Constituents:

Prunus amygdalus Linn. oil contains triglycerides, triolien, dioleolinolein, and fatty acids such as oleic, linoleic, palmitic, stearic, lauric, myristic and palmitoleic acids. Kernel of sweet almond contains sphingolipids, daucosterol and ß-sitosterol. Skin of the kernel contains flavonoid and phenolic antioxidant compounds including quercetin, naringenin, catechin and vanillic acid. The hulls of sweet almond contain ursolic acid, catechins and the terpenes such as betulinic acid, oleanolic acid and ursolic acid.7, 8 Almond is a rich source of vitamin E, mono unsaturated fatty acids, poly-unsaturated fatty acids, arginine and potassium.9

Almond also contains a wide variety of phenolic compounds which are localizes in skin of almond, including flavonols; isorhamnetin, kaempferol, quercetin, catechin and epicatechin), flavanones (naringenin), anthocyanins such as cyanidins and delohinidin, procyanidins, and phenolic acids like caffeic acid, ferulic acid, p-coumaric acid and vanillic acid.10 Active constituents of almonds are globulins such as amandine, albumin and amino acids. Sweet almond oil abundantly contains fatty acids like palimitic acid, palmitoleic acid, stearic acid, oleic acid, linoleic acid, alpha linoleic acid, arachidic acid, eicosanoic acid, behenic acid and erucic acid.11 Almonds are low in saturated fatty acids and rich in unsaturated fatty acids. It also contains fiber, phytosterols, plant protein, α-tocopherol, arginine, magnesium, copper, manganese, calcium and potassium.12
