The chemical compositions of gum oleoresins are distinction among different species, which leads a great diversity in properties of rosin and turpentine. Meanwhile, oleoresins of many pine species have their own characteristic components of abundant amounts. In order to utilize properly oleoresin as a renewable resource, it is necessary to investigate comprehensively and deeply the chemical characteristics of oleoresin of genus pinus. The publications of US professor Mirov N T Composition of Gum Turpentines of Pines (1961) demonstrated a systematic study on the composition of gum turpentines from 77 species winning great achievements. However, he could not investigate the chemical compositions of sesquiterpenes and diterpenes in the gum oleoresins because of the limited analytical conditions at that time. So the projects Study on chemical characteristics of gum oleoresins for Chinese pine species and their relation to taxonomy and Study on chemical characteristics of neutral components in oleoresins of pine genus and their relation to taxonomy were applied by the author, and approved by the National Foundation of Natural Science of China since 1987.
The research works were carried out in cooperation with senior engineers Liu Xing and Liang Zhiqin. Hundreds of oleoresin samples of more than 50 species were collected randomly in the central regions of each pine species. By a systematic study on these samples a lot of important scientific data was obtained, which provided a reliable support for chemotaxonomy of genus pinus, as well as layed theoretical bases for developing deeply processed products of naval stores. This book describes the scientific research results of the author and his colleague in this field for over 10 years.
