Abstract

Vegetable oils obtained from different plants are known for their beneficial effects on prophylaxis and supportive treatment of a great deal of inflammatory-mediated conditions. Their wide range of saturated and unsaturated fatty acids, and the presence of other ingredients (e.g., tocopherols, chlorophylls), provide them with anti-inflammatory, antioxidant and anticancer properties, which are worth being exploited. In this study, we have carried out the spectrofluorometric analysis of selected vegetable oils, namely apricot (Prunus armeniaca) kernel oil; blueberry (Vaccinium spp.) seed oil; argan (Argania spinosa) nut oil; kiwi (Actinidia deliciosa) seed oil; grape (Vitis vinifera) seed oil; evening primrose (Oenothera biennis) oil and meadowfoam (Limnanthes alba) seed oil, with the purpose to detect their fluorescent ingredients for further identification and bioactivity comparison. The obtained two- (2D) and three-dimensional (3D) emission spectra offered a complete description of the fluorescent components of the mixture and revealed different features for studied oils.

Highlights

There is a growing body of evidence on the potential biomedical uses of different vegetable oils [1].In this study, apricot (Prunus armeniaca) kernel oil; blueberry (Vaccinium spp.) seed oil; argan (Argania spinosa) nut oil; kiwi (Actinidia deliciosa) seed oil; grape (Vitis vinifera) seed oil; evening primrose (Oenothera biennis) oil; meadowfoam (Limnanthes alba) seed oil were chosen for spectrofluorimetric qualitative analysis in order to detect the active ingredients that determine their biomedical properties and further clinical use.Prunus armeniaca L. is a tree belonging to the Rosaceae family
This study aimed to develop a method of preparing oils for spectroscopic studies and evaluate the feasibility of total fluorescence spectroscopy for fingerprinting, identification and quality monitoring of oils
Namely: apricot (Prunus armeniaca) kernel oil; blueberry(Vaccinium spp.) seed oil; argan (Argania spinosa) nut oil; kiwi (Actinidia deliciosa) seed oil; grape (Vitis vinifera) seed oil; evening primrose (Oenothera biennis) oil; meadowfoam (Limnanthes alba) seed oil were sourced from The Kerfoot

Summary

Introduction

There is a growing body of evidence on the potential biomedical uses of different vegetable oils [1].In this study, apricot (Prunus armeniaca) kernel oil; blueberry (Vaccinium spp.) seed oil; argan (Argania spinosa) nut oil; kiwi (Actinidia deliciosa) seed oil; grape (Vitis vinifera) seed oil; evening primrose (Oenothera biennis) oil; meadowfoam (Limnanthes alba) seed oil were chosen for spectrofluorimetric qualitative analysis in order to detect the active ingredients that determine their biomedical properties and further clinical use.Prunus armeniaca L. (apricot) is a tree belonging to the Rosaceae family. Apricot (Prunus armeniaca) kernel oil; blueberry (Vaccinium spp.) seed oil; argan (Argania spinosa) nut oil; kiwi (Actinidia deliciosa) seed oil; grape (Vitis vinifera) seed oil; evening primrose (Oenothera biennis) oil; meadowfoam (Limnanthes alba) seed oil were chosen for spectrofluorimetric qualitative analysis in order to detect the active ingredients that determine their biomedical properties and further clinical use. An apricot kernel is a source of multiple proteins, fiber and cyanogenic compounds [2]. It contains high amounts of oleic (65 wt.%). The study results translate the need for further assessment of the clinical utility of apricot extracts and oil in different inflammatory-mediated conditions like UC [2,4]
