Toxohormone-L is a lipolytlc factor, found in ascites fluid of sarcoma 180-bearing mice and of patients with hepatoma. A substance that inhibited the lipolytic action of Toxohormone-L was isolated from Korean red ginseng powder. This substance had a pectin-like a-1,4-polygalacturonan backbone with some acetoxyl groups, and so was an acidic polysaccharide. Acidic polysaccharide was found to inhibit significantly toxohormone-L-induced lipolysis at its concentration of 10$\mu\textrm{g}$/ml.

This study was divised to observe an inhibitory toward a lipolytic action of toxohormone-L from large root and small root Nepal pseudo ginseng(NPG ; Nepal products) components by water extract and ethanol precipitate in vitro. Toxohormone-L Is known to be a lipolytic factor that was partially purified from the ascites fluid of sarcoma 180-hearing mice and of patients with hepatoma. The inhibitory effect that inhibited the lipolytic action of toxohormone-L by ethanol precipitate component of large root NPG(mean 46.8%) was higher (mean 1.8 times) than that of water extract component in final reaction concentration ,5001g1m1, on the other side inhibitory effect of water extract component in small root NPG(mean 43.9%) was higher(mean 1. 2 times) than that of ethano1 precipitate component, respectively. In a way inhibitory effect of ethanol precipitate component in large root NPG(47.6%), when final reaction concentration of sample were 1,000 U g/ml, was about 4095 lower than that of Korean red ginseng, respectively.

This study was divised to observe an Inhibitory effect toward a lipolytic action of toxohormone-L from large root and small root Nepal pseudo ginseng (NPG ; Nepal products) components by water extract and ethanol precipitate in vitro. Toxohormone-L is known to be a lipolytic factor that was partially purified from the ascites fluid of Sarcoma 180-bearing mice and of patients with hepatoma. The inhibitory effect that inhibited the lipolytic action of toxohormone-L by ethanol Precipitate component of large root NPG (mean 55.5%) was higher (mean 1.37 times) than that of water extract component in final reaction concentration of 500 and 1, 000ug/ml, on the other side inhibitory effect of water extract component in small root NPG (mean 55.5%) was higer (mean 1.14 times) than that of ethanol precipitate component. In a way inhibitory effect of precipitate component In large root NPG(47.6%), when final reaction concentration of sample were 1, 000ug/ml, was about 40% lower than that of Korean red ginseng.

This study was devised to observe the inhibitory effect of 7 kinds PG(PG1, PG2, PG3, PG4, PG5, PG6 and PG7) and of 5 kinds PG4(PG41, PG42, PG43, PG44 and PG45) of the acidic polysaccharide fraction from Korean red ginseng on a lipolytic action of Toxohormone-L. Toxohormone-L is a lipolytic factor, found in ascites fluid. of sarcoma-180 bearing mice and of patients with hepatoma. A substance that inhibited the lipolytic action of toxohormone-L was isolated from red ginseng powder. This substance was an acidic polysaccharides In vitro test showed that the inhibitory effect of PG4 and PG43 fraction of the lipolysis by Toxohormone-L was highest percent among other treatments at concentration of 50, 100, 200, 500 and 1,000ug/ml of reaction mixture. And total inhibitory activity(units) of PG1 and PG4, and PG4 s was highest among other treatments at the same concentration.

This study was devised to observe the inhibitory effect of 7 kinds of the acidic polysaccharide fraction(PGI, PGa, PG3, PGa, PGs, PG6 and PG7) from Korean white ginseng on a lipolytic action of Toxohormone-L. Toxohormone-L is a lipolytic factor, found in ascites fluid of .sarcoma -180 bearing mice and of patients with hepatoma. A substace that inhibited the lipolytic action of Toxohormone-L was isolated from white ginseng powder. This substance was an acidic polysaccharides. In vitro test showed that the inhibitory effect of PGs fraction of the lipolysis by Toxohormone-L was highest percent among other treatments at concentration of 50, 10, 200, 500 and 1,000 Ug/ml of reaction mixture. And total inhibitory activity(units) of PGI and PG4 was highest among other treatments at the same concentration and that of 10 Ug/ml.

Toxohormone-L is a lipolytic factor, found in ascites fluid of sarcoma 180-bearing mice and of patients with hepatoma A substance that inhibited the lipolytic action of Toxohormoue-L was isolated and purified from Korean red ginseng powder. This substance had a pectin-like $\alpha$-1,4-polygalacturonan backbone with some acetoxyl groups, and so was an acidic polysaccharide It inhibited Toxohormone-L Induced liploysis in a dose dependent manner at concentrations higher than 10 Ug/ml. Purified acidic Polysaccharide yield(PG4-3 and PG4-4 fraction) was about 0.03%. And also pectic acid that inhibited the lipolytic action of Toxohormone-L.

This study was devised to observe the inhibitory effects of 3 kinds of petroleum ether extracts (percolation by petroleum ether) from Korean red ginseng, Chinese red ginseng and American white ginseng on a lipolytic action of Toxohormone-L which has been known as lipolytic and anorexigenic factors. Toxohormone-L was obtained by partial purification of the ascites fluid from mice which had been Inoculated with sarcoma-180. The yields of petroleum ether extract from Korean red ginseng, Chinese red ginseng and American white ginseng were 0.64, 0.47 and 0.58 and respectively, indicating that the yield of Korean red ginseng was the highest. In vitro, at the concentration of 2 mg /ml, the inhibition rate of lipolysis by the petroleum ether extract of Korean red ginseng, Chinese red ginseng and American white ginseng were 55.1, 50.0 and 44.9% respectively, and the total inhibitory activity per gram of ginseng material were 18, 12 and 13 unit respectively, indicating that the Korean red ginseng was the most effective in the inhibition of the lipolysis.

Effect of an acidic polysaccharide fraction In Korean white and red ginseng on lipolytic action of Toxohormone-L was studied. Crude acidic polysaccharide fraction was extracted from main and lateral root of Korean white and red ginseng separately and purified several times. Inhibitory effect of crude polysaccharide fraction was determined by unit (1 unit is loft inhibition rate per Is sample). Yields of purified crude polysaccharide fraction of main and lateral root of red ginseng were 2.9 and 2.2 times higher than those of white ginseng, respectively. Inhibitory effects of main root of white and red ginseng, 11.hen final reaction concentrations of sample were 50, 100, 200, 500 $\mu$g/ml, were 37.2가 and 23.7% higher than those of lateral root of white and red ginseng. Inhibitory effect of main root of red ginseng was 2.3 times higher than that of white ginseng.
