  • Prunus mume, also known as maesil, is a popular fruit consumed in East Asia (Korea, Japan, and China). It contains high amounts of organic acids, minerals, and polyphenols and has been used as a medication for fever, vomiting, and detoxification. In this study, the anti-proliferative and apoptotic effects of solvent fractions from maesil were evaluated using sulforhodamine B (SRB) assays, morphological evaluations, Hoechst 33258 staining, and western blotting. Addition of the maesil methanol fraction (MMF) and the maesil butanol fraction (MBF) significantly and dose-dependently decreased the cell viability of HT-29 human colon cancer cells. Colony-forming assays confirmed that the MMF and MBF treatments decreased colony numbers when compared with untreated control cells. Treatment of HT-29 cells with MMF and MBF caused a distortion of the cell morphology to a shrunken cell mass. Treatment with MMF and MBF also dose-dependently increased nuclear condensation and the formation of apoptotic bodies in HT-29 cells. Treatment with MMF and MBF significantly and dosedependently increased the expression of Bax (a pro-apoptotic protein), caspase-3, and poly ADP-ribose polymerase (PARP) and decreased the expression of Bcl-2 (an anti-apoptotic protein). MMF significantly and dose-dependently inhibited cell proliferation induced by bisphenol A, an environmental hormone. Therefore, MMF may have potential use as a functional food and as a possible therapeutic agent for the prevention of colon cancer.

  • Inactivation of Salmonella Typhimurium and Listeria monocytogenenes in mandarin orange, Prunus mume (maesil), and kiwi juices was evaluated. A three-strain mixture of S. Typhimurium or L. monocytogenes was inoculated (7 log CFU/ml) into a commercial mandarin orange juice and maesil juice, and home-maid kiwi extract. The inactivation effect of Maesil juice was estimated by the addition into the other two fruit juices. All fruit juices had acidic pH, ranging from 2.8 to 3.5 and it was not variable during all experimental period, being at $4^{\circ}C$ for 14 days, The present study demonstrated that Maesil juice inactivated throughly L. monocytogenes within 7 days, while kiwi extract and mandarin orange juice archived 3.0-log inactivation and 1.0-log inactivation, respectively, until 14 days of storage. S. Typhimurium was completely reduced by Maesil juice and kiwi extract within 14 days, but mandarin orange juice showed only 1.4-log inactivation. The inactivation of L. monocytogenes and S. Typhimurium was increased by adding 10% maesil juice to both mandarin orange juice and kiwi extract.

  • In this study we assessed the effects of gamma irradiation ($0.5{\sim}3\;kGy$) on the microbial and physico-chemical characteristics of maesil (Prunus mume) stored for 9 days at $20^{\circ}C$. Total aerobic bacteria, yeasts and molds were significantly decreased with increases in the irradiation dosage. In terms of the Hunter's color value, irradiated samples evidenced a higher b-value, but a lower a-value than the non-irradiated samples. Hardness was reduced with increment in the irradiation dose level. The contents of total sugar, hydrogen donating activity and organic acids were not affected by irradiation. The reducing sugar contents of the irradiated samples were superior to those of the non-irradiated samples. Vitamin C contents were reduced with the progression of storage periods and increases in the dosage level. These results demonstrated that gamma irradiation of 0.5 to 3 kGy affected the microbiological safety of maesil, but did not affect the physico-chemical characteristics(total sugar, hydrogen donating activity and organic acid) but the Hunter's color value, hardness, and vitamin C contents of the maesil deteriorated with gamma irradiation.

  • 매실나무겨우살이 막걸리의 생리적 효능을 검정하여 의약 화장품의 소재화 가능성을 검토할 목적으로 발효기간과 겨우살이 함량에 따른 총 폴리페놀, 플라보노이드 함량, DPPH free radical 소거능을 측정하였고, tyrosinase 저해활성은 5분 간격으로 65분간 측정하였다. 막걸리는 백미와 기장을 7:3의 비율로, 겨우살이의 함량을 0%, 5%, 10%로 달리하여 10일 간격으로 최대 30일까지 Shaking incubator($30{\sim}35^{\circ}C$, 100 rpm)에서 발효하였고, 발효가 끝난 막걸리는 80 mesh 망으로 여과하였다. 총 폴리페놀 함량은 10일에 최대치를 나타내었고, 0%는 $633.53{\mu}g/ml$, 5%는 $759.67{\mu}g/ml$, 10%는 $752.2{\mu}g/ml$을 나타내었다. 기간이 경과함에 따라 감소하는 경향이었으며 30일에 0%는 $507.57{\mu}g/ml$, 5%는 $570.13{\mu}g/ml$, 10%는 $551{\mu}g/ml$를 함유하고 있는 것으로 나타났다. 총 플라보노이드 함량 또한 10일에 최대치를 나타내었고, 0%는 $16.18{\mu}g/ml$, 5%는 $63.87{\mu}g/ml$, 10%는 $62.99{\mu}g/ml$였고, 기간이 경과함에 따라 감소하는 경향성을 나타내어 30일에 0%는 $0.59{\mu}g/ml$, 5%는 $10.98{\mu}g/ml$, 10%는 $1.18{\mu}g/ml$를 함유하였다. DPPH free radical 소거능은 0%의 경우 10일에 72.34%로 최대치가 나타났고, 30일에 58.61%로 가장 낮은 소거능을 보여주어 기간이 경과함에 따라 감소하는 경향성을 보여주었다. 하지만, 겨우살이 첨가군인 5%(10일:91.13%, 20일:91.09%)와 10%(10일:91%, 20일:90.8%)는 비교적 차이가 없었고, 발효기간이 30일이 경과한 후 5%는 93.46%, 10%는 92.3%로 최대값을 보여주었다. Tyrosinase 저해활성은 DPPH free radical 소거능이 가장 좋은 30일 발효 막걸리를 측정하였다. 모든 겨우살이 첨가군에서 5분이 경과하였을 때, 0%는 82.68%, 5%는 69.29%, 10%는 79.53%의 저해활성을 나타내었으며, 시간에 유의적으로 저해활성이 감소하였다. 본 연구 결과에 따르면, 겨우살이 막걸리의 총 폴리페놀과 플라보노이드 함량은 기간이 경과함에 따라 감소함에도 불구하고, DPPH free radical 소거능은 증가함을 알 수 있었다. Tyrosinase 저해활성은 5% 첨가 막걸리에서 가장 낮았으며, 겨우살이를 첨가하지 않은 0%에서 가장 저해활성이 높고 오랜시간 유지되는 것을 확인할 수 있었다.

  • Picrate, enzyme-picrate and instrumental analysis methods using IC (Ion Chromatography) and HPLC (High Performance Liquid Chromatography) were compared for their effectiveness in determining cyanide in extracts of Maesil, which is classified as a harmful substance. First, the picrate method showed the shortest analysis time (about 5 hr). The color of picrate paper changed at 0.01 mg/$200\;mL\;CN^-$. However, it was difficult to detect cyanide from amygdalin of glucosides. Second, we performed a qualitative analysis for total cyanide (free cyanide and cyanide from amygdalin) by the enzyme-picrate method using $\beta$-glucosidase and a quantitative analysis by spectrophotometry. Finally, analysis of cyanide by IC and HPLC required the longest determining time (about 17 hr) as well as pretreatment for each free cyanide and amygdalin. These results suggest that enzyme-picrate is the most effective analysis method for the detection of cyanide in Maesil extracts.

  • Traditional food soybean curd was prepared using the fresh fruit juice of Schizandra chinensis RUPRECHT(Omija) and Prunus mume(maesil), and investigated the optimal preparative conditions(water addition ratio, heating time of mashed soybean and fresh fruit juice concentration), physical properties, sensory evaluation and shelf-life. Soybean curd coagulated with 0.9% Omija juice showed the highest yield at $85^{\circ}C$, 12.5 times water addition and 5 min heating. For soybean curd coagulated with 1.5% Maesil juice showed the highest yield at $85^{\circ}C$, 10 times water addition and 5 min heating. The physical properties (hardness, adhesiveness, chewiness and gumminess) of soybean curd coagulated with juices of Omija and Maesil showed lower values for hardness, adhesiveness, chewiness and gumminess. However sensory scores of both were evaluated higher than those of coagulated with $CaSO_4$. The shelf-life of soybean curd prepared from Omija and Masil juices and then soaked in 0.1% acetic acid was better than that of coagulated with $CaSO_4$ or soaked in distilled water.

  • This study examines features in using Japanese apricots that assume a leading place with a special symbolism among various species of trees adopted to traditional gardens from a landscaping view. Specific aspects of how Japanese apricots were adopted to traditional gardens are as follows. First, while Japanese apricots are used in modern landscape space, there traditionally were six types in use of Japanese apricots as Tammae(探梅) Jungmae(庭梅) Bunmae(盆梅) Byoungmae(甁梅) Chomae(造梅) and Mukmae(墨梅). Second, Japanese apricots planted in gardens[庭梅] were placed mainly in a front yard of Sarang-Chae(the men's part of a traditional house) took a central area because symbolism and ornamental values of Japanese apricots suited what classical scholars sought. Preferred planting sites at that time include south of the building, the yard of Sarang-Chae, space in front of windows and next to fences and waterside. Third, Japanese apricots in traditional gardens were planted in five ways; Dansik(單植) Daesik(對植) Gunsik(群植) Yeolsik(列植) Honsik(混植). Dansik was the most common way in planting Japanese apricots and Daesik intended to enhance orderedness and symbolism of space. Japanese apricots for appreciating in an open field took the form of Gunsik in general but Honsik was also used with species of special symbolism. This study offers an opportunity to grasp traditional planting methods of Japanese apricots based on understanding of cultural aspects of Japanese apricots by focusing on Japanese apricots, the representative traditional species of trees. Results of the study would help to recognize the need to newly understand Japanese apricots and be useful information to plant and use Japanese apricots in a traditional way.
