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.

Anatomical and physico-chemical properties of some nutrient and tonic crude drugs have been estimated and compared. Resin duct and druse crystal were observed more in Acanthopanax Cortex than in Ginseng Radix. Bast fiber bundle and solitary crystals were abandantly present in Glycyrrhizae Radix. Mucilage crude drugs contained mucilage ducts and bundles of raphides as common components and their arrangements of vascular bundles were different. TLC analysis showed different patterns of saponin, flavonoid, ${\gamma}-aminobutyric$ acid and sitosterols.

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$0^{\circ}C$.

비만치료식 개발을 위한 기초연구의 일환으로 전보에서 식물섬유중에서 가장 효과적으로 비만을 억제하는 것으로 알려진 알긴산과 담수녹조인 chlorella, 그리고 중요 생약인 인삼과 마늘의 유효약리성분인 saponin과 alliin, scordinin의 첨가에 의한 비만억제작용을 비교${\cdot}$검토한 결과를 보고한다. 이들 성분들의 첨가에 의한 비만억제효과를 체중증가량으로 비교하여 보면 Na-alginate($71\%$)가 가장 효과적이었고(P<0.01), 그 다음이 scordinin($76\%$), chlorella($76\%$), alliin($86\%$)의 순이었으며 (P<0.001), 사료효율로서 비교하여 보면 체중증가량과 마찬가지로 Na-alginate($68\%$)가 가장 효과적이었고(P<0.001), alliin($79\%$)도 그 효과가 인정되었다(P<0.05). 간장의 지방축적억제효과는 Na-alginate($84\%$)가 가장 효과적이었으며(P<0.001), 부역환 및 난소 주위의 지방조직에 있어서 지방축적억제효과는 Na-alginate($54\%$)가 가장 효과적이었으며 (P<0.001), 그 다음이 alliin($64\%$), saponin($66\%$)의 순으로 효과적임을 알 수 있었다(P<0.001). 또 Lee index에 의한 비만억제효과를 비교하여 보면 Na-alginate($91\%$)에서만 그 효과가 인정되었다(P<0.001). 간장중의 지방함량에 의한 지방축적억제효과를 비교하여 보면 alliin($40\%$)>saponin($58\%$)>Na-alginate($62\%$)>chlorella($64\%$)>scordinin($74\%$)의 순으로 효과적임을 알 수 있었다(P<0.001). 또 이들 성분들의 첨가에 의한 혈청 glucose 감소효과는 Na-alginate($67\%$)가 가장 효과적이었으며(P<0.001), 그 다음이 saponin($73\%$), scordinin($74\%$), alliin($83\%$)의 순으로 효과적이었다(P<0.001), 혈청cholesterol 저하작용을 비교하여 보면 Na-alginate($82\%$)가 가장 효과적이었으며(P<0.001), 그 다음이 alliin($84\%$), chlorella($86\%$), saponin($87\%$)의 순으로 효과적임을 알 수 있었다(P<0.001). 또한 혈청 lipase 활성의 증가에 의한 비만억제작용을 비교하여 보면, Na-alginate($109\%$)와 saponin($104\%$)의 첨가가 효과적임을 알 수 있었다. 따라서 미역, 다시마, 톳 등 갈조류성분인 알긴산이 담수녹조인 chlorella, 중요 생약인 인삼과 마늘의 유효약리성분인 saponin과 alliin 및 scordinin 보다 비만의 예방과 치료에 더 효과적임을 알 수 있었다.

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.

홍삼제품 제조 과정중의 부산물인 홍삼박의 활용 가능성을 조사하기 위하여 여러 가지 담자균의 배양에 홍삼박 추출물을 첨가하여 배양한 후 균체 증식량, 단백질 및 amino acid함량 등을 조사하였으며 그 결과를 보고하는 바이다. 수집 된 담자균 중 G. lucidum과 P. ostreatus가 액체배양에서 균체증식이 양호한 균주로 선발되었으며, 홍삼박 추출물을 0.2％ 첨가하였을 때 균체증식량이 가장 많았으며 단백질 함량은 0.5％ 첨가하였을 때 l-3％가 증가하였다. Amino acid함량은 인삼박 추출물을 0.2％ 첨가하였을 때는 거의 변화가 없었으나 0.5％ 첨가하였을 때에는 G. lucidum, P. ostreatus 모두 상당히 증가하였으며 그 증가폭 중 cysteine이 가장 컸다.

From crude drug preparation(Soshiho-Tang) ginseng sapogenins were identified by TLC and $ginsenoside-Rb_1$ was determined quantitatively by HPLC. Panaxadiol, pandaxatriol, acid-hydrolysates of ginseng saponin, were identified by TLC with benzene/acetone(4 : 1, v/v). Rf values of which were measured as 0.26 and 0.14, respectively. The content of $ginsenoside-Rb_1$ was determined by HPLC on $Lichrosorb-NH_2$ column with $CH_3CN/H_2O/n-BuOH$(80 : 20 : 10, v/v). Its recovery rate in the extract granules, was as relatively low as $19.8{\pm}1.4%$ compared to the content in raw red ginseng.
