Papain, a natural plant protease that exists in the latex of Carica papaya, catalyzes hydrolysis peptide, ester and amide bonds. In this work, we found papain displayed peroxidase-like activity catalyzed oxidation 3,3',5',5'-tetramethylbenzidine (TMB) presence H2O2. This results formation blue colored product with an absorption maximum at 652 nm. The effects experimental parameters including pH reaction temperature on catalytic were investigated. increase absorbance induced by effect offers...
The synthesis of AuNPs@MoS 2 NSs was achieved and the sensing biothiols carried out using as enzyme mimics.
Abstract A rapid and sensitive ultrahigh‐performance liquid chromatography–tandem mass spectrometry method was developed validated for simultaneous determination of 15 bioactive ingredients in rat plasma tissues after oral administration Polygonum chinense Linn extract (PCE). After addition internal standards (ISs; rutin danshensu), tissue samples were pre‐treated by protein precipitation with acetonitrile–ethanol. The chromatographic separation performed on an Agilent ZORBAX RRHD Eclipse...
摘要: 建立了基于月桂酰基苹果酸酯的胶束电动色谱-质谱法同时分离测定牛黄上清片中黄连碱、小檗碱、药根碱、黄柏碱以及川芎嗪5种有效成分含量的新方法。以7.5 mmol/L月桂酰基苹果酸酯-15 mmol/L氨水-50 mmol/L醋酸铵(含12.5%的乙腈,pH=7.0)为电泳介质,未涂层弹性石英毛细管(88 cm×50 μm)为分离通道,50%异丙醇水溶液(含3 mmol/L乙酸)为鞘液,在25 kV的运行电压下,各组分可以在18 min内得到基线分离。各组分的浓度与其峰面积呈现良好的线性关系,迁移时间和峰面积的相对标准偏差均小于5%,样品中5种生物碱成分的样品加标回收率在96.0%~105%之间。该法简便、快速、准确、重现性好,可用于牛黄上清片中这5种有效成分含量的同时测定。
Using caffeic acid and icariin as internal standards, a method for the simultaneous determination of protocatechuic acid, aldehyde, chlorogenic scutellarin, isochlorogenic C, baicalin, luteolin, apigenin, atractylenolide III I in Fufangxingxiangtu' erfeng capsules were established by ultra performance liquid chromatography with tandem mass spectrometry (UPLC-MS/MS). The separation was performed on ZORBAX RRHD Eclipse Plus C18 column (50 mm x 2.1 mm, 1.8 microm) using water containing 0.3%...
Young fruits of seven loquat cultivars (Eriobotrya japonica Lindl.) were treated at 0, -3, -6, and 7°C for 12, 24, 48 h. The physiological biochemical indices measured to reveal the cold hardiness selections. Cold was assessed using principal component analysis subordinate function value analysis. response patterns treatments in fruit flesh embryos basically same accessions. According logistic equations, half lethal temperatures accessions ranged from -3.2° -6.7°C (fruit flesh) -3.5°...
