Abstract
(1) Fatty acids in essential oils of tea leaves (four kinds of essential oils previously reported, are represented as C-(l), W-(1), C-(2) and W-(2)) and green tea were iden-tified by paper chromatography.
(i) Acetic, propionic, n-butyric, isobutyric, isovaleric and caproic acid were found in C-(1) and W-(1). These acids have been reported by Takei et al.
(ii) Caprylic acid was found in W-(1), W-(2) and in the essential oil of green tea, but not in C-(l) and C-(2).
(iii) Formic acid was found in C-(1), W-(1) and W-(2). The presence of this acid in fresh tea-leaves has not been reported previously.
(2) Palmitic acid was obtained in a pure form from C-(1) and W-(1), by standing at -24°_??_-26°C.
