||Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
Need more advice on solubility, usage and handling? Please email to: email@example.com
||The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

|PREPARATIVE ISOLATION AND PURIFICATION OF ALKALOIDS FROM PICRASMA QUASSIODES (D. DON) BENN. BY HIGH-SPEED COUNTERCURRENT CHROMATOGRAPHY.[Reference: WebLink]|
METHODS AND RESULTS:
By using a two-phase solvent system composed of n-hexane-ethyl acetate-methanol-water (2:2:2:2, v/v/v/v), a high-speed counter-current chromatography technique was successfully used for isolation and purification of three alkaloids from Picrasma quassiodes (D. Don) Benn. for the first time. A total of 22.1 mg of 3-methylcanthin-2,6-dione, 4.9 mg of 4-methoxy-5-hydroxycanthin-6-one and 1.2 mg of 1-methoxycarbonyl-β-carboline were obtained from 100 mg of crude extract of Picrasma quassiodes (D. Don) Benn. in less than 5 hr, with purities of 89.30%, 98.32%, and 98.19%, respectively.
The target compounds were identified by ESI-MS, 1H NMR, and 13C NMR.
