Difference of Chemical Components in Fruiting Body，Mycelium and Spore Powder of Ganoderma lingzhi

Abstract:

The study aimed to compare the chemical compositions of fruiting body，mycelium and spore powder of Ganoderma lingzhi. Contents of proteins，amino acids，glucose，sugar alcohols，nucleosides and triterpenes were determined，and the HPLC fingerprints of triterpenes were analyzed by similarity. Results indicated that spore powder had the highest protein content of 11.1 % and mycelium possessed the lowest of 7.1 %. Ganoderma lingzhi triterpenoids occurred in fruit body with the highest content and diverse varieties but with low content and less varieties in mycelium and were hardly detected in unbroken spore powder. The content of arabitol was higher than those of other sugar alchols in mycelium，whereas in unbroken spore powder and fruit body mannitol contents were relatively higher. Varieties and contents of nucleosides also differed in three samples. The study demonstrated the difference of chemical components in three portions of Ganoderma lingzhi and indicated that they should be distinguished when applied in health care products.
