distinguish
(1) Cross section of this product: the cork layer is 10 ~ 15 rows of cork cells. The phloem is scattered in a small amount of calcium oxalate cubes and oil cells. The long diameter of oil cells is 52 ~ 122 microns, and the short diameter is 28 ~ 87 microns. There are lignified fibers at the outer edge of phloem, single or 2 ~ 5 in groups. The xylem vessel is 35 ~ 98 microns in diameter and surrounded by fiber bundles. There are 1 ~ 3 rows of single pit cells. Thin-walled cells are filled with starch granules.
(2) Take 65,438+0g of Zanthoxylum nitidum reference medicinal material, add 65438±05ml of ethanol, soak in warm water for 30min, perform ultrasonic treatment for 30min, filter, evaporate the filtrate to dryness, and add 65438±0ml of ethanol to dissolve the residue as reference medicinal material solution. According to the thin-layer chromatography test (Appendix ⅵ b), suck 2μl of reference medicinal solution, and suck 2 μ l of test solution and reference solution under [Content Determination], and spot them on the same silica gel G thin-layer plate respectively, and test the solution with benzene-ethyl acetate-methanol-isopropanol-concentrated ammonia water (20: 5: 3:1:0./kloc-0. In the chromatogram of the test sample, fluorescent spots with the same color appear at the positions corresponding to the chromatogram of the control medicinal materials; At the position corresponding to the chromatogram of the reference substance, the same light yellow fluorescent spots appeared.
(3) Take the reference substance of ethoxychelerythrine and add methanol to make a solution containing 65438±0mg per 65438±0ml as the reference substance solution. According to the thin-layer chromatography test (Appendix ⅵ b), 2μl of reference solution, 2 μ l of reference medicinal solution and 2 μ l of test solution were put on the same silica gel G thin-layer plate, and toluene-ethyl acetate-methanol (25:2:0. 1) was used as the developing agent, and the concentrated ammonia solution was pre-saturated. In the chromatogram of the test sample, fluorescent spots with the same color appear at the positions corresponding to the chromatogram of the control medicinal materials; At the position corresponding to the chromatogram of the reference substance, the same orange fluorescent spots are displayed.
Content determination
Take the coarse powder of this product about 1g (meanwhile, take another powder of this product to measure moisture (appendix ⅸ h, the first method), weigh it accurately, put it in Soxhlet extractor, add methanol 100ml, and heat and reflux to extract until the reflux liquid is colorless. Recover methanol from the extractive solution to about 2ml, transfer it to a 10ml volumetric flask, add methanol to the scale, and shake it evenly as the test solution. In addition, take an appropriate amount of nitidine chloride reference substance, weigh it accurately, and add methanol to make a solution containing 0.5mg per kloc-0/ml as the reference substance solution. According to the thin-layer chromatography test (Appendix ⅵ b), with sodium carboxymethyl cellulose as adhesive and benzene-ethyl acetate-methanol-isopropanol-concentrated ammonia solution (20: 5: 3: 1: 0.65438+), 4μl of test solution, reference solution 1μl and reference solution 4μl were accurately absorbed respectively.
Scanning with thin-layer chromatography (appendix ⅵ b thin-layer scanning method), wavelength: λS=300nm, λR=2 10nm, measuring the absorbance integral value of the test sample and the absorbance integral value of the control sample, and calculating.
In terms of dry product, this product shall not be less than 0.25% in terms of nitidine (C 21H18NO 4).
Bitter, pungent and flat in nature; A little poisonous. Entering the liver and stomach meridians.
Its main functions are promoting qi circulation to relieve pain, promoting blood circulation to remove blood stasis, expelling wind and dredging collaterals. Used for traumatic injury, rheumatic joint pain, stomachache, toothache and poisonous snake bite caused by qi stagnation and blood stasis; External treatment of scald caused by soup and fire.
