In this study, we investigeated the anticarcinogenicity of various types and ages of ginseng extracts as an extended study using Yun's anticarcinogenicity test. Fresh ginseng at 1.5, 3, 4, 5 and 6 years was dried and powdered. And white ginseng was processed in the same way that of fresh ginseng after removal fo the ginseng cortex and fine root. For red ginsneg, fresh ginseng was steamed and dried. Each ginseng powder was extracted and extracts was freeze dried. Newborn N:GP(S) mice were given a single subcutaneous injection of 0.5 mg of benzo(a)pyrene(BP). Various types and ages of ginseng extracts at 2.5mg/ml were orally administered. All the mice were sacrificed at the 9th week. The following results were obtained. In the dried fresh ginseng extract treated group, the incidence of lung adenoma induced by BP was 63.9% and its incidence was reduced to 48.3%, 52.5%, 51.8%, 47.5% and 44.1% after co-treatment with 1.5, 3, 4, 5 and 6 year-dried fresh ginseng, respectively. The incidence of lung adenoma induced by BP on the white ginseng extract treated group was 41.3% and decreased to 31.0%, 46.0%, 44.0% and 26.5% after co-treatment with 3, 4, 5 and 6 year-white ginseng, respectively. In the red ginseng extract treated group, the incidence of lung adenoma induced by BP was 47.5% and its incidence diminished to 40.7%, 35.0%, 30.1%, 30.0% and 26.3% after co-treatment with 1.5, 3, 4, 5 and 6 year-red ginseng, respectively. From the above results, we concluded that a statistically significant anticarcinogenic effect was observed in extracts of 6 year-dried fresh ginseng, 6 year-white ginseng, and 4, 5 and 6 year-red ginseng and it is suggested that the anticarcinogenicity of ginseng varies according to the types and ages Key words Ginseng extract, types and ages. anticarcinogenic, newborn mice, lung tumor.

The authors have already shown that 6 year old red ginseng extract or its powder has remarkable anticarcinogenic effects. In this study, we further investigated whether fresh ginseng or white ginseng has similar anticarcinogenic effects and also if their anticarcinogenic effects are related to the types and ages of ginseng using Yun's anticarcinogenicity test (9 week medium term bioassay model). Dried fresh ginseng and red ginseng at 1.5, 3, 4, 5 and 6 years, and while ginseng at 3, 4, 5 and 6 years were used. The following results were obtained: 1) In the dried fresh ginseng treated groups, the incidence of lung adenoma induced by benzo(a)pyrene was 41.39) and its incidence was reduced to 31.2%, 30.0%, 31.3%, 30.7% and 27.8% after co-treatment with 1.5, 3, 4, 5 and 6 year-dried fresh ginseng, respectively. A significant effect was observed only in 6 Year-dried fresh ginseng. 2) In the white ginseng treated groups, the incidence of lung adenoma induced by benzo(a)pyrene was 45.0% and its incidence decreased to 41.3%, 38.0%, 31.6%, and 25.3% after co-treatment with 3, 4, 5 and 6 year-white ginseng, respectively. Five and 6 year-ginsengs showed significant inhibition of lung adenoma. 3) In the red ginseng treated groups, the incidence of lung adenoma induced by benzo(a) pyrene was 48.6% and its incidence diminished to 37.9%, 41.7%, 31.7%, 28.3% and 25.5% after co-treat-melt with 1.5, 3, 4, 5 and 6 year-red ginseng, respectively. In 4, 5 and 6 year-ginsengs, the anticarcinogenic effect was prominent. From the above results, we concluded that a significant anticarcinogenic effect was observed in 6 year-dried fresh ginseng, 5 and 6 year-white ginsengs, and 4, 5 and 6 year-red ginsengs.

It order to extract the soluble organic substances of Korean ginseng effectively, the ginseng extract have been made by using amylase. The investigation on the optimum condition of enzyme reaction was carried out, and the amounts of gained extract and its saponin pattern were compared among the ethanol extract, water extract and enzyme extract. The results obtained are summerized as follows. 1. The gaining ratio or ginseng extract was the highest value when the raw ginseng and dried ginseng were extracted in the concentration of 7.5% and 5% with 0.3%∼0.6% enzyme for 25 hour. 2. The amounts of ethanol extract, water extract and enzyme extract were 9.14%, 17.23% and 23.73% in case of raw ginseng and 64.09%, 72.52% and 74.36% in case of dried ginseng, respectively. The amount of enzyme extract was increased as much as 6∼14% in case of raw ginseng, and 2∼10% in case of dried ginseng compared with that of ethanol and water extract. 3. The absolute content of saponin was nearly constant in spite of the different extraction method and all of the ginseng saponin pattern of thin-layer chromatograms were almost same.

Chemical compositions were investigated by harvested months and produced methods. The level of crude protein and crude ash of ginseng leaf tea harvested in July was slightly higher than it harvested in September. However, the level of crude fat and carbohydrate of ginseng leaf tea harvested in September were higher than it harvested in July. The results indicated that the harvest month influenced the chemical composition of the ginseng leaf tea. Also, the level of free sugar was increased when the ginseng leaf team harvested in September was produced by FHT(fermented and then hot-air dried) or HHT(heated and then hot-air dried). The results indicated that the subjects were preferred the color of ginseng leaf tea which was harvested in July. However, they were preferred the aroma and ginseng's aroma which was harvested and produced by HHT in September. Because they responded that the ginseng leaf tea tasted too bitter, it suggested that the taste of bitterness needed to remove. Also, the astringent, the savory, after aroma, and after say cry of the ginseng leaf tea was improved with FHT or HHT, and those results obtained from September's harvest rather than July's. Therefore, the overall quality of ginseng leaf tea which was harvested in September and produced with FHT or HHT were evaluated better than it of DHT(dried on the shade and then hot-air dried).

The Chinese ginseng roots were collected at twelve places of Jilin Province and two places of Liaoning Province in China and their appearances were compared with those of the Korean ginseng roots. The color of the most of the Chinese red ginseng was brown or dark brown and the color of many of the Chinese dried ginseng was pale yellow and the root-age of the most of the Chinese red ginseng as well as the Chinese dried ginseng was evaluated five or six year regardless of the collection places, so it cannot be easily concluded that the color and the root-age of the Chinese ginseng roots are different from those of the Korean ginseng roots. However the rhizomes and the lateral roots of the Chinese ginseng roots were poorly developed and many of them did not have either rhizome or lateral roots. Moreover the rhizomes of the Chinese red ginseng as well as the Chinese dried ginseng were much more easily removed than those of the Korean red ginseng and the Korean white ginseng. Therefore it is thought that the development status of the rhizome and the lateral roots of the Chinese ginseng roots are quite different from those of the Korean ginseng roots.

Background: Dried and red ginseng are well-known types of processed ginseng and are widely used as healthy food. The dried and red ginseng quality may vary with the storage period of raw ginseng. Therefore, herein, the effect of the storage period of fresh ginseng on processed ginseng quality was evaluated through multicomponent quantification with statistical analysis. Methods: A method based on ultrahigh performance liquid chromatography coupled to triple quadrupole mass spectrometry in multiple-reaction monitoring mode (UPLC-MRM-MS) was developed for quantitation of ginsenosides and oligosaccharides in dried and red ginseng. Principal component analysis and partial least squares discriminant analysis were conducted to evaluate the dynamic distributions of ginsenosides and oligosaccharides after different storage periods. Results: Eighteen PPD, PPT and OLE ginsenosides and nine reducing and nonreducing oligosaccharides were identified and quantified. With storage period extension, the ginsenoside content in the processed ginseng increased slightly in the first 2 weeks and decreased gradually in the following 9 weeks. The content of reducing oligosaccharides decreased continuously as storage time extending, while that of the nonreducing oligosaccharides increased. Chemical conversions occurred during storage, based on which potential chemical markers for the storage period evaluation of fresh ginseng were screened. Conclusion: According to ginsenoside and oligosaccharide distributions, it was found that the optimal storage period was 2 weeks and that the storage period of fresh ginseng should not exceed 4 weeks at 0 ℃. This study provides deep insights into the quality control of processed ginseng and comprehensive factors for storage of raw ginseng.
