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.

Antimicrobial activity of artemisinin and its precursors.[Reference: WebLink] Current Science, 2000 , 78 (6) :709-713. Artemisinic acid and Arteannuin B are biogenetic precursors of artemisinin, an important antimalarial produced by the herb Artemisia annua. These compounds have been screened for antimicrobial activity against a range of organisms. |

It is readily convertible to qinghaosu in several high yielding steps and has potential antitumor activity. Several approaches to the construction of the cis-decalin backbone have involved the use of electrochemical and metal promoted reductions as well as alkylations. |

Simultaneous densitometric determination of artemisinin, artemisinic acid and arteannuin-B in Artemisia annua using reversed-phase thin layer chromatography.[Pubmed:16342793]
J Sep Sci. 2005 Nov;28(17):2288-92.
A rapid and simple RP-TLC method for simultaneous quantification of pharmacologically important sesquiterpene artemisinin (AM) together with its precursors arteannuin-B (AB) and artemisinic acid (AA) in the inflorescence part of Artemisia annua plant has been developed. The RP-TLC of sesquiterpenes was performed on RP-18 F254 S thin-layer chromatographic plates by developing in mobile phase, containing 0.2% TFA in water/ACN (35:65, v/v). The densitometric determination of AM, AB and AA was carried out after derivatization with anisaldehyde reagent at 426 nm in absorption-reflectance mode.
[Derivatives of arteannuin B with antileukemia activity].[Pubmed:1442049]
Yao Xue Xue Bao. 1992;27(4):317-20.
Arteannuin B (I) was converted to hydroxy lactones (VII, VIII) by a mixture of formic acid and sulfuric acid. Compound VI and Compound VII both showed activity against leukemia P 388 cell in vitro. The rate of growth inhibition were 97.5% and 11.8% for (VI) and 80% and 52.6% for (VII) at the concentration of 10 and 1 micrograms/ml respectively. It seems that the antileukemia activity of 6-membered lactone is higher than that of 5-membered and the methylene group is necessary for the antileukemia activity.
