Trait identification
The tuberous root is spindle-shaped or lumpy, generally slightly curved. The length is 5- 15cm and the diameter is 4- 10cm. The surface is reddish brown or reddish brown, uneven, with irregular longitudinal grooves and dense wrinkles, and horizontal lenticels and fine root marks.
Hard, not easy to break. The cut surface is yellowish brown or reddish brown, powdery, and the skin has round-like abnormal vascular bundles arranged in a ring, forming a brocade pattern, with a large central wood and some wood hearts. Slight gas, slightly bitter and sweet taste. It is better to be solid in weight and quality and full of powder.
Microscopic identification
Cross section of root tuber: cork layer is a series of cells, full of reddish-brown substances, and lenticels can be observed. The phloem is wide, scattered with heteromorphic vascular bundles, that is, composite vascular bundles, and the other is a single vascular bundle, both of which are external tough. The cambium is annular, with few xylem vessels, tracheids and a few wood fibers around it. The center of root tuber is primary xylem. The parenchyma cells contain starch granules and calcium oxalate clusters.
Powder characteristics
Brown. ① There are many starch granules, with a single granule in the shape of spherical, helmet-shaped or triangular cone, with a diameter of 4-50μm, and the umbilical point is herringbone, star-shaped, arc-shaped or punctate, with no obvious layering. The diameter of compound grains is 6-5 1μm, which is composed of 2-9 fractions. ② There are many cluster crystals of calcium oxalate with a diameter of about 80μm, and occasionally cluster crystals are combined with larger square-like crystals. ③ The diameter of the duct with marginal holes17-178 μ m; There are also tiny reticulated ducts.
Physical and chemical identification
1. Take about 0. 1g of this product powder, add sodium hydroxide solution (1- 10) 10ml, boil for 3min, cool and filter. Take the filtrate, add hydrochloric acid to make it acidic, add the same amount of ether, shake it, and the ether layer should be yellow. Take 4ml of ether layer, add 2ml of ammonia test solution, shake it, and the ammonia liquid layer turns red. (Check anthraquinone compound)
2. Take about 0.2g of this product powder, add 5ml of ethanol, boil in a water bath for 3min, shake constantly, filter while it is hot, and let it cool. Take 2 drops of the filtrate, put it in an evaporating dish and evaporate it to dryness. When it is hot, add chloroform saturated solution of antimony trichloride 1 drop, and it will turn purple. (check sterols)
3. TLC: Take 5g(40 meshes) of Polygonum multiflorum Thunb powder, reflux extract with 95% ethanol, and recover ethanol to make1.5:1extract for sampling. In addition, emodin and physcion were used as control substances. Dotted on a silica gel G-CMC (silica gel G300 mesh or more) plate, and spread with chloroform-methanol (80: 20) with a spread of 10cm. Take it out and air dry, and under visible light, in the chromatogram of the test sample, the same color spot appears at the position corresponding to the chromatogram of the control sample; Show the same fluorescent spots under ultraviolet light.
