In the present study, an attempt was made to observe the effect of lipid components in pantocrin and antler velvet and sponge layers extracts on the aldolase activity in the rat spinal nerves. The antler chloroform-methanol (2:1) extracts are known to be composed of neutral lipids, cholesterol, cerebrosides, spingomyelin, phosphatidyl choline, phosphatidyl ethanolamine, phosphatidyl serine and gangliosides. The antler extracts were studied on the aldolase activity in the rat spinal nerves. The aldolase activity was measured by the method of Lehninger. To invesitigate the components of the extracts which affect the enzyme activity, the chloroform-methanol (2:1) extracts of antler were fractionated into petroleum ether soluble and insoluble fractions and their effects on the enzyme activity were compared. It was found that the chloroform-methanol (2:1) extracts of the antler sponge and velvet layers as well as those petroleum ether soluble fractions obtained from the chloroform-methanol (2:1) extracts, decrease the aldolase activity by 18~23%. However, pantocrin showed increasing effect on the aldolase activity by 42.6%. The petroleum ether insoluble fraction of the chloroform-methanol (2:1) extract showed no significant increasing activity (about 13%) on the spinal nerves aldolase. The components of pantocrin and the petroleum ether insoluble fractions were attempted to analysize by thin layer (silica gel) and gas liquid chromatography.
