It is also interesting to note that, in Formulation 9, although the level of gel content was very low, no TMPTMA monomer had been extracted by diethyl ether
To isolate glucuronide metabolites, the urine residue described above was submitted to a nitrogen stream to eliminate the possible remaining traces of diethyl ether
and mixed with 2 mL of acetate buffer (2 mol/L, pH 5.
The product (UAN) was collected after precipitation in diethyl ether
, washed with diethyl ether
, and drying in vacuum.
The flask was cooled to -30 [degrees] C and a solution of fluorenyl lithium in diethyl ether
(prepared above) was added into it drop wise with stirring over a period of 45 min.
The dams were anesthetized with diethyl ether
and then sacrificed by exsanguination; the body weights and organ weights (liver, kidney, spleen, and thymus) were then recorded.
3] at 0[degrees]C, then extracted 5 times with diethyl ether
, filtered through a [K.
(3 mL) was added, and the aqueous phase was extracted by a combination of shaking and vortex-mixing for 1 min.

6 % ethanol and treated with 4-fold excess of diethyl ether
for decreasing the content of the dark brown matter by its precipitation from the solution, and then evaporated to dryness yielding 8.

5, and neutral compounds were removed by partitioning with 2 x 5 ml fresh diethyl ether
in a 20 ml glass vial.
100 ml of diethyl ether
was measured and mixed with the crude extract of the leaves stirred very well and then poured into a separating funnel, the mixture in the separating funnel was further shaken severally and allowed to settled down.
