preparation example Construction

[0018] The preparation method of a kind of Chinese medicine composition volatile oil provided by the embodiment of the present invention, it comprises:

[0019] Using supercritical CO 2 Extract raw materials, at 25MPa~30MPa, 40~60℃, CO 2 The flow rate is 6-10 kg / h and the extraction is 60-120 min; the raw materials include 25-35 parts by weight of cardamom, 15-25 parts by weight of pepper and / or pepper, 14-26 parts by weight of cumin, and 20-35 parts by weight of cumin; cardamom including at least one of cardamom and nutmeg. Preferably, at 30MPa, 50°C, CO 2 Extract for 100min at a flow rate of 8kg / h.

[0020] Cardamom is warm and pungent in nature and has the effects of warming the spleen and invigorating the stomach, regulating Qi and promoting digestion. In this example, the cardamom comprises cardamom and / or nutmeg. White cardamom (Fmctus Amomi Rotundus) is the dry ripe fruit of the plant Cardamom genus Zingiberaceae. Nutmeg (Semen Myristicae) is the dry mature seed o...

Abstract

The invention discloses a preparation method for traditional Chinese medicine composition volatile oil. The preparation method is characterized in that supercritical CO2 extraction is performed for 60-120 minutes on raw materials under pressure of 25-30 MPa at a temperature of 40-60 DEG C, wherein CO2 flow is 6-10 kg / h; and the raw materials comprise fructus amomi rotundus with rich volatile oil active ingredient, black pepper, long pepper as well as at least one of cumin, fennel and caraway. Traditional Chinese medicine composition raw materials are extracted through supercritical CO2, and corresponding parameters are strictly controlled, so that the oil yield of volatile oil of the traditional Chinese medicine composition can be highest. When the traditional Chinese medicine composition is in the proportion, supercritical CO2 extraction is performed on the raw materials, so that the oil yield is increased. Traditional Chinese medicine composition volatile oil is prepared from the preparation method of the traditional Chinese medicine composition volatile oil. The volatile oil is strong in pharmacologic action. A method for preparing the traditional Chinese medicine composition comprises the preparation method of the traditional Chinese medicine composition volatile oil. The method can remarkably improve the curative effect of the traditional Chinese medicine composition.

Description

technical field [0001] The invention relates to the field of medicine, and in particular to a Chinese medicine composition volatile oil, a preparation method thereof, and a method for preparing the Chinese medicine composition. Background technique [0002] Volatile oil, also known as essential oil, is a kind of volatile oily liquid that can be distilled out with water vapor. Most of them have aroma, such as peppermint oil and clove oil. There are many Chinese herbal medicines containing volatile oil, and many of them are aromatic, especially those of Labiatae, Umbelliferae, Compositae, Rutaceae, Lauraceae, Zingiberaceae and other families. Most of the Chinese herbal medicines containing volatile oil or the extracted volatile oil have the effects of sweating, regulating qi, relieving pain, inhibiting bacteria, and correcting flavor. Methods for extracting volatile oil include steam distillation, leaching, and cold pressing. Usually extracting volatile oil is the method of ...
