Identification of raw herbs

Character identification

Rhizomes are nodular irregular cylindrical, diameter 1.4-4.2cm, with branches; surface grayish brown, longitudinal wrinkles, cristae are often dense transverse wrinkles, lenticels long horizontal, slightly protruding and pale. Root cylindrical, multi-twisted, diameter 0.3-1.5cm; surface grayish brown or dark brown, wrinkles obvious, thin skin, peeling Department was grayish yellow. Hard, common white cross-section, fibrous. A specific aroma, slightly pungent, slightly bitter, astringent.

Microscopic identification

Powder characteristics; gray to.

1. Bast fibres are long, straight or slightly curved, some wavy, slightly pointed or obtuse at the end, 180-650μm long, 16-54μm in diameter, and 4-18μm in wall thickness. The grooves are thick and dense. Oblique interlaced textures can be seen, and some cells have a thin diaphragm.

2. The diameter of cluster crystals of calcium oxalate is 11-64μm, with large and obtuse edges and corners; some crystal-containing cells are in contact with one another and clusters of crystals are aligned.

3, ray cells tangential longitudinal section view was round or oblong, tangential wall with diagonally staggered or irregular mesh texture.

4, the catheter is textured and ladder pattern. In addition, there are cork cells and a few starch grains.

Physical and chemical identification

Thin layer chromatography: Take this product 2g, add methanol amount, made of 100% (W / V) solution for the test solution. Separately take lilac clove, iso-kaurenoic acid, β-sitosterol, 4-methanol-water (7:3:1, lower clear liquid) to form a 15cm, spray with 10% sulfuric acid deep liquid, and bake it in a thermostatic box at 105°C. 4min color development. In the test solution chromatogram, the same stain was observed only at the corresponding positions of the control products Lilac Cockroach and β-sitosterol.

Steroids

"Steroids are a general term for a large group of derivatives widely distributed in the biological world, which can also be called steroidal or steroidal compounds. Steroid hormones are mainly synthesized and secreted by various parts of the body, and a small part can be synthesized artificially. They play an important auxiliary role in the functional activities of organs, tissues and cells of the body. Steroid hormones mainly include adrenal cortical hormones secreted by the adrenal cortex and gonadal secretion of sex hormones, when taking a large number of steroid hormones, will produce swollen face, nausea and other side effects
