全球約有2000種植物含有物質可揮發成為山埃氣體，南北杏就是其中的兩種。978Please respect copyright.ＰＥＮＡＮＡcz9BykLVrl

南杏仁又稱之為甜杏仁(sweet apricot kernel)，而北杏仁則為苦杏仁(bitter apricot kernel)。978Please respect copyright.ＰＥＮＡＮＡA8G3NWLxVU

相對上，南杏仁的毒性比北杏仁遠之為低。978Please respect copyright.ＰＥＮＡＮＡFsBmNRyG05

（圖2）南北杏內含化學物質扁桃苷(Amygdalin)，以及能夠分解扁桃苷並釋放出山埃的酵素。978Please respect copyright.ＰＥＮＡＮＡkOpzkTGxpn

在正常情況下，扁桃苷及能夠分解它的酵素就像是牛郎及織女一樣被分隔開兩地。978Please respect copyright.ＰＥＮＡＮＡIBMhZhv24O
而當我們嘴嚼南北杏的時候，其內部結構便會有所破壞，酵素亦得以與扁桃苷接觸，並釋發出對人體有害的山埃物質;978Please respect copyright.ＰＥＮＡＮＡTqRQFyzVca
與此同時，胃酸及腸道細菌亦有能力將扁桃苷分解成為山埃。978Please respect copyright.ＰＥＮＡＮＡE8CXdF5Mkh

（圖3）每克北杏仁大概含有26 ± 14 mg扁桃苷，而每克南杏仁則大概含有0.16 ± 0.09 mg扁桃苷。978Please respect copyright.ＰＥＮＡＮＡnPzKT07glK

基於北杏所含的扁桃苷比南杏為高，因此相對上北杏在體內釋放出的山埃亦會較多。978Please respect copyright.ＰＥＮＡＮＡx5vD5SwTWw
山埃能夠抑制細胞產生能源的機制，對於經常性需要使用能源的心臟及大腦尤其傷害為深。978Please respect copyright.ＰＥＮＡＮＡDdqE33UM1s

口服山埃致命量為0.56mg/體重kg，以一個重80 kg的暴力警察為例，他口服44.8mg山埃後便會中毒致死。978Please respect copyright.ＰＥＮＡＮＡ9xo70QUVWf
978Please respect copyright.ＰＥＮＡＮＡhP4MCl1GuE
每457克的扁桃苷約可釋出26克的山埃，以北杏每克含有40mg扁桃苷作計算的話，80 kg的暴力警察攝取多少克北杏便會中毒身亡呢?978Please respect copyright.ＰＥＮＡＮＡJEErtBStor
