Ferulic acid has a high content in traditional Chinese medicines such as Ferulic acid Angelica sinensis Chuanxiong Cimicifuga and Suanzaoren One is obtained from the combination of ferulic acid and some small molecules the second is obtained from the plant cell wall and the third is obtained through tissue culture Ferulic acid in plants is often crosslinked with polysaccharides and lignin through ester bonds or selfesterified or etherified to form di ferulic acid Generally alkaline and enzymatic methods are used to break the ester bonds to release ferulic acid and then suitable solvents are used for extraction Item Specifications Results Appearance White or lightyellow acicular crystal Passed Melting point 172 01760C 17261748C Loss on drying 050 016 Residue on ignition 010 004 Heavy metals 10PPM Passed Unspecified impurities 010 Not detected Total 050 Not detected Contents 990 1000 Conclusion Conforms
