Abstract

Herbaceous peony (Paeonia lactiflora Pall.) is a kind of plant with ornamental, edible and medicinal values, and few studies were concerned to edible aspect of herbaceous peony petals. The aim of this research is to establish edible quality evaluation system of herbaceous peony flowers. Petals of 46 P. lactiflora cultivars at full bloom period were used to determine the content of soluble sugar, organic acid, protein, Vc (Vitamin C), total phenolics, total flavonoids, mineral elements and SOD (superoxide dismutase) activity and screen out evaluation index for edible herbaceous peony. The results showed that flower petals of herbaceous peony contained lots of nutrients and the contents varied with different cultivars. The soluble sugar content was 66.55-177.28 mg/g FW, organic acid 2.19-6.90 mg/g FW, soluble protein 6.53-121.56 mg/g FW, Vc 9.77-30.24 mg/100 g FW, total phenolics 9.41-33.01 mg/g DW, total flavonoids 3.50-17.56 mg/g DW, SOD activity 305.62-520.42 U/g FW, total amino acids 6.43-11.99 g/100 g DW. The average content of Na, Mg, K, Ca, Mn, Fe, Ni, Zn, Mo, Cr were 55.88±14.90 µg/g DW, 1218.22±349.60 µg/g DW, 11252.23±2477.54 µg/g DW, 1975.40±706.58 µg/g DW, 8.30±6.55 µg/g DW, 103.56±182.72 µg/g DW, 10.73±37.94 µg/g DW, 22.80±16.68 µg/g DW, 1.84±5.89 µg/g DW and 17.36±44.89 µg/g DW, respectively. Based on principal component analysis and cluster analysis, we found ‘Dielian Qihua’, ‘Zhushapan’, ‘Xueyuan Honghua’, ‘Wulong Jisheng’, ‘Honglou’, ‘Bingshan’, ‘Hongyan Yushuang’, ‘Zituo Ronghua’, ‘Zifengyu’, ‘Fenlou Dianchun’ had better edible quality. The results will provide some information for the comprehensive utilization of herbaceous peony petals and the breeding of edible herbaceous peony cultivars.
