Red ginseng extracts were prepared with various concentrations of ethanol. Extract yields were examined and saponins in the extracts were identified and determined by TLC and HPLC, respectively. Yields of the extracts, $19.7{\sim]50.3%$, were the highest in water extract and showed significant decrease with the increase of ethanol concentration used for extraction. Contrary to the extract yields, saponin yields from red ginseng were conspicuously increased with the increase of ethanol concentration and were $3.47{\sim}5.13%$ of crude saponins and $1.28{\sim}1.93%$ of six major ginsenosides. Saponin contents in the red ginseng extracts were $6.9{\sim}24.2%$, of crude saponin and $2.57{\sim}9.22%$, of six major ginsenosides.

The effect of puffing treatments on the sensory qualities improving of Ginseng Extract were investigated in the good products for rejecting soil flavor as Ginseng foreign bad taste, through chemical analysis and actual manufacturing practice, the following results were obtained. Puffing treated<15kg / ㎠psi> ginseng has produced a marked increase in soluble solid, crude saponin yield to the extent of 10% and without soil taste as compared with control Ginseng. Optimum Ginseng ethanol extraction condition were 90$\^{C}$ for 8 hours, which was cheap operating cost and color, apperance, total solid yield of Ginseng extracted products. For 70% ethanol extraction in temperature range of 60∼90$\^{C}$ for 8 hours, the higher temperature resulted higher yields in solids and Ginsenoside Especially, GinsenosideRgl as most effective physiological function component yield was increased in 18% by puffed Ginseng than control Cinseng products. The Hunter's color, L. a and b values of Ginseng extract were 31.09, 21.9 and 49.5 and increase brown and red color value and total Δ Evalue.

For bioassay of the various extracts of ginseng, the growth determination method using Saccharomyces cerevisiae which was cultured with various doses of the extracts, was studied The water extract, Powder. and ethanol extract were more effective (about 45∼ 110% increase) than saponins or its fractions (about 20∼35% increase). The cold methanol residue showed a increase effect but it was not significant. The bioassay curves for the water extract, ethanol extract, the butanol extracted saponins and the cold methanol- residue were made from the experimental data. From these curves it is possible to find the relation between dose and effectiveness and the optimal doses of various ginseng extracts, and the amount of extract in a sample can be estimated The .angers of sample amount were 0.01% (100ppm) ∼0.32% (3200ppm) fo. the water extract, 0.025% (150ppm)∼0.1% (1000ppm) for the ethanol extract, and 0.008% (80ppm)∼0.016% (160ppm) for the saponins. It was impossible to determine the range for the cold methanol- residue, The acceleration effects on the cell proliferation by a only 0.0008% (8ppm) of the diol- and triol-saponin were measurable in earlier Period (24 hour treatment).

$H_2$-FID 박층 자동 검출장치를 사용하여 인삼차 및 인삼엑기스 중의 사포닌을 분별 정량 하였다. 아울러 인삼차와 인삼엑기스의 품질관리에 응용하기 위하여 분석 최적조건과 정량시의 회수율에 관하여 조사하였으며 그 결과는 다음과 같았다. 1. 본 정량법은 품질관리에 있어서 제품생산에 사용하려고 하는 인삼엑기스와 싣제로 제품에 사용된 인삼엑기스와의 동일품질여부를 판별하는 데에 좋은 방법이 될 수 있었다. 2. 제품중의 총 사포닌 농도의 증가에 따라 거의 모든 각개 사포닌 peak면적도 정량 적으로 증가되었다. 그러나 고농도로 인삼엑기스를 함유하는 인삼차를 시료로 사용 했을 경우에는 몇몇 Peak면적이 정량적으로 증가되지 않는 경우가 있었다. 3. 본 분석방법에 있어서 보다 정착한 분석을 위하여는 고농도시료를 소량 취하는 것보다 저농도시료를 다량 취하는 경우가 더 좋았다. 3. 분별정량에 있어서 제품중의 인삼엑기스 함량은 0.59~1.59정도로 취하여 분석할 경우가 가장 좋았다. 4. 사용된 총 사포닌에 대한 각개 사포닌의 회수율은 99.5%였다.

홍삼 추출물을 첨가한 두부를 제조함에 있어 홍삼 추출물 첨가량이 두부의 품질과 저장성 그리고 항산화 활성에 미치는 영향을 조사하였다. 건조 대두를 기준으로 홍삼 추출물을 $0.5{\sim}2%$ 첨가하여 제조한 두부와 첨가하지 않은 두부의 물성, 색도, 관능의 차이를 비교하였다. 두부의 texture는 견고성과 탄력성에서만 홍삼 추출물의 첨가량에 따라 다소 증가하는 경향으로 홍삼 추출물을 2% 첨가한 두부에서 유의적 차이가 나타났고, 두부의 색도는 L, a, b값 모두 유의적으로 증가하였다. 관능검사 결과 color에 대한 기호도가 떨어지는 경향을 보여 주었으나 홍삼 특유의 맛이 유의적으로 감지되면서 전체적인 기호도는 통계상 유의적 차이가 보이지 않아 홍삼 추출물의 첨가가 소비자의 기호에 특별한 거부감을 일으키지 않는 것으로 나타났다. 두부를 $15^{\circ}C$에서 보관하면서 pH, 탁도 그리고 총 균수의 변화를 측정한 결과 저장 초기에는 변화가 없다가 pH와 총 균수는 저장 4일부터, 탁도는 저장 6일부터 변화하는 것으로 나타나, 이는 홍삼 추출물이 첨가된 두부가 홍삼 추출물이 첨가되지 않은 두부보다 미생물 생육이 억제되어 두부의 저장성이 향상되었음을 의미한다. ORAC assay를 이용한 두부의 항산화 활성은 첨가된 홍삼 추출물의 농도에 비례하여 antioxidant 활성이 유의적으로 증가하는 경향을 나타내었으며, ORACOH. assay에서 는 홍삼 추출물을 첨가한 두부 추출물이 홍삼 추출물의 농도에 비례하여 pro-oxidant 활성을 보여 주었다.

Red ginseng extract was added to Yanggaeng to determine a practical use for the herb which has medical usage and functionality. We examined the antioxidant activity and quality characteristics of Yanggaeng prepared with different amounts (as ratios of 1%, 2%, 3% to the total materials) of red ginseng extract, as well as those of commercial red ginseng Yanggaeng. The antioxidant activity of the Yanggaengs samples was estimated by the DPPH free radical scavenging activity, $ABTS^{+\cdot}$ scavenging activity, and reducing power. The antioxidant activity of the Yanggaeng increased as a result of the addition of the red ginseng extract. Levels of polyphenol compounds and flavonoids increased according to the extract concentration. The quality characteristics of the red ginseng Yanggaeng were estimated in terms of pH, sugar content, viscosity, color, texture profile analysis, and sensory evaluations. With increasing concentrations of the extract, viscosity and sugar content increased, but pH decreased. In terms of the overall palatability, color, taste, flavor, and hardness, the 3% red ginseng Yanggaeng was determined as the best among the tested samples. Also, the 3% red ginseng Yanggaeng had higher scores than the commercial red ginseng Yanggaeng.

It has been known that ginseng extract contains several polyacetylene components. But we found only two polyacetylene components in the freshly prepared ginseng extract. Long-term preservation of ginseng or ginseng extract produced many artifact polyacetylenes. The ratio of artifact/genuine polyacetylene was determined by TLC-densitometry on long-term preserved ginseng samples. The results indicated that the ratio was increased proportionally with the span of preservation.

Dry rehydratable film (Petrifilm) method was compared with the standard pate count (SPC) method for estimation of total bacteria in ginseng products. Ginseng products (7 sample) was analyzed for total count by the SPC, and Petrifilm methods, respectively. In the case of ginseng tea, ginseng extract, ginseng extract pill, ginseng powder capsule, and ginseng extract tea, they showed non-significant values at the 1% level. However, the values of ginseng powder and tablet showed significant at the 1% level. These results generally indicate the suitability of the dry rehydratable film methods as alternatives to the SPC method for estimating of total bacteria in ginseng product samples except to ginseng powder and ginseng tablet.

In order to establish effective production o( ginseng extracts from tail ginseng, the tail ginseng was soaked in the different concentration and the amount of ethanol, and iii course of the time and duration of the extraction. The yield of ginseng extract, proximate chemical components and its saponin pattern were investigated. The results obtained are as follows: 1. The amount of tail ginseng extracts decreased in accordance with the increment of ethanol concentration. The yield of the extracts were 50.86%, 44.42%, 37.82%, 35.52% and 33.42% extracted by water.30%. 50%, 70%, and 90% ethanol, respectively. 2. The reasonable proportion of tail ginseng and solvent (35% ethanol) u·as 1 : 4 (42.68%)∼1 : 6 (45.92%) 3. The yield of tail ginseng extract increased according to the extraction time, but it was the most suitable that the tail ginseng extracted for 5 hour (43.32%)∼10 hour (45.60%). 4. The chemical composition and viscosity of tail ginseng extract was decreased but it's transmittance was increased, and the saponin pattern of T.L.C. showed same tendency in the course of extraction time.
