杏仁甙主要存在於苦杏、苦扁桃、桃、油桃(nectarines)、枇杷、李子、蘋果、黑櫻桃等果仁和葉子中,苦杏仁皮中不含苦杏仁甙。
苦杏仁甙由龍膽二糖和苦杏仁睛組成的β-型糖苷,分子式:C20H27NO11,分子量:457.43。
其三水合物為斜方柱狀結晶,熔點200,無水物熔點約有20,[α]:20D-42。1g可溶于12mlH2O,900ml乙醇及11ml乙醇,易溶于沸水。
苦杏仁中苦杏仁甙的含量約3%,是甜杏仁高20~30倍,其中,皮尖部含量略高,皮中不含苦杏仁甙。生杏仁含HCN0.179%,煎煮損耗98%的氫氰酸(HCN,H-C≡N),炒制損耗3-7%的HCN。
苦杏仁中蛋白質包括分解苦杏仁甙的酶,需要在制備過程中使其失去活性,常用焯法,方法是水沸(90-100)后,將苦杏仁(帶皮)放入煎煮,宜掌握時間長短要適宜(一般約5分鐘,太長則丟失原量的34.1%左右,太短則不足以使苦杏仁甙酶失去活性。),取出后,脫皮,烘乾,再次煎煮。
苦杏仁中含脂肪酸50%,為高級潤滑油,可食用,主要是亞油酸(占27%)、油酸(67%)、棕櫚酸(5.2%),具有驅虫、殺菌、潤腸和軟化皮膚角質層等作用,但制備苦杏仁甙時需要除去,出油率為44%。

About Amygdalin Vitamin B17
Amygdalin is the main ingredient of bitter apricot seed extract, also known as laevomandelonitrile or laetrile, is isolated from the seeds of the tree Prunus dulcis, also known as bitter almonds. Since the early 1950s, a modified form of almond extract amygdalin has been promoted under the names laetrile and "Vitamin B17" as a cancer cure. In reality, neither amygdalin nor any derivative such as laetrile is in any sense a vitamin.
Bitter apricot seed extract is the purified form of the compound amygdalin, which is found naturally in fruits and vegetables, particularly in the apricot pits and bitter almonds.Bitter apricot seed extract amygdalin was first isolated in 1830 and was used as an anticancer agent in Russia as early as It is believed that laetrile relieves the pain of cancer. One theory is that cancer cells contain large quantities of the enzyme beta-glucosidase.
This enzyme breaks the amygdalin down and releases cyanide, a toxic chemical that then kills cancer cells.
