| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

Inhibitory constituents of lipopolysaccharide-induced nitric oxide production in BV2 microglia isolated from Amomum tsao-ko.[Pubmed:18523923]
Planta Med. 2008 Jun;74(8):867-9.
A methanolic extract of the fruits of AMOMUM TSAO-KO (Zingiberaceae) significantly attenuated nitric oxide production in lipopolysaccharide-simulated BV2 microglia. Two new bicyclic nonanes characterized as 6,7-dihydroxy-indan-4-carbaldehyde ( 1) and 6-hydroxy-indan-4-carbaldehyde ( 2) were isolated with the eleven known compounds 6,7-dihydroxy-3,7-dimethyloct-2-enoic acid ( 3), Tsaokoin ( 4), isoTsaokoin ( 5), 8-oxogeraniol ( 6), P-menth-1-ene-5,6-diol ( 7), 3alpha-hydroxycarvotagenone ( 8), tsaokoarylone ( 9), 1,7-bis(4-hydroxy-3-methoxyphenyl)-4,6-heptadien-3one ( 10), (+)-hannokinol ( 11), MESO-hannokinol ( 12) and hannokinin ( 13), from the fruits of A. TSAO-KO using bioactivity-guided fractionation. All thirteen compounds significantly inhibited lipopolysaccharide-induced nitric oxide production in BV2 microglial cells at concentrations ranging from 1 microM to 100 microM.
Isotsaokoin, an antifungal agent from Amomum tsao-ko.[Pubmed:15165158]
J Nat Prod. 2004 May;67(5):889-91.
Bioassay-guided purification of a methanol extract from Amomum tsao-ko led to the isolation of the bicyclic nonane isoTsaokoin (1) as the major active principle, an isomer of the previously reported Tsaokoin (2). The stereochemical relationship of 1 and 2 was investigated by NOE experiments and Mosher ester derivatization. Compound 1 showed antifungal activity against Trycophyton mentagrophytes.
