Nutrient and Medicinal Components in Gnetum parvifolium Seeds

  • Received Date: 2013-02-19
  • The contents of water, sugar, fatty acid, amino acids, stilbenoid and flavonoid in the seeds of Gnetum parvifolium (Warb.) C. Y. Cheng were measured. The results show that the seeds of G. parvifolium contain abundant nutritional materials. The seeds are oblong and thousand kernel weight is (2 525.67±44.54)g. The water content is (373.5±0.82)g·kg-1, the total sugar content is (496.8±4.78)g·kg-1, the total fat content is (29.1±0.21)g·kg-1, the total amino-acid content is (73.9±1.05)g·kg-1, the total flavone content is (123.2±1.73)g·kg-1; the resveratrol, isorhapontigenin and gnetol contents are (2 231.0±1.65) mg·kg-1, (1 471.7±0.72) mg·kg-1 and (212.0±1.47) mg·kg-1 respectively. The seeds contain almost all kinds of amino-acid, including 8 kinds of essential amino acids. But cystine is not found. The index of unsaturated fatty acid and the polysaccharide are high while the disaccharide, glucose and fructose in that are low. There are high contents of isorhapontigenin and total flavone in the seeds of G. parvifolium.

Abstract: The contents of water, sugar, fatty acid, amino acids, stilbenoid and flavonoid in the seeds of Gnetum parvifolium (Warb.) C. Y. Cheng were measured. The results show that the seeds of G. parvifolium contain abundant nutritional materials. The seeds are oblong and thousand kernel weight is (2 525.67±44.54)g. The water content is (373.5±0.82)g·kg-1, the total sugar content is (496.8±4.78)g·kg-1, the total fat content is (29.1±0.21)g·kg-1, the total amino-acid content is (73.9±1.05)g·kg-1, the total flavone content is (123.2±1.73)g·kg-1; the resveratrol, isorhapontigenin and gnetol contents are (2 231.0±1.65) mg·kg-1, (1 471.7±0.72) mg·kg-1 and (212.0±1.47) mg·kg-1 respectively. The seeds contain almost all kinds of amino-acid, including 8 kinds of essential amino acids. But cystine is not found. The index of unsaturated fatty acid and the polysaccharide are high while the disaccharide, glucose and fructose in that are low. There are high contents of isorhapontigenin and total flavone in the seeds of G. parvifolium.
