    Menisdaurin Description
    Source: The herbs of Flueggea virosa
    Biological Activity or Inhibitors:
    Solvent: Pyridine, Methanol, Ethanol, 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.

    Simultaneous quantification of biomarkers bergenin and menisdaurin in the methanol extract of aerial parts of Flueggea virosa by validated HPTLC densitometric method.[Pubmed: 25662964]
    A simple, sensitive high-performance thin-layer chromatography (HPTLC) method was developed for the simultaneous quantification of biomarker bergenin and Menisdaurin in the methanol extracts of aerial parts of Flueggea virosa (FVME). Chromatography was performed on glass-backed silica gel 60F254 HPTLC plates using dichloromethane: methanol as mobile phase. Scanning and quantification was done at UV absorption maxima of 260 nm. The system was found to give compact spot for bergenin and Menisdaurin at Rf = 0.29 ± 0.01 and 0.16 ± 0.01, respectively. The linearity ranges for bergenin and Menisdaurin were found to be the same (100-800 ng/spot) with correlation coefficients (R(2) values) of 0.997 and 0.999, respectively. The limit of detection for bergenin and Menisdaurin was found to be 27 and 36.2 ng/band, respectively, while the limit of quantification was found to be 81 and 108 ng/band, respectively. Intra- and interday precisions (n = 6) for bergenin and Menisdaurin were found to be 1.41-1.71 and 1.65-1.87%, and 1.68-1.89 and 1.75-1.93%, respectively. The percent recoveries were found to be 98.7-99.4 and 99.5-99.9%, respectively, for bergenin and Menisdaurin. The percentage of bergenin and Menisdaurin was found to be 15.25 and 4.22% (w/w), respectively, in FVME. The developed method permitted the simultaneous quantification of bergenin and Menisdaurin and showed good resolution and separation from other constituents of extract; hence, the method can be used to standardize herbal formulations as well as bulk drugs for bergenin and Menisdaurin.
