|Biological Activity or Inhibitors:|| 1. Triptocalline A shows an inhibitory effect on rat lens aldose reductase.
|Solvent:||Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.|
|Storage:||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.

|After receiving:||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.|

|Structures of new friedelane-type triterpenes and eudesmane-type sesquiterpene and aldose reductase inhibitors from Salacia chinensis.[Pubmed: 14510595 ]|
|Three new friedelane-type triterpenes named salasones A (1), B (2), and C (3), a new norfriedelane-type triterpene, salaquinone A (4), and a new acylated eudesmane-type sesquiterpene, salasol A (5), were isolated from the 80% aqueous methanolic extract of the stems of Salacia chinensis collected in Thailand. Their stereostructures were elucidated on the basis of chemical and physicochemical evidence. In addition, six constituents, 3beta,22beta-dihydroxyolean-12-en-29-oic acid, tingenone, tingenine B, regeol A, Triptocalline A, and mangiferin, were found to show an inhibitory effect on rat lens aldose reductase.|
