 [Source] product Umbelliferae Cnidium Cnidium monnieri (L.) Cuss.'s Dried ripe fruit. Summer and autumn harvest mature fruit, remove impurities, dried in the sun. 

 【Properties】 This product is double-hanging fruit, oval-shaped, length 2 ~ 4mm, diameter of about 2mm. Surface greyish yellow or brown, the top two outward curved plinth, base occasionally thin stems. If the back of a thin sub-processes of the longitudinal edges 5, flat joints, there are two brown longitudinal ridge protruding slightly. Fruit crisp, easy to rub off, seeds small, gray-brown, was oily. Air fragrant, spicy cool, Ma tongue feeling. 

 [Identification] 
 (1) cross-section of the product sub-fruit: epicarp of a flat cell, outside the cuticle. Mesocarp thick, vertical edge very prominent, with the central vascular bundle, surrounded by a thick wood of the textured cells; the back of the vertical edges between each oval tubing 1, 2 tubing joints have a total of six. Endocarp of a flat cell. Seed coat is a pale brown cells. Most of aleurone endosperm cells containing each aleurone contains small clusters of calcium oxalate crystals. 
 (2) of this product powder 2g, add ethanol 20ml, refluxed 30 minutes, and filtration. The filtrate a few drops of white points on the board, UV light (365nm) were observed, significantly blue-violet fluorescence; alternative filtrate 2ml, plus the same amount of 3% sodium carbonate solution, heat 5 minutes, let cool, then plus the new system of p-nitroaniline diazonium 1 to 2 drops of test solution, which was cherry red. 
 (3) of this product meal 0.3g, plus ethanol, 5ml, ultrasound for 5 minutes, place, and the supernatant as the test solution. Alternative Osthol reference substance, add ethanol made 1mg per 1ml of the solution, as the reference solution. According to TLC (appendix Ⅵ B) experiment, to learn the two solutions of 2μl, respectively, at the same point of sodium carboxymethyl cellulose as a binder of silica gel G plate with benzene - ethyl acetate (30 : 1) the agent, started out, drying, UV light (365nm), under review. Test products for chromatography, chromatography with reference substance corresponding position, substantially the same color of the fluorescent spots. 

 Content determination 
 Precision Weigh phosphorus pentoxide desiccator vacuum dried to constant weight of the product powder (over on the 3rd screen) 1g, set conical flask with stopper, precision ethanol 20ml, after shaking overnight, filtration , the filtrate obtained, as the test solution. Alternative Osthol appropriate reference substance, accurately weighed, add ethanol made 1mg per 1ml of the solution, as the reference solution. According to TLC (appendix Ⅵ B) experiment, precise drawing of the two solutions of 1μl, respectively, crossing at the same silica gel G plate with benzene - ethyl acetate (30:1) as the agent, removed, dried. According to thin layer chromatography (TLC Annex Ⅵ B) fluorescence scanning, excitation wavelength: λ = 365nm, test and reference substance measured fluorescence intensity and calculating, that too. 
 This product contains osthole (C15H16O3) not less than 1.0%. 

 [Taste] Sim, bitter, warm; a small drug.
