This study was conducted to investigate chemical and physical characteristics of pectin in Korean ginseng plant. The results obtained are as follows: 1, The molecular weight of the pectin in ginseng plant was in the range of 1.1-2.4x 104 and athydrouronic acid content in the pectin was 97.98%. 2. The intrinsic viscosity of pectin as well as apparent visosity of the pectin in the roots were increased with cultural period. 3. The IR spectra of ginseng pectin showed the OH stretch, C-H bending vibration and the vibration of ester group carboxyl. 4. Sugars present in galacturonic acid, glucose, arbinose, xylose, galactose and rhamnose.

Healthy ginseng pudding was made with different doses of two gelling agents and stored at $37^{\circ}C$ for eight weeks. And then quality characteristics and palatability were measured. Sweetness and pH level increased in newly made ginseng puddings but decreased during storage. Acid taste decreased but increased during storage in A (pectin 0.2%+agar 0.6%). But it increased but subsequently decreased in B (agar 0.8%). Acidity in C (agar 1%) remained unchanged until six weeks but slightly increased at 8 weeks of storage. Texture increased in all specimens but subsequently decreased. Chromaticity value of L decreased in all specimens before increasing while the values of a and b increased and subsequently decreased. In texture examination, hardness and adhesion were higher in C (agar 1%) and lower in A (pectin 0.2%+agar 0.6%). There were no differences in elasticity among three specimens. Cohesion was higher in C (agar 1%) while it showed a similar level in A (pectin 0.2%+agar 0.6%) and B(agar 0.8%). Stickiness and chewiness were higher in C(agar 1%) but lower in A(Pectin 0.2%+agar 0.6%), compared with C(agar 1%) specimen. In sensory test, overall palatability was higher in A (Pectin 0.2%+agar 0.6%). In conclusion, ginseng pudding with 0.6% agar and 0.2% pectin exhibited better quality. And ginseng pudding has potential to be developed as healthy dessert considering ample physiological and functional properties.

This study was conducted to investigate the characteristics of nonstarchy polysaccharides in Korean ginseng, (Panax ginseng C.A. Meyer). The results obtained are as follows. 1. The total sugar content of ginseng roots were decreased with increasing the cultural period. On the other hand, the crude fiber content was increased with that of the ginseng leaves or stems. But the crude fiber in root was much less than that of leaves and stems. 2. The dietary fiber content of ginseng root on 5 years old was 14.20% as neutral detergent fiber, 9.08% as acid detergent fiber, hemicellulose 5.12%, cellulose 7.98% and lignin of 1.10%, respectively. 3. Much more pectin was found in ginseng roots which was cultivated for shooter Period. And it was contained much more in the root than in the leaves and stems. 4. ginseng hemicellulose content in root was 5% to 10%. It was decreased with increasing: cultivated period. Hemicellulose was constituted of xylose, arabinose, glucose, rhamnose and xylose of these sugars was the predominant. 5. X-ray diffraction Pattern of ginseng cellulose showed maximum intensity at tile interplanar angle of 4.1$^{\circ}$.

The structural components of cell wall in various parts of Korean ginseng were analysed. Pectin was abundant in the cortex and epidermis of root, and leaf. Hemicellulose in root was more than in other parts of ginseng. Cellulose content of stem and seed coat was much higher compared to other parts and lignin content was highest in seed coat.

한국산 수삼을 주서로 갈아 30분간 끓인 다음 착즙, 원심분리하여 당을 추출하여 HPLC 및 TLC로 당을 분석하였다. 분석 결과, 수크로오스는 3.77%, 말토오스는 3.5%, 포룩토오스는 0.09%로 나타났다. 다른 소당류는 검출되지 않았다. NMR 분석 결과 전분은 $\alpha$-1, 4-글루코시드 결합만을 나타내고, 요오드 반응은 아밀로오스(DP 117) 흡광도의 92%를 나타냈기 때문에 아밀로오스만으로 이루어진 것으로 나타났다. 카르바졸법으로 펙틴을 분석한 결과 갈락투론산으로 0.22%를 나타냈다.

The method for colorimetric determination of acidic polysaccharide from Panax ginseng was investigated. It is possible to apply the method of carbazole-sulfuric acid to determination of pectin, and also to measure the amount of pectin in the mixture of various high molemlu compounds such as starch. cellulose and gum, etc. When the method of carbazole-sulfuric acid was applied to determine the amount of acidic polysaccharide, optical density at 525 nm increased linearly with an increase in the concentration of pure acidic polysaccharide. Effective extraction temperature with water for the determination of the amount of ginseng acidic polysaccharide (GAP) was $80{\circ}C$. In order to separate or concentrate GAP it was appropriate to precipitate the extract only once with 80% ethyl alcohol. GAP was very stable at $100{\circ}C$ for 4 hrs in aqueous solution and between pH values of 5.0~ 12.0.

Red ginseng was extracted with water and analyzed for yield, saponin, pectin and other chemical composition. It was found that: (1) The total solid content in extract after 6 times of extraction was 46.8%,: including 13.6% of centrifugal residue; (2) 83.7% of total extractable solids and 86% total saponin was extracted after the initial three runs of extraction. (3) No significant changes were observed in HPLC pattern of extracted saponins over a range of extractions; (4) The ratio of centrifugal residue to total solids increased as the number of extractions increased; (5) The ratios of fat, protein, reducing sugar and pectin contents decreased with repeating extraction while those of crude fiber, total sugar and 35% alcohol insoluble residue increased when they were compared with total solids.

To develop new therapy for prevention and treatment of hair loss is very important according to increase of the number of hair loss people. The aim of this study was to investigate the hair growth promoting effects of pectin lyase-modified red ginseng extract (GS-E3D). We examined antioxidant and anti-inflammatory effects, human hair dermal papilla cells (HHDPC) proliferation, and testoterone-induced $5{\alpha}$-reductase inhibitory effects. GS-E3D show not only 1,1-diphenyl-2-picryhydrazyl (DPPH) radical scavenging activity and xanthine oxidase inhibitory effects as an anti-oxidant property, but also lip-oxygenase and hyaluronidase inhibitory effects as an anti-inflammatory property. Human hair dermal papilla cells proliferation by GS-E3D was higher than those of minoxidil or finasteride, using the positive controls. Moreover, GS-E3D exhibited $5{\alpha}$-reductase inhibitory activities after stimulating by testoterone. The present results indicate that GS-E3D has a potential to be as an hair growth promoting agent for cosmetic materials.

Pectin lyase-modified red ginseng extract (GS-E3D) is a newly developed ginsenoside Rd-enriched ginseng extract. This study was designed to investigate the skin safety of GS-E3D. Single oral toxicity, single dermal toxicity, bovine corneal opacity and permeability (BCOP) assay, skin irritation test with $SkinEthic^{TM}$ human epidermis model, skin sensitization local lymph node assay, and human patch test, were examined. The oral and dermal $LD_{50}$ value of GS-E3D was over 2,000 mg/kg in rats. GS-E3D was identified as a non-irritant to skin in BCOP assay, human epidermis models, and patch test from the 32 human subjects. The skin sensitization potential of GS-E3D was less than 25% in local lymph node assay. These results indicate that GS-E3D can be used as a safe ingredient without adverse effects in various skin care products.

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.
