showed better percent recovery in both extraction techniques and was selected for extraction of analytes from the biological samples.
concentrations stay at current levels, then the delay in recovery would be only five years.
Different compositions of mobile phase of dichloromethane
and methanol (see Table 1) have been tried but didn't produce any better result.
Consistent with other chlorinated solvents such as trichloroethylene and tetrachloroethylene, exposure to dichloromethane
results in decreased motor activity, impaired memory, and changes in responses to sensory stimuli in mice and rats (reviewed by Bale et al.
ciliata stems, leaves and fruits did not reduce larval survival, but dichloromethane
fractions of leaves and fruits affected the larvae development (Table 2).
5 in the case of chloroform which is exactly the opposite of the results obtained with dichloromethane

The methanol extract (ME) possessed the highest antioxidant activity followed by the methanol-water (MW) extract and finally dichloromethane
extract (DCM) which showed the lowest potential.
The lasalocid contained in the aqueous methanol supernatant was extracted with 12 mL of dichloromethane
