Embodiment

[0036] The invention discloses a method for extracting pepper leaf essential oil by ultrasonic-assisted distillation in a deep eutectic solvent method. The deep eutectic solvent DES is composed of a hydrogen bond acceptor HBA and a hydrogen bond donor HBD in a certain molar ratio, and the deep eutectic solvent DES is used. Extraction of essential oil from pepper leaves by ultrasonic-assisted distillation; the main steps include:

[0037] ① Clean the fresh pepper leaves, dry them in an electric blast drying oven at 40°C-80°C to a constant weight, crush and sieve them into 30-80 mesh pepper leaf powder, and dry them in a desiccator for later use;

[0038] ②Prepare the deep eutectic solvent DES, hydrogen bond acceptor HBA and hydrogen bond donor HBD in a constant warm water bath at 70°C-90°C, mix, heat and stir for 30-120 minutes until a uniform colorless and transparent liquid is formed Deep eutectic solvent DES;

[0039] ③According to the liquid-to-solid ratio of deep eutectic...

Abstract

The invention discloses a method for extracting pepper leaf essential oil through a combination of a deep eutectic solvent method and ultrasonic-assisted distillation. According to the method, a deepeutectic solvent (DES) is formed by a hydrogen bond acceptor (HBA) and a hydrogen bond donor (HBD) according to a certain molar ratio, and essential oil is extracted from pepper leaves through ultrasonic-assisted distillation by using the DES. The method comprises the following main steps: (1) cleaning, drying and crushing fresh pepper leaves; (2) preparing the DES; (3) carrying out ultrasonic-assisted treatment on the DES and pepper leaf powder; and (4) extracting the pepper leaf essential oil. The method has the beneficial effects that optimal extraction process conditions responsive to surface optimization are as follows: a choline chloride-urea deep eutectic solvent is used as the optimal extraction agent, a liquid-to-solid ratio is 14: 1 (mL / g), microwave power is 300 W, and extraction time is 53 minutes. The extraction method is simple, and the yield of the pepper leaf essential oil is increased; essential oil components are analyzed by adopting gas chromatography-mass spectrometry; a new thought is provided for essential oil extraction method; and meanwhile, the application range of the DES is also expanded.

Description

technical field [0001] The invention relates to a method for extracting plant essential oils, in particular to a method for extracting pepper leaf essential oils through a deep eutectic solvent method plus ultrasonic-assisted distillation. Background technique [0002] Pepper (Piper nigrum L.) is a perennial evergreen flowering vine belonging to the family Piperaceae. It is a characteristic agricultural product in Hainan, accounting for more than 90% of the total pepper production in the country. In the field of traditional medicine, pepper is a very widely used medicine. Locals in Thailand can buy pepper leaves and stems at markets, suggesting that pepper leaves can be used to treat certain ailments. Because essential oil has anti-oxidation, antibacterial and other activities, it can be used in food preservation and cosmetic industry. In addition, essential oils are rich in chemical components and have certain health benefits, such as anti-inflammatory, blood circulation ...
