  • 【Identification】

(1) Cross section of this product: The cork layer is composed of several rows of cells. The inner layer of the cork is narrow, with a few oil chambers. The phloem is broad and fissured, with oil chambers and oil tubes that are circular, 25 to 160 μm in diameter, larger on the outside and gradually smaller inward, surrounded by 6 to 9 secretory cells. The cambium is ring-shaped. The xylem rays are 3 to 5 rows of cells wide; the vessels are scattered singly or 2 to 3 are gathered together and arranged radially; the thin-walled cells contain starch grains. The powder is light yellow-brown. The phloem thin-walled cells are spindle-shaped, with slightly thick walls, and very fine oblique interlaced textures on the surface, and sometimes thin transverse septa can be seen. Scalar vessels and reticulate vessels are common, with a diameter of about 80 μm. Sometimes oil chamber fragments can be seen.
(2) Take 0.5 g of the powder of this product, add 20 ml of acetyl, ultrasonically treat for 10 minutes, filter, evaporate the filtrate to dryness, add 1 ml of ethanol to dissolve the residue, and use it as the test solution. Take 0.500 of Angelica sinensis control medicinal material and prepare the control medicinal material solution in the same way. According to the thin layer chromatography method (General Rule 0502), 100 ml of each of the above two solutions were taken and spotted on the same silica gel G thin layer plate, and developed with n-hexane-ethyl acetate (4:1), taken out, dried, and examined under ultraviolet light (365 min). In the chromatogram of the test sample, fluorescent spots of the same color appeared at the corresponding positions of the chromatogram of the reference medicinal material.
(3) Take 3g of the powder of this product, add 50ml of 1% sodium bicarbonate solution, ultrasonically treat for 10 minutes, centrifuge, take the supernatant and adjust the pH value to 2-3 with dilute hydrochloric acid, shake and extract with acetaldehyde twice, 20ml each time, combine the acetic acid solution, evaporate to dryness, add 1ml of methanol to the residue to dissolve, and use it as the test solution. Separately take the ferulic acid reference substance and the ligustilide reference substance, add methanol to make a solution containing 1mg of each per 1ml, and use it as the reference solution. According to the thin layer chromatography method (General Rule 0502), 10R of each of the above three solutions were taken and spotted on the same silica gel G thin layer plate, and cyclohexane-dichloromethane-ethyl acetate-formic acid (4:1:1:0.1) was used as the developing agent. After development, the plate was taken out, dried, and inspected under ultraviolet light (365nm). In the chromatogram of the test sample, fluorescent spots of the same color appeared at the corresponding positions of the chromatogram of the reference sample.
[Inspection] Water content shall not exceed 15.0% (General Rule 0832 Method 4).
Total ash content shall not exceed 70% (General Rule 2302).
Acid insoluble ash content shall not exceed 20% (General Rule 2302).
Heavy metals and harmful elements are determined according to the lead, cadmium, arsenic, mercury and copper determination method (General Rule 2321 atomic absorption spectrophotometry or inductively coupled plasma mass spectrometry). Lead shall not exceed 5mg/kg; cadmium shall not exceed 1mg/kg; arsenic shall not exceed 2mg/kg; mercury shall not exceed 0.2mg/kg; copper shall not exceed 20mg/kg.

Preparation of reference solution Take an appropriate amount of ferulic acid reference, accurately weigh it, put it in a brown volumetric bottle, add 70% methanol to make a solution containing 12μg per 1ml, and the solution is obtained. Preparation of test solution Take about 0.2g of the powder of this product (passed through No. 3 sieve), accurately weigh it, put it in a stoppered conical bottle, accurately add 20ml of 70% methanol, stopper it, weigh it, heat and reflux for 30 minutes, cool it, weigh it again, make up the lost weight with 70% methanol, shake it well, let it stand, take the supernatant to filter, and take the filtrate to obtain it. Determination method: Accurately pipette 10R of reference solution and test solution respectively, inject into liquid chromatograph, and determine. This product contains not less than 0.050% of ferulic acid (C10 H10 O4) calculated on the basis of dry product.
