二十二酸来自可用于制造辣木油的辣木

二十二酸,又称山嵛酸俞树酸[1],是一种羧酸饱和脂肪酸,分子式为C21H43COOH。就外观而言,它是白色固体,但可能会因杂质而呈黄色。

来源

[编辑]

二十二酸是从辣木Moringa oleifera)种子提取而来的辣木油英语ben oil的主要成分,占比为9%。辣木油的英语名称(ben oil或behen oil)源自波斯历的第十一月Bahman,是这种树的根的收割月。[2]

二十二酸也出现于一些其他油类和含油植物,包括油菜籽(芥花籽)、花生油和花生皮。据估计,一吨花生皮含有5.9 kg的二十二酸。[3]

性质

[编辑]

二十二酸是食用油,在人体内吸收不良。尽管山嵛酸的生物利用度较油酸的低,但它在人体内是增加胆固醇的饱和脂肪酸。[4]

用途

[编辑]

在商业上,二十二酸通常用来对护发素润肤膏给予滋润特效。[3]它还用于润滑剂中,在脱漆剂中可以用来阻滞溶剂挥发。它的酰胺在清洁剂地板抛光剂和无滴蜡烛中用作消泡剂。将山嵛酸还原会得到山嵛醇
