Catechin pentaacetate Description
||The bark of Taxus yunnanensis
||Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
||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.

* Note: If you are in the process of experiment, it's need to make the dilution ratios of the samples. The dilution data of the sheet for your reference. Normally, it's can get a better solubility within lower of Concentrations.
Catechin pentaacetate References Information
|Process for the production of a compound (&plus ) catechin penta acetate useful as a precursor for the production of (&plus ) catechin[Reference: WebLink]|
|This invention relates to a process for the production of a compound (+) Catechin pentaacetate of formula I from Taxus wallichiana tissue cultures which comprises : (a) inoculation of explants on different media compositions supplemented with combinations of auxins (1-5 mg/l) and cytokinins (0.1-1.0 mg/l); (b) incubation of the cultures under continuous light or dark conditions for 4-6 weeks for callus cultures followed by subculturing at 4-6 weeks intervals; (c) harvesting of the calli at different growth phases ranging from 12-36 months; (d) extraction of fresh pulverized calli with polar solvents at room temperature; (e) evaporating the solvent to give a residue; and partitioning of the residue between water and chlorinated solvents and evaporating the solvent to a semisolid mass; (f) subjecting the resultant mass to column chromatography over suitable adsorbent and (g) eluting with organic solvent/mixtures of organic solvents to get (+) Catechin pentaacetate.
