Rheological properties of monoterpene compounds

Abstract

Monoterpenes are the most interesting substrates with biological and chemical properties. Nowadays monoterpens structure didn’t clearly recognized by several modern methods.

A number of representatives of the terpene series from relevant literature sources were considered to compare their chemical activity, predict obstacles to rheological detection in order to avoid key errors in analytical analyses such as electrophoresis. To determine several qualities of it monoterpene contanting structure was observed and investigated by spectrophotometer and capillar phoresis. In this study, a colorimetric indicator assay was developed for rapid determination of monoterpenes in sweet orange (Citrus sinensis) essential oils. Сapillar electrophoresis results showed that the main components in citrus essential oil are citral, which elicited greater extents of color changes as compared to other monoterpenes (limonene, α-pinene, β-pinene and terpinolene). The colorimetric indicator is potentially useful for rapid assessment of monoterpene oxidation in citrus essential oil and other citrus-based products.
