Nutritional Compositions of the Leaves of Fuki (Petasites japonicus Miq.), Tsuwabuki (Ligularia tussilaginea Makino), Gobo (Arctium lappa L.) and Gishigishi (Rumex japonicus Houttuyn)

Abstract

Nutritional compositions of the leaves and stalks of Fuki (Petasites japonicus Miq.), Tsuwabuki (Ligularia tussilaginea Makino), Gobo (Arctium lappa L.) and Gishigishi (Rumex japonicus Houttuyn) were analyzed. The following results were obtained. (1) The nutritional compositions were superior in the leaves than in the stalks. (2) The decreasing rates of nutritional compositions by boiling-treatment were less in leaves than in stalks. (3) The nutritional compositions of Gishigishi which is not edible in Japan were superior to others.
