    Alpha-pinene Description
    Source: The heartwoods of Pinus armandii Franch
    Biological Activity or Inhibitors: 1. Alpha-pinene inhibits early root growth and causes oxidative damage in root tissue through enhanced generation of ROS, as indicated by increased lipid peroxidation, disruption of membrane integrity and elevated antioxidant enzyme levels.
    2. Alpha-pinene inhibits the nuclear translocation of NF-kappa B induced by LPS in THP-1 cells, and this effect is partly due to the upregulation of I kappa B alpha expression.
    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.

    alpha-Pinene inhibits growth and induces oxidative stress in roots.[Pubmed: 17028297 ]
    Determining the mode of action of allelochemicals is one of the challenging aspects in allelopathic studies. Recently, allelochemicals have been proposed to cause oxidative stress in target tissue and induce an antioxidant mechanism. Alpha-pinene, one of the common monoterpenoids emitted from several aromatic plants including forest trees, is known for its growth-inhibitory activity. However, its mechanism of action remains unexplored. The aim of the present study was to determine the inhibitory effect of Alpha-pinene on root growth and generation of reactive oxygen species, as indicators of oxidative stress and changes in activities of antioxidant enzymes.Alpha-pinene inhibited the radicle growth of all the test species. Exposure of C. occidentalis roots to Alpha-pinene enhanced solute leakage, and increased levels of malondialdehyde, proline and hydrogen peroxide, indicating lipid peroxidation and induction of oxidative stress. Activities of the antioxidant enzymes SOD, CAT, GPX, APX and GR were significantly elevated, thereby indicating the enhanced generation of reactive oxygen species (ROS) upon Alpha-pinene exposure. Increased levels of scavenging enzymes indicates their induction as a secondary defence mechanism in response to Alpha-pinene. CONCLUSIONS: It is concluded that Alpha-pinene inhibits early root growth and causes oxidative damage in root tissue through enhanced generation of ROS, as indicated by increased lipid peroxidation, disruption of membrane integrity and elevated antioxidant enzyme levels.

    Effect of alpha-pinene on nuclear translocation of NF-kappa B in THP-1 cells.[Pubmed: 15066217]
    To study the effects of Alpha-pinene on nuclear translocation of nuclear factor-kappa B (NF-kappa B) and the expression of the inhibitThe majority of FITC-labelled NF-kappa B/p65 was located in the nuclei being stimulated with LPS. Whereas, no such fluorescence was seen in the nuclei of the groups pretreated with Alpha-pinene or control cells. Alpha-pinene pretreatment decreased the NF-kappa B/p65 nuclear translocation in LPS-stimulated THP-1 cells, and this effect was dose-dependent, but there was no reaction in LPS-unstimulated THP-1 cells. Alpha-pinene pretreatment increased I kappa B alpha protein level in cytoplasm, compared with that in LPS-stimulated THP-1 cells. CONCLUSION: In a dose-related fashion, Alpha-pinene inhibits the nuclear translocation of NF-kappa B induced by LPS in THP-1 cells, and this effect is partly due to the upregulation of I kappa B alpha expression.or of NF-kappa B (I kappa B alpha) in human monocyte THP-1 cell line.
