Aloe gel layer is well known as raw materials of medicines and cosmetics due to their antioxidant and anti-inflammatory properties. In aloe gel extracting process, the outer part of the leaf was removed. It contains high quality of fiber and many nutrients. However, this part is thrown away and generally used as fertilizer. The purpose of this research was to examine the important nutrient of Aloe saponaria. Moreover, the feasibility of using aloe as a dietary supplement by feeding fermentation treatment of aloe was investigated. To do this, the aloe leaf was divided into several parts including leaf skin, bottom of the leaf, tip of the leaf, middle of the leaf, and leaf flesh. Then the saponin content were analyzed from each part. The extraction method was used to clarify the saponin content. The aloe then fermented to improve it benefit. The fermented Aloe then given as dietary food to group of pig. Finally, the appropriate feed level was determined and the pork meat quality was analyzed. The extraction of saponin shows that the highest concentration of saponin located on the skin of the leaf. The feeding experiment shows that there is no significant difference in pig growth without aloe dietary food and groups with aloe as dietary food. It was conclude that fermented aloe can replace the pigs normal feeder as an alternative feeding solution.

We investigated the changes in saponins during the cultivation of soybean sprout. Crude saponin content was 4.15mg/g in germinated soybean and reached its peark (5.33mg/g) in soybean sprout cultivated for six days. Saponin content in the cotyledon, stem, and root of the soybean sprout cultivated for six days were 4.17, 7.46, and 7.45mg/g, respectively. Soyasaponins extracted from the soybean sprout were analyzed with LC-electrospray ionization (ESI)-mass spectrometry, in which a reverse phase $C_18$ column was used for separation of saponins. In the soybeen sprout, group B saponin, I, II, III, IV, and V increased 7, 2, 1.4, 8.7, and 3.3 fold, respectively, compared to those in the soybean seed. Group B saponin I, II, III, IV, and V in the stem of the soybean sprout were 10.53, 1.45, 10.49, 5.72 and 8.14 fold the level of those in the cotyldon, respectively. In the root, the contents of group B saponin I, III, IV, and V were 5.54, 2.77, 4.86 and 9.73 fold, respectively, higher than those in cotyledon, but the content of group B saponin 2 was 2.96 fold less than that in cotyledon. These results indicate that the biosyntheses of group B saponins are differentially regulated in growing soybean sprout.

During the controlled atmosphere storage (CA), fresh ginseng showed good appearance in quality, and other deterioration of freshness was not observed until 12 weeks. On the other hand, MA storage had kept freshness only in treatment of 1 until 8 weeks. There was no significant difference between treated and non-treated sample with preservatives, and not treated sample was not infected with various different fungi. Moisture contents and hardness of ginseng in all treatments were not changed much until 12 weeks, and surface shrinkage did not occur either. But shear stress increased somewhat in all treatments after 12 weeks. The granule of microstructure in tissue diminished slightly. The apparent Quality of red ginseng was good until 4 weeks of treatment. But as time passed, white skin and wrinkled skin were generated and darkened in its color. B-1 in CA and E-1 in MA were found to be the most favorable one. The content of crude saponin did not change significantly during storage of CA or MA by preservation conditions and period. Though a small increase in saponin content from 4.92% to 5.43% was recognized in B-1, which was treated with preservative and 6.0% In B-2, control, this could rather explain increment of soluble component by butanol. Thus, there was no change in total contents of ginsenoside pattern and composition of each content. The Rbl content in B-1 and B-2 were 0.98%, and 0.97%, respectively, whereas that of control was 0.96%. E-1 of MA, treated with preservative was 5.32% after 12 weeks, but was 5.73% in control, indicating that ginsenosides pattern was quite similar to that of CA storage.

The purpose of this study was to extract saponin efficiently from ginseng leaves and peelings by macerating them with microbial enzyme. To begin with, we selected G-211 strain having the highest macerating activity among several rotting molds of fresh ginseng. Crude macerating enzyme was prepared from this G-2l1 strain by ammonium sulfate precipitation, and was applied to macerating leaves and peelings of ginseng. The optimal pH of the enzyme for maceration was 5.0 in both leaves and peelings of ginsen g. The optimal pH for the extraction of soluble matters and saponins was 4.5 and 5.5 in ginseng leaves and ginseng peelings, respectively. When this enzyme was treated together with crude cellulase from Trichoderma viride (To4), the extract content of saponin was 3.45% for ginseng leaves and 3.90% for ginseng peelings. Their yields were 39.8 % and 39.3 % of total saponin amounts in ginseng leaves and ginseng peelings, respectively. The ginsenoside patterns of saponins extracted with the treatment of enzymes were also studied by HPLC technics.

The purpose of this study was to examine the changes in seasonal bioactive components of 4 and 6 years old fresh ginseng (Panax ginseng) and to provide basic information on the development of functional food using fresh ginseng. Seasonal changes were investigated by ginseng saponin analysis using HPLC method and acidic polysaccharides by carbazole sulfuric acid method. Total saponins showed the highest content of fresh ginseng collected in May, followed by March, July, and September. Fresh ginseng collected in May showed 2.5 times (4 years old) - 3.0 times (6 years old) higher than fresh ginseng collected in September. Acidic polysaccharides showed high content of fresh ginseng collected in March and September, and low content of fresh ginseng collected in May and July. From these results, the fresh ginseng collected in May can develop high concentrations of saponin. On the other hand, fresh ginseng collected in March and September is thought to be able to develop high concentration products of acidic polysaccharides.

For the elucidation of significance of saponin as quality criterion of ginseng ginsenoside content(GC) and ginsenoside pattern similarity(GPS) by simple correlation were investigated in relation to red ginseng quality factors, age, plant part, harvest season, mineral nutrition, soil physical characteristics, growth light and temperature, shading material, growth location, physiological disease and crop stand through survey of ginseng plantstions, field experiments, water culture and phytotron experiments. Effect of tissue culture was also reviewed. GC was negatively correlated with good quality of red ·ginseng and positively with bad quality. Age did not show any consistency with GC but GPS was less with the increase of age difference. GPS was less or not significant between taproot that is lowest in GC and epidermis highest, and significant between leaf and taproot. Harvest season marked with the lowest GC and Pattern was also different. Nutrient imbalance, the increase of hazardous soil nutrient and physical condition to growth increased GC, but GPS was little different. The higher the growth lights intensity and temperature the higher the GC but GPS was little changed. Root rust increased GC, but root scab decreased it. Sponge-like and inside cavity phenomena increased GC. Ginsenoside pattern of cultured tissues and rootlet showed great variation. These results strongly indicate that there are optimum saponin content and ginsenoside pattern and that these are accomplished under the optimum growth condition.

Optimal conditions for hot water extraction of Liriope spicata tuber were investigated with changes in solvent ratio(2∼6 fold) and heating time(1∼5 hr) by response surface methodology. The content of extractable solids increased with an increased in solvent ratio, and the highest content showed at heating time of 3 hr. The content of total steroid saponin increased with a decrease in solvent ratio, and increased with an increase in heating time at increasing the solvent ratio. The content of non-reducing sugar containing oligosaccharides at a lower solvent ratio didn’t show changes depending on heating time, while that at a higher ration decreased with an increase in heating time. Optimal extraction conditions using hot water as the limited conditions of 15∼18% extractable solids, 1.5∼2.0% total steroid saponin, 6∼8% reducing sugar, 6∼7% non-reducing sugar and 13∼15 brix were 3 hrs of heating time and 4 fold of solvent ratio.
