Identification
Appraisal processing:
[Process Method] Achyranthes:
Remove impurities, wash, run through, remove residual reeds, cut into sections, and dry.
This product is a cylindrical section. The outer epidermis is yellow or light brown with fine longitudinal wrinkles and long horizontal lenticels. Hard and brittle, easy to break, wet and soft. The section is flat, light brown or brown, slightly keratinous and oily. The center of the vascular bundle is large and yellowish-white, with most of the yellow-white spotted vascular bundles scattered around it, and is arranged intermittently in 2 to 4 rounds. Gas slightly, slightly sweet and slightly bitter.
1. "Leigong Artillery Paradox": Where the Achyranthes, go to the head and dust, dip in a natural juice with Huang Jing overnight, scoop out, fine, dry, use it.
2. "Outline": Achyranthes, this wine can only be immersed in medicine. If you want to descend, you will use it, nourishing it, baking it, or mixing it with steam.
Identification of raw medicinal materials The identities of the identification roots are elongated and cylindrical, some are slightly curved, the upper ends are slightly thicker, and the lower ends are finer, 15-50cm long and 0.4-1cm in diameter. The surface is yellow or light brown, with fine longitudinal wrinkles, small transverse lenticels, and sparse fine lines. Hard and brittle, easy to break, flat section, yellowish-brown, slightly keratinous, central vascular bundle larger, yellow-white, most of its outer scattered
The vascular bundles are arranged in 2-4 turns. Gas slightly, taste sweet, astringent.
It is better to use long, thin skin, fat, yellow and white.
Microscopic identification of the root cross-section: the cork layer is a series of cells, the cortex is narrow. The pillars account for most of the roots, and the majority of the vascular bundles are arranged in a discontinuous array of 2-4-8 rounds. The outermost vascular bundles are smaller.
Formation of several connections into a ring; inward several rounds of vascular bundles, wide ray narrow width; xylem catheter, wood fiber and wood parenchyma cells, the root of the secondary xylem integrated 2-3 fork, newborn Xylem 2-3 prototype. Parenchyma cells contain calcium oxalate crystals.
Physical and chemical identification
(1) Foam Test Take a small amount of this product powder, add 10 times the amount of water and shake it enough to produce a lot of foam, and it will last for a long time. (check soap type)
(2) Hemolysis test Take 1% fresh rabbit blood diluted in physiological saline (1 ml) and add a certain amount of physiological saline solution (1:10) along the wall of the product. Hemolysis occurs rapidly. (Check saponins)
(3) Thin-layer chromatography to take 2g of this product powder, add ethanol 20ml, reflux extraction 40min, and let stand. Take 10ml of supernatant, add 1ml of hydrochloric acid, reflux for 1h, concentrate to about 5ml, add 10ml of water, extract with petroleum ether (60-90°C) 20ml, extract dry, add 2ml of ethanol and dissolve as residue . Separately, oleanolic acid plus ethanol was made into a solution containing 1 mg per 1 ml as a reference solution. Draw 10-20 μl of the test solution and 10 μl of the control solution, and place them on the same silica gel G plate, expand with a solution of chloroform-methanol (40:1), and take out to dry, spray with phosphomolybdic acid test solution, 110 °C for about 10min. spot.
Product specifications

Morphology: It is a kind of perennial herb of the genus Achyranthes, 20-120cm tall. The root is slender, 3-5mm in diameter and yellowish brown. Stems are 4-angled, pilose, branch nodes slightly swollen, branching opposite. Leaves opposite; petiole long 5-15mm; leaf blade papery, broadly ovate-obovate or elliptic-oblong, 1.5-7cm long, 0.4-4cm wide, Zhu Duan blunt, with apex, base cuneate or rounded, entire Or wavy edges, densely covered with coarse hair on both sides. Spikes terminal, erect, long 10-30cm, reflexed after anthesis; total peduncles angular, stout, hard, dense white volt or pubescence; flowers long 3-4mm, sparsely; bracts lanceolate, 3-4mm long, apex long acuminate; small bracts spiny, 2.5-4.5mm long, hard, shiny, often with purple, each side of the base has a thin film wing, 1.5-2mm long, all lines, all stickers Born in thorns, but easy to separate; tepals lanceolate, 3.5-5mm long, acuminate, hardened and acute after flowering, with 1 vein; stamens 2.5-3.5mm long; staminodes apex truncate or Fine scalloped, with branching fringed long hair. The fruit is oval, 2.5-3mm long. Seeds ovate, not compressed, ca. 2 mm, brown. Flowering from June to August and fruiting from October. The difference is: the leaves of this mutant are oval-shaped, 2-9cm long, 1-4cm wide, acutely pointed at the tip, wedge-shaped at the base, wavy at the edge, pilose on both sides, more hairy below, and reddish brown when dry.
The dried roots are long, cylindrical, slightly curved, much branched, up to 75 cm in length and about 0.4-1.5 cm in diameter. The appearance of gray brown, there are significant wrinkles and stripes, not easy to break, cross-section fiber, brown. Odorless, sweet taste. To hypertrophy, oily, brown gray appearance is better.
chemical composition
The root contains saponin and contains ecdysterone and achyrantone.
It can be used for surgical operations, patient treatment; epidemic prevention and inspection in public places; disinfection in virus-contaminated areas; and can also be widely used in military, medical, chemical, environmental protection, transportation, epidemic prevention and other field
By setting a protective collar, the neck of the operator can be kept warm and protected. The provision of a hand guard is helpful for the surgical staff to temporarily place their hands in the hand guard while waiting during the operation, which plays a protective role and is more in line with the principles of aseptic operation and occupational protection.
By setting the shrinking cuffs, it is beneficial to make the cuffs fit the wrists, prevent the cuffs from loosening, and prevent the gloves from slipping off during the operation and the operator's hands are exposed to the gloves.
The design of the new humanized protective surgical gown has been improved in the key areas of the gown. The forearm and chest area are double-thickened, and there are handguards in front of the chest and abdomen. By arranging reinforcing sheets (double-layer structure) in key areas, it is beneficial to improve the water-permeability of surgical gowns and improve safety.
