Fig. 1. Sampling region of fresh potato for PGA content during storage.
Fig. 2. HPLC chromatograms of α-chaconine and α-solanine in a standard mixture (A), and PGA extracted from the peel of HR (B). Conditions: column, Inertsil NH2 (5 μm, 4.0×250 mm); mobile phase, acetonitrile/ 20 mM KH2PO4 (80:20, v/v); wave length, 208 nm; column temperature, 20°C; flow rate, 0.7 mL/min; injection volume, 20 μL.
Fig. 3. Content of α-chaconine (A), α-solanine (B), and total PGA (C) in six potato cultivars by tuber parts and different sizes. Vertical bars show standard error of mean of three replicates. Bars with different letters show significant difference (p < 0.05) as determined by Duncan’s Multiple Range Test. Cultivars: SP, Superior; AT, Atlantic; HR, Haryoung; GU, Goun; HY, Hongyoung; JY, Jayoung. Tuber size: L, Large; M, Medium; S, Small; A, Average.
Fig. 4. Changes of the contents of α-chaconine (A), α-solanine (B), and total PGA (C) in six potato cultivars during storage. Vertical bars show standard error of mean of three replicates. Cultivars: SP, Superior; AT, Atlantic; HR, Haryoung; GU, Goun; HY, Hongyoung; JY, Jayoung.
