Application


  • Nematocidal alkaloids from the roots of Stemona mairei: This study explores the use of Dragendorff reagent for the identification of nematocidal alkaloids, demonstrating its critical role in the pharmacological profiling and characterization of natural products (Shi et al., 2023).

  • Rapid Detection and Determination of Scopolamine in Black Henbane: Leveraging Dragendorff reagent, this research developed a novel nanosensor for detecting scopolamine, an important application in pharmaceutical analysis and toxicology (Mousavizadeh et al., 2022).

  • Proximate analysis and multi spectrometric analysis of Strychnos nux-vomica nuts: The use of Dragendorff reagent in the multi-spectrometric analysis highlights its versatility in chemical synthesis and compound identification, providing essential insights for medicinal chemistry (Ramachandran et al., 2022).

  • TLC-MS identification of alkaloids in Leonuri Herba and Leonuri Fructus: This study used Dragendorff reagent to optimize a universal derivatization method, enhancing the detection and analysis of key pharmaceutical compounds in traditional medicine (Zhang et al., 2021).

  • Densitometric TLC analysis for control of tropane and steroidal alkaloids in Lycium barbarum: Demonstrates the application of Dragendorff reagent in food chemistry for ensuring the safety and efficacy of herbal supplements through the precise detection of alkaloids (Kokotkiewicz et al., 2017).

Other Notes

This non-aqueous Thiess, Reuther and Vagujfalvi variant of the reagent is used to detect alkaloids and other nitrogen compounds in TLC[1][2][3]

The urinary metabolites of berberine, an isoquinoline alkaloid isolated from several Chinese herbal medicines, were investigated in rats and humans. Using macroporous adsorption resin chromatography, open octadecyl silane column chromatography and preparative high-performance liquid chromatography, we isolated seven metabolites (HM1-HM7)

Questions

1–2 of 2 Questions  
  1. 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

  2. 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/449/386/product-dating-information-mk.pdf
