Abstract
The powders (80-100 mesh) of Fossilia Ossis Mastodi (Japanese name "Ryukotsu") were extracted with ethylether and, from the soluble portion a crystalline component (I) and some oils (II) were isolated. I showed mp 205.5°, [α]20D+24.8° and was examined by gas chromatography and infrared spectrum. It was identified with d-borneol. II are now under investigation. Using aqueous infusion of the powders above mentioned, amino acid and fatty acid components were examined by gas chromatography and paper partition chromatography. Acetic acid, propionic acid, butyric acid, isobutyric acid, valeric acid, isovaleric acid, and caproic acid were identified from the aqueous solution. Amino acids are at present under study.
