The root of Astragalus membranaceous (AM) has been used to treat edema and arthritis in the traditional Korean medicine. To elucidate the anti-inflammatory and anti-nociceptive effects of ethanol extract of AM, the carrageenan-induced paw edema using a plethysmometer and thermal hypersensitivity using the plantar test were measured. Ibuprofen was used as a control drug. Pretreatment with AM (400 mg/kg p.o.) significantly reduced paw edema, compared to the carrageenan-treated rats. In the plantar test, the thermal withdrawal latency in AM-treated group was significantly increased than the carrageenan-treated group. The results indicate that AM could have be the anti-inflammatory and anti-nociceptive properties.

It was previously reported that red ginseng extract inhibited carcinogenesis by urethan, DMBA and aflatoxin $B_1E (Cancer Detection and Prevention, 6: 515-525, 1983). In an attempt to investigate the mechanism of the anticarcinogenic effect of ginseng, we assayed natural killer (N.K) activity in mice treated with urethan and benzo(a)pyrene. In our experiment newly born Swiss Webster mice, less than 24 hrs. old, were given a single subcutaneous injection of lmg of ure-than and 40ug of benzo(a)pyrene. The mice had been administered with ginseng since weaning, and sacrificed at various intervals. Major organs were examined both, with the naked eye and microscopically. N.K. activity of spleen cells was analyzed in a 12-hour $^{51}Cr^-release$ assay against YAC-1 cells. Administration of ginseng resulted in an increase of N.K. activity by $18\%$ at 4 weeks, $20\%$ (P < 0.05) at 6, $29\%$ (P < 0.05) at 12, and $13\%$ at 24 following a single injection of urethan. At the same time, significantly lower incidences of lung adenoma were noted at 6 weeks $(50\%)$ and 12 weeks $(27\%)$ following the administration of ginseng to urethan-injected mice. This result indicates that the enhancement of N.K. activity by ginseng makes a contribution to its anticarcinogenic effect. On the hand, N.K. activity was suppressed by benzo(a)pyrene during the time span of this experiment and it almost returned to the level of controls following the adminsitration of ginseng. However, the lung adenoma induced by benzo(a)pyrene began to occur at 48 weeks in which N.K. activity had naturally declined to a very low level in all experimental mice, and administration of ginseng did not decrease the incidence. In explanation of this result, we might propose that the recovery of the N.K. activity by ginseng had little effect on the incidence of lung adenoma because of the long latent period of carcinogenesis by benzo(a)pyrene. In conclusion, these results suggest that the anticarcinogenic effect of ginseng in urethan-treated mice may be related to the augmentation of N.K. activity.

The objective of this study was determined to evaluate ${\alpha}$-amylase, ${\alpha}$-glucosidase, pancreatic lipase inhibition in vitro and DPPH radical scavenging activity of the several Korean resources plants. The ${\alpha}$-amylase inhibitory activity of Salicornia herbacea, Erythronium japonicum (flower) and Phragmites communis (root) in water extract showed relatively high 62.8%, 66.5% and 69.3%, respectively. The ${\alpha}$-amylase inhibitory activity of Citrus junos (pericarp) and Cornus officinalis in methanol extract was found to have an effect with 32.8% in Citrus junos (pericarp) and 60.9% in Cornus officinalis. Corylopsis coreana in both water and methanol extract had the highest ${\alpha}$-glucosidase inhibitory activity of 81.7% and 89.5%, while the extract of Portulaca oleracea, Ficus carica and Citrus junos was not measured ${\alpha}$-glucosidase inhibitory activity at given experiment concentration. Depending on the extraction solvent and the plant species, it was observed that there was a significant difference in ${\alpha}$-glucosidase inhibitory activity. The pancreatic lipase inhibitory activity showed relatively higher in the methanol extract than water extract except pericarp of Citrus junos. The DPPH radical scavenging activity of selected plants was much difference between measured plant species, and showed that the increase was proportional to the concentration. These results suggested that selected plants had the potent biological activity on carbohydrate, lipid Inhibitory activity and antioxidant activity, therefore these plant resources could be a good materials to develop medicinal preparations, nutraceuticals or health functional foods for diabetes or obesity.

As a fundermental research for quality stailization of herb extract, the effects of water activity on microbial growth in herb extract were investigated. Herbs-Panax ginseng, Cinnamomum cassia, Lycium chinense, Zyzyphus jujuba, Lindera obtusilobum-were mixed and extracted with water at $80^{\circ}C$ and concentrated at $75^{\circ}C$. Water activity of the herb extract was adjusted to 0.86, 0.80 and 0.69, using water activity analyzer. The extracts were incubated for 180 days at $40^{\circ}C$ and then examined microbial cell counts and some physicochemical properties. In the extract of $a_{w}$ 0.86, 18 CFU/g of initial viable cell was increased to 80 CFU/g with 90 days of incubation and to 190 CFU/g 180 days of incubation. In the extract of $a_{w}$ 0.80, 24 CFU/g of initial viable cell was also increased to 83 CFU/g during the 90 days of incubation and to 170 CFU/ g for the 180 days of incubation. However, in the extract of $a_{w}$ 0.69, viable cell after 180 days of incubation was remained at almost the same level as initial viable cell. pH of herb extract was reduced in proportion to the decrease in water activity. The TLC (thin layer chromatography) patterns of ginseng saponins of herb extract did not show any significant changes after 180 days of incubation. Growth of pathogenic microorganisms was inhibited more with lower water activity of the herb extracts. In the herb extract inoculated with Candida albicans and Aspergillus niger, initial viable cells of 150 and 140 CFU/g were decreased to 30 and 20 CFU/g, repectively, after 30 days of incubation at $28^{\circ}C$. In the case of herb extract inoculated with Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa, growth of the bacteria was totally inhibited even after 30 days of incubation at $37^{\circ}C$.

Ginseng root, as a folk medicine, has been used in far eastern countries for thousands of years. Ginseng extract has been shown to have a variety of effects on the activity of the central nervous system, promoting stimulation as well as inhibition of the cortical activity. A survey of the relevant literatures has indicated that the putative anxiolytic activity of red ginseng has not been scientifically investigated. Therefore, the present study was designed to assess anxiolytic effect of gingseng total saponins(GTS). The putative anxiolytic effects of several fractions of GTS were investigated in mice using an elevated plus maze paradigm. Single dose administration of TS Fr.-I showed anxiolytic action in mice. Anxiolytic effect induced by TS Fr.-I was similar to that induced by diazepam. TS Fr.-II, TS Fr.-III and TS Fr.-IV did not show the anxiolytic action compared with that of TS Fr.-I. It was suggested that regulation of GABAergic neurotransmission may be important in the action of GTS. The Interaction of GTS fractions with benzodiazepine receptor was performed using rat cortical membranes. GTS inhibited the binding of [3H] Ro 15-1788 on the benzodiazepine receptor. Among from TS fractions, the binding activity of GTS in the TS Fr.-IV was highest, which did not show the anxiolytic activity. From these results, we conclude that GTS has anxiolytic action, and this is not related to benzodiazepine receptor binding activity.

To analyse components of fresh ginseng and some white ginsengs with different processing conditions, approximate composition, extraction yield, total saponin content and composition and free sugar composition of fresh ginseng, white ginseng, Taeguksam A and Taeguksam B were examined. Yield of hot water extraction was two times higher than that of 80% methanol extraction. Hot water extraction yields of fresh ginseng, white ginseng, Taeguksam A and Taeguksam B were 56.4, 39.9, 42.9 and 46.6%, respectively, while the 80% methanol extraction yields ranged from 15.8% to 21.9%. Total saponin contents of the above were 2.40, 1.73, 1.45 and 1.79%, respectively, with hot water extraction and were 2.15, 2.99, 2.81 and 2.35%, respectively, with 80% methanol extraction. Ginsenoside compositions of the above varied with processing conditions and extraction solvents. Hot water and 80% methanol extracts of fresh and white ginseng composed of fructose, glucose, sucrose and maltose. Rhamnose was detected only in the extract of Taeguksam A and B.

This study examined the effects of the dietary inclusion of various concentrations of red ginseng byproduct (RB) and a mixture containing red ginseng byproduct, garlic extract, yeast and filler (CR) on the growth, body composition, serum chemistry, and lysozyme activity of juvenile olive flounder (Paralichthys olivaceus). Juvenile fish (n= 630) weighing 5.0 g were randomly distributed into 21 180 L flow-through tanks (30 fish/tank). Seven experimental diets were prepared in triplicate: a control diet without additive, and diets containing 0.5, 1 and 2% concentrations of RB (RB-0.5, RB-1, RB-2) and CR (CR-0.5, CR-1, CR-2) at the expense of wheat flour. After an 8-week feeding trial, serum chemistry and lysozyme activity of fish were measured. Mean weight gain was significantly higher in fish fed the control diet than in fish fed the RB and CR diets. The dietary inclusion of RB and CR reduced feed utilization. Mean serum glucose and triglyceride (TG) levels were higher in fish fed the control diet than in fish fed the other diets. Mean glutamate pyruvate transaminase (GPT) levels of fish fed the control and RB-2 diets were higher than those of fish fed the RB-0.5, RB-1, CR-1, and CR-2 diets. Mean lysozyme activity levels of fish fed the RB-0.5 and RB-1 diets were higher than those of fish fed the control and CR diets. The results of this study indicate that red ginseng byproduct may be utilized as an immunostimulant rather than as a growth promoter for juvenile olive flounder. Dietary inclusion of 0.5% red ginseng byproduct effectively improved serum glucose, GPT, TG, and lysozyme activity of the fish in this study.

The free fatty acids were prepared from the ethereal fraction of Panax ginseng. The prepared acids were methylated with diazomethzne. The methyl esters of saturated and unsaturated fatty acids were separated by the means of mercuric acetate method and column chromatography. The separated methyl esters were gaschromatographed and analyzed. The obtained conclusions were as follows. 1. The root of six-year old Korean Panax ginseng contains 0.28% of free fatty acids. 2. It was found that 24 kinds of free fatty acids existed in Panax ginseng. Among them, 22 kinds of free fatty acids were indentified by the gas chromatogram and the graphical method but the rest, 2 kinds of them were not identified by the only gas chromatographical data. The amount of each free fatty acid which was not identified was predominant and they were supposed to be unusual free fatty acids which would not commonly exist in nature. These results were shown in Table III. 3. $L_{EE}$ and $L_{EE}$ reported that n18:3 existed in Panax ginseng. However, in this experiment, n18:3 did not exist in Panax ginseng, and instead, peak XVI appeared between n18:2 and n18:3 as shown in Fig. 9.
