鉴别 Identification
取本品粉末3g,加甲醇30ml,超声处理30分钟,滤过,滤液蒸干,残渣加水20ml使溶解,用三氯甲烷30ml振摇提取,分取三氯甲烷液,蒸干,残渣加乙酸乙酯2ml使溶解,作为供试品溶液。另取榧子对照药材3g,同法制成对照药材溶液。照薄层色谱法(通则0502)试验,吸取上述两种溶液各2μl,分别点于同一硅胶G薄层板上,以石油醚(60~90℃)-乙酸乙酯(8:2)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,分别置日光和紫外光灯(365nm)下检视。供试品色谱中,在与对照药材色谱相应的位置上,显相同颜色的斑点或荧光斑点。
To 3 g of the powder add 30 ml of methanol, ultrasonicate for 30 minutes, filter, and evaporate the filtrate to dryness. Dissolve the residue in 20 ml of water, and extract by shaking with 30 ml of chloroform. Evaporate the chloroform extract to dryness and dissolve the residue in 2 ml of ethyl acetate as the test solution. Prepare a solution of 3 g of Torreyae Semen reference drug in the same manner as the reference drug solution. Carry out the method for thin layer chromatography <0502>, using silica gel G as the coating substance and a mixture of petroleum ether (60-90℃)-ethyl acetate (8 : 2) as the mobile phase. Apply separately 2 μl of each of the above two solutions to the plate. After developing and removal of the plate, dry in air, spray with a 10% solution of sulfuric acid in ethanol, heat at 105℃ until the colour of the spots appear distinctly. The spots in the chromatogram obtained with the test solution correspond in position and colour to the spots in the chromatogram obtained with the reference drug solution. Examine under ultraviolet light at 365 nm, the fluorescent spots in the chromatogram obtained with the test solution correspond in position and colour to the spots in the chromatogram obtained with the reference drug solution.
