Medium Light and Medium Roast Paper-Filtered Coffee Increased Antioxidant Capacity in Healthy Volunteers: Results of a Randomized Trial 总被引:1,自引:1,他引:0
TA Corrêa MP Monteiro TM Mendes DM Oliveira MM Rogero CI Benites CG Vinagre BM Mioto D Tarasoutchi VL Tuda LA César EA Torres 《Plant foods for human nutrition (Dordrecht, Netherlands)》2012,67(3):277-282
We compared the effects of medium light roast (MLR) and medium roast (MR) paper-filtered coffee on antioxidant capacity and lipid peroxidation in healthy volunteers. In a randomized crossover study, 20 volunteers consumed 482?±?61?ml/day of MLR or MR for four weeks. Plasma total antioxidant status (TAS), oxygen radical absorbance capacity (ORAC), oxidized LDL and 8-epi-prostaglandin F2α, erythrocyte superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT) activity were measured at baseline and after the interventions. MLR had higher chlorogenic acids-(CGA; 334?mg/150?mL) and less caffeine (231?mg/150?ml) than MR had (210 and 244?mg/150?ml, respectively). MLR also had fewer Maillard reaction products (MRP) than MR had. Compared with baseline, subjects had an increase of 21 and 26?% in TAS, 13 and 13?% in CAT, 52 and 75?% in SOD, and 62 and 49?% in GPx after MLR and MR consumption (P?0.001), respectively. ORAC increased after MLR (P?=?0.004). No significant alteration in lipid peroxidation biomarkers was observed. Both coffees had antioxidant effects. Although MLR contained more CGA, there were similar antioxidant effects between the treatments. MRP may have contributed as an antioxidant. These effects may be important in protecting biological systems and reducing the risk of diseases related to oxidative stress. 相似文献

盆栽芍药泥炭替代型有机栽培基质研究 总被引:4,自引:0,他引:4
以发酵过的菇渣、玉米芯颗粒部分或全部替代泥炭,进行芍药品种大富贵的盆栽试验;以传统泥炭为主的栽培基质配方为对照,设置7种代用型栽培基质配方(其中含泥炭的3种,不含泥炭的4种),分别测定其基本理化性质及营养元素含量;比较各栽培基质对盆栽芍药的地上、地下生物量的影响,从而筛选出适宜芍药盆栽生产的泥炭替代型有机栽培基质配方:40%泥炭+20%菇渣+20%珍珠岩+20%陶粒(体积比)。 相似文献

为了优化芸薹属远缘杂交试管苗的快繁培养基,探讨基因型、培养时间等因素对试管苗分化率的影响,实验对甘蓝型油菜与甘蓝以及白菜型油菜与甘蓝两种远缘杂交方式的试管苗,在10种添加了不同浓度的6-BA和NAA的培养基上进行快繁培养。采用SAS软件对培养后第20d和第30d的分化率进行分析处理,结果如下:(1)白菜型油菜与甘蓝5个杂交组合间,以及白菜型油菜与甘蓝、甘蓝型油菜与甘蓝两种杂交类型间的试管苗分化率无显著差异;除甘蓝型油菜与甘蓝杂交的试管苗在培养第30d时的分化率无显著差异外,其它情况下培养基间的诱导分化率差异均达到显著或极显著水平;(2)添加3.0 mg&;#8226;L-1 6-BA(6-苄基嘌呤)和0.2 mg&;#8226;L-1 NAA(萘乙酸)的MS培养基对试管苗的诱导分化效率显著或极显著高于其它快繁培养基;(3)不同培养基培养的试管苗在培养20d和30d时的分化率呈高度正相关,但前20d的日平均分化率显著高于20~30d的日平均分化率。 相似文献
