Abstract

For utilization of buckwheat as vegetable, rutin and minerals of the leaves at growing stages were investigated. The contents of crude protein and crude fat in seed of nine improved kinds of Korean buckwheat were $16.2{\sim}20.4%$ and $2.2{\sim}2.9%$ respectively. Ash content $(2.4{\sim}4.3%)$ in the improved kinds were higher than those in the native kinds. Content of crude fiber in the improved kinds were lower than those in the native kinds. Suwon 11 (0.12%) and Suwon 5 (0.11%) had high contents of rutin among the improved kinds. The composition of K, Ca, Mg and Fe in the improved kinds were better than that in the native kinds. Vegetable of the improved kinds had higher content of crude protein than the native kinds. Suwon 10 and 11 among vegetables of the improved kinds contained high amount of crude protein. Swon 5 had the highest content of rutin (0.40%) in the improved kinds. Suwon 5 was tested for the changes of rutin content in growing. Rutin content was 0.40% in the first growing stage, whereas 1.32% in the final growing stage. Insoluble materials in 10% HCl was also 69.8% in the first growing stage, whereas 4.68% in the final growing stage. Iron and calcium contents were increased with growing of vegetable.

약성(藥性)을 갖고 여러가지 질병에 유익한 메밀을 채소로 식용하고자 무기성분과 rutin의 함량을 개량종 9품종에서 각각 측정하였다. 9품종의 종실에 대한 일반 성분은 조단백 함량이 $16.2{\sim}20.4%$, 조지방은 $2.2{\sim}2.9%$이었다. 회분 함량은 $2.4{\sim}43%$로 재래종 $(2.4{\sim}2.6%)$에 비해 우수하였으며, 섬유소는 재래종에 비해 $2{\sim}3%$ 낮으며 전체적으로 당질의 함량이 다소 낮았다. 개량중 중 수원 11호와 5호가 각각 0.12%, 0.11%로 높은 rutin 함량을 보였다. 무기물은 회분에 대하여 10% HCI 불용물이 $0.5{\sim}55.32%$ 였으며 K, Ca, Mg 및 Fe 순으로 함유되어 재래종에 비해 우수하였다. 메밀채소의 일반성분은 높은 단백질 함량을 보였으며 수원 10, 11호가 가장 높은 단백질 함량을 보였다. 메밀 채소증 rutin 함량은 $0.20{\sim}0.40%$로 수원 5호가 가장높은 0.40% 함량을 보였다. 메밀함량이 높은 수원 5호의 성장과정중의 rutin함량의 변화는 떡잎시 0.40%, 본잎 $4{\sim}5$장시 1.10%였다. 또한 무기성분의 변화는 10% HCI 불용물이 성장초인 떡잎시 69.8%인 반면 완전 성장시기인 개화시 4.68%였다. Fe와 Ca는 채소성장과 더불어 증가되었다.
