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.

A new ent-kaurane from the root extract of Chiococcaalba.[Reference: WebLink]


METHODS AND RESULTS:
A bioassay-guided purification of the methanolic crude extract obtained from the roots of Chiococcaalba (L.) Hitchc. resulted in the isolation of a new, bioactive, metabolite identified as ent-17-hydroxy-16α-kauran-3-one (ent-17-Hydroxykauran-3-one,1). Elucidation of the new structure was based on analyses of the results obtained from various spectroscopic methods (IR, MS, 1H NMR, and 13C NMR) and chemical transformations. The stereochemistry at C16 was assigned by comparing both the proton and carbon chemical shifts of C17 with those reported in the literature.
CONCLUSIONS:
The new kaurane showed weak antimicrobial activity when tested against Staphylococcusaureus.
