RESUMEN
Fresh hotbed chives solutions were extracted respectively by ether, acetic ether and n-butyl alcohol and protein constituents and non-protein constituents were obtained. Ether extractions (non-protein constituents) had the strongest antirriutagenic effects by the SOS chromotest Non-protein constituents of hotbed chives were analysed further by gas chromatography-mass spectrum and 30 chemical substances were isolated and identified. Their antimutagenic substances may be dimethyl disulfide, 4-methyl-2-pyridinethione, di-2-propenyl trisulfide, 3-(allylthio)-propionic acid.
RESUMEN
In the present paper, antimutagenic mechanisms of hotbed chives, fragrant-flowered garlic and garlic leaves were investigated by the SOS Chromotest The results showed that these vegetables could inhibit the SOS respones induced by temperature (42℃) in E coli GW1060 and GW11M (rec 441 (tif)), but they could not act on SOS network gene expression in E. coli GW2707 (lexA::Tn5), so one of their antimutagenic mechanisms is inhibitory effect on cleavage of lexA by RecA protease. Desmutagenic test results indicate that some aqueous extractions of the three vegatables can inactivate mutagens outside cells.
