|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.

|Analgesic and anti-inflammatory activities of 11-O-galloylbergenin.[Pubmed: 20603209 ]|
|Current study was designed to explore the analgesic and anti-inflammatory effects of a constituent isolated from Mallotus philippinensis, in order to validate its folk use. MATERIALS AND METHODS:11-O-Galloylbergenin was isolated from ethanolic extract of Mallotus philippinensis. Analgesic and anti-inflammatory activities of the test compound were assessed using formalin test and carrageenan-induced paw edema models.RESULTS:11-O-Galloylbergenin showed significant analgesic activity at doses of 20 and 40 mg/kg against formalin test in rats. Similarly, 11-O-Galloylbergenin exhibited significant anti-inflammatory activity in carrageenan-induced paw edema model at doses of 10, 20 and 30 mg/kg.|

|Comparative antioxidant and antiplasmodial activities of 11-O-galloylbergenin and bergenin isolated from Bergenia ligulata.[Pubmed: 24862054]|
|In the present study, the antioxidant and antiplasmodial activities of bergenin was compared with its natural derivative 11-O-Galloylbergenin for the first time. Both compounds were isolated from Bergenia ligulata. 11-O-Galloylbergenin was found to be very active in in-vitro antioxidant assay as compared to bergenin, which was found to be almost inactive. The EC50 values of 11-O-Galloylbergenin were 7.45±0.2 μg/mL and 5.39±0.28 μg/mL in DPPH antioxidant assay and reducing power assay respectively, while IC50 value for antiplasmodial assay of both compounds were less than 2.5 μM. Interestingly, in the total antioxidant phosphomolybdate assay, 11-O-Galloylbergenin was found more potent (CAHT: 940.04±115.30) as compared to α-tocopherol (CAHT: 552.4±27.91).|

|Structure activity relationship of bergenin, p-hydroxybenzoyl bergenin, 11-O-galloylbergenin as potent antioxidant and urease inhibitor isolated from Bergenia ligulata.[Pubmed: 25674661]|
|Ethanol extract of the aerial parts of Bergenia ligulata was subjected to solvent-solvent separation followed by various chromatographic techniques that lead to isolation of bergenine (1), p-hydroxybenzoyl bergenin (2), 11-O-Galloylbergenin (3) and methyl gallate (4) as major constituents. Ethyl acetate fraction showed a dose-dependent urease inhibitory pattern with IC50 value of 54μg/mL. Structures of compounds 1 and 3 were established by XRD and 2, 4 by NMR. All these compounds were subjected to DPPH scavenging activity, reducing power assay and urease inhibitory activity. The EC50 7.45 ± 0.2 μg/mL and 5.39 ± 0.28 μg/mL values in terms of antioxidant and reducing power, respectively, were less for 3. Compounds 1-3 showed moderate to significant urease inhibitory potential with IC50 57.1 ± 0.7, IC50 48.4 ± 0.3 and 38.6 ± 1.5. Antioxidant activities and urease inhibitory potential were investigated and compound 3 was found to be the most active.|
