Paragraph 0080; 0083, (2017/06/24)
PROBLEM TO BE SOLVED: To provide an anthocyanin synthesis promoter and a chlorophyll degradation promoter that are safe and practicable. SOLUTION: The present invention provides an anthocyanin synthesis promoter and a chlorophyll degradation promoter comprising extract of plant belonging to Hydrocharitaceae Egeria or Elodea. The extract preferably comprises at least one of a compound of formula (I) and a compound of formula (II) as an active compound. SELECTED DRAWING: None COPYRIGHT: (C)2017,JPOandINPIT
Multi-functionalization of gallic acid towards improved synthesis of α- and β-DDB
Alam, Ashraful,Takaguchi, Yutaka,Ito, Hideyuki,Yoshida, Takashi,Tsuboi, Sadao
, p. 1909 - 1918 (2007/10/03)
The synthesis of mono-, di- and trisubstituted gallic acids and their ester with similar or different groups including different acetal and ketals is described. Regioselective bromination on two ortho-positions of methyl gallate, which is very crucial for many organic syntheses, was achieved in high yield and purity. The α- and β-DDB were synthesized in high overall yield and purity from the regioselective bromoderivatives.
