• High-Performance Liquid Chromatographic Analysis of Amino Acids in Ackee Fruit with Emphasis on the Toxic Amino Acid Hypoglycin A
  作者：K. D. Golden、O. J. Williams、Y. Bailey-Shaw

  DOI：10.1093/chromsci/40.8.441

  日期：2002.9.1

  High-performance liquid chromatography is used to determine the amino acid content of ripe and unripe ackee fruit. Specific emphasis is placed on the level of the toxic amino acid hypoglycin A (hyp-A) in the unripe and ripe ackee fruit and seed. Unripe samples are found to contain significantly higher quantities (P < 0.05) of hyp-A when compared with ripe samples. Uncooked unripe fruit is found to contain 124.4 ± 6.7 mg/100 g fresh weight and uncooked ripe fruit 6.4 ± 1.1 mg/100 g fresh weight. The seed of the uncooked unripe fruit is found to contain 142.8 ± 8.8 mg/100 g fresh weight, and the seed of uncooked ripe fruit has 106.0 ± 5.4 mg/100 g fresh weight. Boiling fruit in water for approximately 30 min is efficient in removing hyp-A from the edible arilli; however, low levels of 0.54 ± 0.15 mg/200 mL are detected in the water that was used to cook the ripe fruit. The average %recovery of the amino acids was 80.34%.

  高效液相色谱用于测定成熟和未成熟的阿基果中的氨基酸含量。特别强调未成熟和成熟阿基果及种子中有毒氨基酸氢糖酸A（hyp-A）的水平。与成熟样本相比，未成熟样本中发现的hyp-A含量显著更高（P < 0.05）。未熟阿基果在未烹煮状态下的含量为124.4 ± 6.7 mg/100 g鲜重，而成熟阿基果则为6.4 ± 1.1 mg/100 g鲜重。未成熟阿基果的种子含有142.8 ± 8.8 mg/100 g鲜重，而成熟阿基果的种子为106.0 ± 5.4 mg/100 g鲜重。将水果在水中煮约30分钟能有效去除可食用的果肉中的hyp-A；然而，在煮熟成熟水果的水中仍检测到低水平的0.54 ± 0.15 mg/200 mL。氨基酸的平均回收率为80.34%。

• A High Chemical Reactivity of 5-Azidouracils and Its Synthetic Application: Novel Synthesis of 8-Substituted 1,3-Dimethylxanthine Derivatives
  作者：Kosaku Hirota、Magoichi Sako、Hironao Sajiki

  DOI：10.3987/com-97-s68

  日期：——

  A novel method for the preparation of 8-substituted 1,3-dimethylxanthine derivatives (7 or 8) is described: treatment of 6-alkylamino-5-bromo-1,3-dimethyluracils (6a-e), easily prepared by bromination of the corresponding 6-alkylamino-1, 3-dimethyluracils (5), with sodium azide in DMF at ambient temperature allowed the direct formation of the 8-substituted 1,3-dimethylxanthines (7) proceeding via a transient formation of the corresponding 5-azido-1 ,3-dimethyluracils. The 5-bromo-1,3-dimethyluracils (6f, g) possessing an ct-branched alkylamino group at the 6-position similarly react with sodium azide to afford 8,8-disubstituted 1,3-dimethyl-8H-xanthines (8,8-disubstituted 1,3-dimethyl-3,g-dihydropurine-2,6-diones)(8).

  日期：——

  A series of hydurilic acid derivatives (5,5'-bipyrimidinyl-2,4,6,2',4',6'-hexaones) including several new derivatives was synthesized from 5,6-diaminouracils. Mechanisms for their formation are proposed and discussed. Furthermore, a new method for the preparation of pyrimidine-2,4,5,6-tetraone-5-oxime derivatives (violuric acids) was found starting from 5-amino-6-nitrosouracils.
