  • Methanolic extracts of fifteen Chinese medicinal plants were screened for platelet-activating factor (PAF) receptor binding inhibitory activity using rabbit platelet. Campsis grandiflora, Dalbergia odorifera, Vaccaria segetalis and Zanthoxylum nitidum showed significant inhibitory effects on the platelet-activating factor (PAF) receptor binding. Campsis grandiflora, Dalbergia odorifera, Vaccaria segetalis and Zanthoxylum nitidum inhibited 52%, 56%, 70%, and 66% respectively at the concentration of 0.2 mg/ml.

  • The purpose of this study was to measure total phenolic compounds as a measure of antioxidant activity as well as ${\alpha}$-amylase inhibitory and ${\alpha}$-glucosidase inhibitory activities as a measure of anti-diabetic efficacy in methanol extracts from 23 kinds of medicinal plants. Extracts of three medicinal plant species showing high total polyphenol contents were selected (Euonymus alatus stem, Taxus cuspidata fruit, and Eucommia ulmoides leaf). Extracts of six medicinal plant species showing over 60% DPPH radical scavenging activity were also selected [Eucommia ulmoides barks (80.10%), Lycium chinense roots (64.25%), Euonymus alatus stem (73.59%), Lespedeza cuneata (78.20%), Taxus cuspidata fruits (70.52%), and Tilia taquetii leaf and stem (67.81%)]. Regarding ${\alpha}$-glucosidase and ${\alpha}$-amylase inhibitory activities acarbose showing approximately 80% inhibitory activity was selected as a control group, and six species (Eucommia ulmoides heartwood, Eucommia ulmoides bark, Euonymus alatus stem, Dioscorea batatas, Coix lachryma-jobi, and Phaseolus radiatus) showed greater than 80% ${\alpha}$-glucosidase inhibitory activity. Extracts of nine medicinal plant. species showing over 80% ${\alpha}$-amylase inhibitory activity (Pueraria thunbergiana root, Eucommia ulmoides bark, Eucommia ulmoides leaf, Lycium chinense fruits, Euonymus alatus leaf and stem, Euonymus alatus stem, Sasa borealis whole, Dioscorea batatas leaf and stem, and Tilia taquetii leaf and stem). Based on these results, medicinal plants showing high antioxidant and antidiabetic activities can be used as fundamental products in developing new medicines, as well as functional foods to prevent adult disease.

Effects of Supplemental Medicinal Plants (Artemisia, Acanthopanax and Garlic) on Productive Performance of Sows and on Growth and Carcass Traits in Finishing Pigs (약용식물(Artemisia, Acanthopanax and Garlic)의 급여가 돼지의 생산성에 미치는 영향)

  • This study was conducted to determine the effect of supplemental medicinal plants (Artemisia, Acanthopanx and Garlic) on productive parameters in pigs. In experiment 1, a total of 90 multiparous sows were used in a 21-d performance study. The diets included: 1) CON (basal diet; Control), 2) BM1 (CON + 0.1% medicinal plants) and 3) BM2 (CON + 0.2% medicinal plants). Backfat thickness from farrowing to weaning was higher (P<0.05) in CON compared with sows fed treatments diets. The piglets weight gain was higher in the medicinal plants treatments (P<0.05). ADFI, nutrient digestibility and survivability were not affected by the experimental treatments. In experiment 2, a total of 60 finishing pigs (Landrace ${\times}$ Yorkshire ${\times}$ Duroc, $65.21\;{\pm}\;0.04\;kg$ average initial body weight) were used in a 56-d performance assay to determine the effects of supplemental medicinal plants (Artemisia, Acanthopanx and Garlic) on growth performance and carcass characteristics in finishing pigs. The dietary treatments included: 1) CON (basal diet ; Control), 2) BM1 (CON + 0.1% medicinal plants) and 3) BM2 (CON + 0.2% medicinal plants). For 4~8 weeks and overall period, ADG was higher (P<0.05) in the pigs fed medicinal plants. CON treatment was higher 24 pH loin and cooking loss than BM1 treatment (P<0.05). Water holding capacity and drip loss after 1day were affected by the dietary treatments (P<0.05). No numerical differences were observed in sensory evaluation, meat color, TBARS and loin area among three treatments. In conclusion, the results obtained from this feeding trial suggest that the medicinal plants mixture supplementation in diets for finishing pigs can improve ADG, water holding capacity, cooking loss and it improved backfat loss in sow and, litter weight gain.
