Hepatotoxic 3-substituted furan terpenes include ipomeamarone and it derivatives, ipomeamaronol and myoporone. Lung toxic compounds are 1, 4-dioxy-1-(3-furyl) pentanes and 4-ipomeanol (most abundant). Hydrocyanic acid (30mg/100g), oxalic acid (1.0%) and phytic acid (8%) and phytosterols are also present in the tubers. Sweet potato also contains scopoletin and some fungicidal and bactericidal substances and enzymes. Stem tips contain indole-3-acetic acid. Sweet potato is capable of forming phytosterols are also present in the tubers (Ghani, 2003). A new furanoterpenoid-dehydroipomeamarone has been isolated from roots infected with Ceratocystis fimbriata. It also contains n-pentacosane, n-heptacosane, n-non-acosane, β-sitosterol, palmitic acid, NaCl, and three unknown compounds A, B and C respectively (Rastogi & Mehrotra, 1993).
