  • Procedure—Separately inject equal volumes (about 10 µL) of the Milkthistle standard solution, each of the Silybin standard solutions, andthe Test solution into the chromatograph, and record the chromatograms.Identify the peaks due to silychristin,silydianin, silybin A, silybin B, isosilybin A, and isosilybin B bycomparison with the chromatogram of the Milk thistle standard solution,and measure the peak areas of the relevant peaks.Plot the areas of the sum of silybin A and silybin B peaks versus theconcentration of USP Silybin RS in the Silybin standard solutions, andobtain a regression line for calibration. Separately calculate thepercentage of each relevant component of silymarin as silybin (C25H22O10) in the portion of Milk Thistle taken by the formula:

    250C/W

    in which C is the concentration, in mg per mL, of the relevant component in the Test solution as interpolated in the calibration graph;and W is the weight, in g, of the portion of Milk Thistle taken.Calculate the content of silymarin, in percentage, in the portion ofMilk Thistle taken by adding the individual percentages.

    以下是直接复制GOOGLE的翻译

    程序,另外注入(约10微升的牛奶)等体积蓟标准溶液,每个水飞蓟宾的标准解决方案,以及测试解决方案落入色谱仪,记录色谱图。确定峰由于silychristin,silydianin,水飞蓟宾甲,乙水飞蓟宾,isosilybin A和B的isosilybin与牛奶蓟色谱比较标准溶液,并测量有关峰的峰面积。情节方面总结了水飞蓟宾A和与水飞蓟宾的美国药典标准RS的水飞蓟宾浓度的水飞蓟宾乙峰的解决方案,并取得了校准回归线。分别计算各水飞蓟素为水飞蓟宾(C25H22O10相关组件的百分比)在由该公式采取的水飞蓟部分:

    250℃/ W型

    其中C是浓度,单位为毫克每毫升的测试解决方案在有关组成部分,在校准图插;和W是体重,在克的牛奶一部分,蓟措施。水飞蓟素含量计算,以百分比的比例加入个人采取奶蓟部分。

    程序--分别将大叶蓟(奶蓟?)标准溶液、每种水飞蓟宾标准溶液、以及测试溶液等体积(约10 µL)注入液相色谱仪,并记录色谱图。通过与大叶蓟标准溶液色谱图比较,鉴别出水飞蓟亭、水飞蓟宁、水飞蓟宾A、水飞蓟宾B、异水飞蓟宾A和异水飞蓟宾B,并测量相关峰的峰面积。将水飞蓟宾A与水飞蓟宾B峰面积的总数相对于水飞蓟宾标准溶液中USP水飞蓟宾标准品的浓度进行回归,得到一校正用的回归曲线。

    Separately calculate the percentage of each relevant component of silymarin as silybin (C25H22O10) in the portion of Milk Thistle taken by the formula这句话中的as不知道怎么理解,可否理解成“例如”?
    分别按下式计算所取大叶蓟中水飞蓟素的每一种相关成分(如水飞蓟宾C25H22O10)的百分比:

    怎么没有人来参与讨论呢?我不敢肯定是正确的,供参考吧

    250C/W
    in which C is the concentration, in mg per mL, of the relevant component in the Test solution as interpolated in the calibration graph;and W is the weight, in g, of the portion of Milk Thistle taken.
    式中,C为校正曲线图中以内插法求得的测试溶液中相关成分的浓度,以mg/ml为单位;W为所取大叶蓟的重量,以g为单位.

    最后这句就更是没有把握了:
    Calculate the content of silymarin, in percentage, in the portion ofMilk Thistle taken by adding the individual percentages.

    计算所取大叶蓟中水飞蓟素的含量,以百分比表示,by adding the individual percentages该怎么理解?

    不錯

    这是关键,as并非作「例如」解,应该是「以....」,「为....」等意思。「分别」的位置不正确



    从新翻译为:

    按下式分别计算所取大叶蓟中水飞蓟素的每一种相关成分为水飞蓟宾C25H22O10)的百分比

    由于silymarin 是由不同的silybin (C25H22O10)所组成,所以必须把个别的silybin 百分比加起来才得到最后结果
