Description
It is yellow coloured liquid of strong acrid odour until
refined, sp. gr. 0.914–0.923, saponification value 173–184, iodine value
96–194, and unsaponifiable matter 0.9–1.0%.
Chemical Constituents
Mustard oil contains glycerides of arachidic (0.5%), behenic
(2–3%), eicosenoic (7–8%), erusic (40–60%), lignoceric (1–2%), linoleic
(14–18%), linolenic (6.5–7.0%), oleic (20–22%), and myristic (0.5–10%) acids.
Black mustard seeds contain 35–40% of fixed oil and a
glycoside known as sinigrin along with an enzyme myrosin. Allyl isothiocynate
is responsible for the strong acrid smell of volatile oil of mustard produced
on hydrolysis of glycoside.
Uses
Fixed oil is used as edible oil after refining, but
medicinal properties are due to allyl isothiocynate, which is a local irritant
and emetic. If applied externally, it is rubefacient and vasicant. It is also
used as condiment and in manufacture of soap. Refined mustard oil is used in
vegetable ghee.
