RESUMO
A pot experiment was conducted with the objectives to assess the adaptation potential of fennel crop grown at 10, 20, 25, 35 and 40 ESP (exchangeable sodium percentage) levels. Results showed that the rate of seed germination, plant growth including branching pattern, umbels per plant and 1000 test seed weight were adversely affected by sodic soils. Assuming that fifty percent reduction in seed yield and Na+/K+ ratio in leaf tissue as an index of alkali tolerance revealed that fennel was tolerant up to 25 ESP. The cell sap pH and EC reflected optimum osmoticum maintenance to withstand sodicity stress at this level and beyond this leaf water potential decreased (negatively) more to impede water uptake.

Cardiospermum halicacabum extracts have been evaluated for their antipyretic activity against yeast-induced pyrexia in rats. The ethanol as well as n-hexane extracts (400 mg/kg) of the whole plant powder showed potent antipyretic activity. The water extract was devoid of significant activity. The antipyretic activity of the ethanol extract was concentration dependent.

Trichopus zeylanicus extract has been evaluated for its antihepatotoxic and choleretic activities in rats. The plant leaf suspension (1000 mg/kg; wet weight) as well as its methanol extract (100 mg/kg) showed a remarkable hepatoprotective activity against paracetamol-induced hepatotoxicity as judged from the serum marker enzymes, liver histology and levels of lipid peroxides in liver. The effect of the methanol extract was found to be concentration dependent. The water and hexane extracts were almost inactive. The methanol extract (100 mg/kg) also exhibited choleretic activity in anesthetized normal rats. In short, we report here for the first time the antihepatotoxic as well as choleretic properties of T. zeylanicus.
