  • Black sooty mould fungus was observed on the upper side of the mulberry leaves caused by the Capnodium sp. This fungus develops with the utilization of the honeydew dropped by the whiteflies. Few selected insecticides like Monocrotophos, Chloropyriphos and Nuvan were tried to control the whitefly incidence and followed by the application of Maida (wheat flour paste) and Starch solution separately to control the incidence of the Capnodium on mulberry. It is found that a significant control of the whitefly incidence with the application of Nuvan (2 $m\ell$/L) and followed by Chloropyriphos (2 $m\ell$/L) and Monocrotophos (1.6 $m\ell$/L) and also a significant control of sooty mould infection were recorded with Starch and Maida application.

  • Effects of calcium on mulberry growth and freezing tolerance were examined by water culture. Calcium was supplied by folar spray with the levels of 0, 5, and 40 ppm. Muberry stems developed by 130 cm at Ca2+ 40ppm, 82 cm at Ca2+ 5 ppm and 23 cm at Ca2+ 0 ppm. Muberry roots also developed vigorously at Ca2+ 40 ppm, but did poorly at Ca2+ 5 ppm and changed to brown in color, and died becoming necrosis at Ca2+ 0 ppm. Content of calcium in leaves and barks were increased at Ca2+ 40 ppm compared with at Ca2+ 5 ppm. Total sugar, RNA, proline and phospholipid at Ca2+ 40 ppm were also more increased than those at Ca2+ 5 ppm. Mulberry stems grown at Ca2+ 40 ppm showed a sufficient tolerance at -10 for 24 hours while stems grown at Ca2+ 5 ppm did a weak tolerance at the same conditions.

  • One of the main processes of tenderizing beef in Joseon Dynasty was chemical methods involving Apricot seeds, manchu cherry twig and leaves, bamboo skins, mulberry tree bark, mangsa (硭砂), salmiacum (磠砂), alcohol, fermented malt, and original honey. This study analyzed and compared the effect of broussonetia papyrifera, fermented malt, cherry trees, and mulberry tree bark from old cookbooks. Tenderizing beef with cherry trees was most effective in the experiment on shearing force, TPA, and electrophoresis of beef. According to sensory evaluation and electrophoresis test results, tenderized beef with mulberry tree bark was slightly more preferred over the method using cherry trees. However, in accordance with the above mentioned experiment, quantitative descriptive analysis showed that the most common tenderizing material was derived from morus alba powder.

  • Mulberry leaves containing 1-deoxynojirimycin (DNJ) have been recognized as a potentially important source for prevent or treat hyperglycemia. However, DNJ content of natural mulberry leaf are as low as 0.1%. Thus, the most effective method for increasing ${\alpha}$-glucosidase inhibitory activity with the DNJ high-production is needed. In this study, we investigated the influence of ${\alpha}$-glucosidase inhibitory activity according to different pH values (6-9) and inoculation amounts (0.1-0.5%) when Bacillus subtilis cultured on mulberry leaf powder media. We confirmed that ${\alpha}$-glucosidase inhibitory activity was difference according to culture conditions of different pH values, inoculation amounts, and fermentation times. The results of mulberry leaf fermentation according to pH values and inoculation amounts were shown that the optimal conditions for ${\alpha}$-glucosidase inhibitory activity were defined as pH 7 and 9, inoculation amount 0.4%, and incubation until 2 to 4 days. These results can be provided a basic data for the optimal culture conditions increasing ${\alpha}$-glucosidase inhibitory activity from mulberry leaf fermentation.

  • It has been known that the mulberry leaf is effective in many diseases. Nowadays, the pharmacological effects on diabetes mellitus of mulberry leaves have been confirmed and they are used for many aspects. And Mulberry leaves are also hewn to be effective in the prevention of diabetics, because of their rich amino acids and fibers. From the results of sensory evaluation, the addition of up to $0.5\%$ MLP(mulberry leaf patty), to the chicken patties induced no significant differences in texture, appearance, and color until $0.5\%$ adding of MLP. However, chicken patties with added $0\%$, and $0.25\%$ added of MLP were shown have the highest acceptability, so these levels were thought to be the proper addition amounts of MLP to the chicken patty. Brightness(L) of these patties was the highest in the $0\%$ group as (55.63) and decreased with increasing adding amount of MLP level. Redness(a) was decreased with increasing adding amount of MLP and appeared as ueenish. Yellowness(b) was the lowest in the $0\%$ MLP addition group as (13.31) and increased with increasing MLP level. Hardness was the highest in the chicken patty with $0.25\%$ added MLP, and the lowest value in the chicken patty with $0.5\%$ added MLP. Cohesiveness was the highest in $0\%$ added MLP added chicken patty and springiness was the highest in $0.5\%$ added MLP added chicken patty. But not significantly. Also Brittleness was similar among the various chicken patties with no significantly difference. As for the composition of fatty acids in the chicken patties with added MLP, saturated fatty acids were decreased and unsaturated fatty acids were increased with increasing MLP Especially, the contents of essential fatty acids showed a largely increasing tendency in the chicken patties with added MLP Linoleic acid, linolenic acid, and arachidonic acid were increased to $9.38mg\%,\;0.65mg\%\;and\;1.28mg\%$, respectively in chicken patty with $1.0\%$ added MLP.

  • 상수에 있어서 각종 재배조건을 달리했을 경우에 있어서 동화량의 차를 알기 위해 punch method를 건물량 증가로서 순동화량을 측정하였다. (1) 착엽부위별 건물양은 식아거리와 관계없이 수고 150cm 부위가 가장 많았고 200cm 부위, 100cm부위, 50cm부위 순으로 적었다. (2) 착엽부위에 다른 동화량의 일변화는 수고 150∼200cm 부위는 오전에 동화량이 많았고 50∼100cm 부위는 오후가 많았다. (3) 상전의 위치에 따른 건물량은 남쪽 외측이 가장 많았고 그 다음으로는 동쪽 외측이 많았으며 그 외는 큰 차가 없이 같은 경향이었다. (4) 상전의 위치별 동화량의 일변화는 동쪽은 오전 7시∼10시까지가 많은데 비해 남쪽은 오전 10시∼오후 1시까지가 많았다. (5) 상품종별 건물량을 비교한 결과를 보면 수원상 4호가 가장 많았고 시평, 개량서반, 노상의 순으로 적으며 1일간의 동화생산량도 수원상 4호가 가장 많고 개량서반, 시평, 노상의 순으로 적어졌다. (6) 벌채정도별 건물량증가와 1일간순동화량은 다같이 벌채정도가 강한 1/2벌채구가 가장 많았고 1/3벌채구, 무벌채구 순으로 적었다.

  • Artificial diet (AD) has shown with different advantages over mulberry leaves (ML). Various types of such feed for silkworm have been developed and proposed. The aims of this study were possibility rearing whole instar of silkworm on AD and to find some economic formulation for rearing silkworm, compare to that ML. Eleven ADs (D$_1$ to D$_{11}$) were prepared with different percentage of mulberry leaf powder, and other ingredients such as soybean meal, cellulose, potato starch, agar, wheat flour, rice bran, etc. Five formulated diets (D$_1$ D$_2$, D$_{5}$, D$_{10}$ and D$_{11}$) appeared to have similar response to that ML (D$_{m}$). There were no significant differences for duration period between ADs, all of which recorded with higher duration than mulberry leaves. Compared to other died used in the present study D$_1$ and D$_{10}$ showed better growth development and survival rate. Larvae fed D$_1$, D$_2$, D$_{5}$, D$_{10}$ and D$_{11}$ grew faster and produced heavier and more useful cocoons.coons.coons.coons.

  • 본 연구에서 선발된 17종의 천연물을 Sprague-Dawleyra rat에 급여한 결과, 체중증가, 에너지 소비, fat pads 중량, 간의 triglyceride함량, atherogenic index 그리고 혈중 글루코오스의 함량 등이 감소하는 경향을 나타내었다. 특히 동아를 구강으로 섭취시킨 결과, 체중증가, 에너지 소비, fat pads 중량, 그리고 혈중 글루코오스의 함량 등이 감소하였으나, 간의 triglyceride 함량은 오디와 송엽의 열수 추출물보다 적게 감소하였다. 동아, 오디, 그리고 송엽을 혼합하여 사용한 결과, 각각의 원효를 사용할 경우보다 비만이 개선되는 것으로 나타났다.
