essential oil of the orange peel which was extracted by hydrodistillation method showed 50 different mono- and sesquiterpenes on gc-ms analysis, in which limonene had the highest percentage (92.4%). due to various important uses of the compound, a method was developed for isolation and purification of limonene. in this method, for extra purification, a fractional distillation on vigreux column ...

Orotic acid-C1402H, which was required for biological studies being pursued in this laboratory, has been synthesized by the method of Nyc and Mitchell,5 starting with DL-aspartic acid-a-C1402H. The latter was prepared from ethyl malonate-C1402C2H5, as described by Galat.' This orotic acid probably contains the isotopic carbon exclusively in the carboxyl group since it evolves carbon dioxide con...
