Lipid-extracted microalgae (LEM, Tetraselmis KCTC 12236BP), a solid waste by-product obtained from algal biodiesel production, is typically considered rich source of antioxidant compounds, including phenolic compounds. The purpose this study was to apply statistically-based methodology enhance the extraction total compounds (TPCs) and activity (AA) LEM verify production epigallocatechin gallate (EGCG), bioactive material, under optimum conditions. optimal extractions TPC AA were explored by...
Response surface methodology was employed to optimize the ultrasound-assisted extraction (UAE) conditions for simultaneous optimization of dependent variables, including DPPH radical scavenging activity (RSA), tyrosinase inhibition (TAI), and collagenase (CAI) peanut shell extracts. The effects main variables time (5.0~55.0 min, X1), temperature (26.0~94.0 °C, X2), ethanol concentration (0.0%~99.5%, X3) were optimized. Based on experimental values from each condition, quadratic regression...
Aquaculture drugs have used to prevent disease in aquaculture field for many years. In spite of advantages, overdose and abuse may cause environmental pollutions antibiotic resistances. Many countries try protect the environment, biospecies food safety. Recently, Korea enact laws ordinances such as Aquatic Animal Disease Control Act. The purpose this act contribute stable production control system aquatic diseases. Maximum residue limits (MRLs) been established by Ministry Food Drug Safety...
The aim of this study was to investigate the effect Canavalia gladiata extract (CGE) on regulation AMP-activated protein kinase (AMPK) in 3T3-L1 preadipocytes and evaluate adipogenesis lipogenesis mechanisms. In preadipocytes, lipid accumulation differentiation were suppressed by 1.1, 1.3, 1.4 times under CGE treatment at 0.25, 0.5, 1.0 mg/mL, respectively. expression main genes involved inhibition evaluated mRNA level via a transcription-polymerase chain reaction. mg/mL increased...
Biotransformation of daidzein was performed by using Bacillus amyloliquefaciens KCTC 13588, Lactococcus lactis subsp. 3769, Leuconostoc citreum 13186, Kluyveromyces var. 17704, Pediococcus pentosaceus 3116, and Lactobacillus sakei 13416 cells as a biocatalyst. Four derivatives such daidzein-7-O-phosphate, daidzein-7-O-β-D-glucoside, daidzein-7-O-β-(6′′-O-succinyl)-D-glucoside, 4′-Ethoxy-daidzein-7-O-β-(6′′-O-succinyl)-D-glucoside were isolated from the biotransformation reaction mixture. The...
본 연구에서는 초음파를 이용하여 농업 부산물인 피땅콩 겉껍질의 추출 조건을 최적화하고 추출물의 항산화능과 항비만 기능성을 측정하였다. 실험설계는 CCD를 이용하였고 독립 변수인 시간, 온도, 에탄올 농도에 따라 TPC, TFC와 RSA를 종속 변수로 설정하여 이들의 값을 최대로 하는 공통 예측하였다. 각각의 모델식의 R²값은 0.85 이상으로 적합하였으며, 조건으로 온도와 농도가 TPC 및 TFC에 유의적인 영향을 주는 것을 알 수 있었다. 반면 RSA는 많이 받는데, 높을수록 RSA가 높아지다가 최고점을 보인 후 다시 감소하는 경향을 나타내었다. 최적 조건인 시간 35.8분, 온도 82.7°C와 96.0%에서 제조한 RSA의 실측치는 예측치와 유사한 나타내어 회귀 방정식이 신뢰할 있음을 확인하였다. 기능성 평가를 위한 GIA와 LIA 실험 결과는 각각 86.4%와 78.5%로 열수 추출물보다 높게 나타나 초음파 추출에 의한 생리활성 물질 추출이 효과적임을 이로써 겉껍질로부터...
Statistically-based optimization using response surface methodology was performed to derive optimal extraction conditions for the of bioactive compounds with antioxidant activity, skin whitening, and anti-wrinkle effects from Sargassum horneri, marine waste, ultrasound-assisted (UAE). The main UAE process variables, time (5.3~18.7 min, X₁), temperature (22.4~79.6°C, X₂), ethanol concentration (0~99.5% v/v, X₃), were selected through preliminary experiments optimized central composite design...
양식어류 질병 세균에 대한 31종의 천연물을 <TEX>$70\%$</TEX> ethanol로 추출하여 항균효과를 조사하였다. 그 중에서 망태버섯 ethanol 추출물이 비교적 높은 활성을 나타내었으며, 망태버섯을 극성이 낮은 dichlorornethane, ethyl acetate, n-buthanol, water의 순서로 분획하여 본 결과 acetate 추출물에서 모든 균주에대한 clear zone을 형성하여 항균효과가 보였다. 또한, 망태버섯로부터의 추출물을 Si-chromatography를 이용하여 fraction별 7개로 조사한 Fraction 2 (Hx :EtAOc, 3: 1)에서는 L. anguillarum에 대해 가장 뛰어났으며, 5 (DCM:MeOH, 5: 1)에서 5. iniae가 높았다. 세 균주에 대해서 공통적으로 항균활성이 것은 5로 나타났다.

This comprehensive review examines the relationship between diet and cognitive function across life stages, from fetal development through advanced age. We examine how nutritional needs evolve different periods, supporting brain capabilities. The analyzes impact of key nutrients on function, including macronutrients (carbohydrates, proteins, fats) micronutrients (vitamins B6, B12, folate, A, C, E, D, minerals). explore phytonutrients, particularly polyphenols flavonoids, which demonstrate...
Commiphora molmol myrrh resin extracts, which have different physical properties such as polarity and dielectric constant, were prepared by immersion in extraction solvents (hot water, DMSO, hexane, ethanol, methanol). Methanolic extracts showed broad antibacterial activity against isolated airborne bacteria. Furanoeudesma-1,3-diene curzerene, the main terpenoids methanolic extract, analyzed using GC-MS, found to antiviral (81.2% viral RNA inhibition) H1N1 influenza virus. Biochars (wood...
