Nine crude drug extracts [Kyokatsu (Notopterygium), Kyonin (apricot kernel), Kujin (Sophora root), Goboshi (Burdock fruit), Goma (sesame), Shokyo (ginger), Shin’i (magnolia flower), Togashi (Benincasa seed), and Bukuryo (Poria sclerotium)] induced the production of trypacidin, which was not produced by culturing in potato dextrose broth without crude drugs.展开更多
