The invention provides a method that effectively stops and restrains the active ingredients of desertliving
cistanche from serious degrading or losing caused by
enzyme catalytic reaction initiated during the
processing,
drying and production technology processes by adopting an improved
drying processing manner of the desertliving
cistanche. The method is characterized in that:
microwave is used for heating and sterilizing
enzyme at high temperature, polar molecules contained in the meat stalk
cell of fresh desertliving
cistanche that is rich in water are led to make
high frequency swing, vibration and friction and
extrusion between the molecules by using a
microwave high frequency electric field so as to lead the temperature inside the
cell of the desertliving cistanche and the surface thereof to raise rapidly, thus generating
thermal effect that has the function of
enzyme sterilization and decoction pieces of the desertliving cistanche is dried rapidly by adopting
microwave drying technology, thus effectively preserving the content of the active ingredients of
phenylethanoid glycosides, etc. that is rich in the meat stalk of the fresh desertliving cistanche and greatly promoting the quality and medical value of the prepared decoction pieces of the desertliving cistanche. Upon analysis and determination, the content of the active ingredients of the
phenylethanoid glycosides, etc. contained in the prepared decoction pieces, which is in the shapes of filiform, elongated flake or granular, of the desertliving cistanche is rich, the content of the main index ingredients of
echinacoside and
verbascoside monomeric compounds of the prepared decoction pieces of the desertliving cistanche, which used for weighing the quality thereof, is up to 13-24.1 percent (being calculated based on dry substance) and the
water content thereof is 1.2-3.8 percent.
