responsible for diverse bioactivities. This review summarizes the research progress on the chemistry and health‐benefits of turnip over the past 20 years to provide a reference for the further investigation.
