    A Study on anthocyanins and other biochemical constituents in different plant parts of brinjal (Solanum melongena L.)
    (Punjab Agricultural University, Ludhiana, 2014) Ankita Kumari; Chawla, Neena
    Fifty genotypes of brinjal bearing fruits of different colours (purple, pink, green and white) were evaluated for anthocyanin content in peel, flesh part and whole fruit in fresh tissue, whole fruits were analyzed for dry matter, total soluble sugars, total phenols, ortho-dihydroxy phenols and flavonols in 2012 and 2013. In both years, the peel had high anthocyanin content followed by whole fruit and flesh part. The highest anthocyanin content in peel, flesh and whole fruit was found in SR-312 (purple), SR-308 (green) and SR-303 (purple) respectively. Total phenols content varied in the range of 70.21 to 296.37 mg/100g DW with average value of 125.58 mg/100g in 2012 and in the range of 75.16 to 298.63 mg/100g DW with average value of 120.78 mg/100g in 2013. Highest total phenol content was found in G-415 (green) in 2012 and 2013. G-418 (green) and P-71 (purple) showed ortho-dihydroxy phenols content in the maximum range (80-100 mg/100g). The maximum flavonol content was found in BLEND-11-WR-2 (white). The activity of three enzymes ANS, PAL and TAL were studied in fruit and leaves of fourteen selected genotypes. The activity of ANS in leaves and fruits of green and white colour progressively decreased from 7 days to 21 days while a progressive increase was observed in purple fruits during the same period. The activity of PAL and TAL in both fruit and leaves increased till 14 days and then there was decrease in activity upto 21 days.
