  • Flacherie virus (FV) and Densonucleosis virus (DNV) of the silkworm, Bombyx mori, which give the most severest damage to the silk production in korea, were fed on the mulberry wild silkworm, Bombyx mori mandarina, the mulberry pyralid, Gryphodes phyloalis, and the American fall webworm, Hypantria cunea, to investigate cross infectivity by serological and histopathological at observation. By the Ouchterlony's double difusion test the mulberry wild silkworm was infected with both FV and DNV type 1 (DNV-1) and the mulberry pyralid with DNV-1, so those were confirmed the cross infection. But the American fall webworm was not recognized the cross infection by the same method. The infection and multiplication of the FV in the mulberry wild silkworm was observed in the cytoplasm of the goblet cell with the appearance of the virus-specific vesicle. In DNV-1 infection to the mulberry wild silkworm and the mulberry pyralid, the nuclei of columnar cell in the midgut of both insects was hypertrophied and the nuclei of midgut cell of the mulberry pyralid positively stained with the feulgen stain. Multiplication of DNV-1 in the midgut cell of the mulberry wild silkworm was replicated in two different patterens as linear arrays and large masses, while that of DNV-1 in the muberry pyralid was multiplied as virus masses in several portion of the nuclei of the midgut cell.

  • The antioxidant activities and flavonoid contents of the mulberry leaves and the ginko leaves teas were investigated. The antioxidant activities were examined by FRAP and DPPH radical scavenging assays, and total phenolic content and the flavonoid contents by HPLC were also determined. The ginko leaves tea showed the highest antioxidant activities and antioxidant contents, while the wild mulberry leaves tea showed the lowest. The antioxidant activities of the mixture tea of wild mulberry leaves and ginko leaves were increased more than the wild mulberry leaves tea. The flavonoid contents of the leaves(ginko, wild mulberry and mixture) powders were higher than those of infusion teas. Compared with wild mulberry tea, the mixture tea showed a little increase of flavonoid contents. The total phenolic contents and the flavonoid contents of the teas showed good correlations with their antioxidant activities, such as FRAP and DPPH radical scavenging activities(${\geq}0.8727$). The antioxidant capacities of wild mulberry leaves tea could be enhanced by the addition of the ginko leaves.

  • Sencory characteristics of mulberry fruit jam and wine were investigated by according to mulberry fruit varieties, including Daeryukppong, Kuksang 20, Chongilppong and a wild mulberry variety. Palatability ranks of mulberry fruit jam by according to mulberry fruit varieties were Kuksang 20(34.5%), Chongilppong(32.8%), Daeryukppong(17.2%) and Wild variety(15.5%). In the sensory characteristics, we obtained 6.32 points as total mean point. In case of mulberry fruit wine, panels were favorits the Chongilppong best. But, in the sensory characteristics, we obtained low points(=5.47) as total mean point. From these results, it seems that alcohol content was very important factor. We selectd two desirable mulberry fruit varieties(=Chongilppong and Kuksang 20) for manufacturing materials.

  • This study was carried out to investigate the mineral content in the regional, varietal and seasonal mulberry leaves. On average, mulberry leaf samples contained minerals in the order of potassiumi phosphorus, calcium, magnesium, iron and so on (2.494 g/100 g, 2.255 g/100 g, 1.835 g/100 g, 0.627 g/100 g, 0.0245 g/100 g DW, respectively). Calcium content was 19-fold and 4-fold higher than that of green tea and spinach, respectively, suggesting that mulberry loaves appear to be a calcium-rich food source. In the comparison of geographic samples of Cheongilppong variety, calcium bevel was highest in Youngchun sample (2.477 g/100 g) and highest potassium level in Suwon sample (2.962 g/100 g). In the geographic samples of YK209 variety, Jinju-City sample was highest in calcium content (1.509 g/100 g). Among wild mulberry loaves collected from Cheju Island and Tsushima, potassium level was highest in Bongge-dong, Cheiu City (3.865 g/100 g) and calcium level in Mitshshima Town, Tsushima (2.948 g/100 g). In the comparison of varietal samples collected in Suwon at the mulberry field of Dept. of Sericulture & entomology, Shinkwangppong variety was highest in the potassium levels although Keryangppong and Shinkwangppong were higher in calcium revel. In the comparison of seasonal samples of Cheongilppong, there was a rough trend of increase in some minerals up to July (e.g., calcium rind )potassium). Finding of the highest calcium and potassium contents in the wild mulberry (3.865 g/100 g and 2.948 g/100 g, respectively) rather than in the cultivated ones warrant that more focus should be paid to wild mulberry leaves to utilize their minerals effciently.

  • We conducted this study to investigate the morphological characteristics and physiological effects of mulberry leaves and fruits with wild varieties. Morphologically sampling materials were showed Morus bombycis type and Morus alba type characteristics. Water contents of mulberry fruits were higher than that of mulberry leaves. Sugar degree of sampling materials was 5.1∼22.7 Brix %. The yield of 85% MeOH extract from freezing dried Mulberry Fruits was 60.2% and Hexane, BuOH and H$_2$O fraction from MeOH extract were 2.8%, 4.6%, 92.3% respectively. In the cholesterol-induced hyperlipidemia rats administered with subfraction of mulberry fruit extract, total cholesterol and serum triglyceride were decreased in the MeOH extract group and H$_2$O soluble fraction group. Also H$_2$O soluble fraction group decreased GPT, GOT and LDH level. Therefore, the above results suggested that mulberry fruit with wild varieties can help to maintain normal liver functions and to protect hyperlipidemia.

  • Resveratrol is naturally occurring phytoalexin compounds produced by grape berries, peanuts, pine tree, mulberry fruits and their products in response to stress such as fungal infection, heavy metal ions or UV irradiation. The objective of this study was to determine resveratrol contents in wild-type mulberry leaves (Morus alba L., M. bombycis Koidz, and M. Lhou (Ser.) Koidz) collected from Won-ju, In-je and Yang-yang regions, Gangwon province, Korea. Resveratrol contents in wild-type mulberry leaves were higher in Autumn's than in Spring's, and higher than 16 cultivar's. Among the samples, 'No. 3', collected from Won-ju region and 'No. 7' collected from In-je showed high resveratrol contents of 539 and $491{\mu}g$/100 g DW (dry weight; DW), respectively, through the collection time. Therefore, two mulberry trees might be promising as potent resources for mulberry breeding and functional material development.
