Two spasmolytic diterpene acids, ent-beyer-15-en-19-oic acid and ent-kaur-16-en-19-oic acid, have been isolated from the roots of Viguiera hypargyrea by bioassay-guided fractionation. Beyerenoic acid was also active against Staphylococcus aureus, Enterococcus feacalis and Candida albicans.
通过生物活性导向分离法，从浅灰叶苞菊的根部分离出了两种具有解痉作用的二萜酸，即对映贝壳杉-15-烯-19-酸和对映贝壳杉-16-烯-19-酸。贝叶雷诺酸对金黄色葡萄球菌、粪肠球菌和白色念珠菌也有活性。
