Properties and stability


Storage method

This product should be sealed and stored in a dry place away from light.

Synthesis method

This strain is an alkaloid extracted from the gum that precipitates when the all-alkali plant (Rauwolfia genus) of the Apocynaceae family (Rauwolfia) is concentrated in the acid permeate solution, and is produced by chemical synthesis. However, there is currently no synthetic method to produce value, and they are all extracted from Rauwolfia rauwolfia. Take the colloidal substance that precipitates when the acidic percolation liquid of Rauwolfia vulgaris is evaporated and concentrated, add ethanol and glacial acetic acid to obtain an acidic ethanol solution, and then extract it with chloroform to obtain a chloroform solution. It is extracted with acetone in a sexual solution and refined to obtain reserpine. Since this product is highly susceptible to oxidation and deterioration, the entire production process must be conducted away from light. The total yield is about 0.01% for crude drugs and about 0.5% for colloids.
