General description

Kaempferol is a polyphenolic antioxidant abundantly present in vegetables and fruits.[1] It has a diphenylpropane structure. In many plants, it is present as a glycosidic form namely, kaempferol-3-O-glucoside.[2]

Application

Kaempferol has been used:
  • to test its effect on osteoblast proliferation, migration, and differentiation in mouse pre-osteoblast cell line (MC3T3-E1 cells)[3]
  • as an antioxidant and a hepatoprotective agent against zearalenone (ZEA)-induced oxidative stress and apoptosis in HEPG2 cells[4]
  • as a neuroprotective agent against cadmium chloride (CdCl2) induced hippocampal damage and memory deficits in rats
  • as an anti-inflammatory agent, together with apigenin, for stem-cell therapy on knee osteoarthritic male rats[5]

Chromogenic reagent for antimony in the low ppm range and for gallium and indium in the sub-ppm range.

Biochem/physiol Actions

Kaempferol is hydrophobic in nature due to its diphenylpropane group.[2] It exerts anti-inflammatory actions along with their antioxidant properties and modulates pro-inflammatory enzyme activities.[2] Kaempferol acts as a chemopreventive agent by exerting protective effects on cell viability.[1] It modulates several key elements of cellular signal transduction pathways linked to apoptosis, angiogenesis, metastasis, and inflammation.[1]
Potent inhibitor of osteoclastic bone resorption. The effect is believed to be attributable to both the antioxidant and estrogenic activities of kaempferol.

Questions

1–2 of 2 Questions  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-mk.pdf

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
