|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.|

|In vitro antidiabetic potential of the fruits of Crataegus pinnatifida.[Pubmed: 25598795]|
|Seven compounds including hyperoside, chlorogenic acid, ursolic acid, oleanolic acid, 3-Epicorosolic acid, β-sitosterol, β-sitosterol glucoside were isolated from these two fractions. 3-Epicorosolic acid showed both potent α-glucosidase and PTP1B inhibitory activities with IC50 values of 30.18 and 4.08 μg/ml respectively. Moreover, kinetic study revealed that 3-Epicorosolic acid showed mixed type inhibition against PTP1B, while it showed uncompetitive inhibition against α-glucosidase. Therefore, these results suggest that the fruits of C. pinnatifida and its constituents have potential antidiabetic activity which might be used as a functional food for the treatment of diabetes and associated complications.|

|Triterpene acids from the leaves of Perilla frutescens and their anti-inflammatory and antitumor-promoting effects.[Pubmed: 14745168]|
|Nine triterpene acids, viz., six of the ursane type, ursolic acid (1), corosolic acid (2), 3-Epicorosolic acid (3), pomolic acid (4), tormentic acid (5) and hyptadienic acid (6), and three of the oleanane type, oleanolic acid (7), augustic acid (8) and 3-epimaslinic acid (9). In addition, an evaluation against the Epstein-Barr virus early antigen (EBV-EA) activation induced by TPA showed five compounds, 1-3, 5 and 9, with a potent inhibitory effect on EBV-EA induction (91-93% inhibition at 1x10(3) mol ratio/TPA).|
