Abstract

Callistemon viminalis leaves exhibit outstanding functional activities and high concentration of essential oil. In order to completely develop its extraction method, the raw materials were pretreated using inorganic salts by salting-out hydrolysis, and the essential oil was subsequently extracted using hydrodistillation. Gas mass spectrometry was used to analyze the essential oil's chemical compounds. The ideal concentration of NaCl was 3 %, the liquid-solid ratio was 3.0 mL/g, and the separation period was 2.4 h. The 9.30 mL/kg DW was maximum essential oil production, 36.88 % higher than hydrodistillation process. Additionally, leaves, flowers, flower buds, and stems included 60 different types of essential oils made of compounds. The essential oil has fungal against activity of 87.12 %. The minimum inhibitory concentration and minimum fungicidal concentration of essential oil against Colletotrichum fructicola and Colletotrichum acutatum were 0.15 and 1 µL/mL, respectively. These results indicate that the essential oil of Callistemon viminalis has potential as natural agents.

采用盐析辅助加氢蒸馏法提取金盏花精油，提高了金盏花的体外抗氧化和抗真菌性能

藿香叶具有突出的功能活性和高浓度的精油。为了完善其提取方法，采用无机盐水解盐析法对原料进行预处理，然后采用加氢蒸馏法提取精油。采用气相质谱法分析精油的化学成分。NaCl的理想浓度为3 %，液固比为3.0 mL/g，分离周期为2.4 h。该工艺最大精油产量为9.30 mL/kg DW，比加氢蒸馏工艺高36.88 %。此外，叶子，花，花蕾和茎包括60种不同类型的化合物精油。精油抗真菌活性为87.12 %。精油对果炭疽菌的最低抑菌浓度为0.15 μ L/mL，对针状炭疽菌的最低杀菌浓度为1 µL/mL。这些结果表明，金盏花精油具有作为天然制剂的潜力。

期刊介绍： Industrial Crops and Products is an International Journal publishing academic and industrial research on industrial (defined as non-food/non-feed) crops and products. Papers concern both crop-oriented and bio-based materials from crops-oriented research, and should be of interest to an international audience, hypothesis driven, and where comparisons are made statistics performed.
