Antimicrobial activities of diterpene dialdehydes, constituents from myoga (Zingiber mioga Roscoe), and their quantitative analysis. Bioscience, biotechnology, and biochemistry, 2004, Volume: 68, Issue:7 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.

Labdane-type diterpene dialdehyde, pungent principle of myoga, Zingiber mioga Roscoe. Bioscience, biotechnology, and biochemistry, 2002, Volume: 66, Issue:12 The pungent principle of myoga (Zingiber mioga Roscoe) was identified as (E)-8beta(17)-epoxylabd-12-ene-15,16-dial (miogadial) on the basis of its physical and spectroscopic properties (MS, NMR, IR, and UV). Galanal A and B, isolated as well as miogadial, had no hot taste. Reduced miogadial also was tasteless. The pungency of miogadial depended on the presence of alphabeta-unsaturated-1,4-dialdehyde group. Topics: Diterpenes; Humans; Molecular Structure; Taste; Zingiberaceae	2002
