A statistical analysis of saponin contents in various parts of raw red ginseng was studied. Saponin contents in main lateral and fee roots showed highly significant differences each other. Saponin contents in raw red ginseng had highly negative correlation with the root diameter (r= -0.926**). The estimation of saponin contents at mixing ratios of parts of root appeared to be possible.

This study was carried out to isolate saponin compounds from red-ginseng efflux, which was produced during the industrial processing of red-ginseng from fresh ginseng. We isolated crude saponin from the efflux extract (moisture content 35.0%) by using Diaion HP-20 adsorption method. Non-saponin fraction, which was adsorbed on Diaion HP-20 resin, was removed by eluating with $H_{2}O$ and 25% spirit. Then crude saponin was eluated with 95% spirit, continuously. Saponin in the eluated fractions was confirmed by TLC analysis. Crude saponin isolated from red ginseng efflux extract contained 12.10% of saponin. whereas those of white ginseng and red-ginseng were 3.30 and 3.39%, respectively. Ginsenoside contents showed the highest contents kin crude saponin from red ginseng efflux extract. Expacilly, the ginsenoside-$Rb_{1}$ and Re showed the highest contents in red-ginseng efflux extract when compared with those of white ginseng and red ginseng crude saponins. And the other ginsenosides except ginsenoside-$Rb_{1}$ and -Re also showed the highest contents in red ginseng efflux extract. However, the ratio of PD saponin (Panaxadiol saponin: $Rb_{1}+Rb_{2}$+Rc+Rd) to PT saponin (panaxatriol: $Re+Rg_{1}$) showed almost the same level when compared with those of ginseng saponin fractions. Ratio of PD/PT from red ginseng efflux extract was 1.99. Ratios of PD/PT from white ginseng and red ginseng were 1.85 and 1.84, respectively. Saponin purity, which was calculated by ratio percent of total ginsenoside to curde saponin content, was 45.90%. In case of white ginseng and red ginseng, the purities were 35.50 and 36.00%, respectively. However, by PHLC analysis, we confirmed that crude saponin isolated from red ginsengs. It suggested that crude saponin isolated from red ginseng ellux also would be useful component as ginseng saponins.

The saponins are considered the main effective components in Platycodon grandiflorum (Jacq.) A. DC.. In order to obtain the basic information for producing the high quality medicinal plant and processing, the crude saponin contents were analyzed with platycodi radix, the root of Platycodon grandiflorum by different cultivating years, parts, harvesting times and drying methods. The crude saponin contents were decreased by increasing cultivating years. The crude saponin contents were 2.74% in tail of root and 1.65 % in head of root, respectively. Besides, the contents of the crude saponin in cortex were 1.8 times more than that in core of root. The crude saponin contents in different harvesting times were 2.82% and 2.74% at March 10 and December 10, showing higher than that being harvested at June 10 and September 10. The crude saponin contents among drying methods were not significantly different at 5% level DMRT, but the hot air drying after steam showed the least crude saponin.

Optimum condition for cultivation of Anemarrhena asphodeloides B$_{UNGE}$ and seasonal variation of saponin and sapogenin contents in the rhizome were investigated. It is confirmed that the best harvest time is 3rd year. Average contents of saponin in rhizome was 8.5% and 5.0%, in fibrous roots, being highest in winter. The facotrs of saponin content variation were seemed to be temperature and humidity. It was also proved that asphonin was the mixture of timosaponin A-III, timosaponin A-I and mangiferin. Mangiferin and isomangiferin were isolated from the flower.

This study was attempted to observe the effect of crude ginseng saponin on the cell growth, lipid contents of Rhodotolula glutinis cells and fatty acid composition of the lipids from the yeast. The results obtained were as follows; The weight of dry yeast cells was increased by the addition of ginseng saponin and was noticeably increased in the treatment containing 10$^{-2}$ ％ ginseng saponin. With the increase of ginseng saponin concentration, lipids contents in Rhodotorula glutinis were increased but it's contents were decreased at the concentration of 10$^{-1}$ ％ ginseng saponin. The crude lipids of Rhodotorula glutinis were identified to be composed of palmitic, stearic, oleic, linoleic acid. Un-saturated fatty acid contents were greater than those of saturated fatty acids. Fatty acid contents were increased in the order of oleic, linoleic, palmitic and stearic acid, but palmitic acid was increased more than linoleic acid in the lipids of cells obtained at the higher than 10$^{-2}$ ％ ginseng saponin. As the ginseng saponin concentration was increased fatty acid contents were also increased, while they were considerably decreased in case of the addition of 10$^{-1}$ ％ ginseng saponin concentration.

We extracted and analysed the saponin fraction in the shoot of Aralia Elata. The results were as follows. 1. Natural samples had higher contents and more kinds of saponin than those grown in the green-house. The contents and the kinds of saponin decreased by steam treatment in both samples while the contents increased with the growth. The number of saponins in the natural raw sample (Nr2) which was at the most suitable stage for use was 37. 2. The saponin pattern of Nr2, with the large Fh saponin was specifically different from those with different harvest time which had large ‘d’ fraction. But all the natural samples which were steam-treated showed similar saponin patterns irrespective of harvest time. The saponin patterns of the green-house grown samples were simpler and showed less change during growing compared with those of the natural ones. All the steamed green-house grown samples showed the similar saponin patterns.

In order to investigate the optimal conditions which affects to extraction of ginseng extract and saponin in ginseng extract, experiment was carried out varing with ethanol percentage, extraction time, temperature, sol$.$vent and Plant Parts. The results art as follows: 1. The amounts of ginseng saponin was increased according to increanation of ethanol Percentage while the amounts of ginseng extract was decreased. 2. The amounts of ginseng extract was increased as the prolongation of extraction time, on the ether hand, ginseng saponin contents increased lentil 40hr. and decreased after that. 3. By the raise of extract temperature, both of the amounts of ginseng saponin and ginseng extract was increased two times and four times. respectively. 4. The total amounts ginseng extract was obtained 22.86u when the water used as the extraction solvent, 11.28% on ethanol and 11.04U on methanol, in the order. and the saponin contents gained when the extraction solvents of water, methanol and ethanol 7.47%, 12.36% and 12.77%, respectively. 5. It showed 9.23% of ginseng extract in epidermis and 8.4% of ginseng saponin in tail Part of raw ginseng and in the case of dried ginseng, ginseng extract and saponin showed the most amounts in epidermis of 18.28% and 19.35%, respectively. 6. The ratio of panaxadiol and panaxatriol contents of ginseng saponin was almost same when it was extracted varing with ethanol percentage and extraction time (duration), and the more alcohol percentage and the longer extraction time increased, the more fractional content of ginseng saponin was extracted.

In order to obtain the basic information for the development of ginseng varieties with high saponin contents. saponin contents and ginsenosides of Panax ginseng (Korean ginseng) and Panax quinquefolium (American ginseng) grown under the same environmental conditions were analysed. Crude saponin contents of root and aerial parts were more in Panax quinquefolium than in Panax ginseng, and aerial parts had more saponin contents in comparison with a root. Protopanaxatriol saponin was greatly more in the aerial parts of ginseng while more amount of protopanaxadiol saponins were detected in the root. As for the ginsenosides, the patterns of ginsenosides detected in total saponin of the aerial parts were not different between two species, Panax ginseng and Panax quinquefolium, but the root ginsenoside patterns were quite different. Ginsenosides such as Rg$_2$, R$_{f}$. R$_{a}$ and R$_{o}$ were not detected in the root of Panax quinquefolium (American ginseng).).).).

This study was carried out to obtain the basic information for non-saponin contents that can be used to index fresh ginseng roots (Panax ginseng C. A. Meyer) cultivated in the Republic of Korea and China. Non-saponin components in fresh gingeng roots which were cultivated in various areas and ages in Korea were determined. Acidic polysaccharide, total polysaccharide, crude polyacetylene were quantitatively analyzed by using the method of spectrophotometric determination, while the total protein was analyzed by using Lowry method. The results show that there were no statistically significant differences for the average contents of four non-saponins among 4-years-old, 5-years-old, and 6-years-old fresh ginseng roots. Additionally, this study assessed the average contents of non-saponin components in 4-years-old fresh ginseng roots (Panax ginseng C. A. Meyer) which were cultivated in Korea and China. The result showed that the average contents of crude polyacetylene and acidic polysaccharide were statistically significant. Four-years-old fresh ginseng roots cultivated in Korea had the higher average contents of crude polyacetylene and acidic polysaccharide than those cultivated in China. However the average contents of total polysaccharide and total protein had no statistically significant difference.

Crude saponin and ginsenosides in commercial white ginsengs such as six kinds of whole ginsengs, five kinds of tail roots and one undergrade raw ginseng were analyzed. The contents of crude saponin and ginsenosides in whole ginsengs were found to be 2.7 to 4.6% and 1.0 to 1.7%, respectively. On the other hand, those of tail roots were 3.3 to 7.2% and 1.3 to 4.4%, respectively. The content ratio of PD to PT saponin in whole ginsengs showed a little variation as 0.73 to 0.92, while those of tail roots showed a greater variation in the range of 0.72 to 1.75, indicating that tail roots contain higher content of PD saponin than whole ginsengs did.
