The efficacy and function of raw coix seed

Raw coix seed is rich in value, carbohydrates, and a small amount of vitamins and trace elements, so it is good for the human body and is very popular. However, everyone should pay attention to the fact that processed aconite may cause mild indigestion during use. You must wash your hands before eating it, and you should also move your body after eating to speed up digestion and promote gastrointestinal motility.

Main Value

The dried seed kernel is spherical or ellipsoidal, with a wide and slightly flat base and a blunt apex. It is 5-7 mm long and about 3-5 mm wide. The surface is white or yellowish white, smooth or with unclear longitudinal stripes, sometimes with residual yellowish-brown outer skin. There is a deep and wide longitudinal groove on the side, the bottom of the groove is rough and brown, the base is concave, and there is a small brown dot in it. It is hard and when broken open, the inside is white and powdery. It has a slight odor and a sweet and light taste. The best ones are large, plump, white and complete. Chemical composition

The seed kernel contains 16.2% protein, 4.65% fat, 79.17% carbohydrates, and a small amount of vitamin B1 (330 micrograms%). The seeds contain amino acids (leucine, lysine, arginine, tyrosine, etc.), coixol, coix ester, and triterpenoid compounds.

Pharmacological Action

1. The effect of coix seed oil: According to early reports, coix seed oil extracted with petroleum ether has an excitatory effect on the striated muscles and motor nerve endings of frogs at low concentrations and a paralyzing effect at high concentrations.

If injected into the frog's thoracic lymph cavity or gastrocnemius muscle, it can reduce muscle contracture and shorten its fatigue curve.

Using isolated frog neuromuscular specimens, it was demonstrated that the point of action was not on the nerve trunk but on the muscle part.

Further research indicates that coix seed oil or saturated fatty acids with a C number of 10 to 18 can prevent or reduce the contraction of skeletal muscle (not the neuromuscular junction), while unsaturated fatty acids (such as oleic acid) have no such effect.

Coix seed oil (0.5 g/kg injected subcutaneously in rabbits) and fatty acids with a C number above 12 can lower blood sugar, which can be antagonized by pyruvate. Serum calcium is also reduced. Fatty acids with a lower C number (such as capric acid) have no effect on blood sugar or blood calcium.

Job's tears oil (mainly palmitic acid and its esters) is good for breathing, small amounts of which can stimulate

Massive paralysis (central); can cause significant dilation of pulmonary blood vessels.

Low concentrations have an excitatory effect on isolated frog hearts and isolated rabbit intestines, while high concentrations have an inhibitory effect. It generally has an excitatory effect on rabbit and guinea pig uteri, and adrenaline can reverse its excitatory effect. It also has an antidiuretic effect. Large amounts can paralyze animals and cause respiratory arrest.
