After soaking the wheat flour in field water, keep it warm and mixed, and dry it in the sun or at low temperature when the sprouts grow to about 5mm. 【Character】 This product is fusiform, with a length of 8~12mm and a diameter of 3~4mm. The surface is light yellow, the back is surrounded by lemma and has 5 veins; the ventral surface is surrounded by lemma. After removing the lemma and lemma, there is a longitudinal groove on the ventral surface; young shoots and fibrous roots grow at the base of the radicle, and the young shoots are lanceolate and strip-shaped, about 5 mm long. There are several fibrous roots, slender and curved. It is hard, white in cross-section and powdery. The smell is slight and the taste is slightly sweet. 【Identification】 (1) The powder of this product is not off-white. The single starch granules are round, with a diameter of 3~60um, and the umbilical point is herringbone or slit-shaped. On the surface of the outer epidermis of the lemma, long cells and two short cells (suberized cells and siliceous cells) are arranged alternately; the long cells have thick walls, tightly and deeply wavy curves, and the short cells are round-shaped with sparse wall holes. The non-glandular hairs of wheat awns are slender and mostly broken; the non-glandular hairs on the epidermis of the lemma are thinner and 80~230um long; the scales are non-glandular. Hairy cone shape, slightly thicker wall, 30~110um long. (2) Take 5g of this product powder, add 30ml of absolute ethanol, ultrasonicate for 40 minutes, filter, add 1.5ml of 50% potassium hydroxide solution to the filtrate, heat to reflux for 15 minutes, cool in an ice bath for 5 minutes, and use petroleum ether (30~60°C) Shake and extract 3 times, 10ml each time, combine the petroleum ether liquid, evaporate to dryness, add 1ml of ethyl acetate to the residue to dissolve, and use it as the test solution. Take another 5g of malt reference medicinal material and prepare the reference medicinal material solution in the same way. According to the thin layer chromatography (General Chapter 0502) test, absorb 2μ1 of each of the above two solutions, respectively point on the same silica gel G thin layer plate to form a strip, and use toluene-chloroform-ethyl acetate (10:10: 2) Use toluene-chloroform-acetyl acetate (10:10:1) as a developing agent, unfold, take out, dry, and then use toluene-chloroform-ethyl acetate (10:10:1) as a developing agent, unfold, take out, dry, and spray with 15% nitric acid ethanol solution. Heat at 100°C until the spots are clearly colored and inspect under 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. 【examine】 Moisture content must not exceed 13.0% (General Rule 0832 Second Method). The total ash content shall not exceed 5.0% (General Rule 2302) Germination rate: Take 10g of this product, follow the sampling method for medicinal materials and decoction pieces (General Rules 0211), take two diagonal samples, check the number of germinated grains and the total number of grains, and calculate the germination rate (
