Abstract
The concentrations of erythorbic acid(ErA) and L-ascorbic acid(AsA) in the tissues of guinea pigs orally administered AsA or ErA Were measured over the passage of time using high-performance liquid chromatography. Guinea pigs were each administered 5mg AsA or 100mg ErA, and killed at a specified time thereafter. The AsA concentrations in the tissues of AsA-administered guinea pigs and the ErA concentratins in the tissues of ErA-administered guinea pigs increased for 3h after the respective administrations and decreased thereafter in both groups. The AsA concentration in the tissues of AsA-adminis-tered guinea pigs tended to be similar to the sum of AsA and ErA concentrations in the ErA-administered guinea pigs within 3 h after administration.
