An equivalent extract
from 12.5 mg dried plant material per ml aqueous infusion was obtained.
The final assay concentrations were 10, 30, and 100 mg dry weight equivalent extract m [L.sup.-1].
The ethyl acetate fraction of the aqueous methanol extract at 100 mg dry weight equivalent extract m[L.sup.-1] completely inhibited the shoot and root growth of garden cress.
Present paper deals with dose dependent (0.5, 1.0, 1.5,2.5,3.5 g dry plant equivalent extract
/100 g body wt., p.o.) blood glucose lowering effect of aqueous extract of E.
A portion of the extract was diluted into small volume of methanol to prepare four assay concentrations 3, 10, 30, and 100 mg dry weight equivalent extract [mL.sup.-1] and then was added to a sheet of filter paper (number 2) in 28 mm Petri dishes.
The GP of all but lettuce showed a reduction trend at concentration greater than 30 mg dry weight equivalent extract [mL.sup.-1] (Figure 1).
