Authenticity authentication Because of the nourishing effect of dodder seed, the pharmaceutical and clinical needs are large, and its production is low, resulting in an imbalance of supply and demand. Therefore, dodder seed is one of the varieties with the highest unqualified sampling rate in each medicinal material market. Confusion, fakes emerge one after another. Common adulteration phenomenon: 1. Use the seeds of the Amaranthaceae in the Chihoho Valley (alias grain pods), which are small in size and have a thin middle drum, shaped like a flying saucer. Yellow-white or red-black, 1,000 grams weight about 0.5 grams. Incorporation by staining. 2. The raw materials of counterfeit goods are also made of fine mud sand and turned into starch, glue, fine mud sand, other fine powder of plants, and pigment processing. Comparing with the counterfeit products made of all-terrain sand, the counterfeit weight of this counterfeit product is even more deceptive due to the number of particles, color, and feel of the counterfeit product. The phenomenon of adding a small amount of genuine dodder from counterfeit products occurs from time to time. 3. Dodder seed: adulterants mixed dodder with a small suis. Identification: Observed with a magnifying glass, there are navel-like depressions on each dodder, and there are no fake ones. When boiled with water, sticking of silkworms was observed. Physical and chemical identification of dodder genuine and counterfeit products: take dodder and false products lg, set the test tube, add boiling water soak, dodder surface sticky, light brown water solution, heat cook until the seed coat rupture, can reveal yellow-white roll The embryo is shaped like spinning. Counterfeit water immersion light brown to dark brown yellow or light green (depending on the color of the pigment used). The particles expand and become pale, light green. But not broken (different from silt counterfeit) long bubble heating without yellow-white curled embryos exposed. Authentic observation surface under the magnifying glass has fine dark dots, a dimpled linear umbilicus at one end, extruded into a sheet with a hard object, and cannot be crushed.
