使用一些细菌、酵母和霉菌菌株研究了从姜 (Zingiber mioga Roscoe) 植物花蕾中分离出的三种二萜二醛（miogadial、galanal A 和 galanal B）的抗菌活性。在这三种化合物中，miogadial 对革兰氏阳性细菌和酵母菌表现出比其他化合物更高的抗菌活性。半乳糖醛 A 和 B 还可以作为针对革兰氏阳性细菌和酵母菌的抗菌剂。花蕾中miogadial的含量远高于叶片中的含量，而叶片和根茎中的galanal A和B含量较高。
The antimicrobial activities of the three diterpene dialdehydes, miogadial, galanal A and galanal B, isolated from flower buds of the myoga (Zingiber mioga Roscoe) plant were investigated with some strains of bacteria, yeasts and molds. Among the three compounds, miogadial exhibited relatively greater antimicrobial activity than the others against Gram-positive bacteria and yeasts. Galanals A and B also behaved as antimicrobial agents against Gram-positive bacteria and yeasts. The content of miogadial in the flower buds was much higher than that in the leaves, whereas galanals A and B were contained at high levels in the leaves and rhizomes.
