Amygdalin (also known as laetrile or erroneously called vitamin B17) is a natural cyanogenic glycoside widely found in the seeds of Rosaceae plants, especially in bitter apricot kernels (bitter almonds). It is the main bioactive component of bitter almond extract.
Basic Information：
Chemical formula: C₂₀H₂₇NO₁₁
Molecular weight: 457.43
CAS No.: 29883-15-6
Appearance: White crystalline powder
Solubility: Soluble in water and hot ethanol
Source：
Amygdalin is mainly extracted from bitter almonds (Prunus armeniaca var. ansu). It also exists in peach kernels, plum seeds, loquat kernels, apple seeds and other stone fruits. The content in bitter almonds is 20–30 times higher than in sweet almonds.
Mechanism & Activity
In the body, amygdalin is hydrolyzed by β‑glucosidase to produce benzaldehyde and trace amounts of hydrocyanic acid (HCN).
In traditional and modern applications, it is used to relieve cough and asthma by mildly calming the respiratory center.
It also shows anti‑inflammatory, analgesic, antioxidant and immunomodulatory effects in pharmacological studies.
Safety Note
Amygdalin itself has low acute toxicity, but excessive oral intake can release toxic cyanide and cause poisoning. It must be used under professional guidance; raw bitter almonds are not safe for direct consumption.
1.Effects of Bitter Almond Extract (Amygdalin)
1. Relieve cough and asthma
It can suppress the respiratory center mildly, helping relieve coughing, especially dry cough and asthma.
2. Analgesic & anti-inflammatory effect
It has a certain pain-relieving and anti-inflammatory action in traditional and modern pharmacological uses.
3. Antioxidant activity
Amygdalin shows antioxidant properties and helps eliminate free radicals.
4. Immune regulation
It may help regulate immune function in experimental studies.
5. Anti-tumor potential (research stage)
It has been studied for anti-tumor effects in laboratory research,
but not clinically proven as a standard cancer treatment.
Important Safety Note
Excessive intake can produce hydrocyanic acid (HCN) and cause poisoning.
Must be used under professional guidance.
Not for uncontrolled long-term or high-dose use.
2.Applications of Bitter Almond Extract (Amygdalin)
