Dehydronuciferin Introduction

There are dozens of alkaloids in lotus leaves. Numerous alkaloid compounds have been isolated from lotus leaves. According to the structure of the nucleus, lotus leaf alkaloids can be divided into monobenzyl isoquinolines, Dehydroaporphine, and oxidized apophine.

Because the lone electron pair on the nitrogen atom in the molecule can accept protons, although most of them are basic, most of them are weak and cannot be directly dissolved in water. However, they can be dissolved in chloroform, ethanol, and methanol, and other organic solvents.

After the alkaloids react with acids to form salts, they are soluble in water, so the lotus leaf can be extracted with acidic aqueous solutions. When extracting with water, hydrochloric acid can be added to lower the pH of the extract to facilitate the dissolution of alkaloids.
