Labdane-type diterpene dialdehyde, pungent principle of myoga, Zingiber mioga Roscoe.
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-diald...
متن کاملMioganal, a novel pungent principle in myoga (Zingiber mioga Roscoe) and a quantitative evaluation of its pungency.
We isolated a novel pungent principle from the flower buds of myoga. Based on an interpretation of the HR-MS, EI-MS, IR, UV, and NMR data, this compound was (8betaH)-14,17-cyclolabda-12,14(17)-diene-15,16-dial (mioganal, 1). We determined the threshold value of mioganal to be 5.6x10(-5) g/ml, which is about eight times greater than that of 8beta(17)-epoxy-12(E)labdene-15,16-dial (miogadial), th...
متن کاملA novel labdane-type trialdehyde from myoga (Zingiber mioga Roscoe) that potently inhibits human platelet aggregation and human 5-lipoxygenase.
We screened myoga extracts for inhibitors of human platelet aggregation and human 5-lipoxygenase. We identified a novel labdane type of diterpene, together with three known diterpenes (miogadial and galanals A and B) from the flower buds of myoga. Spectroscopic data indicated the structure of the new compound to be 12(E)-labdene-15,16,(8beta)17-trial (miogatrial). Miogatrial and miogadial were ...
