Rhapontisterone B Description
Source: The herbs of Rhaponticum uniflorum (L.) DC.
Solvent: Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, 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).

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.

Structure Identification:
《Journal of Shenyang Pharmaceutical University》 2006-09
Phytosterone constituents from Achyranthese bidentata Bl.[Reference: WebLink]
To isolate and elucidate the phytosterone constituents from Achyranthes bidentata Bl.
METHODS AND RESULTS:
Many kinds of chromatography methods were used to isolate chemical constituents.Physico-chemical characters and spectroscopic analysis (NMR、MS) were employed for structural identification. Five compounds were identified as:Rhapontisterone B(1),stachysterone D(2),rubrosterone(3),β-sitosterol(4),daucosterol(5).
CONCLUSIONS:
Rhapontisterone B and 2 are first isolated from Achyranthes bidentata Bl.
