의성개나리 과피(果皮) 성분(成分)의 항진균작용(抗眞菌作用)에 관한 연구(硏究)(I)

The antifungal studies on the triterpenoids from the pericarp of Forsythia viridissima LINDL. were conducted. The pericarp was obtained from the plant which was cultivated at Eusung, Kyungsang-bukkdo, Korea. Substances A and B were isolated by column fractionation and purified by recrystallization. Antifungal actions of substance A, acetyloleanolic acid, show significant inhibition effect against Trichophyton rubrum, T. mentagrophytes, T. tonsurans, Microsporum nanum, M. canis, and M. cookei. Substance B, viridissimic acid, shows negative effect against Candida albicans and shows lower effects against other test fungi.
