"Cyanide exists various forms in nature as a salts of Sodium, Potassium and Calcium beside these, hydrogen cyanide or hydrocyanic acid or prussic acid is produced by number of plants of the World flora. In plants Cyanogenesis is a bio-chemical defense mechanism to protect themselves from microbes as well as from herbivore. Amygdalin, Dhurrin, Prunasin Linamarin , Lotaustaralin Cardoispermin etc. are the cyanogenic glycosides present in plants. On hydrolysis these glycosides release hydrogen cyanide. Poisoning of prussic acid is not only to the animals that eat cyanogenic plant but also to the plants themselves. To prevent poisoning themselves the plants store cyanogenic glycosides in a vacuole of the cell and the enzyme that act to produce hydrogen cyanide in a separate compartment. When a cell is damaged the compartments walls are broke and the reaction takes place. In this way hydrocyanic acid is produced by plants only when they needed. In the present study a general survey of angiospermic plants were randomly tested for the presence of HCN by acid hydrolysis method from the Marathwada region of Maharashtra state."
