This report examines the taxonomic distribution of the in vitro biosynthesis of ascorbic acid in the Prosimii (Order: Primates). Liver and kidney samples of 15 prosimian taxa, including Tarsius bancanus, were quantitatively tested for the enzyme L-gulono-1,4-lactone oxidase. Liver samples from all taxa except Tarsius had substantial levels of the enzyme. Furthermore, unlike other eutherian mammals, kidney tissue from members of the family Lemuridae showed low but consistent levels of enzyme activity. The result for Tarsius, by fitting with the pattern exhibited by the monkeys, apes, and man, adds significant independent evidence for this animal's relatively close genetic relationship with the Anthropoidea.
本报告研究了原猴亚目（灵长目）中抗坏血酸体外生物合成的分类分布情况。对包括眼镜猴在内的15种原猴类群的肝脏和肾脏样本进行了L-古洛糖酸-1,4-内酯氧化酶的定量检测。除眼镜猴外，所有类群的肝脏样本中该酶都有大量存在。此外，与其他真兽亚纲哺乳动物不同，狐猴科成员的肾脏组织中酶活性水平较低但较为稳定。眼镜猴的检测结果与猴子、猿类和人类呈现的模式相符，为该动物与类人猿相对密切的遗传关系增添了重要的独立证据。
