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.
About Packaging 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial.
2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial.
3. Try to avoid loss or contamination during the experiment.
Shipping Condition Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request.

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.
METHODS AND RESULTS:
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.
CONCLUSIONS:
All thirteen compounds significantly inhibited lipopolysaccharide-induced nitric oxide production in BV2 microglial cells at concentrations ranging from 1 microM to 100 microM.

Identification of Chemical Constituents Occurring in Leaves of Alpinia officinarum[Reference: WebLink]

The current study aimed to identify the chemical constituents occurring in the leaves of Alpinia officinarum.
METHODS AND RESULTS:
The collected leaves of A. officinarum were dried in an electric thermostatic drying oven at 40° C overnight. The freshly dried leaves were smashed using a universal high-speed smashing machine and then sieved manually by an 80 mesh. The resulting fine powders and residue were mixed evenly. Twelve flavonoids were chrysin,pinocembrin,tectochrysin,apigenin,galangin,3-methylgalangin,acacetin,kaempferol,kaempferide,quercetin,isorhamnetin and rutin,respectively. Four diarylheptanoids included yakuchinone A,oxyphyllacinol,hexahydrocurcumin and Hannokinol.
CONCLUSIONS:
Sixteen chemicals were identified using LC-MS / MS and some unknown diarylheptanoids need to be identified in the future.
