Biological Activity
Description: Epimedokoreanin B shows scavenge the DPPH radical activity, it can inhibit the proliferation of MCF-7 and HepG2 in dose-dependant manner. Epimedokoreanin B can significantly inhibit the formation of both N (ε) -(carboxymethyl)lysine (CML) and N (ω) -(carboxymethyl)arginine (CMA), it may prevent clinical complications of diabetes by inhibiting advanced glycation end-products (AGEs).

Two new prenylflavonoids from Epimedii Herba and their inhibitory effects on advanced glycation end-products.[Pubmed: 26758618]
Because inhibitors of advanced glycation end-products (AGEs), for example pyridoxamine, significantly inhibit the development of retinopathy and neuropathy in rats with streptozotocin-induced diabetes, treatment with AGE inhibitors is believed to be a potential strategy for the prevention of lifestyle-related diseases such as diabetic complications.
METHODS AND RESULTS:
In the present study, the MeOH extract of Epimedii Herba (EH; aerial parts of Epimedium spp.) was found to inhibit the formation of N (ε) -(carboxymethyl)lysine (CML) and N (ω) -(carboxymethyl)arginine (CMA) during incubation of collagen-derived gelatin with ribose. Furthermore, compounds with inhibitory effects against CML and CMA formation were isolated from EH. Two new prenylflavonoids (compounds 1 and 2) and two known compounds (3 and 4) were found to significantly inhibit the formation of both CML and CMA; compound 4 (Epimedokoreanin B) had the strongest inhibitory effect of the isolated compounds.
CONCLUSIONS:
These data suggest that Epimedokoreanin B could prevent clinical complications of diabetes by inhibiting AGEs.

Comparison of antioxidative and antitumor activities of six flavonoids from Epimedium koreanum.[Pubmed: 17608228]
To study the antioxidative and antitumor activities of flavonoids isolated from Epimedium koreanum.
METHODS AND RESULTS:
The compounds were separated by column chromatography with silica gel and Sephadex LH-20, and identified by spectral a- nalysis (ESI-MS, 1H-NMR and 13C-NMR) respectively. DPPH radical scavenging assay and MTT assay were used to observe the antioxidative and antitumor abilities. Six compounds were isolated from the the ethyl acetate extract of the aerial part. Their structures were identified as icariin (I), luteolin (II), baohuoside II (III), hyperoside (IV), Epimedokoreanin B (V) and baohuoside I (VI). The results indicated that at concentrations of 3. 125-200 micromol x L(-1), compound I, III and VI had no ability to scavenge the DPPH radical, but the scavenging ability of compounds II, IV and V were stronger than that of Vit C in dose-dependant manner. Compounds I, II, V and VI could inhibit the proliferation of MCF-7 and HepG2 in dose-dependant manner, but compounds III and IV had no effect on the proliferation.
CONCLUSIONS:
The antitumor activity of E. koreanum may be partially related to the antioxidantive activity of flavonoids.

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.

Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

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.
