-"Varieties of radish are now broadly distributed around the world, but there are almost no archeological records available to help determine its early history and domestication. However, scientists tentatively locate the origin of Raphanus sativus in southeast Asia, as this is the only region where truly wild forms have been discovered... The most commonly eaten portion is the napiform taproot, although the entire plant is edible and the tops can be used as a leaf vegetable. The seed can also be sprouted and eaten raw in a similar way to a mung bean." \\

+"White Radish, or daikon (Raphanus sativus) is a popular root vegetable in East Asian countries... The Japanese processing white radish cultivar, Hoshiriso, was grown in spring, summer, autumn and winter on the Central Coast of New South Wales, Australia and accumulation of the characteristic pungent flavour component, [[http://www.thegoodscentscompany.com/data/rw1035801.html|4-methylthio-3-trans butenyl isothiocyanate]] (MTBITC) during growth was determined.

+"The volatile constituents from the leaves and roots of Raphanus sativus var. black, white and red were isolated by hydrodistillation in a Clevenger-type apparatus and were analysed by gas chromatography and gas chromatography-mass spectrometry. The major components found in the oil of all leaves were phytol (65.3-69.7%), hexadecanoic acid (2.5-14.3%), methyl linolenate (2.1-11.1%) and (Z)-3-hexen-1-ol (0.7-6.9%). Corresponding aliphatic or aromatic glucosinolate compounds identified in the leaves constituted only 0.3-5.7% of the isolated volatiles. They were 5-(methylthio)-4-pentenenitrile (0.3-2.2%), 4-(methylthio)butyl isothiocyanate (0.3-1.7%), 2-phenylethyl isothiocyanate (0.4%), 4-(methylthio)-3-butenyl isothiocyanate, 4-methylpentyl isothiocyanate, benzyl isothiocyanate and benzenepropanenitrile. The major components in the oil of all roots were hexadecanoic acid (30.3-49.9%), 4-(methylthio)butyl isothiocyanate (17.9-25.7%), methyl linolenate (8.5-21.7%), 5-(methylthio)-4-pentenenitrile (1.5-6.9%), dimethyl trisulfide (1.1-3.8%), 5-(methylthio)pentyl isothiocyanate (0.5-2.0%), 4-(methylthio)-3-butenyl isothiocyanate (0.2-1.8%) and 2-phenylethyl isothiocyanate (0.1-1.5%)." \\

+"Four compost treatments and an unamended control were compared for field production of eight (spring) or four (fall) red radish (Raphanus sativus L.) cultivars... Samples of median-sized marketable storage roots were shredded and juice was analyzed in the laboratory for pungency as measured by isothiocyanate (ITC) concentration (primarily 4-methylthio-3-butenyl isothiocyanate). In the spring, mean ITC concentrations ranged from 28.2 to 36.8 μmol per 100 g juice in storage roots from the four compost treatments, and differences were not significant (α = 0.05)." \\

+The seeds of R.sativus contained 4-methylthio-butanyl derivatives like sulforaphene, sulforaphane, 5-(methylsulfinyl)-4-pentenenitrile, 5-(methylsulfinyl)-pentanenitrile, sinapoyl desulfoglucoraphenin, (E)-5-(methylsulfinyl)pent-4-enoxylimidic acid methyl ester, (S)-5-((methylsulfinyl)methyl)pyrrolidine-2-thione. The
+observed biologic activity supports the traditional use of the plant. Sinapoyl desulfoglucoraphenin showed good
+anti-neuroinflammatory activity through inhibition of NO production via suppression of iNOS expression in microglia - maybe useful for the development of novel neuroprotective agents. \\
