Abstract
Disclosed is a method for preparing bitterspore powder, and relates to the field of drugs or health care products. The method includes: removing visible impurities fromspores, conducting ice bath and heating extraction, filtering through a microfiltration membrane, sterilizing by drying, and conducting sporoderm disruption to obtain the bitterspore powder. The preparation method effectively improves the content of the bitter substances in thespore powder by removing shriveled spores through multiple times of impurity removal and filtration in combination with the manner of conducting sporoderm disruption after extraction. Taking the totaltriterpenoids in thespores as a representative of the bitter substances, the content of the totaltriterpenoids can reach 5-8%. Meanwhile, the preparation method can also make the content ofpolysaccharides reaching 6-10%.
