Chemical components: Studies reveal that all parts of the plant, especially the tubers are extremely toxic due to the presence of a highly active alkaloid, Colchicine. The species also contains another toxic alkaloid, Gloriosine (Gooneratne 1966, Angunawela and Fernando 1971). Other compounds such as lumicolchicine, 3-demethyl-N-deformyl-N-deacetylcolchicine, 3-demethylcolchicine, N-formyldeacetylcolchicine have been isolated from the plant (Chulabhorn et al. 1998). Another important alkaloid called gloriosine is also found in tubers (Gooneratne 1966). Colchicine: CAS number: 64-86-8 Molecular formula: C22H25NO6 Molecular weight: 399.44 Structural name: colchicine Toxic effect: A pale yellow to greenish yellow alkaloid Colchicine is mainly responsible for the toxic effect. The toxins in G. superba have an inhibitory action on cellular division resulting in diarrhoea, depressant action on the bone marrow and alopecia. After ingestion of tubers, initial symptoms develop within two to six hours. Intense vomiting, numbness and tingling around the mouth, burning and rawness of the throat, nausea, abdominal pain and bloody diarrhoea leading to dehydration etc. are some of the primary symptoms developed initially in the victim. The other important complications include respiratory depression, shock, hypotension, marked leucopenia, thrombocytopenia, coagulation disorders, oliguria, haematuria, confusion, seizures, coma and ascending polyneuropathy. Alopecia and dermatitis are the late manifestations that develop about one to two weeks after poisoning (Inchem 2004). Clinical and toxicological observations were made by various workers time to time (Gooneratne, 1966; Dunuwille et al. 1968, Angunawela and Fernando 1971, Murray et al. 1983, Kimberly 1983, Saravanapavananthan 1985, Craker and Simson 1986, Wijesundere 1986, Ellenhorn et al. 1996, Inchem 2004). All parts of the plant, especially the tubers, areextremely poisonous.Colchicine, an alkaloid, is responsible for the toxic effect of G.superba . The species also contains another alkaloid 'gloriosine'.The toxic properties of the plant are essentially due to the highly active alkaloid colchicine. Colchicine occurs as pale yellow to greenish yellow, odourless crystals or amorphous scales or powder. It darkens on exposure to light. Other physico-chemical characteristics Melting point is 157°C Solubility in water is about 1/20. It is freely soluble in alcohol and chloroform (Windholz 1983). In addition to colchicine and gloriosine, G. superba also contains other compounds such as 3-desmethyl colchicine, beta-lumicolchicine, N-Formyldesacetyl-colchicine,2-desmethyl colchicine, chelidonic acid and salicylic acid (Duke 1985).
