노루궁뎅이균사로 발효한 율무 열수추출물의 항산화, NO 생성저해, tyrosinase 합성 억제, melanin 생성 저해 및 유용성분 분석을 수행하였다. 노루궁뎅이균사발효율무 열수추출물의 ergosterol 함량은 740.2 mg%으로 나타났으며, 원료로 사용한 율무 열수추출물에서는 검출되지 않았다. 노루궁뎅이균사발효율무 열수추출물의 β-glucan 함 량은 245.3 ± 5.1 mg%으로 나타났다. 노루궁뎅이균사발 효율무 열수추출물은 100%, 104.1%, 107.2%, 105.3%, 102.1%, 101.3%, 100.4%의 세포생존율이 측정되어, 율무 열수추출물보다 노루궁뎅이균사발효율무 열수추출물의 세포생존율이 더 높게 나타났다. B16F10 cell 500 ug/mL 농도로 처리했을 때, 노루궁뎅이균사발효율무 열수추출물 은 8.9 μM의 NO 생성율을 보여, 율무 추출물(10.6 uM) 의 NO생성율 보다 낮은 NO 생성율을 나타내었다. 10, 30, 50, 100, 200, 300 및 500 mg/mL 모든 농도에서 율무 열수추출물보다 노루궁뎅이균사발효율무 열수추출물이 유의적으로 tyrosinase 및 melanin 생성을 억제함을 확인 할 수 있었다. 노루궁뎅이균사발효에 따른 DPPH radical 및 ABTS radical 소거활성 측정결과 노루궁뎅이 균사발효 율무열수추출물이 율무 열수추출물보다 항산화 효과가 높음을 확인하였다. 따라서 추가적인 연구를 통해 노루궁뎅이균사발효 율무열수추출물은 기능성식품 원료와 식품 첨가물, 화장품 산업에 이용될 수 있을 것으로 생각된다.

This study investigated the sensory characteristics of adlay tea favorably consumed by Korean consumers and analyzed the drivers behind for liking or disliking adlay tea. Six adlay tea products showing the highest market share in South Korea were selected. Sensory properties of the six products were analyzed using generic descriptive analysis. Among these, four products were further selected for consumer taste acceptance test. Sensory lexicons of adlay tea were developed by trained panelists, and the sensory characteristics of each adlay tea product were measured based on the perceived intensities of these attributes elicited from the samples. In the consumer taste acceptance test, frequent tea and coffee drinkers participated. Consumers rated the acceptance of each tea product on a 9-point hedonic scale and evaluated the reasons for liking or disliking each product based on the check-all-that-apply method. Analysis of Variance, principal component analysis, frequency analysis, and correspondence analysis were utilized for statistical analysis. Twenty sensory attributes were developed in order to characterize the six adlay tea products. The results of the descriptive analysis showed that attributes such as viscosity, black soybean flavor, goso flavor, peanut flavor, seaweed flavor, green, and presence of chunks were key factors differentiating the adlay tea products. In the consumer taste test, roasted flavor, goso flavor, peanut flavor, and presence of chunks were positive drivers for liking the adlay tea products, whereas seaweed and green flavors were negative attributes that drove consumers away.

남주지방에 알맞는 청예 사초용 율무의 질소시비수준을 구명코자 1989년 4월부터 1990년 8월까지 순천대학교 부속 동물사육장 내 사료작물포장에서 시험을 수행하였던 바 그 결과를 요약하면 다음과 같다. 1. 질소의 시용은 13.5kg/10a까지 직선적인 증수를 나타냈으나 18kg/a의 다비구는 시비방법에서 2구의 추비 결과로 도복과 과번무가 나타나 오히려 감수하였다. 2. 적정 시비수준은 NP2O5-K2O=13.5-6.6 kg/10a로 사료되

남부지방에 적합한 청예사초용 율무의 파종적기를 구명코자 다수성으로 인정된 승주 재래종을 공시하여 시험했던 바 그 결과를 요약하면 다음과 같다. 1. 초장, 경태, 엽수 등의 수량 구성형질은 4월 15일에 파종한 구가 가장 우수하였다. 2. 생초수량과 건물수량은 역시 4월 15일에 파종한 구가 증수되었다. 3. 조단백질 함량은 파종기가 늦어질수록 높았고 NDF, ADF 등의 조섬유 함량은 파종기가 늦어질수록 저하되었다.

Background : In previous studies, adlay seeds showed a prevalence of diversified fungal flora with the predominant fungal genera being Fusarium (45.6%) and In vitro test showed that fungal toxins like Fumonisin and Zearalenone were produced by Fusarium fujikuroi, F. asiaticum and F. graminearum. Because of this we performed experiments to selecting disinfective chemicals for controlling the Fusarium contamination in the adlay seed. Methods and Results : We carried out the chemical efficacy test such as seed disinfectants selection test appling before planting and pesticides selection test using in the earing season. In the present study, eleven different commercially available seed disinfectant were applied to the adlay seeds. Among 11 seed disinfectants, Hexaconazole+Prochloraz emulsifiable concentrate (EC) and Prochloraz emulsifiable concentrate (EC) had control value of 80% or above against Fusarium species tested. In the pesticides selection test, seven different commercially available pesticides for Fusarium blight (Scab) control were applied and we observed that Metconazole suspension concentrate(SC) strongly inhibited the mycelial growth of 10 Fusarium species all. Conclusion : From the above results, we selected Hexaconazole+Prochloraz EC and Prochloraz EC as a seed disinfectants and Metconazole SC as a pesticide using in the earing season for Scab control.

Background : The aim of the present study was to identify an effective physicochemical control method to reduce Fusarium species infestation in adlay (Coix lacryma-jobi L.) before and after harvesting. Methods and Results : We observed that prochloraz emusifiable concentrate and hexaconazol prochloraz emusifiable concentrate strongly inhibited the mycelial growth of 10 Fusarium species. Strong growth inhibitions and cell lysis were observed following treatment with 4% NaOCl solution. The total number of fungi detected were lower follwing treatment with thiophanatemethyl triflumizole wettable powder (1.1 × 104 CFU/g), hexaconazol prochloraz emulsifiable concentrate (1.2 × 104 CFU/g), carboxin thiram dustable powder (1.6 × 104 CFU/g) and prochloraz emulsifiable concentrate (1.7 × 104 CFU/g) than in the non-treated control (7.7 × 104 CFU/g). The reduction of Fusarium fungi varies with the concentration and soaking time of NaOCl solution. Fungal detection was not observed after soaking in NaOCl solution for 24 h and harmful effects were not observed for plant growth by NaOCl after soacking for 6 - 12 h. Conclusion : Soaking seed for 6 - 12 h in 4% NaOCl could be an effective method of disinfectant treatment for the control of Fusarium fungi in adlay seeds.

For the development of a new antidementia functional food or alternative drug using agricultural products,Job's tears (Coix lachrymajobi L.), which shows high acetylcholinesterase (AChE) inhibitory activity (55.1%) was selectedand the extraction conditions of AChE inhibitor were optimized. AChE inhibitor of Job's tears was maximally extractedwhen it was treated with 60% methanol at 40℃ for 6h. The AChE inhibitor of the methanol extracts was partially purifiedby systematic solvent extraction, thin layer chromatography, silica gel chromatography and reverse-phase HPLC and thepartial purified AChE inhibitor with inhibitory activity (IC50) of 0.608㎍ was obtained. The partial purified AChE inhibitorwas soluble in methanol and hexane, and insoluble in water. Its maximum absorption spectra was 230㎚ and also it was sta-ble in the range of 30℃ and 70℃ and pH 4.0-8.0 for 1h.
