こんにちは。晨星興産の久保です。さつまいもは食物繊維たっぷりで、便通が良くなるイメージがありますが、さつまいも葉といったらどんな効能を思い浮かべますか?日本人の食事は欧米化してきており、昔は多くの食物繊維やミネラル、植物性タンパク質を日本食で摂取してきました。今回はそんなさつまいも葉についての発表がありましたので、成分及びその効果について調査しました。
さつまいも葉にどんな成分が含まれているのか?
さつまいもの葉の品種はコガネセンガン(生鮮重量100gあたり)になります。各成分は以下のように報告されています。

Influence of Sweet Potato (Ipomoea batatas L.) Leaf Consumption on Rat Lipid Metabolism
The nutrient content of the leaves of sweet potato cultivar Koganesengan was determined to be 35.0 kcal energy, 89.0 g water, 3.9 g protein, 0.8 g fat, 1.0 g carbohydrates, 1.2 g minerals, and 4.1 g dietary fiber/100 g fresh weight. The polyphenol content of the leaves was 11.5 g chlorogenic acid equivalents per 100 g dry weight. Some reports have described that the consumption of dietary fiber and polyphenols is effective in treating dyslipidemia. Therefore, we investigated the influence of sweet potato leaves on lipid metabolism in rats fed a high-fat diet. After 35 days of rearing, the weight gain and adipose tissue weight were lower in the rats fed a high-fat diet supplemented with sweet potato leaves than in those not fed sweet potato leaves. Plasma triglyceride and total cholesterol levels, and liver total cholesterol level were significantly lower in rats fed sweet potato leaves compared to rats fed the high-fat diet alone. These results suggested that the simultaneous intake of sweet potato leaf and the high-fat diet inhibited the excessive accumulation of adipose tissue in rats.
