The tuber of Liriope platyphylla was extracted with 80% aqueous MeOH and solvent-fractionated with EtOAc, n-BuOH and $H_2O$. Evaluation of growth inhibitory activity of each fractions on various carcinoma cells, A549, SK-OV-3, SK-Mel-2, XF-498 and HCT-15, indicated the n-BuOH fraction to be the highest in the activity. From the fraction, two saponin compounds were isolated through Amberlite XAD-II and silica gel column chromatographies, repeatedly, and their chemical structures were elucidated as spicatoside A and B by interpretation of spectral data, NMR and IR, and adaptation of acid hydrolysis. Spicatoside A showed growth inhibitory activity on carcinoma cells, and the $IC_{50}$ values against A549, SK-OV-3, SK-Mel-2, XF-498 and HCT-15 cells were determined to be 17.3, 21.7, 14.9, 18.8 and $15.6\;{\mu}g/ml$, respectively.

The objective of this study was to compare the compositions and immuno-enhancing effects of 6-year-old red ginseng powder (RGP) with those of its fractions. RGP was subjected to extraction with 100% ethanol to obtain an ethanol fraction (E) and residue 1 (R1). Then, R1 was subjected to extraction with distilled water to obtain water fraction (W) and residue 2 (R2). Chemical compositions were as follows: 4.94% acidic polysaccharides and 1.56% ginsenosides (amounts of Rg1, Re, Rf, Rg2, Rb1, Rc, Rd, and Rg3) in RGP, 0.11% acidic polysaccharides and 6.99% ginsenosides in E, 4.93% acidic polysaccharides and 0.40% ginsenosides in R1, 0.50% acidic polysaccharides and 0.30% ginsenosides in R2, and 7.46% acidic polysaccharides and 0.61% ginsenosides in W. Immuno-enhancing effects of fractions from RGP were examined based on suppression of immune responses by cyclophosphamide. In the first fraction test, the antibody response to SRBCs increased significantly in the R1-treated group, but not the E-treated group. In the second fraction test, W showed higher immuno-enhancing effect than R1 and R2. W, which contained the highest amount of acidic polysaccharides, restored numbers of T and B cells, macrophages, as well as $CD4^+$ and $CD8^+$ T cells in the spleen suppressed by cyclophosphamide. These results suggest that acidic polysaccharides from red ginseng may be more effective than saponin in enhancing immune functions and reducing immunotoxicity of cyclophosphamide.

To investigate the effect of ginseng saponin fractions (total saponin, diol saponin and triol saponin) on the antibody production and on the recovery of immunosuppression in mouse, chick ${\gamma}$-globulin was used as immunogen and CY(cyclophosphamide) as immunosuppressive drug. The effect of ginseng saponin fractions on the production of total serum protein was investigated also. Circulating antibody was measured with ELISA method. Total saponin, dial saponin and triol saponin resulted 4 times higher titer values compared to control group in the production of antibody but resulted no effect on the recovery of immunosuppression induced by CY. From the above results ginseng saponin fractions are believed to effect on intact immune system and to promote antibody production by helping the cooperations among lymphocytes or the growth of lymphocytes. And the increase of total serum protein has no direct relations with the increase of circulatory antibody.

For the determination of anti oxidative effects of Korean red ginseng extracts, 100 mg/kg body weight of paraquat(1,1-dimethyl-4,4-bipyrimidinium dichloride) was injected to peritoneal cavity of 6 weeks 23-27 g of ICR mail mice which were pretreated with 200 mg/kg body weight of korean red ginseng extracts(total saponin, water extracts, alcohol extracts, lipophilic extracts) and ascorbic acid for 5 days. Most of mice died of paraquat toxicity within 4 days except only $30\%$ of ascorbic acid group. The hepatic total-SOD activity in liver was highest in ascorbic acid group and lipophilic ginseng extracts group next (p<0.0l). The level of hepatic hydroperoxide was lowest in the order of in alcohol extracts group, lipophilic extracts group and ascorbic acid group (p<0.0l). The highest catalase activity was induced by ascorbic acid followed by water extracts and lipophillic extracts (p<0.01). Finally, the lipid peroxidation level (malondialdehyde:MDA) was the lowest in water extracts group and ascorbic acid next (p<0.01). The highest MDA level was appeared in praquat group and next total saponin group next. In conclusion, the order of effectiveness of antioxidants was found to be ginseng water extracts> ascorbic acid> lipophillic extracts> other ginseng extracts. It was also found that any predominant antioxidant was not effective evenly to all of antioxidant test.

When the contents of the constituents such as total amino acids, free amino acids, volatile organosulfuric compounds and steroidal saponins among three origins in the aerial-and underground parts of Allium victorialis, it was suggested that the characteristic components regarding to quality evaluation could be differed according to the purpose of utilization. For the utilization of amino acids, underground parts of this plant was shown to be better than aerial part. In addition, Ulung island origin was found to contain the highest amino acids content among the three origins though the difference was small. The amino acids showing remarkably high contents were appeared to be arginine, glutamine and asparagine. In the volatile organosulfuric compounds, the origina of Mt. Odae and Mt. Chiri positioned in inland showed higher contents than Ulung island origin geographically positioned in the ocean. Inland origins were shown to contain higher organosulfurie component contents in aerial parts than in underground parts while those of Ulung island origin were higher in underground parts than aerial parts. Underground parts, regarding to saponin constituents, showed higher contents than aerial parts. Underground parts of Ulung island origin were shown to contain more saponins than those of other two origins and the sequence of the contents was in the order of Ulung island>Mt. Chiri>Mt Odac.

This study was conducted to select the optimal extraction method of codonopsis lanceolata saponin. To investigate the lancemasides content depending on each extraction method, various extractions were performed: reflux (methanol and butanol), hot water, as well as ultrasonic bath (40 kHz; continuous irradiation/interval irradiation) and ultrasonicator (20 kHz) extractions. From the result, the overall lancemasides content were the highest in ultrasonic bath (MeOH; continuous irradiation) extraction, followed by ultrasonic bath (water; continuous irradiation)>ultrasonic bath (MeOH; interval irradiation)>ultrasonicator (MeOH)>hot water>MeOH reflux>BuOH reflux extractions in that order. Sample drying method prior to ultrasonic bath extraction was more effective shade drying than freeze drying. Effective duration and temperature of extraction was 2 hr at $64^{\circ}C$. And ingredient change diverted from aster saponin Hb to lancemasides was identified by extraction condition such as extraction time and temperature.
