Abstract:

Buckwheat is an important medicinal and edible minor cereal crop, which has good medicinal and nutritional value. In this paper, 20 buckwheat cultivars were used as trial materials to analyze the differences of nutritional and functional components in seed-case of different buckwheat cultivars. Results showed that there were significant differences in nutritional components of different buckwheat cultivars. The flavonoid content of ‘Zhengning Honghua’, ‘Xuanwei buckwheat’ and ‘miqiao 1’ were the highest among all the cultivars, being 12.8, 12.5 and 10.6 mg/g, respectively, which was 66.2%, 62.3% and 37.7% higher than that of ‘Dingtian 2’. The rutin content of ‘Miqiao’ (3.66 mg/g) was the highest among all cultivars. Also, the lignin content of ‘Miqiao’ was the highest (34.6%), which was 58.1% higher than that of ‘Kuciqiao’ (21.9%), while the change trend of cellulose content was the opposite. The soluble sugar and protein content had no obvious change trend among the cultivars. It can be concluded that the seed-case of ‘Miqiao 1’ has relatively high nutritional value, which is worthy of further promotion in the development of buckwheat seed-case products.
