Extended data:
Recent studies have shown that it has antioxidant, antiallergic, anti-obesity, hyperlipidemia and anti-tumor effects. The main active components found in it are coix lachryma-jobi polysaccharides A, B, C(CoixanA, B, C), neutral dextran 1~7,
And acidic polysaccharides CA- 1 and CA-2, coix seed ester, coix seed alcohol, lignans, phenols, various unsaturated fatty acids, benzoxazinone, oxanaphthone and triterpene ring-opening compounds such as squalene, sterols, adenosine and various amino acids.
Coix seed contains crude protein 13%~ 14% and fat 2%~8%. Among lipids, triacylglycerol 6 1%~64%, diacylglycerol 6%~7%, monoacylglycerol 4%, sterol ester 9%, and free fatty acid 17% ~ 18%.
The linoleic acid content in triacylglycerol can reach 25%-28%, and the linoleic acid content in free fatty acid is 27%-28%. Free fatty acids include palmitic acid, stearic acid, cis -8- octadecenoic acid, namely oleic acid, etc.
Among monoglycerides, α -monoglyceride has tumor effect, and among sterol esters, cis-trans feruloyl stigmasterol has ovulation promoting effect. The seed kernel also contains dextran with anti-complement effect, acidic polysaccharide and Coix lachryma-jobi polysaccharide with hypoglycemic effect.
Seed volatile oil contains 69 components, among which the main components are hexanal, hexanoic acid, hexyl 2- ethyl -3- hydroxybutyrate, γ-nonlactone, nonanoic acid, octanoic acid, ethyl palmitate, methyl linoleate, vanillin and ethyl linoleate.
