Abstract

ABSTRACT This work aimed to obtain and investigate the properties and composition of extracts from flowers of Acacia mearnsii; this tree is widely cultivated because the bark is used as a raw material for various industry segments, but the flowers are not yet explored. The essential oil was evaluated by GC/FID, GC/MS, and GC/O. The antioxidant activity (DPPH and phosphomolybdenum methods) and chemical composition were investigated for a water-soluble extract, a by-product of the extraction process. 85.8% of the compounds present in the essential oil were identified, 8-heptadecene being the major compound. The main scents detected by the olfactory analysis were roast nutty, coffee, sweet, and floral. The water-soluble extract showed antioxidant activity that may be related to phenolic compounds. Results obtained from the LC-qTOF/MS analysis have shown that 25 likely flavonoids, such as naringenin, myricetin, quercetin, and rutin are present in the extract.

金合欢花水蒸气蒸馏法提取精油及水溶性提取物的研究

摘要:本文旨在对金合欢花提取物的性质和成分进行研究;这种树被广泛种植，因为树皮被用作各种工业部门的原料，但花朵尚未被探索。采用GC/FID、GC/MS、GC/O对精油进行评价。采用DPPH法和磷钼法研究了水溶提取物的抗氧化活性和化学成分。经鉴定，挥发油中含有85.8%的化合物，8-十七烯为主要化合物。嗅觉分析检测到的主要气味是烘焙坚果味、咖啡味、甜味和花香。水溶性提取物的抗氧化活性可能与酚类化合物有关。LC-qTOF/MS分析结果表明，提取物中含有柚皮素、杨梅素、槲皮素、芦丁等25种黄酮类化合物。

期刊介绍： Journal of Essential Oil Research ( JEOR) is the major forum for the publication of essential oil research and analysis. Each issue includes studies performed on the chemical composition of some of the 20,000 aromatic plants known in the plant kingdom. JEOR is devoted entirely to all phases of research from every corner of the world by the experts in their field. JEOR''s main areas of focus include: -Analytical chemistry- Biological activity- Biotechnology- Chemical composition- Chemical synthesis- Chemosystematics- Microbiological activity- Plant biochemistry/biosynthesis- Toxicology. Published six times per year, JEOR provides articles on the aromatic principles of a plant or its isolates and are directed toward furthering our readers'' knowledge of the aromatic plant and animal kingdoms.
