Embodiment Construction

[0022] A method for extracting and separating spices and medicinal components from the whole herb of the plant Shennong Fragrant Chrysanthemum, the steps of which are:

[0023] 1. Steam Distillation of Shennong Fragrant Chrysanthemum 1: Air-dry 100kg of Shennong Fragrant Chrysanthemum after flowering, cut into one-inch-long materials, put them in a 2-hour still, add 10-30kg of water into the still (still Both the interlayer and the still can pass water vapor), open the water vapor valve leading to the still for distillation, and turn off the interlayer steam path valve. When the temperature in the kettle reaches 95-105°C, record the distillation time as 1-2 hours, and the generated mixed steam enters the oil-water separator through the cooling tower, and the essential oil is initially collected.

[0024] 2. Refining of essential oil 2: The initially collected essential oil contains water and emulsified components, which need to be further separated. Put the separatory funnel ...

Abstract

The invention discloses a method for producing, extracting and separating spice and medicinal components from whole plants of Dendranthema indicum, which comprises the following steps of: A, steam distillation of the Dendranthema indicum, namely air-drying the whole plants of bloomed Dendranthema indicum, putting the air-dried whole plants into a distillation still and collecting essential oil; B, refining, namely separating water from an emulsified ingredient which are contained in the collected essential oil and combining the product with an oil layer in a separatory funnel; C, preparation of an ethanol extract, namely closing a valve which directly pumps steam in the distillation still, opening a sandwich steam valve communicated with the distillation still, heating, combining and pumping the product to an extraction pot; D, preparation of an ethyl acetate extract, namely stirring and suspending ethanol concentrate in the extraction pot with hot water, extracting with ethyl acetate and drying; and E, preparation of a medicinal compound by column chromatography, namely uniformly spreading silica gel mixed with the ethyl acetate extract on silica gel in a column and carrying out elution to obtain the medicinal components. The method is simple, is convenient to operate, and is used in the industries of medicine, food and tobacco; and aroma and the medicinal components of the Dendranthema indicum can be easily, rapidly and economically given off and prepared.

Description
