Sugars and organic acids in Korean hot pepper fruit (C, annuum L.) according to its portions, pericarp, seeds and placenta, were determined by gas liquid chromatography (GLC). ${\alpha}-\;and\;{\beta}-fructoses,\;{\alpha}-\;and\;{\beta}-glucoses$, galactose, sucrose and maltose were identified. Major sugar in pericarp was fructose, while those in seeds and placenta were surose and fructose. Amount of free sugars in seeds was higher than that in pericarp or placenta. Succinic, fumaric, malic, tartaric, citric and quinic acids were found. Citric acid was a major organic acid found in pericarp and placenta. The amount of each identified organic acid, however, was similar in seeds. Quantity of total organic acids identified in pericarp or placenta was higher than that in seeds.
