  • Ocimum gratissimum is a common plant in the tropics and has been used in food and medicine. Its usage in food and medicine could be attributed to its phtyochemical and antimicrobial properties. In this study we investigated the proximate, phytochemical, and antimicrobial attributes of air dried leaves of O. gratissimum. The aqueous extract was found to contain phtyochemicals with alkaloid and saponin present in appreciable amounts. The proximate analysis (crude protein and crude fibre content were 15.075% and 17.365%, respectively) showed that the leaf could be a good source of protein and fibre. The aqueous ethanolic extract of the leaf exhibited activity against a wider range of organisms when compared to the aqueous extract at the investigated concentrations. Aqueous ethanolic extracts of O. gratissimum leaf was active against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, and Bacillus cereus and the aqueous extract of the leaf was active against P. aeruginosa.

  • We quantitatively analyzed eight varieties of 6-year-old red ginseng, including four local landraces from the Inje, Geumsan, Jinan, and Punggi regions and four new varieties, Chunpoong, Yunpoong, Guempoong, and K-1, for 10 ginsenosides, acidic polysaccharide, crude polyacetylene, and total polyphenol content to find out which varieties are most suitable for producing red ginseng. Most of the new varieties contained more ginsenosides than the local landraces. While the acidic polysaccharide content of Geumsan red ginseng was lower than that of the others, its crude polyacetylene content was the highest, with a mean of 33.99%. The Inje, Geumsan, and Jinan red ginseng had a significantly higher total polyphenol content than the others.

  • In order to investigate the optimal drying condition of white ginseng by using bulk air drier(130 x 62 x 65cm), drying curves, diffusion coefficient at various drying temperature, the energy of activation, variation of color intensity and chemical components during drying of white ginseng were studied. Fick's second low of diffusion for diffusion out of spheres was successfully applied to describe the drying of white ginseng. It was found that the diffusion coefficient of water was 2.2x107, 9.0x107 cm2/sec at drying temperature 4$0^{\circ}C$, 55$^{\circ}C$, respectively. An Arrhenius type temperature dependency of moisture diffusivity was found, the energy of activation being 18.8 Kcal/g mol. Color intensity of white ginseng dried at various drying temperature was increased with an increase in drying temperature. The contents of crude protein, reducing sugar and crude saponin during drying of white ginseng were gradually decreased as increasing of drying time. And with the sensory evaluation by multiple comparison difference analysis, the optimal drying temperature of white ginseng was between 45$^{\circ}C$ and 5$0^{\circ}C$.

  • This study was designed to compare the inhibitory effects of algae components such as alginic acid and chlorella extract with the red ginseng saponin and garlic components such as alliin and scordinin on obesity. These components supplemented to basic diet were fed ad libitum to Sprague Dawley rats for 4 weeks, and the inhibitory effects on obesity were evaluated by measuring body weight gain and feed efficiency, the contents of glucose and cholesterol in serum, lipase activity in serum, lipid contents in liver and adipose tissue around epididymis and ovarium, and Lee index, etc. Among the inhibitory effects of these components on obesity, Na-alginate($71\%$) was the most effective (p<0.01), and the others were effective (p<0.001) in the order of scordinin ($76\%$) = chlorella ($76\%$)> alliin ($86\%$) for body weight gain, but Na-alginate ($68\%$) was the most effective, followed by alliin ($79\%$) for feed efficiency (p<0.001). In the inhibitory effects on lipid accumultion in liver and adipose tissue, Na-alginate ($84\%$) among these components was the most effective (p<0.001) in liver, but Na-alginate ($54\%$) was the most effective (p<0.001), followed by alliin ($64\%$), and followed by scordinin ($66\%$) in adipose tissues around epididymis and ovarium (p<0.001). The inhibitory effect on obesity evaluated by Lee index was observed in Na-alginate ($91\%$) only (0.001). The decreasing effects of lipid content in liver by these components were effective in the order of alliin ($40\%$)> saponin ($58\%$)> Na-alginate($62\%$)> chlorella ($64\%$)> scordinin ($74\%$) (p<0.001). G lucose contents in serum were significantly decreased in cases of Na-alginate ($67\%$), saponin ($73\%$), scordinin ($74\%$) and alliin ($83\%$), and cholesterol contents in serum were significantly decreased in cases of Na-alginate ($82\%$), chlorella ($86\%$) and saponin ($89\%$) (p<0.001). The increasing effect of lipase activity in serum was effective in cases of Na-alginate ($109\%$) and saponin ($104\%$), while garlic components such as alliin and scordinin, and chlorella were decreased. It is proved that the inhibitory effect of alginic acid which is the major component of brown algae on obesity was more effective than those of ginseng and garlic components such as saponin, alliin and scordinin.

  • This study was devised to observe the cytotoxlc activities of petroleum-ether extract of Panax ginseng root(crude Gx) and its partially purified fraction from silicon acid column chromatography(7:3 CX) against sarcoma-180(5-180) and Walker carcinosarcoma 256(Walker 256) in vivo, and murine leukemic lymphocytes(L1210) and human rectal cancer cell(HRT-18) and human colon cancer cells(HT-29 and HCT-48) in vitro . Each cell-line was cultured in medium containing serial concentrations of the crude Gx or 7:3 Gx in vitro. A highly lipid soluble compound in the extract of Panax ginseng root was cytocidal to murine leukemic cells and human colon and rectal cancer cells in vitro In the meantime, ginseng saponin derivatives did not cytotoxic effects at its corresponding concentration. The growth rates of the cancer cells in medium containing ginseng extracts were inhibited gradually to a significant degree roughly in proportion to the increase of the extract concentration. The cytotoxic activity of 7:3 Gx was about 3 times more potent than that of crude Gx, one unit of cytotoxic activity against L121f cells being equivalent to 2.54$\mu\textrm{g}$ and 0.88 $\mu\textrm{g}$ for the crude Gx and 7:3 Gx, respectively. The Rf value of the active compound on silica -gel thin layer chromatography with petroleum-ether/ethyl ether/acetic acid mixture (90:10:1, v/v/v) as a developing solvent was 0.23. The survival times of mice inoculated with S-180 cells were extended about 1.5 to 2 times by the 7:3 Gx treatment compared with their control group. The significantly decreased hemoglobin values of rats after inoculation with Walker 256 were recovered to normal range by oral administration of the crude Gx. The synthetic levels of protein, DNA and RNA in human colon and rectal cancer cells were significantly diminished by treatment with the crude Gx, which can explain a part of the origin of its anticancer activity.

  • In order to investigate the inferior factor of red ginseng quality, the contents of various chemical components, physico-chemical properties and arrangement state of ginseng cells were observed. Contents of total reducing sugar, reducing sugar, crude protein, crude fibre and specific gravity of inside white part of red ginseng were less than those of normal part. But differences in content of crude saponin, HPLC pattern of ginsenosides and reducing ability for DP P H(1,1-dipheny 1-2-picrylhydrazyl) between normal and inside white part of red ginseng were not found. The optical density of 1 water extract of normal part of red ginseng did not differ from that of inside white 1 part of red ginseng, but the visible and UV absorbance of acid hydrolyzate of normal red ginseng showed higher than those of inside white part of red ginseng. The differences in the internal color and tissue of normal and inside white part of red ginseng were easily found with naked eye, and by the microscopic fractography, the orangement state of ginseng cell in the inside white part of red ginseng was less dense than that in normal red ginseng.

  • The ginseng residue, a by-product of ginseng tea manufacture, was used as growth promoting substance in the submerged cultivation of Basidiomycetes for its effective utilization. Ginseng residue contained about 46% of total sugar, 14% of crude protein, 12% of ash, and 0.16% of crude saponin. Among inorganic substances in ginseng residue, amount of Mg, Na, K and Ca were much more than other inorganic substances. All ginsenosides existed in red ginseng residue. Ganoderma lucidum and Pleurotus ostreatus could be excellently cultured in potato dextrose broth. Most effective additional concentration of residue extract for growth of these fungi was shown to be 0.2%, and the contents of crude protein and amino acid in mycelium were increased when 0.5% of residue extract were added to the medium.
