Embodiment 1

[0039] Embodiment 1, the method that response surface method optimizes the essential oil extraction process of pomegranate cortex:

[0040] 1. Sample preparation

[0041] 1. Sample preparation

[0042] Dried pomegranate skin to a moisture content of ≤8% (weight content), crushed, passed through a 60-mesh sieve, and used as a sample.

[0043] Weigh 1.00g of the sample with a balance, add petroleum ether according to the material ratio, extract at different temperatures for a certain period of time, filter the extracted solution, reclaim the filtrate, reclaim the petroleum ether in the filtrate with a rotary evaporator, and obtain the aroma essential oils.

[0044] 2. Experimental Design and Statistical Analysis

[0045] 1. Single factor experiment

[0046] Change the extraction temperature, extraction time, and material ratio to conduct a single factor experiment to determine the content of essential oil of Wendan Pi. Each treatment was repeated three times.

Abstract

The invention discloses an extraction process of a pomelo peel essential oil. The process comprises steps of: mixing pomelo peel with petroleum ether according to a liquid to material ratio of 25-26ml petroleum ether / g pomelo peel; extracting at 48.5-49 DEG C for 1.8-1.9 h to obtain a pomelo peel essential oil extract; and recovering petroleum ether in the pomelo peel essential oil extract to obtain a pomelo peel essential oil. The invention also discloses a response surface method for optimizing the extraction method of the pomelo peel essential oil. Three variables are set up: liquid-material ratio of the pomelo peel and petroleum ether, extraction temperature and extraction time; and a piece of design expert software is employed for optimization according to the a Box-Behnken design principle. The obtained pomelo peel essential oil is analyzed by gas chromatography-mass spectrometry, and comprises the following main components, by weight: 15.67% of alpha-pinene, 19.69% of D-limonene, 13.39% of friedelin, and 8.35% of arbricolin.

Description

technical field [0001] The present invention relates to a method for optimizing the extraction conditions of the essential oil of pomegranate cortex and an analysis of the components of the essential oil, in particular to a method for optimizing the conditions for the extraction of the essential oil of pompondan cortex by using the response surface method. Background technique [0002] Wendan is a kind of grapefruit of the Rutaceae plant, which is mainly produced in Yuhuan, Zhejiang, my country. Bonito is fragrant, sweet and sour, cool, nutritious, and has high medicinal value. It is also a fruit with therapeutic benefits recognized by the medical field. Essential oil, also known as volatile oil, is a general term for a class of oily liquid substances that have an aromatic odor and can volatilize at room temperature contained in the oil cells of grapefruit epidermis. It is composed of terpenes, alcohols, aldehydes and esters, the main components are limonene, myrcene, caryo...
