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.

It was pointed out by Katagiri and Nakahama that the useful retling bacteria acted selectively on vegetable fiber materials and also they proposed that this selectivity was based on the specificity of protopectinase of the bacteria, and that the two characters might have certain parallel relation with each other. The result of the further experiments carried out by the author with mulberry-tree bark also confirmed the selectivity of some kinds of retling bacteria, but found no remarkably different action on protopectin from mulberry-tree bark. Accordingly no parallel relation between the selectivity of the retling bacteria and the specificity of the protopectinase was identified.

This study explores the kinds and types of dyes used in the Joseon Dynasty. Some literature including "Sanga Yorok", "Gyuhap Chongseo", "Imwon Gyeonjeji" were reviewed for this purpose. The findings are as follows. The colors obtained from the dyes were divided into seven color series, such as red, yellow and orange, green, blue, purple, brown, gray and black. These are practical color categories differed from abstract five cardinal colors [五方色]. The diachronic dyes used during the Joseon Dynasty were safflower and Japanese alder bark for red, indigo leaves for blue, gromwell for purple, chestnut tree bark for brown. The representative dyes used in the late Joseon Dynasty were safflower and sappan wood for red, wild pear tree bark and Pentapetes phoenicea for yellow and orange, indigo leaves for blue, sappan wood and gromwell for purple, mulberry tree for brown, and Chinese ink for gray. Common dyes used both in Joseon and China were safflower and sappan wood for red, pagoda tree blossom for yellow, a combination of pagoda tree blossom (or Amur cork tree) and indigo leaves (or sediment) for green, indigo leavers or sediment for blue, sappan wood and hollyhock for purple, and a combination of indigo leaves and Galla Rhois for gray and black.

1983년 춘기 경북 중북부지방의 뽕밭에 원인불명의 발아불량현상이 발생하였던 바, 그 원인을 구명하기 위하여 대표적인 피해뽕밭을 선택 토양 및 식물체를 분석하였으며 피해지역의기온을 조사분석하여 다음과 같은 결론을 얻었다. 1. 피해상의 특징은 전혀 발아를 하지 않고 죽는 것과 발아도중 가지 선단부의 동아가 탈포기까지 피아가 갑자기 말라죽고 피부본부에 Necrosis 현상이 발생하며 심한 경우에는 가지의 기부에 Measles증상이 나타난다. 2. 유효토심은 피해뽕밭이 30cm이내, 건전뽕밭이 30-60cm이었다. 3. 토양 pH, 유기물 합량, 유효인산 및 치환성기 등은 피해뽕밭이나 건전뽕밭간에 차이가 없었다. 4. 토양내 유효붕소함량은 칠곡 및 상주 화서 뽕밭에서만 건전뽕밭이 피해뽕밭보다 유의하게 많았으며 선산 및 상주 낙동 뽕밭에서는 건전뽕밭이 피해뽕밭보다 약간 많았으나 유의차가 없었다. 5. 식물체의 붕소함량은 엽 피부 똑같이 건전뽕밭이 피해뽕밭보다 유의하게 많았다. 6. 발아불량 피해가 심하였던 뽕밭에 붕사를 첨가하여 사경재배한 뽕나무가 붕사나 붕소를 시용한 결과 토양 및 식물체내에 붕소함량이 유의하게 증가하였으며, 거의 100%에 가까운 회복률을 나타냈다. 7. 발아불량 뽕밭에 붕사를 시용한 뽕나무와 붕소를 첨가하여 사경재배한 뽕나무가 붕사나 붕소를 시용하지 않은 뽕나무보다 내동성이 강하게 나타났다. 8. 83년 하순의 이상고온이 예년보다 빨리 뽕나무의 수액을 상승시켰고 이로 인하여 발아유도가 빨랐기 때문에 4월 3일 조상최저기온이 -6.4$^{\circ}C$로 급강하하여 많은 뽕나무가 동해피해를 받았던 것 같다. 이상의 결과로 보아 83년 춘기 경북중북부지방의 뽕밭에 발생한 발아불량현상의 원인은 주인이 저온에 의한 동해라고 볼 수 있으며 지역적으로는 붕소결핍에 의한 발아불량현상도 적지 않았고 특히 붕소결핍이 동해피해를 가속화시켰다고 볼 수 있다.

The leaves (Mori Folium; MF), branches (Mori Ramulus; MR), and root bark (Mori Cortex Radicis; MCR) of the mulberry tree have been used as therapeutic herbs for centuries. Existing analytical methods were developed specifically for different parts of the tree and cannot be applied to samples containing a mixture of tree parts. Such method specialization is time-consuming and requires separate identification and quality control of each tree part. This report describes an HPLC method for the simultaneous quality control and discrimination of MF, MR, and MCR using four marker compounds: rutin, kuwanon G, oxyresveratrol, and morusin. An Optimapak $C_{18}$ column ($4.6{\times}250mm$, $5{\mu}m$) was used with a gradient elution of 0.1 % formic acid in water and acetonitrile. The flow rate was 1.0 mL/min and the detection wavelength was 270 nm. In quantitative analyses of the three parts, rutin (0.11 % w/w) was detected only in MF. The oxyresveratrol content (0.12 % w/w) was highest in MR. Kuwanon G (0.33 % w/w) and morusin (0.18 % w/w) were higher in MCR than in other parts. The HPLC method given herein can be used to simultaneously classify and quantify three herbal medicines from the mulberry tree.

The methanolic extract of the root-bark of Morus alba L.(Mulberry tree) has the potent antibacterial activity against Streptococcus mutans. Its active component was identified to be sanggenon C. The active component had stronger anti-bacterial activity than berberine, having minimum inhibitory concentration(MIC) of $25\;{\mu}g/ml$. Moreover, the inhibitory effect of this component on the cellular adherence of Streptococcus mutans to glass surfaces also was more remarkable than that of berberine in the presence of glucosyltransferase(GTase) and sucrose in vitro. These results indicate that sanggenon C may play an important role in inhibiting plaque formation and caries incidence.

Moraceae comprise a large family of sixty genera and neary 1,400 specieses, including important groups such as Artocarpus, Morus, and Ficus. In particular, Morus(mulberry) is a small genus of tree and shrubs found in temperate and subtropical regions of the Northern hemishere and has been widely cultivated in China and Korea, In addition, the root bark of mulberry tree have been used as an antiphlogic, diuretic, and expectorant in white medicine, and the crude drug is known as "Sangbaikpi" in Korea. Recently, some papers have been published reporting the hypotensive effect, antiviral effect, antifungal effect, inhibitory effect of cAMP-phosphodiesterase, and anticancer effect of this extract. Little is known about that Cortex mori could have been an antiallergic effect. The purpose of this study was the development of an antiallergic agent with an antiallergic effect from Cortex mori. For this, several in vivo and in vitro experimental models were used. Results are 1) Cortex mori inhibited the compound 48/80-induced degranu-lation, histamine release and calcium uptake of rat peritoneal mast cells, 2) compound 48/80-induced anaphylactic shock and cutaneous reaction were significantly inhibited by pretreatment of Cortex mori, and 3) Cortex mori inhibited the ovalbumin-induced late astmatic reaction. From the above results it is suggested that Cortex mori has some substances with an antiallergic activity. Our final purpose of this study is to develope the new drug with an antiallergic activity from Cortex mori
