|Biological Activity or Inhibitors:||1. Glutinol acetate shows significant cytotoxic activity against four human cancer cell lines (HL-60, SK-OV-3, A549, and HT-29), with GI(50) in the range of 11.1-17.9microM; it also has anti-inflammatory effect, exhibits moderate inhibitory activity of TNF-alpha secretion in the lipopolysaccharide (LPS)-stimulated murine RAW264.7 macrophage cell line.
|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.|

|Triterpene compounds isolated from Acer mandshuricum and their anti-inflammatory activity.[Pubmed: 20153184 ]|
|In our preliminary screening study on the anti-inflammatory activity, a new triterpene compound, aceranol acetate (1), was isolated along with five known compounds: beta-amyrin acetate (2); Glutinol acetate (3); friedelin (4); glutinol (5); (3beta)-d-glucopyranoside-stigmast-5-en-3-yl (6), from the stems and leaves of Acer mandshuricum. The structure of the new triterpene was determined to be 5alpha,6alpha-epidioxy-5beta,6beta-epoxy-9,13-dimethyl-25,26-dinoroleanan-3beta-ol acetate by spectroscopic studies. Compounds 2-6 were isolated from this plant for the first. Five triterpene compounds (1-5) showed significant cytotoxic activity with GI(50) in the range of 11.1-17.9microM, whereas steroid compound (6) exhibited moderate activity against four human cancer cell lines (HL-60, SK-OV-3, A549, and HT-29). Furthermore, the anti-inflammatory effects of compounds 1-6 in the non-cytotoxic concentrations (1-100nM) were evaluated for the inhibitory activity of TNF-alpha secretion in the lipopolysaccharide (LPS)-stimulated murine RAW264.7 macrophage cell line. Among the compounds tested, compound 2 showed the strongest anti-inflammatory activity with the inhibition rate up to 38.40% at the concentration of 100nM, whereas other five compounds (2-6) exhibited moderate activity.|
