Antrodia camphorata fluid nutrient medium and preparation method thereof
Technical field
The present invention relates to biotechnology, in particular it relates to fluid nutrient medium and preparation method thereof.
Background technology
Mushroom, red antrodia in antrodia (Antrodiacamphorata) also known as cinnamomum kanahirai hay mushroom, camphor tree cave, are subordinate to Basidiomycotina
(Basidiomycotina), Hymenomycetes (Hymenomycetes), Polyporaceae (Polyporaceae), antrodia karst
(Antrodia), it is a kind of rare medicinal fungus for originating in Taiwan.Antrodia camphorata is primary in TaiWan, China mountain area height above sea level 450~2000
The inner wall of the rotten heartwood of cinnamomum kanehirai (Cinnamomea kanehirai) trunk between rice more than distinctive age of tree a century, is platform
The authentic medicinal herbs in gulf are referred to as " Taiwan rarity ", " ruby in the forest of Taiwan ".
Antrodia camphorata contains abundant active material, it is now known that is more than 78 kinds of compounds, including triterpenes
(terpenoids), benzoic acid class (benzenoids), lignanoid (lignans), benzoquinones and its derivative
(benzoquinonederivatives), succinic acid and maleic acid and its derivative (uccinic and maleic
) and polysaccharide body etc. derivatives.Antrodia camphorata is in anti-inflammatory, liver protection, anti-liver cancer and anti-, anti-lung cancer, anti-breast cancer, anti-ovary in recent years
Cancer, inhibitor against colon carcinoma cells, anti-carcinoma of mouth, anti-oxidant, reduction nephritis of systemic lupus erythematousus and anti-platelet aggregation etc. are ground
Study carefully and all show that its future has high development potentiality.Antrodia camphorata is for after drinking or the dispelling effects of alcohol be still drank after a night also highly significant simultaneously.
One of the main active of triterpene substance for Antrodia camphorata, and the most especially, up to 200 kinds or more, be other
What mushroom can not be compared, there is anticancer, liver protection and other effects.Pharmacological research shows that triterpene has anticancer, anti-inflammatory, antiviral and liver protection
Etc. various actives.
Thus, the content for improving activated product triterpenes components in Cinnamomum kanahirai hay camphorata mycelium is to improve Antrodia camphorata drug value
