Description

Dipsacoside B is a major bioactive saponin, which can be used as a marker.

In Vivo

A liquid chromatography-electrospray ionization-mass spectrometry method has been developed and validated for identification and quantification of four major bioactive saponins in rat plasma after oral administration of extraction of saponins from Flos Lonicerae, i.e., Macranthoidin B, Macranthoidin A, Dipsacoside B, and Macranthoside B. The retention time of Macranthoidin B, Macranthoidin A, Dipsacoside B, Macranthoside B and IS are 10.65, 12.11, 13.81, 23.31 and 5.47 min, respectively[1]. Taking Macranthoidins A, B, Dipsacoside B (saponins), sweroside (iridoids), and luteolin-7-O-d-glucoside (flavonoids) as markers, a method of ultra high performance liquid chromatography with triple quadrupole mass spectrometry is employed to determine their amounts in Lonicerae Flos, Lonicerae Japonicae Flos, and Lonicerae Japonicae Flos preparations[2].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (2.33 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (2.33 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Mice[1]
Sprague-Dawley rats (220-250 g) are used. To calculate the administered dose of Macranthoidin B, Macranthoidin A, Dipsacoside B, and Macranthoside B, their contents in saponins extraction are quantitatively determined. One hundred milligrams of the dry powder is suspended in 100 mL 50% methanol (v/v), ultrasonically extracted for 40 min, and then cooled at room temperature; 50% methanol is added to compensate for the lost weight. Finally, 5 μL of this solution is injected into the HPLC system for analysis after filtration through a 0.45 μm membrane. The contents of Macranthoidin B, Macranthoidin A, Dipsacoside B, and Macranthoside B are found as 36.7, 6.59, 23.3 and 0.506 g/100 g extraction, respectively.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
