The authors have already reported a method to separate catecholamines, serotonin, histamine and polyamines by a single P-cellulose column chromatography adsorption

(1, 2). As the

of histamine and polyamines to the column is significantly strong, the weak

acidic cation exchanger, CM-cellulose, was utilized to separate these amines and the method was successfully applied to rat tissues. CM-Cellulose (capacity: 0.70 meq/g) was obtained from Brown Co., U.S.A. Phosphate buffer (pH 6.2 and 7.5) was prepared from 0.1 M NaH2PO4 and 0.1 M Na2HPO4.

Borate

buffer (pH 9.0) was prepared from 0.2 M H3B03 (containing 0.2 M KCI) and 0.2 M Na2CO3. These buffers were diluted and NaCl was added at the time of application. buffers were used in the separation procedure.

The following

1 : 0.01 M phosphate buffer (pH 6.2), 2:

0.03 M phosphate buffer (pH 6.2), 3: 0.03 M phosphate buffer (pH 7.5), 4: 0.02 M borate buffer containing 0.05 M NaCI, 5: 0.02 M borate buffer containing 0.075 M NaCl, 6: 0.02 M borate buffer containing 0.15 M NaCl.

Wistar female rats (350-380 g) were decapitated

and each tissue was homogenized in 5 volumes of ice-cold 0.4 N HCIO4. was centrifuged at 3000 rpm for 5 min.

The homogenate

The supernatant was neutralized to pH 5-6 with

2 N KOH through a microtube with stirring in an ice bath, and the precipitate was removed by centrifugation (3000 rpm, 5 min).

The neutralized tissue extract (1-4 nil) was applied

to a CM-cellulose column (0.6 x 10 cm) equilibrated with buffer-l.

The elution was per

formed at room temperature (20-25'C) by increasing stepwise both concentration and pH of the buffer (buffer-l to 6).

Histamine and polyamines were determined by OPT-reaction

and TNBS-reaction, respectively, as described previously (1). The standard substances showed the following separation in the CM-cellulose column chromatography. Fraction

The separation and the recovery of histamine, spermidine and spermine were complete (recovery: 95-100%). The substances interfering with the fluorometric determination of histamine such as arginine, agmatine and spermidine (3) were removed from the histamine fraction.

After washing with buffer-1 (15 ml) and buffer-2 (15 ml), histamine, spermidine and spermine were eluted stepwise by exchanging the elution buffers.

The present values of polyamines for the brain are higher than those

in our previous experiment using a P-cellulose column (1).

This can be explained by the

fact that there was a miss in calculation in so far as one molar spermidine phosphate con taining two molars of spermidine was accounted for as one molar spermidine. value of absorbance of spermidine at 420 mn in the TNBS-reaction

Thus, the

reported previously

(2) is double the true value. Another reason is that the cerebellum had been removed from the brain in the previous experiment. The cerebellum contains the highest polyamine level of all brain regions (6).

When using the whole brain, both methods (CM-cellulose and

P-cellulose column chromatography)

showed the same levels of polyamines.

In comparison with P-cellulose column chromatography,

the present method has the

advantage of a rapid separation of histamine, spermidine and spermine. REFERENCES 1) ENDO,Y. ANDOGURA,Y.: Europ. J. Pharmacol., 21, 293 (1973); 2) ENDO,Y. ANDOGURA, Y.: Japan. J.
