  • 【Identification】

(1) Cross-section of this product: The epidermis is remnant, and the hypodermis is composed of 2-3 rows of tangentially elongated suberized cells. The cortex is composed of 10 rows of polygonal cells, some of which contain bundles of calcium oxalate needles. The junction between the cortex and the hypodermis of older tubers has 2-3 rows of oval thick-walled cells, which are lignified and have obvious pits. The pith occupies the majority, with small circumflex vascular bundles scattered; the thin-walled cells also contain bundles of calcium oxalate needles. The powder is yellow-white to yellow-brown. The thick-walled cells are elliptical or sub-polygonal, with a diameter of 70-180 μm, a wall thickness of 3-8 μm, lignified, and obvious pits. The calcium oxalate needles are bundled or scattered, 25-75 (93) μm long. The thin-walled cells containing gelatinized polysaccharides are colorless when mounted with glycerol acetic acid test solution. Some cells can be seen as long oval, long oval or sub-round particles, which appear brown or light brown purple when exposed to iodine solution. The diameter of the spiral vessels, reticular vessels and annular vessels is 8-30 μm. (2) Take 1 g of the powder of this product, add 10 ml of methanol, ultrasonically treat for 30 minutes, filter, concentrate the filtrate to dryness, add 1 ml of methanol to dissolve the residue, and use it as the test solution. Take 1 g of Gastrodia elata control medicinal material and prepare the control medicinal material solution in the same way. Then take the reference gastrodin, add methanol to make a solution containing 1 mg per 1 ml, as the reference solution. According to the thin layer chromatography method (general rule 0502), take 10R of the test solution and the reference medicinal material solution, and 5R of the reference solution, and spot them on the same silica gel G thin layer plate, respectively, with dichloromethane-ethyl acetate-methanol-water (2:4:2.5:1) as the developing agent, develop, take out, dry, spray with p-hydroxybenzaldehyde solution (take 0.2g of p-hydroxybenzaldehyde, dissolve in 10ml of ethanol, add 1ml of 50% sulfuric acid solution, mix well), heat at 120℃ until the spots are clearly colored, and inspect under sunlight. In the chromatogram of the test sample, spots of the same color appear at the corresponding positions of the chromatogram of the reference medicinal material and the chromatogram of the reference substance.

Preparation of reference solution Take about 0.5g of Gastrodia elata reference medicinal material, place it in a stoppered conical flask, add 25ml of 50% methanol, ultrasonically treat (power 500W, frequency 40kHz) for 30 minutes, cool, shake well, filter, and take the filtrate as the reference solution of the reference medicinal material. Take the reference solution under [Content determination] as the reference solution of the reference material.
Preparation of test solution Take about 0.5g of this product powder (passed through No. 4 sieve) and prepare the test solution in the same way as the preparation method of the reference solution of the reference medicinal material. Determination method Accurately aspirate 30% of the reference solution and the test solution respectively, inject into the liquid chromatograph, determine, and record the chromatogram to obtain. There should be 6 characteristic peaks in the chromatogram of the test sample, and they should correspond to the 6 characteristic peaks in the chromatogram of the reference medicinal material. Among them, peak 1 and peak 2 should be consistent with the retention time of the reference peaks of the gastrodin reference substance and the p-hydroxybenzyl alcohol reference substance.

Chromatographic conditions and system suitability test: Octadecylsilane bonded silica gel is used as filler; acetonitrile-0.05% phosphoric acid solution (3:97) is used as mobile phase; the detection wavelength is 220nm, and the theoretical plate number calculated based on the gastrodin peak should not be less than 5000. Preparation of reference solution Take appropriate amount of gastrodin reference and p-hydroxybenzyl alcohol reference, weigh accurately, add acetonitrile-water (3:97) mixed solution to make a mixed solution containing 50 mg of gastrodin and 25 mg of p-hydroxybenzyl alcohol per 1 ml, and obtain the solution. Preparation of test solution Take about 2 g of this product powder (passed through No. 3 sieve), weigh accurately, place in a stoppered conical bottle, accurately add 50 ml of dilute ethanol, weigh the weight, ultrasonically treat (power 120W, frequency 40kHz) for 30 minutes, cool, weigh again,
make up the lost weight with dilute ethanol, filter, accurately measure 10 ml of the filtrate, concentrate to near dryness without alcohol taste, dissolve the residue with acetonitrile-water (3:97) mixed solution, transfer to
a 25 ml volumetric flask, dilute to scale with acetonitrile-water (3:97) mixed solution, shake well, filter, and take the filtrate, and obtain the solution. Determination method: Accurately pipette 50% of the reference solution and 50% of the test solution, inject them into the liquid chromatograph, and determine them.
