  • The effect of the Ginkgoic acid on the amounts of total cholesterol and triglycerides in serum from rabbit was observed. Ginkgoic acid was obtained from Ginkgo biloba L. fruits, and it was subcutaneously administered to the three days fasted rabbits. After three days starvation, the amounts of total cholesteral and triglycerides in serum of the rabbit were markedly increased. The increased amounts of total cholesteral and triglycerides were gradually decreased by administration of Ginkgoic acid, and were returned to the control levels after 4 days. According to the above results, it would be concluded that Ginkgoic acid influences for the recovery of the increased amounts of total cholesterol and triglycerides by abnormal metabolism to normal on rabbit.

  • This study was carried out to prepare green teas by traditional roasting manufacturing process, Ku Geung Ku Po and to determine the quality charateristics of the green teas by examining the change of their main components induced during this roasting process. The content of total sugars in unroasted tea leaves was 7.82%. Its content of roasted teas was decreased by increasing the number of roasting and there was significantly differences between samples. The content of total sugars in 9th roasted green tea was 3.98%. The total nitrogen contents of green teas produced by this process were 4.96∼6.38%. The more the number of roasting and the less content of tannin in green teas. And the ratio of total nitrogen and tannin in tea leaves 21.97 but its ratio in 9th roasted tea was increased to 45.54. The ascorbic acid in tea leaves consisted in 1,820.3 mg/100g but its content was decreased by increasing the number of roasting process. Whereas the content of caffeine in green teas was not reduced significantly by this traditional method. Of all amino acids, green tea produced by Ku Jeung Ku Po was rich glutamic acid, lysine and aspartic acid. And especially, phenylalanine, which was rarely found in other green teas, was abundant in these green teas. The compositions of glutamic acid and methionine were increased as increasing the number of roasting process but those of aspartic acid and arginine decreased by these processing. The main fatty acids of Ku Jeung Ku Po green tea were linolenic acid, linoleic acid and palmitic acid and the contents of unsaturated fatty acid in green teas were composed over 70% of total fatty acid. And the fatty acid contents in green teas were not affected during Ku Jeung Ku Po's process. The contents of minerals in these teas was rich in the oder of potassuim. magnessuim and calciumim, and these contents were not observed the prominant change during the process.

  • In this study, we examined the antioxidant activity of the naturaceutical extract in vitro using total phenolic contents, total flavonoids contents, DPPH radical scavenging activity, reducing power assay, and phenolic acid contents. The total phenolic and total flavonoids contents of naturaceutical extract were 5.46 mg/g, 2.21 mg/g, respectively. The DPPH radical scavenging activity of natraceutical extract varied from 18.77 ($200{\mu}g/mL$) to 3.44 ($1,000{\mu}g/mL$). The reducing power of the natraceutical extract absorbance varied from 1.07 (0.78 mg/mL) to 3.44 (12.5 mg/mL), and reducing power of extract presented a concentration-dependent activity increase. The highest amounts of trans-ferulic acid, p-hydroxybenzoic acid, p-coumaric acid, vanillin, vanillic acid, p-hydroxybenzaldehyde, and trans-cinnamic acid were observed in the naturaceutical extract at the levels of 750.79, 619.75, 531.34, 222.04, 219.28, 107.40, and $89.56{\mu}g/g$, respectively. The results imply that this antioxidant effect of the naturaceuticals extract could be harnessed in the management and prevention of degenerative diseases associated with oxidative stress.

  • In order to find out the inhibitors of acetic acid fermentation in Korean ginseng (Panax Sin son C. A. Meyer), total aglycone, panaxadiol, panaxadiol, oleanolic acid and ${\beta}$ -sitosterol were added to the basal medium, respectively, and a surface culture was carried out at 30$^{\circ}C$. The results were as follows: 1 . Saponins lost their activity to inhibit the acetic acid fermentation by hydrolysis. 2 Panaxadiol inhibited slightly, and the degree of inhibition was about 1/300 of that of free saponins. 3. Panaxadiol and oleanolic acid inhibited silighly similar to total aglycone. 4. Acetic acid fermentation was stimulated at the early stage when ${\beta}$-sitosterol was added to the media below the level of 0.000815%. But the fermentation was inhibited when media contained it more than that media 5. An over-oxidation of acetic acid was observed when the media contained total aglycone. panaxadiol, panaxatriol, oleanolic acid and ${\beta}$-sitosterol, respectively, while the media which contained sucrose, ginseng extracts ginseng saponins was shown not to be over-oxidized.

  • Total lipid contents were 0.58∼3.00% in 9 kinds of brown algaes, 0.47∼2.16% in 5 kinds of red algaes and 0.55∼2.99% in 2 kind of green algeas, respectively. Fatty acid compositions of the algaes were determined by gas liquid chromatography. Total polyenes and n-3 polyenes of linoleic acid(18:3), stearidonic acid(18:4), eicosapentaenoic acid(20:5) and docosahexaenoic acid(22:6) were 3.88∼57.57% and 1.46∼25.67% in the brown algaes, 5.30∼39.75% and 1.17∼21.91% in the red algaes, and 7.76∼19.27% and 3.67%∼10.61% in the green algaes, respectirely. The fatty acid contents and compositions of total polyenes and n-3 polyenes were vary different in the algae groups and sepecies.

  • Total mixed ration (TMR) including concentrate diet and roughage together have been used for the ruminant animal. Relatively high concentrations of moisture and water soluble carbohydrate are representative feature of TMR. Those moisture and water can also provide a niche for bacterial growth. Therefore, a possible fermentation of TMR induced by micro-organism is generally accepted. The present study hypothesized that different lactic acid bacteria could alter fermentation of TMR and subsequently rumen fermentation. Three lactic acid bacteria, Lactobacillus paracasei (A), L. plantarum (B) and L. parabuchneri (C), were employed and 7 treatments under full factorial design were compared with control without inoculation. TMR for dairy cow was used. Significant alterations by treatments were detected at lactic acid and butyric acid contents in TMR (p<0.05). Treatment AC (mixture of A and C) and BC (mixture of B and C) showed great lactate production. Great butyrate production was found at treatment C. At in vitro rumen fermentation, treatments B, C and AB (mixture of A and B) showed significantly great total gas production (p<0.05). All treatments except treatments B and AB, showed less dry matter digestibility, significantly (p<0.05). Total volatile fatty acid production at treatment AC was significantly greater than others (p<0.05). In individual volatile fatty acid production, treatment AB and AC showed great acetate and propionate productions, significantly (p<0.05). This study investigated correlation between organic acid production in TMR and rumen volatile fatty acid production. And it was found that butyric acid in TMR had significant negative correlation with acetate, propionate, total volatile fatty acid, AP ratio and dry matter digestibility.
