Determination of Cyanogenic Compounds in Edible Plants by Ion Chromatography
News Dec 10, 2013
Cyanogenic glycosides are HCN-producing phytotoxins; HCN is a powerful and a rapidly acting poison. It is not difficult to find plants containing these compounds in the food supply and/or in medicinal herb collections. The objective of this study was to investigate the distribution of total cyanide in nine genera (Dolichos, Ginkgo, Hordeum, Linum, Phaseolus, Prunus, Phyllostachys, Phytolacca, and Portulaca) of edible plants and the effect of the processing on cyanide concentration. Total cyanide content was measured by ion chromatography following acid hydrolysis and distillation. Kernels of Prunus genus are used medicinally, but they possess the highest level of total cyanide of up to 2259.81 CN-/g dry weight. Trace amounts of cyanogenic compounds were detected in foodstuffs such as mungbeans and bamboo shoots. Currently, except for the WHO guideline for cassava, there is no global standard for the allowed amount of cyanogenic compounds in foodstuffs. However, our data emphasize the need for the guidelines if plants containing cyanogenic glycosidesare to be developed as dietary supplements.

Arrow Poison Potential Male Birth ControlNews
Women have many options for oral contraceptives that are safe, effective and reversible, but despite decades of research, men have none. Now, scientists report a rat study that shows they finally have a good lead for a male birth control pill. It's based on ouabain, a plant extract that African warriors and hunters traditionally used as a heart-stopping poison on their arrows.READ MORE
A Step Toward Ridding Register Receipts of BPANews
Although the U.S and other countries have banned or restricted the use of bisphenol A (BPA) because of environmental and health concerns, it is still used in thermally printed receipts and labels. Now researchers report that they have developed potentially safer polymers that could replace BPA for printed papers.READ MORE
