2346 J. Med. Plants Res. Table 3. Brime shrimp lethality test of the essential oil of T. violacea rhizome. Concentration (µg/ml) Essential oil of T. violacea rhizome Average no. of survivors Average no. of dead Mortality (%) 2.5 15.0 ±0.00 15.0 ± 0.00 0 5.0 13.0 ± 0.00 2.0 ± 0.00 13.3 10.0 11.0 ± 0.00 4.0.0 ± 0.00 26.6 20 0 0 100 Control 15 0 0 LC50 = 12.59 µg/ml Data were expressed as mean ± SD. these studies showed that the oil extract of rhizome of T. violacea was cytotoxic and this toxicity is concentration dependant (Table 3). It was observed that all the nauplii survive at the lowest concentration (2.5 µg/ml). This significant lethality of the oil extracts(LC50values less than 100 µg/ml) against brine shrimps nauplii might be due to the presence of polysulfides which has be implicated as cytotoxic agents with potential anticancer, antimicrobial and antifungal activities (Münchberg et al., 2007; Anwar et al., 2008). The present study indicates that the essential oil of rhizome of T. violacea exhibit interesting biological activities such as antioxidant and cytototoxic effect and may serve as alternative natural source of anticancer, and antibiotic and antimicrobial agents.
