  • Received Date: 2006-07-13
  • The variations of berry characters, amino acid, lycopene,β2carotene as well as micro elements weremeasured for autumn olive berries collected in various seed sources and individuals. The average weight of fresh berries was 0. 13 gwith the range from 0. 07~0. 15 g. The average rate of berry pulp was 75. 01%. The total contentof 17 amino acids in 6 individual p lants ranged from 146. 596 to 179. 634 mg·g-1 with average of 167. 839 mg·g-1 , ofwhich relative content of glutamic acid to total amino acidswas the highest (18. 07% ) , followed by arginine(11166% ) and asparagines (10. 78% ) , and the lowest were methionine ( 0. 84% ) , and others (7. 00% ). Thelycopene content in 3 individual p lants ranged from 78. 000 to 342. 000 mg·kg-1 and was 2. 6 to 11. 4 times that infresh tomato. The averages ofβ-carotene, dissolvable sugar, dissociative acids and Vc are 6. 480 mg·kg-1 , 7. 310mg·kg-1 , 3. 24 mg·g-1 and 0. 049 mg·g-1 respectively. The average content of Fe, Mn, Zn, Cu were 97. 881,77. 553, 23. 384 and 12. 129 mg·kg-1 , and K, Ca were 11. 190 and 3. 720 mg·g-1 separately.
