Edible Peony Flowers

This article is an interesting survey of soluble sugars, organic acids, protein, vitamin C, total phenolics, total flavonoids, and mineral elements in the petals of herbaceous peonies in China. The cultivars used are Chinese, and the study shows quite a lot of nutrients in the petals. The scientists determined the optimum harvest time was full bloom, and there was considerable difference among cultivars. Interestingly, the flower color was not a good predictor of the best cultivars. In other words, all pink peonies were not the highest in nutrient values. Several growers have been making a very good, aromatic peony petal jelly, and others add petals to tea. It would be interesting to see how many of these nutrients actually survived the cooking/steeping  process.

Herbaceous peony (Paeonia lactifloraPall.) is a kind of plant with ornamental, edible and medicinal values, and few studies were concernedto edible aspect of herbaceous peony petals. The aim of this research is to establish edible quality evaluation system of herbaceous peonyflowers. Petals of 46P. lactifloracultivars 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
