Study on the characteristics of Syzygium cumini L. pigment

以海南蒲桃成熟果实为原料提取天然色素,并对其理化性质进行了分析研究。同时比较了D-072、D-401、D-301-G、D-101、D-110、DF01六种树脂对该色素的静态吸附情况及不同极性解吸剂对吸附色素的树脂洗脱的效果,从中选择吸附和解吸附效果最好的树脂以及适合的解吸剂。研究表明:该色素在酸性条件下对热、金属离子和常用食品添加剂均具有较好的稳定性,对光稳定性稍差;D-072大孔吸附树脂对海南蒲桃色素吸附效果最好,色素吸附率达90.7%;解吸剂用含0.2%三氟乙酸的50%酸化乙醇,色素可被充分洗脱下来。此研究结果为以海南蒲桃成熟果实为原料来生产食用色素提供了理论依据。The stability of pigment which was extracted from the fruit of Syzygium cumini was studied. In addition, absorbing and separating Syzygium cumini pingment with macroreticular resin was also studied. Static absorption capacity of six resins(D-072, D-401, D-301-G, D-101, D-110, DF01) for the pigment was compared. From these resins, the one with the best absorpting and desorpting effect was elected. The results showed that this kind of pigment has a better stability toward heat, metal ion and common food additives under acidic condition, and it is more tolerable of heat than light. The adsorption ability of D-072 resin was the best and the adsorptive rate of pigment reached 90.7%. When 50% ethanol contained 0.2% TFA was used as desorptive solvent, the pigment could be sufficiently desorpted and the effect of desorption would be better. It has a great prospect in the exploration and application in food industry to produce the food pigment from the fruit of Syzygium cumini.国家自然科学基金项目(30671646

补肾健脾方影响高脂肪饮食骨质疏松模型大鼠脂代谢及瘦素的变化

背景:绝经也可导致体内瘦组织与脂肪成分的改变,现阶段发现骨质疏松在肥胖的老年人中的发生率要大于非肥胖者,由此推断瘦素可能是骨质疏松症发病机制中的一个重要调节因素。目的:探讨补肾健脾方对高脂肪饮食骨质疏松大鼠脂代谢及瘦素的影响。方法:将6月龄SPF级雌性SD大鼠220只随机分成模型组170只和假手术组50只。模型组行双侧卵巢结扎切除术,假手术组除未行卵巢结扎切除外,其余步骤同模型组。手术后12周,模型鉴定成功后,手术组随机分成正常饮食模型组、高脂饮食模型组、高脂饮食健骨颗粒组和高脂饮食辛伐他丁组各40只。各组于术后第13周开始给药,健骨颗粒组给予健骨颗粒2 g/(kg·d),生理盐水2 mL溶解后灌胃,辛伐他丁组给予辛伐他丁100μg/(kg·d)灌胃,假手术组和正常饮食模型组以2 mL生理盐水灌胃,1次/d。于用药2,6,12,24周后测体质量,取血清、腰椎和股骨近端备用。双能X射线测定右侧胫骨骨密度,ELISA法测定血清骨钙素、血清抗酒石酸酸性磷酸酶5b(TRACT-5b)、总胆固醇、三酰甘油、瘦素、瘦素受体的水平,q PCR法测定大鼠骨组织瘦素、瘦素受体m RNA表达。结果与结论:①高脂饮食健骨颗粒组大鼠的体质量高于同期正常饮食模型组和高脂饮食模型组,但低于假手术组和高脂饮食辛伐他汀组,同时表达的瘦素、瘦素受体、骨钙素水平均高于正常饮食模型组和高脂饮食模型组,TRACT-5b、胆固醇、三酰甘油的浓度均低于正常饮食模型组和高脂饮食模型组,各组比较差异均有显著性意义(P <0.05);②结果表明,补肾健脾方可以调整大鼠脂代谢紊乱、降低血液黏滞度、改善血管壁结构的同时还能通过上调大鼠血清和骨组织中瘦素、瘦素受体的表达,改善大鼠骨代谢水平,防治原发性骨质疏松症。福建省自然科学基金(2017J01332),项目负责人:林煜;;福州市卫生系统科技项目(2017-S-wq15),项目负责人:李平~

DEGRADATION OF METHAMIDOPHOS BY MANGROVE SOIL MICROBES

连续 3年 (a)的试验结果表明 :红树林土壤微生物对农药甲胺磷有较强的降解能力 ,其降解率是同潮带无红树林土壤微生物的 2 - 3倍 ;红树林土壤中存在着降解甲胺磷的优势细菌类群 ,从中筛选得一株高效降解菌 ,其降解率可达 70 %以上 (12d后 ) ;混合菌的降解能力优于单株菌 ;优势降解菌在一定浓度的甲胺磷、适宜的通气、温度和光照等条件下 ,可发挥更佳的降解作用 ;在降解过程中 ,降解优势细菌类群有着明显菌群变化 ,那种一直占优势的菌株可选育为“工程菌” ;红树林土壤微生物具有多功能的环境效应和经济效益 .图 5表 5参 4Degradation of methamidophos by mangrove soil microbes was studied for successive three years. The results indicated: ① Mangrove soil microbes had a better ability of methamidophos degradation, and their degradation rate is 2～3 times higher than that of non-mangrove soil microbes. ② There were some dominant populations in mangrove soil, from which a high efficient strain was isolated; the degradation rate of the strain might be as high as 70% (after 12 days), however, the rate of mixed bacteria was higher than that of single strain. ③ The dominant bacteria had stronger degradation ability under a certain concentration of methamidophos, adaptive ventilation, temperature, and light . ④ The obvious changes of strains in dominant populations could be observed during the course of degradation, of which the "engineering strain” can be sifted out of the dominant strains from beginning to end. ⑤ Multiple environmental effects and economic benefits could be further verified in mangrove soil microbes as well.
