    • 取本品2 g,除去盖衬,剪成小块,置锥形瓶中,加水5 ml,再加入水饱和后的正丁醇30 ml,振摇,静置过夜,滤过,滤液加3倍量以正丁醇饱和的水,摇匀,放置使分层,取正丁醇层,蒸干,残渣加甲醇1 ml使溶解。另取三七总皂苷,加甲醇制成每1 ml含0.5 mg的溶液。按照薄层色谱法(中国药典2020年版四部通则0502)试验,吸取上述两种溶液各5μl,分别点于同一硅胶G薄层板上,以三氯甲烷-乙酸乙酯-甲醇-水 (15∶40∶22∶10)10 ℃以下放置的下层溶液为展开剂,展开,取出,晾干,喷以10 %硫酸乙醇溶液,在105 ℃加热至斑点显色清晰。供试品色谱中,在与对照品色谱相应的位置上,显相同颜色的斑点;置紫外光灯(365nm)下检视,显相同的荧光斑点。阴性试验样品未见干扰,见图3

    • 色谱柱:Promosil C18柱(250 mm×4.6 mm,5 μm);以乙腈为流动相A,水为流动相B,梯度洗脱:0~5 min,23% A;5~68 min,23%~33% A。柱温为35 ℃,流速为1.0 ml/min;检测波长为203 nm;进样体积为10 μl。在此条件下,样品中三七皂苷R1、人参皂苷Rg1、人参皂苷Rb1与相邻峰达到良好分离,见图4

    • 取三七皂苷R1、人参皂苷Rg1、人参皂苷Rb1对照品适量,精密称定,加甲醇制成每1 ml中分别含0.08、0.4、0.36 mg的混合溶液,即得。

    • 取本品约2 g,除去盖衬,剪成小块,精密称定,置具塞锥形瓶中,加入甲醇50 ml,加热回流2 h,摇匀,滤过。再用15 ml甲醇荡洗锥形瓶,滤过,合并滤液并蒸干,残渣加水15 ml,以水饱和的正丁醇振摇提取4次,每次20 ml,合并正丁醇液,用氨试液洗涤2次,每次20 ml,合并正丁醇液,蒸干,残渣加甲醇溶解并转移至10 ml量瓶中,加甲醇至刻度,摇匀,滤过,取续滤液,即得。

    • 按处方量配制不含三七药材的阴性样品,按供试品溶液方法制备阴性对照溶液。

    • 取对照品溶液、供试品溶液、阴性对照溶液,按“2.2.1”项下色谱条件进样分析,阴性对照液中色谱峰对测定无干扰(见图4)。

    • 取三七皂苷R1、人参皂苷Rg1、人参皂苷Rb1对照品适量,加甲醇溶解制成每1 ml 分别含0.8019、4.0014、3.0913 mg的混合对照品储备溶液6,将溶液6稀释如下: 0.2 ml→10 ml、0.5 ml→10 ml、1 ml→10 ml、2 ml→10 ml、2.5 ml→10 ml作为对照品溶液1~5,精密吸取上述对照品溶液1~5各10μl,注入液相色谱仪,按“2.2.1”项下色谱条件测定峰面积,以进样量(μg)为横坐标(X),峰面积(Y)为纵坐标,进行线性回归,分别得到三七皂苷R1、人参皂苷Rg1和人参皂苷Rb1的回归方程:

    • 按“2.2.3”项下方法制备供试品溶液,按“2.2.1”项下色谱条件测定3批样品,结果见表2

    • 三七总皂苷为三七药材的主成分,参照2020版《中国药典》[1],以三七药材方法项下紫外吸收203 nm作为最大吸收。

    • 分别取待测样品1、2、3 g,加入不同浓度乙醇、甲醇,回流1、2、3 h和冷浸24 h,采用氨试液洗涤样品等方法提取样品。结果表明,最终选择取样量为2 g,甲醇为溶剂,氨试液洗涤,并按照正文的含量测定项下方法进行测定提取较完全。

    • 按照“2.2.3”项下供试品溶液的制备,分别在不同柱温30、35、40℃,不同梯度流动相比例条件(0~5 min,23 % A;5~63 min,23%~34 % A与0~5 min,23 % A;5~68 min,23%~33 % A)下,不同色谱柱InertSustainC18 (150 mm×4.6 mm, 5 μm)与Promosil C18柱(250 mm×4.6 mm,5 μm),测定三七总皂苷含量。在各试验条件下,待测成分的分离较好,测定结果基本一致,耐用性良好。

    •   建立景天止痛膏制剂中当归、川芎、元胡、三七总皂苷的薄层色谱鉴别方法,拟增加肉桂的薄层实验中,因存在阴性试验样品有干扰的问题,故未列入本文。对TLC方法,分别从温度(10℃和35℃)、相对湿度(42%和88%)以及不同硅胶板(国产和进口)等方面进行考察。在各试验条件下,鉴别结果 不受温度、相对湿度和不同硅胶板等条件改变的影响。说明本文所建立的薄层色谱方法作为定性鉴定方法具有很强的适用性。
