specific Embodiment approach 1

[0018] Specific embodiment one: present embodiment prepares chelidonate from sugar palm fruit according to the following steps:

[0019] 1. After slicing or crushing the sugar palm fruit, put it into the ethanol solution for soaking, and recover the alcohol soaking solution;

[0020] 2. Remove the ethanol in the alcohol immersion solution, and then perform polyamide column chromatography on the remaining liquid, elute with water, collect the eluate, add organic acid to the eluent, and place it to obtain white needle crystals, which is obtained Chelidonate.

Abstract

The invention provides a method for preparing celandine acid salt from arenga pinnata fruits and relates to a method for preparing a compound from the arenga pinnata fruits. The method for preparing the celandine acid salt from the arenga pinnata fruits includes the steps that 1, the arenga pinnata fruits are placed into an ethyl alcohol solution to be soaked; 2, ethyl alcohol is removed, organic acid is added and stands still, and white needle-shaped crystals are obtained. The method is simple, and a new way is provided for application of the arenga pinnata fruits.

Description

technical field [0001] The present invention relates to a process for the preparation of compounds from sugar palm fruit. Background technique [0002] Chelidonic acid is a white crystalline powder with a molecular formula of C7H4O6 and a melting point of 265°C. Ledronine is a very important organic synthesis intermediate, which is widely used in biochemistry, organic chemistry, medicinal chemistry and so on. In addition, chelidonic acid is also a raw material for the synthesis of many important ligands, for example, it can be used to synthesize terpy, pybox, and many macrocyclic complexes; at the same time, it can also be used as a raw material for cosmetics because of its anti-inflammatory and whitening effects. [0003] The chemical preparation method of chelidonic acid is obtained by reacting diethyl oxalate and acetone, but the reaction conditions are harsh and the process is cumbersome. [0004] Sugar palm (scientific name: Arenga pinnata (Wurmb.) Merr.), a tree of t...
