3种酒糟菌糠三萜类成分含量比较

Comparison of triterpenoid content in three distillers' grains-based spent mushroom substrate

对酒糟菌糠中三萜含量进行测定,为酒糟菌糠进一步开发提供依据。以齐墩果酸作为标准样品,用香草醛-高氯酸比色法测定酒糟菌糠中三萜类成分的含量。结果表明茶树菇菌糠(出菇)、茶树菇菌糠(未出菇)、鸡腿菇菌糠(未出菇)的三萜得率分别是0.06%、0.21%、0.13%。三种酒糟菌糠中,茶树菇菌糠(未出菇)的三萜含量最高。

To provide the basis for the further exploration of distiller＇s grains-based distiller＇s grains-based spent mushroom substrate （SMS）, the triter- penoid contents of distiller＇s grains-based SMS were determined. With oleanolic acid as standard, vanillin-perchloric acid colorimetric method was used to determine the triterpenoid content of distiller＇s grains-based SMS. The content of triterpenoid of three kinds of distiller＇s grains-based SMS, spent Agrocybe aegerita substrate （producing mushroom）, spent A. aegerita substrate （no producing mushroom） and spent Coprinus comatus substrate （no producing mushroom） were 0.06%, 0.21% and 0.13%, respectively. The content of triterpenoid of spent A. aegerita substrate （no producing mushroom） is the highest among the three kinds of distiller＇s grains-based SMS.
