This study was conducted to investigate the effects of supplemental medicinal herb mixture, laver powder and paprika powder in extruded pellet (EP) on growth and feed utilization of juvenile olive flounder. Triplicate groups of fish (average body weight of 19.6 g) were fed four experimental EPs containing 0.2% medicinal herb mixture (MHM), 1% laver powder (LP), 1% paprika powder (PP) and without supplementation (CON) for 9 weeks. Weight gain, daily feed intake, hepatosomatic index and condition factor were not influenced by dietary additives. Peed efficiency and protein efficiency ratio of flounder fed the diet containing laver powder were significantly higher than those of fish fed the medicinal herb mixture and paprika powder (P<0.05), but not significantly different from control group. The results of this study suggest that all tested additives in the dietary formulation did not affect growth and feed utilization of olive flounder.

To investigate the effects of soil acidification on growth of Impatiens balsamina L. plants were transplanted to acidified soils with H$_2$SO$_4$ solution. The concentrations of soluble Ca, Mg, K, Al and Mn in the acidified soils increased with increment of H$^{+}$ addition to the soil. In both species, the plant height and root length were inhibited by soil acidification, showing much severer inhibition in Impatiens balsamina L. than in Tagetes patula L., As the soil pH decreases, the growth of underground parts decreased greatly than that of above ground parts in both species. Total dry weight decreased with increased Al concentration as well as lowered soil pH in both plants. There was a strong positive correlation between relative total dry weight and molar (Ca+Mg+K) / Al ratio of the soil. The results suggest that molar(Ca+Mg+K)/ Al ratio of the soil may be useful indicator for assessing the critical load of acid deposition in herb species.s.

This study was conducted to evaluate the effects of dietary medicinal herb residues (MHR) on the growth and body composition of olive flounder (Paralichthys olivaceus). Two replicate groups of olive flounder with initial mean body weight of $18.7\pm0.3\;g$ were fed 8:2 (raw fish and commercial compound meal ratio)MP diet containing $0\%,\;50\%,\;10\%,\;15\%\;and\;20\%$ MHR for 7 weeks. Weight gain and feed efficiency increased in the $5\%\;and\;10\%$ group as compared to the control group, whereas they decreased in the $15\%\;and\;20\%$ groups. Moisture, crude protein, and crude ash content of the whole body were not significantly different between experimental groups, whereas crude lipid content of the $5\%\;and\;10\%$ groups were significantly higher than that of the $10\%\;and\;20\%$ groups. The results indicate that the addition of $5\%\;and\;10\%$ MHR in 8:2 MP diet can improve growth and feed efficiency, but addition of more than $15\%$ were not effective.

This study were conducted to investigate the effects of several additives in experimental diets on the growth, feed utilization and body composition of juvenile and grower rockfish. Three replicates of juveniles (3.6 g/fish) and two replicates growers (166 g/fish) were fed the experimental diets containing herb medicines mixture, Artemisia asiatica and Epimedium koreanum for 8 weeks. Dietary supplementation with herb medicines mixture had no beneficial effects on growth and feed utilization of juvenile fish. Weight gain, daily feed intake, condition factor and hepatosomatic index of grower fish fed the diet were not affected by dietary additive (P>0.05). Peed efficiency and protein efficiency ratio of grower fish fed the diet containing herb medicines mixture were significantly higher than those of fish fed the control diet (P<0.05), but not significantly different from fish fed the diet containing A. asiatica and E. koreanum (P>0.05). Proximate analysis of whole body, muscle, viscera and liver in the juvenile and grower were not affected by dietary additives (P>0.05). The results of this study suggest that feed efficiency and protein efficiency ratio of grower rockfish may improved by herb medicines mixture supplementation in the diet.

Purpose: This study was performed to evaluate the effects of sannamul or herb extract addition to a soybean oil-in-water emulsion during photooxidation in the presence of chlorophyll. Methods: The emulsion mainly consisted of purified soybean oil and citric acid buffer (pH 4.0) at a weight ratio of 4 to 6, with chlorophyll a addition at 6 mg/kg. Ethanol extract of daraesoon, samnamul, basil, or peppermint was selectively added to the emulsion at 400 mg/kg, and emulsions in glass serum bottles were oxidized at $5^{\circ}C$ under 2,600 lux light for 48 hours. Lipid oxidation of the emulsions was evaluated based on determination of headspace oxygen content, peroxide value, and p-anisidine value. Pigments and antioxidants were also monitored. Results: The emulsion with added samnamul extract with high contents of polyphenols and low chlorophyll content showed lower oxygen consumption, peroxide values, and p-anisidine values, whereas basil and peppermint extracts with high chlorophyll contents increased photooxidation. Chlorophylls were degraded during photooxidation of the emulsions, and the degradation rate was highest in the emulsion with added samnamul extract. Conclusion: The high antioxidant activity of samnamul extract in the photooxidation of soybean oil-in-water emulsion could be due to low chlorophyll content, high concentrations of polyphenol compounds in the extract, as well as rapid degradation of chlorophylls during oxidation.

This study was conducted to select proper substrate and nutrient solution concentration for favorable growth and quality in common thyme (Thymus vulgaris L.). The growth of common thyme was better in deep flow culture (DFT) than in other substrate cultures. As the nutrient solution concentration rose, the ratio of dry matter increased, while the fresh weight and the number of lateral shoots decreased. The contents of total chlorophyll and vitamin C were higher in DFT than others. Ca, K, P were showed high contents in cocopeat, but Mg content was the highest at half-fold concentration in DFT. Common thyme showed low content of nitrate in DFT compared with that in other substrate culture. DFT was the most effective system for pronoting growth and quality of common thyme. The optimal concentration of nutrient solution in common thyme was half-fold(EC=1.2mS/cm) of herbs nutrient solution by European Vegetable R&D Center.

In this study, to obtain icaritin with high pharmacological activities from icariin, which has a content ratio of over 58% in the total flavonoids of Epimedium herb, a special Epimedium flavonoid-glycosidase was produced, purified and characterized from Aspergillus sp.y848 strain. The optimal enzyme production was gained in a medium containing 5% (w/v) wheat bran extract and 0.7% (w/v) Epimedium leaf powder as the enzyme inducer, and strain culture at 30℃ for 6-7 days. The molecular weight of the enzyme was approximately 73.2 kDa; the optimal pH and temperature were 5.0 and 40℃. The enzyme Km and Vmax values for icariin were 15.63 mM and 55.56 mM/h. Moreover, the enzyme hydrolyzed the 7-O-glucosides of icariin into icariside II, and finally hydrolyzed 3-Orhamnoside of icariside II into icaritin. The enzyme also hydrolyzed 7-O-glucosides of epimedin B to sagittatoside B, and then further hydrolyzed terminal 3-O-xyloside of sagittatoside B to icarisiede II, before finally hydrolyzing 3-O-rhamnoside of icarisiede II into icaritin. The enzyme only hydrolyzed 7-O-glucoside of epimedin A or epimedin C into sagittatoside A or sagittatoside C. It is possible to prepare icaritin from the high-content icariin in Epimedium herb using this enzyme. When 2.5% icariin was reacted at 40℃ for 18-20 h by the low-cost crude enzyme, 5.04 g icaritin with 98% purity was obtained from 10 g icariin. Also, the icaritin molar yield was 92.5%. Our results showed icaritin was successfully produced via cost-effective and relatively simple methods from icariin by crude enzyme. Our results should be very useful for the development of medicines from Epimedium herb.
