  • 【Identification】

(1) The powder of this product is yellow-white. There are many starch granules, single grains are spherical, polygonal, oval or helmet-shaped, with a diameter of 3 to 25 μm, and are called navel-shaped, crack-shaped, cross-shaped, trident-shaped, star-shaped or herringbone-shaped; complex granules are mostly composed of 2 ~12 pieces. The diameter of reticulated conduit and threaded conduit is 10~85μm. Cork cells are polygonal or quasi-rectangular, light yellowish brown. Most of the oil pipes are broken and contain light yellowish-brown secretions.

(2) Take 0.5g of this product powder, add 10ml of ethyl acetate, soak for 1 hour, shake frequently, filter, evaporate the filtrate to dryness, add 1ml of ethyl acetate to the residue to dissolve, and use it as the test solution. Take another 0.5g of Angelica dahurica as the reference medicinal material and prepare the reference medicinal material solution in the same way. Then take imperatorin reference substance and isoimperatorin reference substance, add ethyl acetate to make each

1ml of mixed solutions each containing 1mg was used as the reference solution. According to the thin layer chromatography (General Chapter 0502) test, draw 4R of each of the above three solutions, and point them on the same silicon

On the glue G thin layer plate, use petroleum solution (30~60°C)-ethyl alcohol (3:2) as the developing agent, develop it below 25°C, take it out, dry it, and inspect it under an ultraviolet light (365nm). In the chromatogram of the test product, fluorescent spots of the same color appear at positions corresponding to the chromatogram of the control medicinal material and the reference substance. Above, fluorescent spots of the same color are displayed.

  • 【Content determination】

Determine according to high performance liquid chromatography (General Chapter 0512). Chromatographic conditions and system suitability test using octadecylsilane bonded silica gel

as the filler; use methanol-water (55:45) as the mobile phase; the detection wavelength is 300nmo and the number of theoretical plates should not be less than 3000 based on the imperatorin peak.

Preparation of the reference substance solution: Take an appropriate amount of imperatorin reference substance, weigh it accurately, add methanol to make a solution containing 10% of the solution per 1ml, and you have it.

Preparation of the test solution: Take about 0.4g of this product powder (passed through No. 3 sieve), weigh it accurately, put it in a 50ml measuring bottle, add 45ml of methanol, ultrasonic treatment (power 300W, frequency 50kHz) for 1 hour, take it out and put it Cool, add methanol to the mark, shake well, filter, and take the remaining filtrate to obtain.

The measurement method is to accurately absorb 200% each of the reference solution and the test solution, inject them into the liquid chromatograph, and measure. Calculated as dry product, this product contains imperatorin (C16H14) not less than 0.080%.
