Peach kernel

HCOOCHjCHj. Colourless liquid with the odour of peach-kernels b.p. 54 C, Prepared by boiling ethanol and methanoic acid in the presence of a little sulphuric acid the product is diluted with water and the insoluble ester separated and distilled. Used as a fumigant and larvicide for dried fruits, tobacco and foodstuffs. It is also used in the synthesis of aldehydes.

Colorless gas or liquid with an odor like bitter almond or peach kernels. Odor is detectable at 0.8 ppm, but some individuals are unable to detect odor at all. Used as an industrial fumigant. It is also used in electroplating, mining and in producing synthetic fibers, plastics, and dyes. Industrially, it can be found mixed with a variety of gases including carbon monoxide, cyanogen, and phosphine.

Hydrocyanic Acid, HCN, commonly called prussic acid, occurs in the free condition in certain plants. It is produced as the result of the decomposition of a substance called amygdalin (352), which occurs in the leaves of the cherry and laurel, in bitter almonds, peach kernels, and other substances. It can be formed by exposing a mixture of hydrogen and nitrogen to an electric arc between carbon poles under these conditions about 4.7 per cent of the gases is converted into hydrocyanic acid.

Peach kernel is generally taken as a decoction. If taken directly, in pills or powders, the kernels should be processed by peeling after being boiled in water for a short time. This processing reduces the toxicity (Bensky et al. 2004). The leaf and twig are less toxic than the kernel (Machel and Dorset 1970). 

Overdose (standard dose is a decoction of 4.5-10 g of the kernel) of peach kernel, twig, or leaf may result in poisoning. In children under five, 5 to 10 kernels have caused adverse effects, and 20 kernels have been lethal (Bensky et al. 2004). Symptoms of overdose are similar to cyanide poisoning, including nausea, vomiting, irritation of the gastrointestinal mucosa, headache, dizziness, weakness, blurred vision, increased heart rate, and difficulty breathing (Bensky et al. 2004). 

Texts on traditional Chinese medicine indicate that peach kernel should not be used during pregnancy (Bensky et al. 2004 Chen and Chen 2004). 

No information on the safety of peach kernel during lactation was identified in the scientific or traditional literature. While this review did not identify any concerns for use while nursing, safety has not been conclusively established, and this substance is not recommended for use except under the supervision of an expert qualified in its appropriate use. 

In rats orally administered an aqueous extract (boiled for 3 hours) of peach kernel, inhibition of cholinesterase activity in the brain and plasma was observed. The inhibitory dose (ID50) for brain cholinesterase activity was 2.7 g/kg for plasma cholinesterase activity inhibition, the ID50 was 18.6 g/kg (Suh et al. 2006). 

No estrogenic activity of ethanol extracts of peach kernel was observed in a recombinant yeast system with a human estrogen receptor expression plasmid and a reporter plasmid (Kang et al. 2006 Kim et al. 2008). 

No information on the safety of peach kernel during lactation was identified. 

The LDgQ of an intramuscularly injected aqueous extract of peach kernel in mice is 222 g/kg (Chen and Chen 2004). 

Ethyl formate is a water white, highly volatile and unstable liquid with a pleasant odor resembling peach kernels, it is partly soluble in water and miscible with benzene. It is a powerful solvent For cellulose nitrate and acetate/ yielding solutions of unusual low viscosity which have a tendency to chill. It is on important fumigant and larvicide for the treatment of tobocco/ cereals, dried fruit and similar products. It is used as a chemical intermediate in the manufacture of such medicinals as sulfadiazine, thiamin (Vitamin B]), and perfumes and synthetic flavors.
