Abstract

The invention relates to a method for extracting volatile oil from Ziziphora Clinopodioides Lam herb by CO2 supercritical extraction technique, comprising the steps of: cleaning and drying the Ziziphora Clinopodioides Lam herb at normal temperature, disintegrating by a disintegrator, sieving to obtain Ziziphora Clinopodioides Lam herb powder, putting the Ziziphora Clinopodioides Lam herb powder in an extraction cylinder for extraction, and then discharging the volatile oil through discharging holes of a separation cylinder I and a separation cylinder II. The invention, in no need of any solvent, can be implemented at normal temperature with CO2 being non-toxic and residual-free, and the invention is low in energy consumption, stable in gas source, recyclable, simple in extraction technology and high in extraction efficiency; the yield of the volatile oil thereof can run up to over 1.8%. The invention overcomes the disadvantages that the traditional steam distillation method used for extracting the volatile oil from the Ziziphora Clinopodioides Lam wastes a lot of time and energy and residual moisture is present in the product.

Description

technical field [0001] The invention relates to a method for extracting the volatile oil of effective components from the whole grass of Xintahua plant. Background technique [0002] Z bungeana Juz (Z bungeana Juz) is a sub-shrub herb with a strong mint fragrance. It is mainly produced in the Altai Mountains, Tianshan Mountains, Western Junggar Mountains, Pamirs and Kunlun Mountains in Xinjiang. Mountain grasslands and gravel slopes are also distributed in Central Asia and Mongolia. Fragrant new tower flower is a folk Chinese herbal medicine and a commonly used national medicine. It is called Xuze or Suze in Xinjiang Uyghur medicine. It is mainly used for the treatment of hypertension and coronary heart disease and to regulate the function of the cardiovascular system. Its active ingredients are mainly volatile oil, Flavonoids, alkaloids and vitamin C and other ingredients. [0003] Twenty-nine chemical constituents were identified from the volatile oil of Aromaxinta flowe...
