    Tenacissoside H Description
    Source: The herbs of Marsdenia tenacissima
    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.

    Determination of tenacissoside H in Marsdeniae tenacissimae by HPLC-ELSD.[Pubmed: 21046734]
    n order to improve the quality standard of Marsdenia tenacissima, a quantitative determination method of Tenacissoside H was developed using high performance liquid chromatography. The method was carried out on a YMC ODS-H80 (4.6 mm x 250 mm, 4 microm) column eluted with a mixture of acetonitrile and water (50:50) as the mobile phase. The flow rate was 0.8 mL x min(-1) and the column temperature was 35 degrees C. An evaporative light scattering detector (ELSD) was used with the temperature of drift tube set at 60 degrees C and the gas flow rate of nitrogen set at 1.5 mL x min(-1). The calibration curve was linear in the range from 0.5625 to 36.00 microg (r = 0.9998). The average recovery and RSD were 99.41% and 1.8%, respectively. The contents of Tenacissoside H in the 11 samples from different habitats varied from 0.201% to 0.862%. The method established in this paper is specific and reliable to control and evaluate the quality of M. tenacissima.
