Analysis and evaluation of nutritional components of Kadsura coccinea seeds

In order to rationally develop and utilize the Kadsura coccinea (K. coccinea) seeds, its nutrient components were determined. The results showed that K. coccinea seeds were rich in nutrients, mainly crude fat, followed by crude protein and sugar. K. coccinea seeds were rich in unsaturated fatty acids, accounting for 81.89% of the total fatty acids, and linoleic acid accounted for 88.89% of the unsaturated fatty acids. The polysaccharide of K. coccinea seeds was composed of 9 kinds of monosaccharides, including mannose, rhamnose, glucuronic acid, galacturonic acid, glucose, galactose, xylose, arabinose and fucose, with galactose and arabinose being the main ones. Both free amino acids and hydrolyzed amino acids in K. coccinea seeds contained 7 kinds of essential amino acids for human body, with a relatively complete variety of amino acids. Meanwhile, 25 kinds of volatile components were identified in K. coccinea seeds, and terpenes were the main volatile components. The seeds were also rich in mineral elements, including potassium, magnesium, phosphorus, manganese, iron, zinc and other elements, so K. coccinea seeds had great development value for its nutritional and medicinal values.
