|Source:||The branches of Eysenhardtia platycarpa.|
|Biological Activity or Inhibitors:|
|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.|

|Antihyperglycemic Activity and Chemical Constituents of Eysenhardtia platycarpa[Pubmed: 17190443 ]|
|The methanolic extracts from branches (BEP) and leaves (LEP) of Eysenhardtia platycarpa significantly decreased the blood glucose levels in normal and streptozotocin (STZ)-induced diabetic rats. One new flavone, (1"R)-5,4',1"-trihydroxy-6,7-(3",3"-dimethylchroman)flavone (1), together with the known compounds 5,7-dihydroxy-6-methyl-8-prenylflavanone (3), 5,7-dihydroxy-8-methyl-6-prenylflavanone (4), 5,7-dihydroxy-6-prenylflavanone (5), 5,7-dihydroxy-8-prenylflavanone (6), 3-O-acetyloleanolic acid (7), oleanolic acid, 3beta-Acetoxy-11alpha,12alpha-epoxyoleanan-28,13beta-olide, lupeol, betulinic acid, beta-sitosterol, beta-sitosteryl beta-D-glucopyranoside, beta-sitosteryl palmitate, and 3-O-methyl-myo-inositol were isolated from BEP. Additionally, one new flavanone, (2S)-4'-O-methyl-6-methyl-8-prenylnaringenin (2), as well as the known compounds 3, 4, 6, 4'-O-methyl-8-prenylnaringenin (8), and 5-hydroxy-7-methoxy-8-prenylflavanone (9) were isolated from LEP. 3-O-Acetyloleanolic acid (7), identified as the major constituent of BEP, showed a significant decrease (31 mg/kg of body weight, P < 0.05) in the glucose level of STZ-induced diabetic rats. The obtained results correlate with the traditional use of this species.|
