Abstract
The present communication reports the comparison of in vivo antioxidant, antimelanoma and antimutagenic activities of Eruca sativa seed oil and its bio principles (allyl isothiocyanate, phenylethyl isothiocyanate and sulphoraphane) against B16F10 melanoma cells induced in C57BL/6 mice model. Among the various treatments considered for the study, isothiocyanates combination (allyl isothiocyanate, phenylethyl isothiocyanate and sulphoraphane; 1:1:1; 10 µM) exhibited optimum antioxidant activity, 51.95±1.14 µM glutathione per mg protein compared to seed oil 25.91±1.26 µM. Lipid peroxidation value was 9.97±1.72 µM malondialdehyde per mg wet weight for isothiocyanates combination against seed oil, 28.45±1.87 µM and rendered significant protection against oxidative stress induced by melanoma in liver tissue. Isothiocyanates combination significantly suppressed various parameters, such as tumor growth, isothiocyanates combination by 36.36% while the seed oil by 15.23%; tumor weight, isothiocyanates combination by 45.9% and seed oil by 19.6%; tumor volume, isothiocyanates combination by 41.7% while the seed oil by 32.3%, measured for antimelanoma activity at a concentration of 10 µM. Isothiocyanates combination has been found to be more cytotoxic bioagent against B16F10 melanoma cells induced in C57BL/6 mice compared to naturally occurring Eruca sativa seed oil.
