Natural Resin Materials - Spectral and Chromatographic Investigations

Abstract

Natural coniferous resins are recognized as raw materials for various products, are liquid hydrocarbon secretions of many plants, and are mainly composed of volatile and nonvolatile terpenes and essential oils. Some resins, particularly in conifers, contain a mixture of diterpenic, organic carboxylic acids, called resin acids. The resins can be found in solid or semisolid states, they are not soluble in water but are soluble in alcohol. The chemical composition, and structure of different coniferous resins elevated from Dâmbovița County, Romania, are investigated and discussed in this paper.
