Variation in Polyphenolics and Antioxidant Activity of Traditional Apple Cultivars from West Himalaya, Uttarakhand
No full textApple (Malus × domestica) is largely known for polyphenolic and antioxidant properties; however, systematic investigation in the apple growing in the Indian Himalayan region is not carried out. The present study therefore, attempts to quantify polyphenolics and antioxidant activities in three traditional apple cultivars namely ‘Benoni’, ‘Fanny’ and ‘Rymer’ growing at different locations of Uttarakhand (west Himalaya), India. Results revealed that phenolic (0.94–7.00 mg GAE·g−1 FW), flavonoid (1.02–9.86 mg QE·g−1 FW), flavonol (0.77–6.92 mg CE·g−1 FW), tannin (15.49–37.99 mg TAE·g−1 FW) and antioxidant activity (ABTS, 3.10–67.36; DPPH, 4.99–14.06; FRAP, 4.70–39.21 mmol AAE·kg−1 FW) varied significantly among the cultivars and maximum content was recorded in Rymer fruits of Mukhwa location. Altitude showed significant (P < 0.05) positive relationship with total phenolic (r = 0.895), flavonoid (r = 0.843), flavonol (r = 0.812), ABTS (r = 0.856) and FRAP activity (r = 0.830). Based on the results, it is concluded that among three cultivars, Rymer is one of the most promising sources of polyphenolic content and antioxidant activity and therefore, recommended for mass plantation at suitable locations in Uttarakhand for harnessing maximum potential.

No full textABSTRACTMahonia jaunsarensis Ahrendt is a narrow endemic wild edible fruit-bearing species found in Uttarakhand Himalaya and has the potential of breeding compatibility with economically important Mahonia and Berberis species. Berry fruits of the species were explored for nutritional, phytochemical and antioxidant potential among three sampling locations. Fresh berries appeared a good source of diverse nutrients (carbohydrate 1.07–1.25 g/100 g, protein 0.97–1.13 g/100 g, non-reducing sugar 3.38–3.92 mg/g, and total sugar 9.86–12.87 mg/g); minerals (e.g. sodium 0.56–0.65 mg/100 g and potassium 0.99–1.14 mg/g); and vitamins (ascorbic acid 3.87–4.49 mg/g, thiamine 9.97–11.57 µg/g and carotenoids 1.67–1.94 mg/g). Similarly, phytochemicals (total anthocyanin 18.93–22.12 mg/g, phenolics 1.56–1.80 mg GAE/g, flavonoids 1.49–1.73 mg QE/g, flavonols 4.88–5.66 mg CE/g, and tannins 6.53–7.58 mg TAE/g) and in vitro antioxidant capacity (measured by ABTS assay, DPPH assay, OH· radical scavenging activity and FRAP assays) varied significantly (p < .05) among localities. Various phenolic compounds (particularly, chlorogenic acid 9.93–13.77 mg/g; caffeic acid 0.32–0.65 mg/g; syringic acid 0.30–0.47 mg/g fw) present in the methanolic extract also varied significantly among the localities. Thus, this phytonutrient- and antioxidant-rich genetic resource can be utilized for health-promoting functional foods. Also, the results of the present study indicated that the variation in nutritional, phytochemicals, and antioxidant activity among the locations can be utilized for elite selection, quality control, and breeding programs in the species
