  • This study reports the identification of species of Colletotrichum strains originating from red-pepper and Chinese matrimony vine in Cheongyang. Ninteen isolates of red-pepper and 26 Coiletotrichum isolates of Chinese matrimony vine were compared with 5 isolates of strawberry representing C. gloeosporioides, by use of morphological and cultural criteria. Twenty three isolates among 26 isolates from Chinese matrimony vine were identified as C. acutatum, characterized by the low growth rates and the low sensitivity to carbendazim and diethofencarb. Also, all the isolates of red-pepper were identified as C. acutatum, showing the same characteristics as those of Chinese matrimony vine. Three and five isolates from Chinese matrimony vine and strawberry, respectively, were identified as C. gloeosporioides, characterized by the high growth rates and the high seneitivity to carbendazim and diethofencarb. There were differences in colony color and pathogenicity between Chinese matrimony vine isolates and red-pepper isolates of C. autatum. The isolates of C. acutatum from Chinese matrimony vine producing orange colored colonies with abundant spores showed the strong pathogenicity to Chinese matrimony vine, although they could not infect fruits of red-pepper by the wound inoculation. However, red-pepper isolates of C. acutatum producing gray colonies showed the strong pathogenicity to Chinese matrimony vine as well as red-pepper. Furthermore, comparative study on PCR amplification of ITS regions of rDNA was carried out using a number of Colletotrichum isolates. A species-specific primer could be used for the identification of C. acutatum from red-pepper and Chinese matrimony vine.

  • A fungus, Colletotrichum fioriniae, was isolated for the first time from fruits of Chinese matrimony vine (Lycium chinense Mill.) in Korea. It was classified as C. fioriniae based on the morphological characteristics and nucleotide sequence of glyceraldehyde-3-phosphate-dehydrogenase and ${\beta}-tubulin$. To the best of our knowledge, this is the first report of C. fioriniae causing anthracnose of Chinese matrimony vine in Korea.

  • Background : Chinese matrimony vine (Lycium chinense Mill.) is a deciduous shrub belonging to the Solanaceae. The leaves are used as an alternative raw material replacing dried fruits associated with high production costs in many industires. The aim of this experiment was to determine the effect of drying temperature on the leaves used in the manufacture of functional products. Methods and Results : The leaves of Chinese matrimony vine were harvested when the plant height reached 60 - 70 cm in the spring and treated at four different temperatures ($40^{\circ}C$, $50^{\circ}C$, $60^{\circ}C$ and $70^{\circ}C$). The time to reach the desiccation state of 20% was 63 h at $40^{\circ}C$, 37 h at $50^{\circ}C$, 17 h at $60^{\circ}C$ and 11 h at $70^{\circ}C$. The drying rate per hour was 1.28% at $40^{\circ}C$, 2.25% at $50^{\circ}C$, 4.94% at $60^{\circ}C$ and 7.60% at $70^{\circ}C$. No significant difference were observed in ash, crude fat, polyphenol or rutin content of treated samples. Crude protein and betaine content decreased with higher dry temperatures. Nitrogen free extract of the treated samples increased with higher drying temperatures. Conclusions : Taking into consideration drying time, drying rate, color value, energy consumption and functional ingredients is advantageous to dry the leaves of the Chinese matrimony vine at $60^{\circ}C$ using a hot air agricultural dryer.

  • 구기자에 등록되어 사용중인 triadimefon과 triforine, 대추에 등록되어 사용되고 있는 methoxyfenozide와 thiacloprid의 건조에 따른 농약 잔류량의 변화를 확인하기 위해 분무와 침지방법으로 구기자와 대추에 농약을 처리한 후 건조하였다. 건조 전후의 구기자와 대추의 수분함량을 측정하였으며, GLC-ECD와 HPLC-DAD를 이용하여 잔류농약을 분석하여 건조에 의한 가공계수와 수분보정에 의한 감소계수를 산출하였다. 건조에 의한 구기자 중 triadimefon과 triforine의 가공계수는 각각 1.41-1.81와 1.70-2.28이었고, 대추 중 methoxyfenozide와 thiacloprid의 가공계수는 각각 3.35-4.20와 1.50-1.89으로 잔류농도가 증가하였다. 그러나 구기자와 대추 중 시험농약의 건조에 따른 감소계수는 구기자의 triadimefon과 thiacloprid는 각각 0.29-0.35와 0.33-0.47, 대추의 methoxyfenozide와 thiacloprid의 경우는 각각 0.75-0.98과 0.68-0.87로써 건조에 의한 시험농약의 절대량은 감소하였다.

  • The objective of this study was to investigate the effect of alcohol content in Makgeolli made with Chinese matrimony vine (M-CMV) on the sensory profile and consumer acceptability. The M-CMVs were prepared with 6, 7, 8, and 9% alcohol content. Descriptive analysis of M-CMV was performed with six trained panelists. Thirteen attributes were generated and their intensities were alcohol content dependent. The consumer acceptance test was conducted with 57 consumers. M-CMV samples with 7% alcohol had the highest acceptance rate (5.8) followed by 6% M-CMV (5.6). Commercial rice Makgeolli (CRM) had the lowest consumer acceptance. Consumers were divided into two groups by clustering analysis. The majority of consumers (n=38) preferred M-CMV and did not like the commercial sample. Only 19 consumers indicated high acceptance ratings for CRM. However, these consumers also preferred 6 and 7% M-CMV. Partial least-squares regression analysis revealed moderate attribute intensities were related to greater consumer acceptability. The optimal alcohol content for the greatest consumer acceptance predicted by linear regression was 6.7%.

  • This study was performed to evaluate the possible production of a functional beverage derived from abalone and with several plants (AP). Five types of AP composites were prepared having different medicinal plant compositions (AP- I : abalone, garlic, jujube, Chinese matrimony fruit, dried orange peel, licorice root, zinger, honey; AP- II: abalone, garlic, black bean, Chinese matrimony fruit, cornus fruit, licorice root, zinger, honey; AP-III : abalone, jujube, arrow root, milk vetch, dried orange peel, licorice root, zinger, honey; AP-N: abalone, black bean, arrow root, milk vetch, cornus fruit, liquorice root, zinger, honey; AP-V : abalone, garlic, Chinese matrimony fruit, milk vetch, licorice root, zinger, honey). In vitro analysis were performed to examine the antioxidant contents and alcohol dehydrogenase activities of the composites. AP- II had the highest total phenol contents ($28.55{\pm}1.56\;mg/l00\;g$), and AP- V the highest level of flavonoids ($47.61{\pm}1.58\;mg/l00\;g$). At $78.89{\pm}0.16%$, AP- V displayed the strongest electron donating ability followed by AP-II($57.99{\pm}0.21%$) and API ($37.66{\pm}0.20%$). Reducing power was also significantly higher in AP- V. The Hydroxyl radical scavenging and SOD-like activities of all composites were less than 15% and 20%, respectively. At 12.5% alcohol concentration, ADH activity ranged from $114.47{\pm}2.18{\sim}121.39{\pm}4.36%$ and ALDH activity ranged from $100.04{\pm}2.90{\sim}129.54{\pm}4.80%$; AP- I , AP- II, and AP- Vin 12.5% of alcoholic concentration. The composites of AP- I , AP- II, and AP- V, all containing garlic and Chinese matrimony fruit, were significantly stronger than AP-III and AP-N. Finally, also at 12.5% alcoholic concentration, the ALDH activity of AP- V was higher than its ADH activity.

  • BACKGROUND: This study was carried out to determine characteristics of residual pesticides in time-dependent manner and calculate half-lives of the residual pesticides in fresh and dried Chinese matrimony vine. In addition, processing factors were calculated based on the residual concentrations in them. METHODS AND RESULTS: The test pesticides, etofenprox and fenitrothion, were sprayed onto the Chinese matrimony vine plants at once or twice (at seven-day interval) and then samples were collected at 0 (after 3 hours), 1, 3, 5 and 7 days after the last spraying. Dried samples were prepared in hot-air drying oven at $60^{\circ}C$ for 48 hours until water content of less than 20%. Residual concentrations of etofenprox in fresh and dried samples decreased by 54.0-60.9% after 7 days of the last pesticide-application. In case of fenitrothion, the concentrations were found to have decreased by 69.2-76.5%. Processing factors of etofenprox were 2.6-3.0 for the one-time spraying and 2.5-3.0 for the two-time spraying and those of fenitrothion were found to be 1.5-22 for the one-time spraying and 1.6-2.0 for the two-time spraying. First half-lives of etofenprox and fenitrothion in fresh and dried samples ranged from 5.0 to 6.3 and from 3.4 to 4.0 days, respectively. The third half-lives were found to be 15.0-18.9 and 10.2-12.1 days, respectively. CONCLUSION: Residual concentrations of the tested pesticides in the studied crop decreased, but those in the dried samples appeared to have increased. In addition, processing factor and half life were constant regardless of spraying times.
