   • "marginal lands" (貧瘠土地)
   • "domestication" (馴化)
   • "New World" (新大陸/美洲)
   • "food crop" (糧食作物)
   • "dry matter (DM)" (乾物質)
   • "protein" (蛋白質)
   • "dietary fiber" (膳食纖維)
   • "micronutrients" (微量營養素)
   • "vitamins" (維生素)
   • "bioactive compounds" (生物活性化合物)
   • "carotenoids" (類胡蘿蔔素)
   • "phenylpropanoids" (苯丙素類化合物)
   • "animal feed" (動物飼料)
   • "human consumption" (人類食用)
   • "pigments" (色素)
   • "anthocyanins" (花青素)
   • "antioxidant properties" (抗氧化特性)
   • "ẞ-carotene" (β-胡蘿蔔素)
   • "vitamin A deficiency" (維生素A缺乏症)
   • "sweet potato breeding" (番薯育種)
   • "provitamin A" (維生素A原)
2. 逐句翻譯：
   • "Sweet potato (Ipomoea batatas) is a herbaceous perennial vine, which produces storage roots and edible leaves and can grow on marginal lands."
     • 番薯（學名：Ipomoea batatas）是一種草本多年生藤本植物，能生產塊根和可食用葉片，並能在貧瘠土地上生長。
   • "The sweet potato plants have been widely dispersed by humans throughout the world since its domestication in the New World."
     • 自從在新大陸被人類馴化以來，番薯植株已廣泛傳播至世界各地。
   • "Currently, sweet potato is the sixth most important food crop after rice, wheat, potatoes, maize and cassava."
     • 目前，番薯是繼稻米、小麥、馬鈴薯、玉米和木薯之後，全球第六重要的糧食作物。
   • "In 2015, 105 million tonnes of sweet potatoes were produced worldwide and 95% thereof in developing countries with China as the lead producer."
     • 2015 年，全球番薯產量為 1.05 億噸，其中 95% 產於發展中國家，中國是主要生產國。
   • "Both the leaves and storage roots of sweet potato have a high nutritional value for the human diet."
     • 番薯的葉片和塊根都具有很高的營養價值，適合人類食用。
   • "Next to starch which comprises 60% of the dry matter (DM), leaves and storage roots are high in protein, dietary fiber, micronutrients (e.g. iron), vitamins (e.g. vitamin C) as well as bioactive compounds such as carotenoids and phenylpropanoids."
     • 除了占乾物質 (DM) 60% 的澱粉外，番薯的葉片和塊根還富含蛋白質、膳食纖維、微量營養素（例如鐵）、維生素（例如維生素 C）以及類胡蘿蔔素和苯丙素類化合物等生物活性化合物。
