Abstract

This study compared the nutritional composition and phytochemical properties of turmeric (Curcuma longa) and ginger (Zingiber officinale), two medicinal plants from the Zingiberaceae family. Results showed that ginger had higher crude fiber (5.4%) and carbohydrate (81.3%), supporting digestion and energy, while turmeric contained more protein (6.1%), fat (4.0%), and ash (2.5%), suggesting better mineral composition and longer storage life. Both contained saponins, but turmeric also had tannins and phenols, while ginger contained flavonoids, each contributing to distinct health benefits. The study recommends increased use of both plants in food, pharmaceutical, and industrial applications due to their complementary therapeutic values
