-"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 chromatographymass spectrometry. The major components found in the oil of all leaves were phytol (65.369.7%), hexadecanoic acid (2.514.3%), methyl linolenate (2.111.1%) and (Z)-3-hexen-1-ol (0.76.9%). Corresponding aliphatic or aromatic glucosinolate compounds identified in the leaves constituted only 0.35.7% of the isolated volatiles. They were 5-(methylthio)-4-pentenenitrile (0.32.2%), 4-(methylthio)butyl isothiocyanate (0.31.7%), 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 (30.349.9%), 4-(methylthio)butyl isothiocyanate (17.925.7%), methyl linolenate (8.521.7%), 5-(methylthio)-4-pentenenitrile (1.56.9%), dimethyl trisulfide (1.13.8%), 5-(methylthio)pentyl isothiocyanate (0.52.0%), 4-(methylthio)-3-butenyl isothiocyanate (0.21.8%) and 2-phenylethyl isothiocyanate (0.11.5%)." \\+"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.

 "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)." \\ "Four compost treatments and an unamended control were compared for field production of eight (spring) or four (fall) red radish (Raphanus sativus L.) cultivars...

 +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. \\
