|Efficient isolation and purification of five products from microbial biotransformation of cinobufagin by high-speed counter-current chromatography.[Pubmed: 20574960]|
METHODS AND RESULTS:
An efficient separation method of using high-speed counter-current chromatography was successfully established to directly purify cytotoxic transformed products of cinobufagin by Cordyceps militaris. The two-phase solvent system composed of n-hexane-ethyl acetate-methanol-water (4:6:3:4, v/v) was used in high-speed counter-current chromatography. A total of 9 mg of 4beta,12alpha-dihydroxyl-cinobufagin (1), 15 mg of 12beta-hydroxyl-cinobufagin (2), 8 mg of 5beta-hydroxyl-cinobufagin (3), 12 mg of Deacetylcinobufagin (4) and 6 mg of 3-keto-cinobufagin (5) were obtained in a one-step separation from 400 mg of the crude extract with purity of 98.7, 97.2, 90.6, 99.1 and 99.4%, respectively, as determined by HPLC. Their chemical structures were identified on the basis of (1)H-NMR and (13)C-NMR technology.
All products (1-5) showed the potent activities against human carcinoma cervicis (Hela) and malignant melanoma (A375) cells in vitro.

||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: firstname.lastname@example.org
||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.
