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.

Chemical constituents of flowers and fruits of Rabdosia excisa.[Pubmed: 23302530 ]

To study the chemical constituents in the flowers and fruits of Rabdosia excisa.
METHODS AND RESULTS:
The compounds were isolated and purified by silica gel column chromatography and their structures were identified by spectroscopic methods. Sixteen compounds isolated from the flowers and fruits of this plant were identified as: stigm asterol (I), α-amyrin palmitate (II), ursolic acid (III), 2α, 3α, 19-trihydroxy-urs-12-en-28-oic acid (IV), 2α-hydroxyursolic acid (V), maslinic acid (VI), isodonal (VII), Maoyecrystal E (VIII), kamebakaurin (XI), macrocalyxin G (X), epinodosinol (XI), rabdosichuanin C (XII), kamebacetal A (XIII), oridonin (XIV), enmenol-glucoside (XV), and lasiononin (XVI).
CONCLUSIONS:
All the constituents were found in Rabdosia excisa for the first time, except constituents III, IX, XII and XIV.
