Abstract:
A chemical investigation of the fruit juice of Flacourtia inermis furnished five caffeoylquinic acid derivatives: methyl chlorogenate (1), methyl 5-O-caffeoylquinate (2), methyl 4-O-caffeoylquinate (3), n-butyl chlorogenate (4), n-butyl 5-O-caffeoylquinate (5) and a rare phenolic glucoside (rel)-6α-benzoyloxy-1α,2α-dihydroxy-5-oxocyclohex-3-enecarboxylic acid 2-(6-O-benzoyl-β-D-glucopyranosyloxy)-5-hydroxybenzyl ester (6), together with quinic acid (7) and malic acid (8). Compounds 1, 2, 4 and 5 showed strong radical scavenging properties towards the 2,2'-diphenyl-1-picrylhydrazyl radical.
