Selected fruits were also assayed for their specific phenolic
composition through HPLC (Table 4). The amount of caffeic acid
varied from 0.03 to 1.42, p-coumaric acid 0.40 to 3.49, sinapinic
acid 0.09 to 0.78, ferulic acid 0.07 to 1.74, gallic acid 0.55 to
30.41 and protocatechuic acid 0.09 to 2.06 mg/100 g fresh weight.
The amount of gallic acid was found to be dominant among the
genotypes under study and the hydroxycinnamic acid derivatives
were observed to be present in appreciable quantities.
