Chemical composition and bioactive properties of the wild edible plant Raphanus raphanistrum L

Abstract

Recently, there has been an interest regarding the consumption of wild edible plants in modern diets. However, there is still scarce information about several wild vegetables traditionally consumed. Therefore, this work aims on documenting the nutritional and chemical composition of wild radish (Raphanus raphanistrum L.), as well as its bioactive potential. Results showed that wild radish is a potential source of beneficial compounds, including vitamin E, polyunsaturated fatty acid (particularly α-linolenic acid) and different phenolic compounds, in which fourteen phenolics were identified, with kaempferol-3,7-O-di-rhamnoside being the most abundant. The bioactive potential was exploited using hydroethanolic and decoction extracts. Both proved to inhibit several Gram-positive and Gram-negative bacteria and revealed antioxidant activity, while cytotoxicity against nontumor cell was not observed. In general, results evidence the interest in recovering the use of this wild vegetable as part of a varied diet, which can bring several health benefits.

Study and evaluation of antimicrobial activity and antioxidant capacity of dry extract and fractions of leaves of Raphanus sativus var. oleiferus Metzg.

“…Generally, radishes are characterized by a high content of phenolic compounds, including the flavonoids quercetin and kaempferol (SHIN et al, 2015;PARK et al, 2016;RICARDO et al, 2018;IYDA et al, 2019). Other compounds such as, alkaloids, glycosinolates, pigments and proteoglycans may also be present and exhibit antimicrobial, antioxidant, antitumor and antiviral activities (ARUNA; YERRAGUNI; RAJU, 2012;SHIN et al, 2015).…”

“…This may explain the resistance of these microorganisms to hydroethanolic extracts. However, several studies have demonstrated the antimicrobial capacity of different extracts of the plant against some of these microorganisms (SHUKLA et al, 2011;AHMAD et al, 2012;UMAMAHESWARI;AJITH;ASOKKUMAR, 2012;JANJUA;SHAHID;ABBAS, 2013;CHIHOUB et al, 2019;DUY et al, 2019;IYDA et al, 2019), suggesting that future experiments with extracts of the fodder turnip of different polarities are promising.…”

“…Chromatographic separation was performed on a Zebron-Kame column (30 m × 0.25 mm i.d., 0.20 µm film thickness, Phenomenex, Torrance, CA, USA). The operating conditions were previously described by Iyda et al [ 28 ]. The identification was made by a chromatographic comparison of the retention times of the sample FAME peaks with those of the standard 47885-U.…”

“…The analysis was performed in a DANI gas chromatograph GC 1000 (DANI instruments, Contone, Switzerland) equipped with a split/splitless injector and a flame ionization detector (FID) at 260 • C. Chromatographic separation was performed on a Zebron-Kame column (30 m × 0.25 mm i.d., 0.20 µm film thickness, Phenomenex, Torrance, CA, USA). The operating conditions were previously described by Iyda et al [28].

“…× 0.20 µm film thickness, Phenomenex, Torrance, CA, USA). The oven temperature program was as follows: the initial temperature of the column was 100 °C, held for 2 min, then a 10 °C/min ramp to 140 °C, 3 °C/min ramp to 190 °C, 30 °C/min ramp to 260 °C, held for 2 min [18]. The carrier gas (hydrogen) flow rate was 1.1 mL/min, measured at 100 °C.…”
