Studies on the Analysis of Alkaloidal Extract Preparations——Ⅱ.Determination of Nux Vomica Preparations by Thin-layer Chromatography-catalytic Polarographic Method
For the multiple dosing, the AUC 0→t were (686.1±253.3)ng/h·mL and (675.0±262.9)ng/h·mL, and the relative bioavailability for the domestic formulation was 102.9%±13.8%(n=18).
LD50(ip)=1461.65mg kg-1, A=-20.94, B=7.41.Compared with effective dosage (12.5 ~ 150 mg kg-1) , the acute toxicity of BCEF is low and it's an security agent.
In order to investigate the effects of diet with compound enzyme agent Viscozyme L on the rex-rabbit growth,40 healthy rex-rabbits about forty-day old were divided into 4 groups randomly,which were fed with diets adding 0,0.05%,0.1% and 0.2% compound enzyme respectively.
The details of the synthetic sequence followed for the preparation of all these compounds having almost all the structural features required for a compound to act as a potent insulin sensitizing agent are reported.
The overall process involves three steps: preparation of insoluble carboxyl-containing grafted starch copolymer (ISC), formation of precursor (ISC-Co), decomposition of ISC-Co, and phase transition of Co3O4 nanoparticles.
In this paper, a new preparation method of 3,5-dinitrobenzoyl-bonded silica gel stationary phase (DNB) for HPLC was developed by using N-(β-aminoethyl)-γ-aminopropyl-methyldimethoxy silane as coupling reagent.
25S and 5S rDNA were labeled as probes with DIG-Nick Translation Mix kit and Biotin-Nick Translation Mix kit, respectively, in situ hybridized to mitotic preparations, where 25S rDNA could be detected on two chromosome pairs and 5S rDNA on only one.
A laboratory reactor equipped with a screw press was used for the hydrolysis of steam-SO2-exploded willowSalix caprea by a composition ofTrichoderma reesei andAspergillus foetidus enzyme preparations at high substrate concentration.
The possibility of using xylanase preparations for hydrolyzing hemicelluloses in a non-bleached kraft pulp in order to facilitate its bleaching was studied.
As an application of this abstract formulation, a constructive procedure is developed, which produces all wavelet sets in ?nrelative to an integral expansive matrix.
Transfersomal formulation with optimal concentration of Soya phosphatidylcholine (SPC) and sodium deoxycholate (85:15 w/w) showed entrapment efficiency of 39.8±0.032 and deformability index of 16.4.
This formulation is uniformly coercive and not subject to the Babu>amp;gt;ska-Brezzi condition, and the resulted linear algebraic system is positive definite with the spectral condition number O(h-2).
The details of the synthetic sequence followed for the preparation of all these compounds having almost all the structural features required for a compound to act as a potent insulin sensitizing agent are reported.
9-O-methylfusarubin was isolated from a novel source, Fusarion oxysporum, and evaluated for its phytotoxic and chlorotic inducing properties in plants as well as its potential as an antineoplastic agent.
The enantiomeric excess of the reduction product was up to 83.2% with cyclohexane as the solvent, the molar ratio of ligand: reductive agent: β-acetonaphthalene is 0.04:1.6:1, and 72-hours reaction time at 0°C.
A highly cross-linked structure was formed in both the cores and the shells by using a cross-linking agent, which could prevent the migration of hydrophobic PS shells to the inside of particles.
Benzoxycarbonyl chloride was selected as amino group protection agent, and the yield was elevated by replacing sodium bicarbonate with triethyl amide as the acid's neutralizer.
