STUDIES ON ANTIOXIDANT PROPERTIES OF THE DIFFERENT SOLVENT EXTRACTS AND FATTY ACID COMPOSITION OFHYOSCYAMUS RETICULATUSL.

Abstract

Hyoscyamus reticulatus (Solanaceae) is distributed in the Mediterranean, East and Central Anatolia regions of Turkey. In the present study, antioxidant properties of the various extracts of H. reticulatus were evaluated by seven different chemical assays, namely total phenolics and flavonoids content, total antioxidant capacity, free radical (2,2‐diphenyl‐1‐picrylhydrazyl)‐scavenging assay, β‐carotene/linoleic acid test system, and ferric‐ and cupric ion‐reducing power. The strongest antioxidant properties were obtained by ethanolic extract. The order of the antioxidant properties of extracts were ethanolic > methanolic > acetone. Fatty acid composition of the aerial parts of H. reticulatus was analyzed by gas chromatography. The main fatty acids of the oil gave the proportions C 12:0 (lauric acid), C 10:0 (capric acid) and C 11:0 (undecanoic acid). Results of the present study demonstrated that the extracts and oil of H. reticulatus may be used as a source of natural antioxidant and lauric acid in the food and pharmaceutical industries. PRACTICAL APPLICATIONS Hyoscyamus species contain important tropane alkaloids, which have antispasmodic, anticholinergic, analgesic and sedative effects. In this study, antioxidant properties of the various extracts of Hyoscyamus reticulatus were investigated by seven different chemical assays. The results of the present study may be important as an indication of pharmacological and food processing utility of the plant. H. reticulatus can be considered as a source of both natural antioxidants and lauric acid in food industry and pharmacological applications.

“…For instance, squalene is identified as one of the major compounds in AMF and reported to possess antioxidant (Kohno et al 1995) and chemopreventive activities (Newmark 1997;Musakeshavarz & Abdul-Reza 2012). Among other identified components, dodecanoic acid (Guler 2012) is reported to have antioxidant and antimicrobial activities. Tetradecanoic acid and hexadecanoic acid are reported to be antioxidant, anti-inflammatory and cancer preventive effects (Bodoprost and Rosemeyer 2007).…”

Determination of the Content of Hyoscyamus Reticulatus Seeds by XRF Method and Antibacterial Characteristics of Ethyl Alcohol Extract

“…Since it has pharmacologically active substances, it has attracted the attention of researchers, and antioxidant and antimicrobial studies of this species have been reported. When the ethanolic extract of H. reticulatus leaves was analyzed, total phenolic content was found to be 130.06 mg/g and total flavonoid content was 243.7 mg/g [3]. Although there are no data on material losses due to poisoning caused by poisonous plants in Turkey, it is reported that approximately 3%-5% of animals are poisoned with plants every year in countries where pasture improvement is done, such as the United States [4].…”

“…The poisoning of two people who ate fresh shoots of Hyoscyamus niger because of its similarity to lettuce is an example, and henbane poisoning is common in Eastern Anatolia [5,6,7]. Consumption of the fresh shoots, roots, and seeds of H. niger can cause hallucinations, blurred vision, increased heart rhythm, and death [2,3,8,9]. Similarly, a 71-year-old patient with a diagnosis of bronchial asthma drank tea made from the leaves of many henbane plants because he had heard it was good for asthma, and approximately two hours later, he was hospitalized with symptoms including visual and speech disorders, dry mouth, and palpitations [10].…”
