Preparation for increasing medicinal value of Parasitism in Cistanche decoction pieces

The invention provides a production method, which can enable the content of Phenylethanoid Glycoside combination before and after the processing to keep stable through improving the processing treatment technology of a broomrape decoction piece, wherein, the Phenylethanoid Glycoside combination is the active ingredient abundant in broomrape. Through a high-frequency microwave electrical field, the invention leads a polar molecule in a succulent stem cell of a waterrich fresh broomrape to perform high-frequency swing, vibration, and intermolecular friction and extrusion to cause the inner and surface temperature of a broomrape cell to rise rapidly; the pyrometric effect for inactivating the enzyme activity, so as to effectively block and restrain the degradation loss of the Phenylethanoid Glycoside combination caused by the enzymatic reaction induced by enzyme systems such as hydrolytic ferment, glucoside hydrolase, etc., abundant in a fresh broomrape cell; at the same time, the broomrape decoction piece is dried through the technology for microwave drying or other drying methods. The analysis determination shows that the content of echinacoside and a verbascoside monomer compound which are the main index components for weighing the quality of the broomrape decoction piece in the acquired broomrape decoction piece can reach 13 percent to 24 percent (by dry matters), and the water content is 1.3 percent to 4.1 percent.
