  • Physical characteristics of stem (ile., length and diameter) and branch, and detachment force of mature and immature fruits of 12 species of the Lycium chinese Mill at a cultivar were determined. The number of stems and branches were counted after the first and second pruning of each plant. Length and diameter of the stem were average of 113.5 cm and 9.5 mm for 12 species of the Lycium chinese Mill, respectively. Average number of stem and number of branch after the first and second pruning in each plant were 5, 30, and 61, respectively. Diameter of major and minor axis of the fruit was average of 13.8mm and 8.3mm, respectively, and the sphericity of fruits was average of 0.7 for 12 species of Lycium chinese Mill. Detachment force of mature and immature fruits was average of 1 N and 2.7 N, respectively, for 12 species of the Lycium chinese Mill. The maximum and minimum detachment force of the mature fruits was 2.06 N and 0.39 N, respectively, and that of the immature fruits was 3.72 N and 1.27 N, respectively. The force-weight ratio showed a decreasing trend as the weight of fruit increasing for all samples.

  • This study was carried out to investigate the effects of planting density, time and frequency of pinching on growth and yield of Lycium chinese Miller cultivated in vinyl house. This experiment was conducted at the experimental field of Cheong-yang Agriculture High School, Cheong-yang, Chung-nam province, in 1997 to 1998. The number of flowers, fruit setting number and dry weight of fruits per branch were increased as the spacings were wider, but the fruit yield per unit area was decreased up to the narrowest spacing plot of $60\;{\times}\;20cm$. The good results of growth status and fruit yield was obtained at the early pinching in May 5. As the more frequent pinching were treated, the more number of flowers and fruits per branch were produced, showing increase of fresh and dry yield, because of much more branches per plot.

  • We previously reported that a novel cerebroside, LCC, isolated from the fruits of Lycium chinense (Solanaceae), significantly exerted hepatoprotective activity against both the carbon tetrachloride-induced and galactosamine-induced toxicities in primary cultures of rat hepatocytes. In the present study, we further attempted to determine the effect of LCC on hepatic fibrosis in animal model. Hepatic fibrosis was induced in rats by bile duct ligation/scission (BDL) for a period of 5 weeks. Treatment of BDL rats with LCC significantly reduced collagen deposition and the activities of serum alkaline phosphatase and ${\gamma}$-glutamyl transpeptidase. In addition, the LCC treatment of BDL rats significantly preserved the decreased hepatic glutathione as well as the activities of glutathione reductase and catalase in BDL rats. From the results, it can be speculated that LCC might exert antifibrotic activity in rats with BDL, in part, through the preservation of antioxidant enzymes and hepatic glutathione.

  • The florescence steps of Lycium chinense M. are as follows: Budding-Yellow, leaf-Falling-Flowering. Pruning treatment has a long stem diameter compared withnon-pruning treatment and as a result, the numbers of internode were great and thetotal effective numbers of branch were great, too. In the non-pruning treatment asthe fruit length was short so the fruit was small, and on the contrary in the pruningtreatment as the fruit length was long so large and good fruits were produced.Fresh fruit weight produced per 10a was increased as much as 38-39% in thesurface pruning treatment and in the pruning treatment l0Cm away from surfacecompared with in the non-pruning treatmerlt.

  • The bioactivities of boxthron fruits, a source of oriental medicine, are well known, whereas phytochemical studies of the boxthorn stem are rare. In this study, the stem extract of boxthorn (Lycium chinense Miller) and its subfractions were evaluated for their effects on nitric oxide (NO) inhibition and procollagen type I peptide (PIP) synthesis. A phenolic amide isolated from the stem extract was also assayed for these effects. The compound, N-trans-feruloyltyramine, was identified by $^1H$, $^{13}C$, and 2D-nuclear magnetic resonance analyses. In NO inhibition, the chloroform fraction (CF) exhibited the strongest inhibitory activity ($MIC_{50}=24.69{\mu}g/ml$) among the subfractions of the ethanol extract (EE). N-trans-feruloyltyramine isolated from the CF showed strong NO inhibitory activity, presenting with an $MIC_{50}$ of $31.36{\mu}g/ml$. The EE, CF, and N-trans-feruloyltyramine shown to have NO inhibition activity were assayed for the activity of PIP synthesis. The EE and CF showed relatively high PIP values of 38.8% and 24.21% at $100{\mu}g/ml$, respectively. The PIP value for $20{\mu}g/ml$ N-trans-feruloyltyramine showed a 36% increase compared with the non-treated control, whereas that treated with $20{\mu}g/ml$ ascorbic acid as a positive control showed a 13% increase. The results suggest that the proper stem extract of boxthorn stem could be efficiently used to produce good cosmetic effects.

  • Kugija was added to Nabak kimchi to improve the quality and preservation and the optimum addition level was assessed. Kugija extract was prepared by boiling kugija fruits, at different ratios (0, 1, 3, 5, 7%; w/v) in water for 30 minutes. The changes in the physicochemical properties of the Nabak kimchi were measured during storage for 25 days at 10?, and compared to a control (without kugija). The pH was decreased in all treatments. Following the fermentation of Nabak kimchi, the total acidity values were inversely proportional the pH changes according to the nature of mutual dependence. However, in short term, during the initial 7 days of fermentation, the total acidity values decreased with increasing concentrations of kugija extract, whereas the trend was reversed after day 10. Total vitamin C content was directly proportional to the concentration of kugija extract and was decreased with the laps of fermentation. Up to day 25, 7% treatment showed the highest vitamin C content, but at 25 days 1% and 3% treatments ranked the first. The mont of reducing sugar was proportional to the concentration of kugija extract however, the difference of values between all treatments became almost indiscernible after day 25. Turbidity values were generally increased in all samples during fermentation period, although only to a limited extent. The lowest turbidity was shown at 3% treatment up to day 16. Total color difference values were increased up to day 16, but then decreased. The optimum level of kugija extract in Nabak kimchi, as determined through these experiments, was between 1 to 3% per added water content, and was preferably 3% for color and fermentation-retarding effect of the product. Kugija extract could be applied for improving the quality and preservation of traditionally prepared Nabak kimchi.
