Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] A method based on response surface methodology to optimize process parameters for the extraction of volatile oil from Angelica sinensis. The angelica described in this method is a new variety of Angelica sinensis "Mingui No. 3" bred by heavy ion irradiation biological breeding technology, which is Angelica sinensis (Oliv. ) the dry root of Diels, it comprises the following steps:

[0027] Step 1. Pretreatment of medicinal materials: Weigh an appropriate amount of Chinese angelica medicinal materials, wash them with water, dry them in a 40°C oven until they reach a constant weight, and crush them into 1cm blocks;

[0028] Step 2, using the steam distillation method to extract the volatile oil in the medicinal material, taking the response value of the volatile oil extraction rate of the angelica medicinal material, selecting the soaking time, the water ...

Abstract

The invention discloses a method for optimizing parameters of an angelica sinensis essential oil extracting process based on a response surface methodology. By virtue of a steam distillation method, soaking time, a liquid-solid mass ratio and extracting time, which have relatively great influence on the oil extracting amount, are selected on the basis of a single-factor test for investigation; a quadratic polynomial equation model, which shows a relation between the oil extracting amount and three factors, is established by virtue of the response surface methodology; and a three-dimensional surface figure is drawn and is analyzed comprehensively, so as to obtain optimal technological conditions: the soaking time is 5h, the liquid-solid mass ratio is 12: 1 and the extracting time is 9h. The method provided by the invention, on the basis of central composite design and response surface analysis, can conduct an optimal experiment and data analysis conveniently and reliably by virtue of statistical software Design Expert7.0.0, and the technological parameters of extracting essential oil from 'Mingui No.3' are optimized so as to achieve a relatively good effect. The method provided by the invention provides a reference for evaluating inherent quality of the 'Mingui No.3' and lays a foundation for the popularization and the application of a novel angelica sinensis variety.

Description

technical field [0001] The invention relates to the technical field of plant component extraction, in particular to a method for optimizing process parameters of angelica volatile oil extraction based on response surface method. Background technique [0002] Angelica sinensis is the root of Angelica sinensis (Oliv.) Diels of Umbelliferae. It enters the liver, heart, and spleen meridians. It has sweet, pungent, and warm medicinal properties. One of the highest traditional Chinese medicines, known as "ten directions and nine returns". The chemical composition of angelica is mainly volatile oil and water-soluble components. Angelica volatile oil has a wide range of pharmacological activities on the body's uterine smooth muscle, central nervous system and immune system, and has anti-asthma, analgesic, anti-anxiety and other effects. Angelica is mainly produced in Gansu, especially the angelica produced in Minxian County, which is fragrant, oily, and of good quality, and is com...
