楼主好象求助过前面部分的相关内容。注射液的通则内容太多,没时间看,楼主先自行翻译吧。

Assay—

Mobile phase— Prepare a filtered and degassed mixture of 0.04Maqueous monobasic potassium phosphate and methanol (55:45).Make adjustments if necessary (see System Suitabilityunder Chromatography á621ñ).

Internal standard solution— Prepare a solution of methylparaben in Mobile phasehaving a concentration of about 100µg per mL.

Standard preparation— Prepare a solution of USP Thiamine Hydrochloride RSin Mobile phasehaving an accurately known concentration of about 500µg per mL.Pipet 10mLof this solution and 10mLof Internal standard solutioninto a 100-mLvolumetric flask,dilute with Mobile phaseto volume,and mix to obtain a Standard preparationhaving a known concentration of about 50µg per mL.

Assay preparation— Quantitatively dilute an accurately measured volume of Oral Solution with Mobile phaseto obtain a solution containing about 500µg of thiamine hydrochloride per mL.Pipet 10mLof the resulting solution and 10mLof Internal standard solutioninto a 100-mLvolumetric flask,dilute with Mobile phaseto volume,and mix.

流动相 - 0.04M的磷酸二氢钾水溶液与甲醇以55:45的比例混合后,过滤、脱气。如有必要,可适当调整(看色谱技术<621>项下的系统适用性)。

内标溶液用流动相制备浓度为100µg/mL的对羟基苯甲酸甲酯溶液。

标准溶液 -用流动相制备含准确浓度约为500µg/mLUSP维生素B1溶液。取此溶液10ml及内标溶液10ml,置于100ml量瓶中,用流动相稀释至刻度,混匀后得到一已知浓度约为50µg/mL的标准溶液。

含量测试溶液准确量取一定体积的口服溶液,用流动相定量稀释成含维生素B1约为500µg/mL的溶液。取此溶液10ml及内标溶液10ml,置于100ml量瓶中,用流动相稀释至刻度,混匀。

Chromatographic system(see Chromatography á621ñ)— The liquid chromatograph is equipped with a 254-nm detector and a 3.9-mm ×30-cm column that contains packing L1.The flow rate is about 1.0mLper minute.Chromatograph the Standard preparation,and record the peak responses as directed for Procedure:the relative retention times are about 0.35for thiamine and 1.0for methylparaben;the resolution,R,between the thiamine and methylparaben peaks is not less than 6.0;and the relative standard deviation for replicate injections is not more than 2.0%.

Procedure— Separately inject equal volumes (about 25µL)of the Standard preparationand the Assay preparationinto the chromatograph,record the chromatograms,and measure the responses for the major peaks.Calculate the quantity,in mg,of thiamine hydrochloride (C12H17ClN4OS·HCl)in each mLof the Oral Solution taken by the formula: C(L/D)(RU/RS)

C(L/D)(RU/RS),

in which Cis the concentration,in mg per mL,of USP Thiamine Hydrochloride RSin the Standard preparation;Lis the labeled quantity,in mg per mL,of thiamine hydrochloride in the Oral Solution;Dis the concentration,in mg per mL,of thiamine hydrochloride in the Assay preparationon the basis of the labeled quantity and the extent of dilution;and RUand RSare the ratios of the peak responses of thiamine to methylparaben obtained from the Assay preparationand the Standard preparation,respectively.

(Official June 1,2005)

色谱系统(看色谱技术<621>- 液相色谱的检测器波长为254nm,色谱柱型号为3.9mm×30cm,填料为L1。流速约为1.0ml/min。将标准溶液进行色谱分析,并按下面的程序记录峰响应值:硫胺的相对保留时间约为0.35,对羟基苯甲酸甲酯的相对保留时间约为1.0;硫胺与对羟基苯甲酸甲酯峰之间的分离度不低于6.0;且重复进样的相对标准偏差不大于2.0%

程序 - 分别将等体积(约25µL)的标准溶液与含量测试溶液注入液相色谱仪,记录色谱图并测量主峰的响应值。按下式计算每ml口服溶液中维生素B1(C12H17ClN4OS·HCl)的量,以mg表示:

式中:C表示标准溶液中USP维生素B1的浓度(mg/ml);L表示口服溶液中维生素B1的标示量(mg/ml);D表示含量测试溶液中基于标示量与稀释倍数的维生素B1盐酸盐的浓度(mg/ml[这句话译得不太顺畅,意思是不能仅仅将含量测试溶液的最终浓度代入公式计算,还需要考虑稀释倍数]RURS分别表示含量测试溶液与标准溶液中所测得的维生素B1与对羟基苯甲酸甲酯峰响应值的比值。

俺知道,我俺发过贴。为不了让大家给白帮忙翻译所以才悬赏的,因为俺这药典这块实在是差的太多,所以才拜托给弄一下,以后不会了,因为我们公司给找专门翻译的了!
