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.

Biological Activity of Tectoquinone

DescriptionTectoquinone exhibits strong mosquito larvicidal activity.
In vitro

Larvicidal activity of tectoquinone isolated from red heartwood-type Cryptomeria japonica against two mosquito species.[Pubmed: 17804221]

Bioresour Technol. 2008 Jun;99(9):3617-22.


METHODS AND RESULTS:
Mosquito larvicidal activities of methanolic extracts from different plant parts of red heartwood-type Cryptomeria japonica D. Don against the fourth-instar larvae of Aedes aegypti and Aedes albopictus were examined. Results of mosquito larvicidal tests demonstrated that the n-hexane fraction of C. japonica sapwood methanolic extract had an excellent inhibitory effect against the larvae of A. aegypti and A. albopictus and its LC50 values were 2.4 and 3.3 microg/ml, respectively, in 24h. Following the bioactivity-guided fractionation procedure, the active constituent isolated from C. japonica sapwood was characterized as Tectoquinone by spectroscopic analyses. The LC50 values of Tectoquinone against A. aegypti and A. albopictus in 24h were 3.3 and 5.4 microg/ml, respectively. In addition, comparisons of mosquito larvicidal activity of anthraquinone congeners demonstrated that anthraquinone skeleton with a methyl group at C-2 position, such as Tectoquinone, exhibited the strongest mosquito larvicidal activity.
CONCLUSIONS:
Results of this study show that the methanolic extract of C. japonica sapwood may be considered as a potent source and Tectoquinone as a new natural mosquito larvicidal agent.
