Technical field
The invention belongs to the field of Chinese medicines, a kind of method being specifically related to machining at low temperature Ganoderma.
Background technology
Ganoderma, also known as Ganoderma lucidum seu Japonicum, Ganoderma, Ganoderma lucidum seu Japonicum, Herba mesonae chinensis, Ganoderma, is Polyporaceae plant Ganoderma lucidum (Leyss. Ex Fr.) Karst. or the sporophore of Ganoderma.
Sweet in the mouth is put down, function replenishing QI and blood, tranquilizing mind, strengthening the spleen and stomach.Begin to be loaded in Shennong's Herbal, be classified as top grade, record by Compendium of Materia Medica:
" Ganoderma property is put down, and bitter in the mouth is nontoxic, and master ties in the heart, the benefit motive, and invigorating middle warmer increases wisdom, do not forgets, and clothes are made light of one's life by commiting suicide always for a long time, and prolong life angle.”
Ganoderma, as having the Chinese tradition valuable ingredient of Chinese medicine of thousands of years medicinal histories, possesses the highest medical value, Ganoderma
Containing polysaccharide, ucleosides, furan derivative, steroid ferment class, alkaloids, albumen in the sporophore, mycelium and the spore that belong to
Matter, polypeptide, amino acids, triterpenes, sesquiterpene, organic germanium, inorganic salt etc..Ganoderan be Ganoderma principle active component it
One, there is antitumor, immunomodulating, blood sugar lowering, antioxidation, blood fat reducing and anti-aging effects.Triterpenes contained by Ganoderma does not descend hundred
Remaining kind, wherein based on tetracyclic triterpenes, the bitterness of Ganoderma is relevant with contained triterpenes.Triterpenes is also effective one-tenth of Ganoderma
/ mono-, human liver cancer cell is had cytotoxicity, also can suppress the release of histamine, there is hepatoprotective effect and have anti-
Allergy effect etc..
