경북 상주지역에서 가장 많이 재배되고 있는 둥시와 청도지역의 대표적인 반시를 공시하여 동결감의 제조 및 해동중에 일어나는 품질변화를 구명하기 위하여 연구한 결과, 동결감 과육의 온도변화는 -4$0^{\circ}C$까지 도달하는 시간이 상주둥시보다 청도반시가 10~20분 더 소요되었고 감은 -2$^{\circ}C$~3$^{\circ}C$에서 동결되었다. 동결저장중의 파열과 발생은 상주둥시가 24.5%, 청도반시가 15.5%로 청도반시가 상주둥시보다 상대적으로 적게 파열되어 동결감 제조시 청도반시가 더 유리하였다. 해동온도별 경도변화는 상주둥시 5$^{\circ}C$에서 150분, 청도반시 120분이 소요되었고 1$0^{\circ}C$, 2$0^{\circ}C$, 3$0^{\circ}C$로 해동할 경우 현저히 해동시간을 단축할 수 있었다. 해동온도별 해동전후의 색도의 변화는 L값은 해동전과 비교하여 약간 감소하였으나, a, b값은 급격히 어두운 갈색으로 변하는 경향을 보였다. 동결감 제조시기별 당도의 변화는 수확, 연시, 동결, 해동 단계별로 두 품종 공히 별다른 변화를 보이지 않았다. 완전해동시까지의 도달시간은 상온에서(10.9~14.8$^{\circ}C$)상주둥시가 4시간 30분, 청도반시는 4시간 20분 소요되었다.

This study was conducted in order to promote the utilization of Hovenia dulcis Thunb as food. The physicochemical properties and sensory characteristics of the extracts from the leaf, fruit, stalk and stem were examined. The extract of stem was the brightest in L value (p<0.05), but the lowest in b value (p<0.01). By the sensory evaluation, the external appearance was the best in the extract of stem. The extract of leaf was the darkest in color and that of stem the lightest. The bitter and astringent taste was stronger from the leaf compared with other parts. The extract of fruits stalk of Korean Hovenia dulcis was preferred in most of attributes. The total sugar content was the highest from the fruits stalk. Among free amino acids, aspartic acid, glutamic acid and alanine were rich in order. Potassium contents were the highest among minerals from the fruits stalk, leaf and stem. Ca and Mg followed the next. The results were the same both in Korean and in Chinese tree. Among organic acids, malic acid was the most in the fruits stalk, leaf and stem. It was followed by citric acid. In the test of free sugar, glucose was the most and followed by sucrose and fructose in the fruits stalk. Fructose was contained the most in leaf and stem.

감관총채벌레가 2000년에 처음으로 보고된 이후 남부지방에서 계속 분포가 확산되고 있어서 설문조사를 통해 그 분포확산 정도를 조사하였다. 조사결과 감관총채벌레는 1995년에 전남 장성군에서 최초로 발생하였으며, 현재는 울산광역시와 충북, 전북, 전남, 경북, 경남, 제주 등 6개 도의 26개 시군에서 발생하고 있고, 경남의 창원과 밀양 지역이 피해가 가장 심하였다. 1995년부터 2003년 4월까지 누적된 발생면적은 총 151 ha이었으며, 단감 뿐만 아니라 떫은감에도 발생하였다.

Changes in antioxidative substance levels in eleven different cultivars of persimmon leaves during growth were investigated. In general, the contents of soluble phenols, L-ascorbic acid and flavonoids in astringent persimmon leaves(APL) were higher than those of nonastringent persimmon leaves(NAPL). The soluble phenol contents in APL and NAPL showed a tendency to decrease throughout leaf growth. L-ascorbic acid content in APL decreased rapidly during growth, whereas its content in NAPL reached its highest value at the late of July, and then decreased rapidly. Major flavonoids in APL and NAPL were quercetin and Kaempferol which were present in conjugate forms. Before acid hydrolysis, the contents of kaempferol and quercetin in APL and NAPL remained at a relatively constant level until the late of July, and then decreased slightly. After acid hydrolysis, kaempferol contents in APL and NAPL varied significantly by cultivar and growth stage, while quercetin contents decreased slowly until the late of July, and then increased drastically, reached a maximum at the early of August, afterward continuously decreased. These results suggest that APL harvested at the early of June may be useful as potential sources of natural antioxidants.

Cinnamomi Cortex (Lauraceae), the dried bark of Cinnamomum cassia BLUME, has been used as traditional Chinese medicine for its stomachic, astringent, carminative, antispasmodic, antibacterial, antifungal properties. Four compounds were isolated from the MeOH extract of Cinnamomi Cortex, and their structures were identified as trans-cinnamic acid (1), ${\beta}-sitosterol$ (2), bis(2-methylheptyl)phthalate (3), coumarin (4) by comparison of their physical and spectral data with those reported in the literature. These compounds were tested melanogenesis inhibitory effect on B-16 mouse melanoma cell lines. Among them, trans-cinnamic acid (1) showed the most potent inhibitory effect on melanogenesis with $IC_{50}$ value of $13{\mu}g/ml$. Arbutin, positive control, exhibited an $IC_{50}$ value of $29{\mu}g/ml$.

It has long teen known in herbal medicine that the mugwort not only exerts a strong hemostatic and parasiticidal actions but also has therapeutic effects for stomachache and diarrhea. In recent pharmaceutical botany the mugwort is known to have antipyretic and astringent actions also. Among the major principles which have been found in the leaves and stems of mugwort are inulin, alkaloids, vitamines, and esestial oil. It is well known that santonin, one of the well known parasiticides, is one of the glucosides extracted from the limited species of mugwort. The present study was undertaken to investigate effects of mugwort(Artemisia asiatica Nakai) on the motility of isolated rabbit duodenum. The results obtained are as follows: At does of 0.2%, 0.5% and 1. 0% AAJ(Artemisia asiatica juice) markedly enhanced contractility of isolated duodenum and tonus of the intestine was also augmented with doses of 0.5% and 1.0%. The augmentative effect of AAJ on intestinal motility was not affected by pretreatment with epinephrine and avil while it was completely abolished by atropine. Therefore it is strongly suggested that augmentative action of AAJ on duodenal motility was exerted solely through muscarinic cholinergic receptors.

Quality characteristics of sausage with added pine needle powder (0%, 0.5%, 1.0%, 1.5%, 2.0%, and 2.5%) as an ingredient. The basic ingredients of sausage consisted of pork meat 60%, olive oil 20%, and ice water 20%. Sensory properties of sausage were analyzed by a sensory test, and the texture and color characteristics were measured using a texturometer and color meter, respectively. In the results of the sensory test, taste, texture, and overall preference were highest in the sample with added 1.5% pine needle powder. The sausage with added 1.5% pine needle powder was moderate in color intensity, pine needle flavor, and astringent taste. Hardness and gumminess of sausage were higher in 1.0% and 1.5% pine needle powder. However, springness and chewiness of sausage showed no significant differences. In terms of color intensity of sausage, L-value and a-value were lower and b-value was higher, depending on the pine needle powder amount. Development of off-flavor of sausage during storage was greater in 0% and 1.5% added sausages than in 2.0% sausage with increasing storage time. As a conclusion, sausages with added 1.5% and 2.0% pine needle powder were the most suitable for making functional sausage with added pine needle powder.

Phenolic compounds play a major role in the interaction of plants with their environment. They are thought to have been a feature of higher plants since early colonization of the land. Phenolics are crucial for many important aspects of plant life. They can play structural roles in different supporting or protective tissues, for example in cell walls, they can be involved in defence strategies, and signalling properties particularly in the interactions between plants and their environment. In brown algae, phenolic compounds are contained within membrane bound vesicles known as physodes, and their roles in algae are thought to be similar to those of higher plant phenolics. They can be stained using various histochemical stains, however, none of these stains are phenolic specific so care must be taken during interpretation of such results. Many, but not all phenolics are also autofluorescent under UV or violet light. Physodes are involved in cell wall construction, both in primary and secondary walls in brown algae. They bind together with other wall components to make a tough wall. They have also been found to play a role at fertilization, in blocking polyspermy in some species. Sperm are very quickly rendered immobile after phenolic release from newly fertilized zygotes seconds after fertilization. Phenolic compounds are thought to be important herbivore deterrents in some species due to their astringent nature. Phenolic compounds also offer effective UV protection in the early life stages and also the adults of many algal species. In the future, this factor may also make them an important player in the pharmaceutical and skincare industries.
