Abstract

: This study was aimed to evaluate the physicochemical properties and chemical profile of seeds oil obtained from new seven sunflower ( Helianthus annuus L.) lines as well as their antioxidant and enzyme inhibition activity. The seeds powder was extracted by maceration in n-hexane. The oil content of the seven lines was ranged from 20.04% to 36.65% and was either yellow or pale yellow in color. No significant variations were observed on the refractive index (1.46 unit) of the oil. Oils of the seven lines were significantly ( p ˂ 0.05) different in their saponification values (32.13–282.66 mg KOH/g oil), peroxide values (1.76–13.26 mg KOH/g-oil), acid values (0.016–1.766 mg KOH/g oil) and free fatty acids content (6.26–72.23 mg KOH/g-oil). The chemical profile of the oil revealed that line APO42 contained the highest amount of monounsaturated fatty acids (55.9%). All the seven lines contained a considerable amount of linoleic acid (27.5%– 42.5%), and it represented the major compound in lines BOH3 (42.5%) and H1733 (39.8%). The variation was remarkable in their oleic acid content where the highest amount was observed in lines APO42 (55.4%) and APO43 (42.2%), respectively. Lines BOH3, APO43, APO41, and H1733 exerted the best total antioxidant activity in addition to their capacity to reduce Cu 2+ and Fe 3+ , while lines H1733 and APO43 had a metal chelating activity as well. All oils showed weak acetylcholinesterase, butyrylcholinesterase, α-glucosidase and α-amylase inhibitory activities. Only four lines showed considerable enzyme inhibitory activity against tyrosinase enzymes. Multivariance analysis suggested that linoleic acid participated in the observed biological activity of the oils. In conclusion, these new lines might contribute to the nutritional and phytotherapeutic properties of sunflower oil in addition to other industrial applications.

7个向日葵新品系种子油脂理化性质、抗氧化及酶抑制活性的比较研究

摘要:本研究旨在评价7个向日葵新品系种子油的理化性质、化学性质及其抗氧化和酶抑制活性。采用正己烷浸渍法提取种子粉。7个品系的含油量在20.04% ~ 36.65%之间，颜色为黄色或淡黄色。油的折射率(1.46单位)无明显变化。7个品系的皂化值(32.13 ~ 282.66 mg KOH/g油)、过氧化值(1.76 ~ 13.26 mg KOH/g油)、酸值(0.016 ~ 1.766 mg KOH/g油)和游离脂肪酸含量(6.26 ~ 72.23 mg KOH/g油)差异显著(p小于0.05)。结果表明，APO42系的单不饱和脂肪酸含量最高(55.9%)。7个品系均含有相当数量的亚油酸(27.5% ~ 42.5%)，以BOH3(42.5%)和H1733(39.8%)为主要化合物。油酸含量差异显著，其中APO42和APO43的油酸含量最高，分别为55.4%和42.2%。品系BOH3、APO43、APO41和H1733除具有还原Cu 2+和Fe 3+的能力外，总抗氧化活性最好，而品系H1733和APO43也具有金属螯合活性。所有油脂均表现出较弱的乙酰胆碱酯酶、丁基胆碱酯酶、α-葡萄糖苷酶和α-淀粉酶抑制活性。只有4个品系对酪氨酸酶表现出明显的抑制活性。多因素分析表明，亚油酸参与了所观察到的油的生物活性。总之，这些新品系可能有助于葵花籽油的营养和植物治疗特性以及其他工业应用。

期刊介绍： The Turkish Journal of Botany is published electronically 6 times a year by the Scientific and Technological Research Council of Turkey (TÜBİTAK) and accepts manuscripts (in English) covering all areas of plant biology (including genetics, evolution, systematics, structure, function, development, diversity, conservation biology, biogeography, paleobotany, ontogeny, functional morphology, ecology, reproductive biology, and pollination biology), all levels of organisation (molecular to ecosystem), and all plant groups and allied organisms (algae, fungi, and lichens). Authors are required to frame their research questions and discuss their results in terms of major questions in plant biology. In general, papers that are too narrowly focused, purely descriptive, or broad surveys, or that contain only preliminary data or natural history, will not be considered (*). The following types of article will be considered: 1. Research articles: Original research in various fields of botany will be evaluated as research articles. 2. Research notes: These include articles such as preliminary notes on a study or manuscripts on the morphological, anatomical, cytological, physiological, biochemical, and other properties of plant, algae, lichen and fungi species. 3. Reviews: Reviews of recent developments, improvements, discoveries, and ideas in various fields of botany. 4. Letters to the editor: These include opinions, comments relating to the publishing policy of the Turkish Journal of Botany, news, and suggestions. Letters should not exceed one journal page. (*) 1. Raw floristic lists (of algae, lichens, fungi, or plants), species descriptions, chorological studies, and plant sociology studies without any additional independent approaches. 2. Comparative morphology and anatomy studies (that do not cover a family, tribe, subtribe, genus, subgenus, section, subsection, or species complexes with taxonomical problems) without one or more independent additional approaches such as phylogenetical, micromorphological, chromosomal and anatomical analyses. 3. Revisions of family, tribe, genus, subgenus, section, subsection, or species complexes without any original outputs such as taxonomical status changes, IUCN categories, and phenological and ecological analyses. 4. New taxa of all plants without any additional independent approaches such as phylogenetical, ecological, chromosomal, chorological and correlational analyses in addition to a detailed macro- and micro-morphological descriptions with quality field and microscopic illustrations of taxonomically important structures and identification key in the taxonomic group. New records of all plants without any additional independent approaches such as phylogenetical, ecological, chromosomal, chorological and correlational analyses in addition to a detailed macro- and micro-morphological descriptions with quality field and microscopic illustrations of taxonomically important structures and identification key in the taxonomic group may be accepted for peer review if they contain 3 or more new records or taxonomical status update, such as lectotypification, new combinations, transfers, revivals and synonyms. 5. New taxa of algae, lichens, and fungi without any additional independent approaches such as phylogenetical, ecological, chromosomal, chorological and correlational analyses in addition to a detailed macro- and micro-morphological descriptions with quality field and microscopic illustrations of taxonomically important structures and identification key in the taxonomic group. New records of algae, lichens, and fungi without any additional independent approaches such as phylogenetical, ecological, chromosomal, chorological and correlational analyses in addition to a detailed macro- and micro-morphological descriptions with quality field and microscopic illustrations of taxonomically important structures and identification key in the taxonomic group may be accepted for peer review if they contain 5 or more new records or taxonomical status update, such as lectotypification, new combinations, transfers, revivals and synonyms.
