A quick search ends up with wikipedia giving a brief overview of how it is isolated:. Amygdalin is extracted from almonds or apricot kernels by boiling in ethanol; on evaporation of the solution and the addition of diethyl ether, amygdalin is precipitated as white minute crystals. In case your orgo isn't all that great mine is a little rusty too , what you should read from the above quote is that ethanol is used to oxydize the primary alcohol group to an aldehyde or a carboxylic acid depending on how long you let it boil for making it polar and so non-soluble the diethyl ether an organic solvent which leads it to precipitating out as a white crystal.
Once it precipitates out the easiest way to isolate it is just to use a paper filter, since it should be the only solid present. Suction filtration would be optimal but that's generally not available in high schools. Lastly you could use sublimation to get a really pure final product, but again this isn't normally available in high school labs.
If you're writing a novel I recommend you take the time to read up on it and how it is metabolized within the body.
The more you understand the process the more authentic it'll feel, imo. Best of luck. EDIT: You may want to consider switching to apricot kernels as opposed to apple seeds. The process is effectively the same but it's more realistic, since you'd need a LOT of apple seeds to get a decent amount of cyanide. Also, like I said my orgo is a bit rusty so if someone else could look over this that would be nice.

Apple seeds, and many other fruit seeds or pits, have a strong outer layer resistant to digestive juices.
But if you chew the seeds, amygdalin could be released in the body and produce cyanide. Small amounts can be detoxified by enzymes in your body. However, large amounts can be dangerous. Most apple cores contain around 5 apple seeds.
However, this amount will vary based on the health of the plant. You would need to finely chew and eat about apple seeds, or about 40 apple cores, to receive a fatal dose. Cyanide can harm the heart and brain , and even lead to coma and death.
ATSDR adds that people should avoid eating the seeds of apples, and the pits of fruits that include:. Symptoms of cyanide poisoning can occur quickly. They include shortness of breath and seizures. Both can lead to loss of consciousness. Apple seed oil is a byproduct of juice processing.
The amount of amygdalin found in apple seed oil is generally very small. People use it for its fragrance, to condition hair, and calm skin inflammation. Another study found apple seed oil to be active against bacteria and yeast. Apple seeds contain amygdalin, a substance that releases cyanide into the blood stream when chewed and digested.
However, apple seeds in small amounts do not contain enough cyanide to cause harm. However, it is better to spit out seeds to avoid any potential issues. It's about time we look as young as we feel. The edible parts of these plants contain much lower amounts of these chemicals. Cyanide is contained in cigarette smoke and the combustion products of synthetic materials such as plastics. Combustion products are substances given off when things burn.
In manufacturing, cyanide is used to make paper, textiles, and plastics. It is present in the chemicals used to develop photographs. Cyanide salts are used in metallurgy for electroplating, metal cleaning, and removing gold from its ore.
Cyanide gas is used to exterminate pests and vermin in ships and buildings. If accidentally swallowed, chemicals found in acetonitrile-based products that are used to remove artificial nails can produce cyanide when metabolized by the body.
Reports have indicated that during the Iran-Iraq War in the s, hydrogen cyanide gas may have been used along with other chemical agents against the inhabitants of the Kurdish city of Halabja in northern Iraq.
How you could be exposed to cyanide You could be exposed to cyanide by breathing air, drinking water, eating food, or touching soil that contains cyanide. Cyanide enters water, soil, or air as a result of both natural processes and industrial activities.
When present in air, it is usually in the form of gaseous hydrogen cyanide. Smoking cigarettes is probably one of the major sources of cyanide exposure for people who do not work in cyanide-related industries. How cyanide works The extent of poisoning caused by cyanide depends on the amount of cyanide a person is exposed to, the route of exposure, and the length of time that a person is exposed.
Breathing cyanide gas causes the most harm, but swallowing cyanide can be toxic as well. Cyanide gas is most dangerous in enclosed places where the gas will be trapped.
Cyanide gas evaporates and disperses quickly in open spaces, making it less harmful outdoors. Cyanide gas is less dense than air; so it will rise. Cyanide prevents the cells of the body from using oxygen. When this happens, the cells die. Cyanide is more harmful to the heart and brain than to other organs because the heart and brain use a lot of oxygen. Immediate signs and symptoms of exposure to cyanide People exposed to a small amount of cyanide by breathing it, absorbing it through their skin, or eating foods that contain it may have some or all of the following signs and symptoms within minutes: Dizziness Headache Nausea and vomiting Rapid breathing Rapid heart rate Restlessness Weakness Exposure to a large amount of cyanide by any route may cause these other health effects as well: Convulsions Loss of consciousness Low blood pressure Lung injury Respiratory failure leading to death Slow heart rate Showing these signs and symptoms does not necessarily mean that a person has been exposed to cyanide.
Long-term health effects of exposure to cyanide Survivors of serious cyanide poisoning may develop heart, brain and nerve damage. How you can protect yourself, and what to do if you are exposed to cyanide Since breathing it is likely to be the primary route of exposure to cyanide, leave the area where the cyanide gas was released and get to fresh air.
Quickly moving to an area where fresh air is available is highly effective in reducing exposure to cyanide gas.
If the cyanide gas was released outdoors, move away from the area where it was released.
