Description: 18-Beta-hydroxy-3-epi-alpha-yohimbine is a natural product from Rauwolfia vomitoria.
18-Beta-hydroxy-3-epi-alpha-yohimbine Description
Source: The roots of Rauwolfia vomitoria
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).

Wherever possible, you should prepare and use solutions on the same day.

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:
Canadian Journal of Chemistry , 1993 , 71 (12) :2201-2203.
Indole alkaloids from [Reference: WebLink]

METHODS AND RESULTS:
Three minor indole alkaloids have been isolated from "hairy roots" of Rauwolfia serpentina Benth.: 3-epi-α-yohimbine (1), 18-Beta-hydroxy-3-epi-alpha-yohimbine (2), and 12-hydroxyajmaline (3). The latter compound (3) is a novel alkaloid.
CONCLUSIONS:
The alkaloid structures have been determined by spectroscopic data.
